Low malignant potential (LMP) ovarian tumor (also called a borderline ovarian tumor) is a growth that looks abnormal under the microscope but does not behave like typical cancer. It tends to grow slowly, rarely invades nearby tissues, and is much less likely to spread compared with invasive ovarian cancer. Most people do well after surgery, especially when the tumor is found early. In many cases, surgery alone is enough, and chemotherapy is not routinely needed. Cancer.gov+1
A low malignant potential (LMP) ovarian tumor—now most often called a borderline ovarian tumor (BOT)—is an epithelial tumor of the ovary that shows extra cell growth and atypia under the microscope, but does not invade nearby tissue the way true cancer does. Because there is no destructive invasion, these tumors usually have a much better outlook than invasive ovarian cancer. Most are found early (stage I) and are treated mainly with surgery. Care still matters because a small number can recur or, rarely, progress. Cancer.gov+1
Doctors diagnose and stage LMP tumors using surgery and pathology. Follow-up usually includes pelvic exams and periodic imaging; tumor markers may be used in select cases but are less reliable than in invasive disease. Fertility-sparing surgery can be considered for people who want a future pregnancy, with a plan for careful surveillance. Cancer.gov
Other names
-
Borderline ovarian tumor (preferred, modern term)
-
Tumor of low malignant potential (LMP)
-
Atypical proliferative tumor (older pathology wording)
All three describe the same general group of non-invasive epithelial ovarian tumors. bccancer.bc.ca+1
Types
Doctors classify borderline tumors by the cell type and by certain growth patterns seen under the microscope:
-
Serous borderline tumor (SBT) – the most common; sometimes shows a micropapillary pattern, which needs closer follow-up.
-
Mucinous borderline tumor (MBT) – can be intestinal-type or endocervical-type; these are often large cystic masses.
-
Endometrioid borderline tumor – linked to endometriosis in some patients.
-
Seromucinous (mixed) borderline tumor – shows both serous- and mucinous-like areas and often coexists with endometriosis.
-
Clear cell borderline tumor – rare.
-
Borderline tumor with microinvasion – shows tiny foci of invasion but behaves much better than invasive carcinoma; needs careful staging and follow-up.
Pathologists sometimes add molecular notes (for example, KRAS or BRAF mutations in serous/mucinous lesions). Staging follows FIGO rules used for ovarian tumors in general. PMC+2annalsofoncology.org+2
Borderline tumors make up roughly 15–20% of epithelial ovarian tumors. They are often diagnosed younger than invasive ovarian cancer—many patients are in their 40s and 70%–75% are stage I at diagnosis. Prognosis is generally excellent after proper surgery. Cancer.gov+2bccancer.bc.ca+2
Possible causes
We rarely know a single “cause.” Instead, these are associations or mechanisms that may contribute. Not every patient will have any of these.
-
Ovulatory lifetime exposure – more total ovulations may increase epithelial stress and mutation chance. Fewer ovulations (pregnancy, birth control pills) may lower risk. ACOG
-
Endometriosis – especially tied to seromucinous and endometrioid borderline types. annalsofoncology.org
-
Somatic gene changes (e.g., KRAS, BRAF) – common driver mutations in serous and mucinous borderline tumors; they affect cell-growth signaling. annalsofoncology.org
-
Hormonal environment – estrogen-dominant states may stimulate target epithelium over time (mechanism proposed, not proven causation). annalsofoncology.org
-
Nulliparity (no prior births) – reflects higher ovulatory cycles and associated risk. ACOG
-
Infertility or ovulation-induction history – data are mixed; some series suggest a small increase in borderline tumors. ACOG
-
Smoking – particularly associated with mucinous ovarian tumors (including borderline). Society of Gynecologic Oncology
-
Personal history of endometrial pathology – overlaps in some borderline histologies. annalsofoncology.org
-
Pelvic inflammation – chronic irritation is a theorized promoter for epithelial change. PMC
-
Genetic susceptibility outside BRCA – classic BRCA links are weak for borderline and mucinous types; most are not BRCA-driven. Society of Gynecologic Oncology
-
Environmental exposures – unproven; studied as part of ovarian neoplasm epidemiology. PubMed
-
Obesity and metabolic factors – may shift estrogen and inflammatory pathways. annalsofoncology.org
-
Early menarche/late menopause – more ovulations across life. ACOG
-
Benign cystadenomas as precursors – stepwise change to atypical proliferative (borderline) epithelium is proposed in mucinous lesions. PMC
-
Prior pelvic surgery with residual implants – rarely, borderline-type implants can arise; association more than cause. PMC
-
Low-grade serous pathway – borderline serous tumors fit a “low-grade” pathway distinct from high-grade serous carcinoma. annalsofoncology.org
-
Ovarian cyst persistence – long-standing cystic epithelium may accumulate mutations. PMC
-
Hormone replacement therapy (HRT) – evidence mixed; any risk, if present, appears small and not clearly causal for borderline tumors. annalsofoncology.org
-
Familial non-BRCA patterns – very uncommon; most borderline tumors are sporadic. exxcellence.org
-
Field effect in Müllerian epithelium – shared biology between ovarian, tubal, and peritoneal epithelium can permit atypical proliferations without invasion. annalsofoncology.org
Common symptoms
-
Bloating or fullness – fluid or a large cyst can stretch the belly.
-
Lower tummy (pelvic) pain or pressure – the ovary sits low in the pelvis; a mass can press on nearby organs.
-
Belly swelling – size of the cyst or, less often, fluid (ascites).
-
Frequent urination – pressure on the bladder.
-
Early fullness while eating – pressure on the stomach area.
-
Constipation or bowel changes – pressure on the rectum or colon.
-
Irregular periods – less common, but hormonal effects or stress can alter cycles.
-
Pain with sex – pressure or pulling on pelvic structures.
-
Low back discomfort – referred pain from a pelvic mass.
-
Unexplained weight change – from a large cyst or reduced appetite.
-
Fatigue – non-specific; chronic symptoms can wear you down.
-
Palpable mass – sometimes a doctor can feel an adnexal mass on exam.
-
Nausea/indigestion – mass effect on the stomach or bowels.
-
Shortness of breath – rare, from very large masses or fluid under the diaphragm.
-
Infertility concerns – some patients learn about the mass during fertility workups.
(These are similar to symptoms seen with many adnexal masses; borderline tumors often present earlier and behave more indolently than invasive cancer.) ACOG+1
Diagnostic tests
Key idea: No single blood test can diagnose a borderline tumor. Doctors use history, exam, imaging, tumor markers, and—most importantly—pathology from surgery. Staging follows FIGO rules. ACOG+2Cancer.gov+2
A) Physical examination (what the clinician sees or feels)
-
General exam and symptom review
Your clinician asks about bloating, pain, periods, and weight change, and checks your abdomen for swelling or tenderness. This helps judge urgency and plan imaging. ACOG -
Abdominal palpation
Hands-on belly exam can sometimes feel a large mass or fluid. While not precise, it guides the next steps (ultrasound, labs). ACOG
B) “Manual” pelvic evaluation (hands-on gynecologic exam)
-
Speculum exam
The speculum allows the doctor to see the cervix and vaginal walls. It doesn’t diagnose an ovarian mass directly but rules out visible cervical or vaginal causes of bleeding or pain. ACOG -
Bimanual pelvic exam
One hand in the vagina and one on the abdomen lets the clinician feel the uterus and adnexa. A fullness or mobile cystic mass may be noted, prompting imaging. ACOG -
Rectovaginal exam (as needed)
A finger in the rectum and vagina at the same time can better assess the posterior pelvis, uterosacral ligaments, and cul-de-sac for masses or nodules. ACOG
C) Laboratory & pathology (the decisive category)
-
CA-125 blood test
This tumor marker is not specific, but in postmenopausal patients or with concerning imaging, a raised CA-125 increases suspicion. Many borderline tumors have normal or only mildly elevated CA-125. It cannot confirm cancer on its own. ACOG -
HE4 and multivariate risk indices (e.g., ROMA)
In some settings, HE4 helps triage an adnexal mass, but results must be read with imaging and clinical findings. Borderline tumors may not push markers very high. ACOG -
Other markers to narrow the differential
CEA, CA19-9, inhibin, AFP, β-hCG, and LDH can help distinguish mucinous tumors or non-epithelial masses (like germ-cell tumors) when imaging is unclear. These do not prove a borderline tumor but help rule things in or out. ACOG -
Complete blood count & chemistry panel
These tests check anemia, infection signs, and organ function to plan safe surgery and anesthesia. ACOG -
Intra-operative frozen section
During surgery, the pathologist can examine a small piece quickly to guide the extent of surgery (for example, to consider fertility-sparing steps). Frozen section is useful but not perfect; final diagnosis still relies on permanent sections. PMC -
Definitive histopathology (permanent sections)
This is the gold standard. The pathologist looks for epithelial proliferation and atypia without destructive stromal invasion to confirm a borderline tumor and its specific type (serous, mucinous, etc.). PMC -
Cytology of peritoneal washings
At staging surgery, washings look for free tumor cells in the abdominal cavity; results contribute to FIGO staging. Society of Gynecologic Oncology -
Immunohistochemistry & molecular testing (when needed)
Markers such as WT1, PAX8, CK7, ER/PR, and molecular profiling (e.g., KRAS/BRAF) help confirm tumor origin and subtype, especially in tricky cases. annalsofoncology.org
D) Imaging tests (to characterize the mass and stage)
-
Transvaginal ultrasound (TVUS)
This is the first-line imaging test. It shows whether a mass is cystic, solid, or mixed, and can display septations, papillary projections, or nodules that raise concern for borderline features. Structured approaches (like IOTA rules) improve accuracy. ACOG -
Color Doppler ultrasound
Assesses blood flow in septa or papillary areas. Increased internal vascularity can raise suspicion and guide the surgical plan. ACOG -
MRI of the pelvis
MRI helps when ultrasound is uncertain. It can better show papillary excrescences, mural nodules, and the relationship to nearby organs, and it avoids radiation. ACOG -
CT scan of abdomen/pelvis
CT helps plan surgery for very large masses or to look for implants or lymph nodes when staging is needed. CT is commonly used in pre-operative workups. Cancer.gov -
Chest imaging (X-ray or CT as indicated)
Used to complete staging or evaluate symptoms. Borderline tumors rarely spread to the chest, but imaging can be appropriate in selected cases. Cancer.gov -
PET-CT (select cases)
PET-CT is not routine for borderline tumors but may be used if there is confusing or recurrent disease where metabolic information will change management. annalsofoncology.org
E) “Electrodiagnostic” tests (important note)
-
No electrodiagnostic test diagnoses borderline ovarian tumor
Electrodiagnostic studies like EMG or nerve-conduction tests are not used for ovarian masses. Pre-operative ECG may be done to assess heart safety for anesthesia, but it does not help diagnose the tumor. This category is essentially not applicable for ovarian borderline tumors. annalsofoncology.org+1
Non-pharmacological treatments (therapies and other supports)
-
Shared decision-making & second opinion (gynecologic oncology)
Description (≈150 words): Because LMP tumors often have excellent outcomes with surgery alone, treatment choices should carefully balance benefits and side effects. A consultation with a gynecologic oncologist clarifies whether conservative (fertility-sparing) surgery or more extensive surgery is best, and whether any additional therapy is needed. Getting a second opinion helps confirm the diagnosis because pathology interpretation can be challenging in borderline tumors. This collaborative process also sets up a personalized surveillance plan and clarifies warning signs to watch for.
Purpose: Choose the least-harm, most-effective plan for your goals (cure, fertility, quality of life).
Mechanism: Expert review of imaging, operative notes, and pathology; risk stratification; evidence-guided follow-up. Cancer.gov -
Fertility counseling
Description: Many people with LMP tumors are diagnosed in their reproductive years. A reproductive specialist can explain options like oocyte or embryo cryopreservation before surgery, or fertility-sparing procedures (such as unilateral salpingo-oophorectomy or cystectomy when appropriate). Counseling also covers timing of pregnancy and how future monitoring will work during and after fertility treatment.
Purpose: Preserve the possibility of biological parenthood and plan safe timing.
Mechanism: Aligns surgical approach and follow-up with reproductive goals while maintaining oncologic safety. Cancer.gov -
Structured surveillance program
Description: After surgery, most patients are followed with scheduled pelvic exams and imaging at defined intervals. Blood markers may be used selectively, but imaging and clinical review are more informative for LMP tumors. A written schedule reduces anxiety and supports early detection of rare recurrences.
Purpose: Detect recurrence early and maintain peace of mind.
Mechanism: Risk-adapted follow-up using exam and imaging at set time points. Cancer.gov -
Pelvic floor physical therapy (PFPT)
Description: Surgery can lead to pelvic pain, scar-related tightness, or dyspareunia (pain with intercourse). PFPT uses gentle manual techniques, relaxation, stretching, and home exercises to restore mobility and reduce pain. Therapists also teach bladder/bowel strategies after pelvic surgery.
Purpose: Reduce pelvic pain and improve function and sexual comfort.
Mechanism: Targeted myofascial release, graded exposure, and neuromuscular retraining. Cancer.gov -
Psychosocial support & evidence-based coping (CBT/mindfulness)
Description: A new tumor diagnosis can bring fear and uncertainty. Cognitive behavioral strategies and mindfulness can lessen anxiety, improve sleep, and help with treatment decisions. Support groups (in-person or virtual) provide community and practical tips.
Purpose: Improve quality of life and reduce distress.
Mechanism: Skills that calm the stress response and reframe unhelpful thoughts. Cancer.gov -
Sexual health counseling
Description: Hormonal shifts, surgical changes, and anxiety can affect desire, arousal, and comfort. A clinician can discuss lubricants, vaginal moisturizers, positions, and when to consider pelvic floor therapy or medical options. Partners can be included to improve communication.
Purpose: Restore pleasurable, pain-free intimacy.
Mechanism: Education, gradual return plans, and symptom-directed strategies. Cancer.gov -
Exercise (aerobic + strength, tailored)
Description: Regular activity improves fatigue, mood, and cardiometabolic health after surgery. Start with light walking and progressive resistance training under guidance if needed.
Purpose: Boost energy, function, and long-term health; lower treatment-related fatigue.
Mechanism: Improves cardiorespiratory fitness, muscle strength, and insulin sensitivity. Cancer.gov -
Nutrition counseling (whole-food pattern)
Description: Emphasize vegetables, fruits, whole grains, legumes, nuts, and lean proteins; limit ultra-processed foods, excess sugar, and alcohol. Registered dietitians can individualize plans for weight stability, bowel comfort, and iron/fiber balance post-op.
Purpose: Support healing and overall well-being.
Mechanism: Provides micronutrients, fiber, and balanced macros; stabilizes energy and bowel function. Cancer.gov -
Acupuncture for postoperative symptoms
Description: Some patients find acupuncture helps with postoperative nausea, pain, or stress; it is considered an optional, complementary therapy when performed by licensed practitioners.
Purpose: Reduce selected symptoms and improve relaxation.
Mechanism: Neuromodulation and endogenous endorphin release; placebo and expectancy effects may contribute. Cancer.gov -
Quit smoking & limit alcohol
Description: If you smoke, quitting improves wound healing and long-term health; alcohol limitation supports sleep, mood, and liver health.
Purpose: Lower complications and improve overall outcomes.
Mechanism: Reduces inflammation and toxins that impair recovery. Cancer.gov -
Sleep hygiene program

Pain self-management toolkit
Description: Combine scheduled non-opioid pain relievers (per clinician advice), heat/ice, gentle stretching, and pacing. Learn “flare plans” for activity.
Purpose: Control discomfort while minimizing sedating medicines.
Mechanism: Multimodal strategies reduce nociception and central sensitization. Cancer.gov -
Body-image and scar-care support
Description: Silicone gels/sheets, sun protection, and massage help the scar mature. Counseling addresses body-image changes after pelvic surgery.
Purpose: Improve comfort with one’s body and scar quality.
Mechanism: Topical occlusion and gentle remodeling of scar tissue. Cancer.gov -
Return-to-work/role planning

Surgeries
-
Unilateral salpingo-oophorectomy (USO)
Procedure: Removal of the ovary and fallopian tube on the affected side.
Why: Standard for many early LMP tumors in people desiring future fertility; removes tumor while preserving the other ovary and the uterus. Cancer.gov -
Cystectomy (ovarian cyst removal)
Procedure: Removes only the cyst/tumor, leaving as much normal ovary as possible.
Why: Option for very select, small, well-defined LMP tumors with a strong desire to preserve fertility; requires close follow-up. Cancer.gov -
Bilateral salpingo-oophorectomy (BSO)
Procedure: Removes both ovaries and tubes.
Why: Considered when childbearing is complete, when disease involves both ovaries, or when risk reduction is preferred. Cancer.gov -
Comprehensive surgical staging
Procedure: Careful inspection of the abdomen/pelvis, peritoneal washings, biopsies, and sometimes omentectomy.
Why: Confirms stage, detects implants, and guides need for any further care. Cancer.gov -
Completion surgery
Procedure: After fertility is achieved or when risk-benefit shifts, the remaining ovary/tube (and sometimes uterus) may be removed.
Why: Reduces future recurrence risk in selected cases. Cancer.gov
Preventions
-
Do regular gynecologic visits and follow the surveillance plan your team recommends. Cancer.gov
-
Know and act on new symptoms (bloating, pelvic pain, early fullness, changes in periods). Cancer.gov
-
Do not smoke; seek help to quit if you do. Cancer.gov
-
Maintain a healthy, whole-food dietary pattern and steady weight. Cancer.gov
-
Stay physically active most days of the week. Cancer.gov
-
Keep vaccinations current (especially flu/COVID-19). Cancer.gov
-
Manage stress with mindfulness or counseling to improve sleep and coping. Cancer.gov
-
Discuss family history; consider genetic counseling if indicated. Cancer.gov
-
Use reliable medical sources (like NCI PDQ) for information; avoid unregulated treatments. Cancer.gov
-
Follow pre- and post-operative instructions carefully to reduce complications. Cancer.gov
When to see a doctor urgently
Contact your care team right away if you have any of the following: new or worsening pelvic/abdominal pain, severe bloating or rapidly increasing girth, vomiting that won’t stop, fever or chills, vaginal bleeding that is heavy or unexpected, leg swelling or calf pain, chest pain or shortness of breath, or any new, persistent symptom that worries you. These symptoms may be unrelated—or signal a complication or recurrence—and are safest evaluated promptly. Cancer.gov
What to eat and what to avoid
What to eat :
-
Plenty of vegetables and fruits daily (aim for color variety).
-
Whole grains and legumes for fiber and steady energy.
-
Lean proteins (fish, poultry, tofu, beans) to support healing.
-
Healthy fats (olive oil, nuts, seeds).
-
Enough fluids (mostly water) to stay hydrated. Cancer.gov
What to limit/avoid :
-
Ultra-processed foods high in added sugars.
-
Excess alcohol.
-
Large amounts of red/processed meats.
-
Smoking and nicotine products.
-
High-dose supplements without clinician guidance (risk of interactions). Cancer.gov
Frequently asked questions (FAQs)
-
Is an LMP ovarian tumor “cancer”?
No. It has abnormal cells with borderline features but lacks destructive invasion seen in cancer. Outcomes are generally excellent, especially with early, complete surgery. Cancer.gov -
Do I always need chemotherapy?
Usually no. Most LMP tumors are treated with surgery alone. Chemo or targeted drugs are reserved for unusual, advanced, or recurrent scenarios and decided by a gynecologic oncologist. Cancer.gov -
Can I keep my fertility?
Often yes. Many people have fertility-sparing surgery with careful follow-up. Discuss your goals before surgery. Cancer.gov -
How often will I need check-ups after surgery?
Your team will create a schedule of pelvic exams and imaging at set intervals, adjusting over time. Cancer.gov -
Are blood tests like CA-125 reliable for LMP?
They may be used selectively, but they’re less useful than in invasive ovarian cancer; imaging and exams matter more. Cancer.gov -
What if my pathology says “implants”?
Your surgeon will explain whether implants are non-invasive or invasive; this influences staging, prognosis, and surveillance intensity. Cancer.gov -
Do PARP inhibitors (like olaparib) apply to LMP?
They are approved for epithelial ovarian cancer scenarios (e.g., maintenance after platinum response, BRCA/HRD-positive disease), but not standard for classic LMP. FDA Access Data -
Is bevacizumab (Avastin) used for LMP?
It’s used in epithelial ovarian cancer; for LMP it’s not routine and would be considered only in special circumstances and clinical trials. FDA Access Data -
Do growth-factor shots treat the tumor?
No. Agents like filgrastim or pegfilgrastim only help white blood cells recover during chemo; they don’t kill tumor cells. FDA Access Data+1 -
Are there approved stem-cell treatments for LMP ovarian tumors?
No. Avoid unregulated “stem-cell” clinics; ask about legitimate clinical trials if interested. Cancer.gov -
What lifestyle steps help recovery?
Regular activity, whole-food nutrition, good sleep, and stress-reduction improve energy and well-being after surgery. Cancer.gov -
Will I need hormone therapy?
Hormone therapy isn’t standard for LMP, though endocrine drugs are sometimes tried off-label for select recurrences. Discuss risks and benefits with your oncologist. FDA Access Data+1 -
How long is follow-up needed?
Your team will outline a multi-year plan since late recurrences are uncommon but possible; schedules are individualized. Cancer.gov -
What warning signs should I never ignore?
New or worsening abdominal/pelvic pain, severe bloating, vomiting, fever, heavy bleeding, chest pain, or shortness of breath—seek care promptly. Cancer.gov -
Where can I read reliable, up-to-date information?
Start with the NCI PDQ pages on ovarian borderline tumors (patient and professional versions). Cancer.gov+1
