Small cell carcinoma is a type of aggressive cancer that can occur in various parts of the body. It is a type of cancer that begins in certain cells within the body. It’s mostly found in the lungs but can appear elsewhere. Imagine the body as a city, SCC would be like unwanted constructions in specific neighborhoods. Though it can pop up in various parts, most people hear about SCC in the context of lung cancer, termed “Small Cell Lung Cancer” (SCLC). Picture the lungs as two big tree branches with numerous smaller branches. These branches should remain open and clear, but SCC builds obstructions, making breathing hard.
When scientists look at these cancer cells under a microscope, they appear smaller than usual. It’s like comparing tiny toy cars to regular-sized ones – both are cars, but one is notably smaller.
Types
Types of Small Cell Carcinoma
- Small Cell Lung Cancer (SCLC)
- What it is: This is the most common form of SCC. When someone mentions small cell carcinoma, they often mean this type.
- Simple explanation: Imagine your lungs having some tiny bad cells. These cells grow faster than normal cells and can spread to other parts of the body quickly. Small Cell Lung Cancer or SCLC is the major player in the SCC category. Understanding its rapid growth is key to early detection and treatment.
- Extrapulmonary Small Cell Carcinoma (EPSCC)
- What it is: It’s SCC, but not in the lungs. Instead, it’s in other parts of the body.
- Simple explanation: Sometimes those bad tiny cells show up in places other than the lungs, like the bladder, prostate, or even the skin. Extrapulmonary Small Cell Carcinoma, known as EPSCC, is the surprise guest. It reminds us that SCC doesn’t just stick to the lungs.
- Combined Small Cell Carcinoma
- What it is: It’s a mix. This cancer has features of both SCC and non-small cell cancers.
- Simple explanation: Imagine if those tiny bad cells teamed up with other bad cells. That’s the combined version. Combined Small Cell Carcinoma is like the plot twist in our SCC story. Recognizing this blend can influence treatment decisions.
- Large Cell Neuroendocrine Carcinoma
- What it is: It’s like SCC but slightly bigger. Though it’s called ‘large’, it’s still pretty small.
- Simple explanation: Think of it as a cousin to the small cells. They’re similar but not identical. Large Cell Neuroendocrine Carcinoma showcases that in the world of tiny cells, some are just a tad bit bigger but equally important.
Causes
Potential causes in plain English. Let’s delve into them.
1. Smoking: The top culprit. When you smoke, harmful chemicals enter your lungs, increasing cancer risk.
2. Secondhand Smoke: Even if you don’t smoke, inhaling someone else’s smoke can harm your cells, making cancer more likely.
3. Family History: If close family members had this cancer, your risk might be higher.
4. Radiation Exposure: Being around radiation, maybe from previous cancer treatments, can up your risk.
5. Asbestos Exposure: Asbestos is a material once popular in construction. Breathing it in can cause lung problems, including cancer.
6. Radon Exposure: This invisible gas, which can enter homes, is a sneaky risk for lung cancers.
7. Air Pollution: Constant exposure to polluted air can harm your lungs over time.
8. Occupational Exposures: Jobs involving coal, arsenic, or diesel exhaust may increase your risk.
9. Advanced Age: The older you get, the higher the chance of developing this cancer.
10. Prior Lung Diseases: If you’ve had lung problems like tuberculosis (TB), your risk is slightly higher.
11. Excessive Alcohol Intake: Regular heavy drinking might raise the possibility of small cell carcinoma.
12. Certain Metals: Being around nickel, chromium, and cadmium may play a role in the development of the disease.
13. Prior Chemotherapy or Radiation: If you had these treatments for other cancers, there might be a slightly elevated risk.
14. HIV Infection: Being HIV positive makes one more susceptible to certain cancers, including small cell carcinoma.
15. Chronic Inflammatory Diseases: Conditions causing prolonged inflammation can increase risk.
16. Diet and Nutrition: Some believe a diet low in fruits and veggies might up your chances, though research is ongoing.
17. Outdoor Air Toxins: Chemicals in outdoor air, like those from factories, may pose a risk.
18. Indoor Air Toxins: Household products, like certain paints, can release harmful chemicals.
19. Genetic Mutations: Some gene changes can make you more prone to the disease.
20. Scarring in the Lungs: Past infections or injuries can leave scars, which might increase the risk.
21. History of Other Cancers: If you’ve had another type of cancer before, this may elevate your risk.
22. Certain Viral Infections: Some viruses might play a part in causing the disease.
23. Hormone Replacement Therapy (HRT): Women on HRT for menopausal symptoms might see a slight rise in risk.
24. Recreational Drug Use: Using certain illegal drugs can damage the lungs, upping the risk.
25. Autoimmune Diseases: Diseases where your immune system attacks your body might raise your risk.
26. Socioeconomic Status: Research suggests people in lower socioeconomic groups might be at higher risk, possibly due to lifestyle or environmental exposures.
27. Urban Living: City life exposes you to more pollutants than rural living.
28. Wood Smoke: Constantly inhaling wood smoke, as from a fireplace, might up your chances.
29. Passive Smoking: Even if you don’t smoke, living with a smoker can increase your risk.
30. Lifestyle Factors: A combination of poor diet, lack of exercise, and chronic stress might contribute.
Symptoms
Common symptoms of Small Cell Carcinoma in simple terms, helping you understand and identify potential warning signs.
1. Persistent Cough: A consistent cough that doesn’t go away may signal Small Cell Carcinoma. This cough might worsen over time and may even produce blood.
2. Shortness of Breath: Feeling breathless, especially during physical activities or while lying down, could be a symptom of Small Cell Carcinoma’s impact on lung function.
3. Chest Pain: Experiencing persistent chest discomfort or pain can be indicative of the cancer spreading or pressing against surrounding tissues.
4. Fatigue: Feeling excessively tired, even after ample rest, might result from the body fighting the cancer and the impact of cancer cells on energy levels.
5. Unexplained Weight Loss: Losing a significant amount of weight without changes in diet or exercise could be due to the body diverting energy to combat the cancer.
6. Loss of Appetite: Small Cell Carcinoma can affect your appetite, leading to reduced interest in eating, which in turn contributes to weight loss.
7. Swelling: Swelling in the face, neck, arms, or upper chest may occur when the cancer affects blood vessels or lymph nodes.
8. Hoarseness: Changes in your voice, such as hoarseness or raspiness, might be caused by the cancer impacting the nerves controlling your vocal cords.
9. Difficulty Swallowing: Trouble swallowing, also known as dysphagia, can arise if the cancer obstructs the passage in the throat or esophagus.
10. Persistent Infections: Frequent infections like pneumonia could indicate a weakened immune system, often associated with cancer’s effect on the body’s defenses.
11. Bone Pain: If Small Cell Carcinoma spreads to the bones, it can cause localized pain, making it uncomfortable to move or carry out daily activities.
12. Neurological Symptoms: Symptoms like headaches, weakness, or numbness might emerge if the cancer affects the nervous system.
13. Vision Changes: Blurry vision or other visual disturbances could result from the cancer affecting the optic nerves or other parts of the visual pathway.
14. Skin Changes: Small Cell Carcinoma might cause the skin to become itchy, discolored, or develop lumps, due to the impact of cancer cells on skin cells.
15. Nausea and Vomiting: Feeling nauseous or vomiting might occur as a result of the body’s reaction to the cancer or its treatment.
16. Confusion: Cancer-related complications might lead to confusion, memory problems, or difficulty concentrating.
17. Muscle Weakness: Weakened muscles, often in the arms and legs, can result from the cancer’s impact on nerves that control muscle function.
18. Hormonal Changes: Small Cell Carcinoma can disrupt hormonal balance, leading to issues like sudden mood swings, changes in menstrual cycles, or sexual dysfunction.
19. Excessive Sweating: Unexplained, intense sweating—especially at night—may be linked to the body’s response to cancer.
20. Clubbing of Fingers: Nails becoming rounder and wider at the fingertips, known as clubbing, can occur due to decreased oxygen levels from lung-related complications.
Diagnosis
Here, we’ve prepared a guide explaining diagnostic tests for SCC, broken down in plain English.
