Do you have a painless lump on your neck, armpit, or groin? Or are you bothered by sweating so much that your sheets get wet at night? These can be normal, but sometimes they can be symptoms of a type of blood cancer called B-Cell Lymphoma. Don't be scared when you hear this name. It's not hard to understand. Let's talk about it simply, clearly, and in a way that you can understand.
Simply put, what is B-Cell Lymphoma?
B-cell lymphoma is a type of blood cancer that develops in our lymphatic system. Okay, now let's simplify this even further.
Our blood contains a type of cell called white blood cells. These are like our body's own army. These cells protect us by fighting germs that cause disease. One type of white blood cell is called lymphocytes. Among these lymphocytes, there is a special type called B-cells. They are the main part of our body's defense army.
When B-cell lymphoma develops, something goes wrong with these B-cells, causing them to divide and multiply uncontrollably, becoming cancerous cells and forming tumors.
Our lymphatic system is a network of vessels, lymph nodes, and tissues that are spread throughout our body. It's like a second circulatory system in our body. This is why B-cell lymphoma can develop anywhere in the body. That's why the symptoms vary from person to person.
Importantly, B-cell lymphoma is the most common type of non-Hodgkin lymphoma. In most cases, there are effective treatments. Some types can be cured completely. In others, symptoms can be reduced and the cancer can be kept in remission.
These lymphomas are mainly divided into two types:
When your doctor talks about this disease, he or she may use two words: "aggressive" and "indolent." This is what they mean:
- Aggressive (rapidly spreading) type: This type grows more quickly and can spread (metastasize) to other organs outside the body through the lymphatic system.
- Indolent (slow-growing) type: This type grows very slowly and may not show symptoms for years.
To make it easier to understand, let's look at these types in a table like this.
| Type of lymphoma | Simple description and examples |
|---|---|
| Aggressive (spreads rapidly) | These grow quickly. Examples:
|
| Indolent (slow-growing) | These can be asymptomatic for months or years. Examples:
|
What are the symptoms of B-cell lymphoma?
Sometimes you can have B-cell lymphoma without any symptoms. Especially in the slow-growing types, it is often discovered incidentally during tests for another disease. However, you should be concerned if you experience the following symptoms:
| Symptom | What does this mean? |
|---|---|
| Swollen lymph nodes | Painless lumps in the neck, armpits, and groin. This is the most common symptom. |
| Excessive sweating at night | Sweating as soon as your sleep clothes and bed sheets get wet. |
| Unexplained fever | A fever (over 38 Celsius / 100.4 Fahrenheit) that lasts for more than two days or is persistent. |
| Weight loss for no reason | Sudden weight loss without dieting or exercise. |
| Constant fatigue | Feeling weak no matter how much rest you get. The main reason for this may be that the cancer cells in the bone marrow reduce the production of red blood cells, causing anemia. |
| Stomach pain | Some types can cause persistent stomach pain because they start in the stomach. |
| Appetite | If the spleen is swollen, it can push on the intestines and make you feel full even after eating a little. |
| Itching (Pruritus) or skin changes | Some types start in the skin and can cause rashes, boils, and lumps. Or if the liver is affected, the skin can become itchy. |
Remember, having one or more of these symptoms does not mean you have lymphoma. A common cold can also cause a sore throat. But if these symptoms persist or worsen, be sure to see your doctor for advice.
Why does something like this happen?
It's hard to pinpoint a single cause for this. The main thing is that our B-cells become cancerous due to a random genetic change (mutation) that occurs when they divide. However, research has found that certain factors may slightly increase the risk of developing this.
- Some autoimmune diseases: For example, people with diseases like rheumatoid arthritis and Sjörgren's syndrome.
- Some viral infections: Exposure to viruses such as HIV (human immunodeficiency virus), Epstein-Barr virus.
- Family history: If someone in the family has had cancer such as Hodgkin lymphoma.
- Obesity: Excessive body weight is also a risk factor.
How do you find this, Doctor?
When you go to the doctor, he will ask about your symptoms and your medical history. Then he will do a physical exam and check your lymph nodes, liver, and spleen for swelling. If there is any doubt, he will refer you to a hematologist-oncologist. These tests can be done to confirm the diagnosis.
Blood tests
- Complete blood count (CBC): Measures the types and amounts of cells in the blood.
- Comprehensive metabolic panel (CMP): Checks the function of organs such as the liver and kidneys.
- Lactate dehydrogenase (LDH): Elevated levels of this can be a sign of lymphoma.
Imaging tests
- CT scans, PET scans, and ultrasound scans: These can check the condition of lymph nodes and organs inside the body.
Biopsy
This is the only way to 100% confirm the disease.
This involves taking a small sample of a swollen lymph node or suspicious tissue and examining it under a microscope. This can help determine the exact type of lymphoma.
- Excisional or incisional biopsy: Surgical removal of all or part of a lymph node.
- Fine-needle aspiration (FNA): Obtaining a small amount of cells using a thin needle.
- Bone marrow biopsy: Taking a small sample of bone marrow for examination.
What are the treatments?
There is no one-size-fits-all treatment for this. The treatment you receive will depend on factors such as the type of lymphoma you have, how far the disease has spread, and your overall health. Your medical team will choose the treatment plan that is best for you and has the fewest side effects.
The main treatment methods are:
- Chemotherapy: Giving drugs that kill cancer cells.
- Immunotherapy: Stimulating your own immune system to fight cancer cells.
- Radiation therapy: Destroying cancer cells using high-energy rays.
- Targeted therapy: Giving drugs that target and attack only cancer cells. For example: `(monoclonal antibody therapy)`.
- Watchful waiting / active surveillance: For slow-growing types, your condition is monitored continuously, without starting treatment immediately if you have no symptoms. Treatment is only started if symptoms develop.
Side effects of treatment
All treatments can have side effects. Things like stomach upset, diarrhea, fatigue, nausea, and vomiting are common. Don't be afraid of these. Talk to your doctor about them openly. There are medications to help manage the side effects.
When to see the doctor and when to go to the ETU
You will need to see your doctor regularly throughout your treatment. After treatment is over, you will be checked on a regular schedule to see if the disease has returned.
However, in such a case , go to the hospital's Emergency Treatment Unit (ETU) immediately:
- If your fever is higher than 38 Celsius (100.4 Fahrenheit) and does not go down, this is because the treatment may weaken your immune system and lead to infections.
- If the side effects of the treatment are too severe to be controlled with the medication prescribed by the doctor.
Take-Home Message
- B-cell lymphoma is a type of blood cancer that begins in the B-cells of our immune system.
- The main symptoms are painless lumps in the neck, armpits, or groin, excessive sweating at night, constant fatigue, and unexplained weight loss.
- If these symptoms persist, don't ignore them and definitely see a doctor.
- There are many effective treatments for this disease today, so don't give up hope once you've been diagnosed.
- You don't have to go through this journey alone. Get support from your medical team, family, and friends. Your mental health is just as important as your physical health.
