Testicular cancer is a type of cancer that begins in the testicles, the two small organs inside the scrotum that produce sperm and the hormone testosterone. Although it is not as common as other cancers, it tends to affect younger men (often between 15 and 35 years old). Early detection and treatment are key to a good outcome.
Testicular cancer forms when abnormal cells grow uncontrollably in one or both testicles. These cells may form a mass or lump that can be felt during self-examination. Even though testicular cancer is rare compared to other cancers, it is the most common cancer in younger men. With modern treatments, the survival rate is high when the cancer is caught early.
Pathophysiology of Testicular Cancer
Understanding how testicular cancer develops starts with knowing about the testicles’ structure, blood and nerve supply, and functions.
Structure
Testicles Anatomy:
The testicles are oval-shaped organs contained in a skin pouch called the scrotum. Each testicle is surrounded by a protective covering known as the tunica albuginea. Inside, tiny tubes called seminiferous tubules produce sperm. Other cells, such as Leydig cells, are responsible for producing testosterone.Supportive Structures:
The epididymis sits on the back of each testicle and stores sperm until they are ready to be ejaculated. The spermatic cord holds the testicle in place and contains blood vessels, nerves, and the vas deferens (the tube that carries sperm).
Blood Supply
Arterial Supply:
Blood is delivered to the testicles mainly by the testicular arteries, which branch directly from the aorta (the body’s main artery). This rich blood supply is important because it delivers oxygen and nutrients necessary for sperm production.Venous Drainage:
The blood leaves the testicles through a network of veins known as the pampiniform plexus. This network helps cool the blood before it reaches the testicles, which is important for proper sperm production.
Nerve Supply
- Nervous Connections:
The testicles are supplied by both sympathetic and parasympathetic nerves. These nerves help control functions such as blood flow and sensations like pain. When cancer develops, nerve involvement may lead to discomfort or pain.
Functions
Sperm Production:
The main function of the testicles is to produce sperm, which are necessary for reproduction.Hormone Production:
They also produce testosterone, which plays a key role in the development of male characteristics, muscle mass, and libido.
Understanding the anatomy and function of the testicles helps explain why any abnormal growth in this area can affect both fertility and hormonal balance.
Types of Testicular Cancer
There are several types of testicular cancer, and they are mainly divided into two broad categories:
Germ Cell Tumors
These account for about 95% of testicular cancers and develop from the cells that produce sperm.
- Seminomas:
These tumors tend to grow slowly and are very sensitive to radiation therapy. - Non-Seminomas:
This group includes several different types such as:- Embryonal Carcinoma
- Yolk Sac Tumor
- Choriocarcinoma
- Teratoma
Non-seminomas are usually more aggressive and may require a combination of treatments.
Non-Germ Cell Tumors
These are less common and include:
- Leydig Cell Tumors:
Arise from the hormone-producing cells and can sometimes cause changes in hormone levels. - Sertoli Cell Tumors:
These develop in the supportive cells of the testicle and are generally less aggressive. - Testicular Lymphoma:
More common in older men, this type is not a germ cell tumor but a cancer of the lymph tissue.
Each type has its own characteristics, treatment options, and prognosis. Early diagnosis and proper classification help guide the best treatment approach.
Causes and Risk Factors
While the exact cause of testicular cancer is not fully understood, several factors may increase a man’s risk of developing the disease. Here are 20 potential causes and risk factors:
- Undescended Testicle (Cryptorchidism):
A testicle that has not descended properly increases the risk. - Family History:
Having a close relative with testicular cancer raises your risk. - Age:
Most common in men aged 15-35. - Personal History:
A history of testicular cancer in one testicle increases the chance of it developing in the other. - Abnormal Testicular Development:
Developmental issues with testicles can be a factor. - Genetic Factors:
Certain genetic changes may predispose individuals to testicular cancer. - Klinefelter Syndrome:
This genetic condition can increase risk. - Hormonal Imbalance:
Abnormal levels of hormones, especially during development, may contribute. - Exposure to Estrogens in Utero:
High exposure to female hormones during pregnancy might be linked. - Environmental Toxins:
Contact with certain chemicals may increase risk. - Radiation Exposure:
Past exposure to radiation can be a risk factor. - Testicular Trauma:
Although less clear, injury to the testicles might be linked to later cancer. - Infections (e.g., Mumps Orchitis):
Inflammation from infections may play a role. - Chronic Inflammation:
Persistent inflammation in the testicular area can be a factor. - Lifestyle Factors:
Poor diet, lack of exercise, or obesity may indirectly influence risk. - Smoking:
Tobacco use has been linked to a higher risk of various cancers. - Alcohol Consumption:
Excessive drinking may have an indirect effect. - Occupational Exposures:
Jobs that expose workers to high levels of chemicals or toxins might increase risk. - Immune System Problems:
Conditions that weaken the immune system can play a role. - Race and Ethnicity:
Testicular cancer is more common in white men compared to men of other races.
Understanding these factors can help with early detection and preventive measures.
Symptoms of Testicular Cancer
The symptoms of testicular cancer can vary from person to person. Here are 20 possible symptoms to be aware of:
- A Painless Lump or Swelling:
Often the first sign, a small lump on the testicle may be felt. - Enlarged Testicle:
One testicle may appear bigger than the other. - Dull Ache in the Groin or Abdomen:
Persistent discomfort in the lower abdomen or groin area. - Sharp Pain in the Testicle:
Pain may develop in or around the testicle. - Heaviness in the Scrotum:

When to See a Doctor
It is important to seek medical advice if you notice any signs or symptoms that could indicate testicular cancer. Consider seeing a doctor if:
- You discover a lump or swelling in one or both testicles.
- You feel any persistent pain or discomfort in the scrotum, groin, or lower abdomen.
- There is a noticeable change in the size, shape, or texture of a testicle.
- You experience unexplained fatigue, weight loss, or other general symptoms.
- You find swollen lymph nodes in your groin or neck.
- You experience pain during intercourse or other activities.
- Your self-examination reveals any unusual changes that continue or worsen over time.
Early diagnosis is critical. If you’re unsure, it’s always best to get evaluated by a healthcare professional.
