When we hear the word "cancer," we all get a little scared, right? When we hear the word "blood cancer," we can feel even more scared. But it's very important to be aware of what exactly it is, why it develops, what are the symptoms, and whether there are treatments. Then you can face this situation without unnecessary fear. So, today we will talk about this blood cancer simply, in a way that you can understand.
What is Blood Cancer? What happens in our body?
Simply put, blood cancer is a disease that affects the blood-forming cells in our body and the way those cells work. Most of these blood cancers start in our bone marrow. Bone marrow is a soft, sponge-like substance inside our bones. This bone marrow is where our body makes stem cells. These stem cells later become blood cells like this:
- Red Blood Cells: These are what carry oxygen throughout our bodies. Think of them as little trucks that carry life to every part of our bodies.
- White Blood Cells: These are like soldiers that fight diseases and germs that enter our bodies.
- Platelets: These help stop bleeding when there is a wound.
Now, when a blood cancer develops, for some reason, the process of making these blood cells goes haywire. The cancer cells that form then can't do the job that normal blood cells do. Instead, these abnormal cancer cells divide rapidly and out of control, crowding out the good blood cells and crippling the entire system. It's like weeds that grow and cover up good plants.
Blood cancer is a serious disease, that's true. But the good news is that many people are now recovering from blood cancer, or living successfully with the disease.
Are there types of blood cancer? What are they?
Yes, there are three main types of blood cancer. Each type has several subtypes.
1. Leukemia: This is the most common type of blood cancer, especially in childhood. Leukemia cells start in the bone marrow. From there, they can spread to the blood. Most often, these are immature white blood cells.
2. Lymphoma: This is a cancer that develops in our lymphatic system. Lymphoma cells start from a type of white blood cell called lymphocytes. These cancer cells can form tumors in places like our lymph nodes. Hodgkin Lymphoma and Non-Hodgkin Lymphoma are the two main subtypes.
3. Myeloma: This is also a cancer that starts in the bone marrow. It affects a type of white blood cell called plasma cells. Multiple Myeloma is the most common subtype.
In addition to these main types, there are also some less common types of blood cancer:
- Myeloproliferative Neoplasms (MPN): This cancer causes your bone marrow to produce more white blood cells, red blood cells, or platelets than necessary.
- Myelodysplastic Syndromes (MDS): In this condition, your bone marrow makes abnormal blood cells. Sometimes these blood cells don't mature properly, which is why they're abnormal. These immature cells are also called blasts.
What are the symptoms of this disease?
The symptoms of blood cancer can vary depending on the type of cancer, but there are some common symptoms to look out for:
- Feeling very tired (Fatigue): Not just tiredness, but extreme tiredness that doesn't go away no matter how much sleep you get.
- Shortness of breath: Even doing a small task can make you feel short of breath.
- Swollen lymph nodes: Painless swelling in places like the neck, armpits, and groin.
- Frequent infections: Infections occur more often because the body's disease-fighting cells are weakened.
In addition to this, there may be other symptoms:
- Body aches, especially bone pain.
- Drenching night sweats: To the point where the bed sheets get wet.
- Enlarged liver or spleen.
- Joint pain.
- Persistent fever.
- Unexplained weight loss.
- Unusual bruising or bleeding, bleeding from even a small bruise, small red spots (petechiae) or purple spots (purpura) on the skin.
The important thing is, don't be afraid that you have cancer just because you have one or more of these symptoms. These can also be symptoms of other common illnesses. But if these symptoms persist for more than a few weeks, it's definitely wise to see a doctor and get checked out.
Why does this blood cancer develop? What is the cause?
The main cause of blood cancer is changes (mutations) in the `DNA` of blood cells. Simply put, `(DNA)` is like the "control center" that gives instructions to our cells. Everything that determines when a blood cell should grow, when it should divide, and when it should die is determined by the instructions given by this `(DNA)`.
So, if the wrong instructions are written in this `(DNA)`, that is, if a `(mutation)` occurs, abnormal blood cells start to form in our body. These abnormal cells start to divide faster and more uncontrollably than normal cells. When that happens, the good, normal blood cells are gradually overwhelmed, and the system is filled with a lot of abnormal cells.
Eventually, the number of normal cells produced by the bone marrow decreases. This means that there are not enough good cells that do essential work for the body.
What are the risk factors for developing blood cancer?
There are some factors that increase the risk of developing blood cancer. They are:
- Age: The risk increases with age.
- Gender: Men are more likely to develop blood cancer.
- Smoking: People who smoke or are exposed to secondhand smoke are at higher risk.
- Exposure to toxic chemicals: Long-term exposure to chemicals like `(Benzene)` and `(Formaldehyde)` can increase the risk. This risk is higher for people who work in places like factories.
- Previous cancer treatment: If you have previously received cancer treatments such as chemotherapy or radiation therapy, your risk of developing blood cancer may be slightly increased.
- Family history: Some types of blood cancer run in families. However, not everyone who develops blood cancer has a family history of the disease.
- Certain medical conditions: People with certain autoimmune diseases (diseases that attack the body's own cells), chronic inflammation, and certain genetic diseases are at increased risk of blood cancer.
Is there anything we can do to reduce this risk?
To be honest, blood cancer is not a completely preventable disease. Even a healthy person with no risk factors can develop blood cancer. However, by staying away from some risk factors, such as avoiding smoking, the risk can be reduced to some extent.
How do doctors diagnose this disease? (Diagnosis)
If you have these symptoms, a doctor will first ask you about your symptoms, your medical history, and whether anyone in your family has had these conditions. Then they will do a complete physical exam. Depending on the type of cancer the doctor suspects, they may need to do several different tests.
- Blood Tests:
- Complete Blood Count (CBC): This checks for low or high levels of red cells, white cells, and platelets in the blood.
- `Blood Chemistry Test`: This checks for certain proteins and enzymes in the blood. These can be signs of blood cancer.
- Imaging tests: These can look for signs of cancer inside the body. Examples of these tests include CT scans, MRI scans, and PET scans.
- Bone Marrow Biopsy: Your doctor will take a small sample of your bone marrow and examine it. This will help to see how many abnormal cancer cells there are compared to normal cells, and whether there are any changes in the DNA that could be cancer-causing.
What are the treatments for blood cancers?
Fortunately, there are now many advanced treatments for blood cancer. Here are some of the main treatments:
- Chemotherapy: This is the main treatment for blood cancers. It works by destroying cancer cells and controlling the spread of the disease, or even eliminating it completely. Different types of chemotherapy drugs are used for different types of blood cancers.
- Radiation Therapy: This treatment uses high-energy rays to damage the DNA of abnormal cells and stop them from dividing. Sometimes this treatment is also given to reduce symptoms (Palliative Care). It is often given in combination with other treatments.
- Immunotherapy: This works by strengthening your body's own immune system to help it fight cancer. Monoclonal Antibodies and CAR T-cell Therapy are popular treatments used for this.
- Targeted Therapy: These drugs are designed to target and attack specific weaknesses in cancer cells caused by genetic changes.
- Stem Cell Transplant:
- Autologous Stem Cell Transplant: In this, doctors collect and store stem cells from your own bone marrow before giving you high-dose chemotherapy. After the chemotherapy kills the cancer cells, the healthy stem cells are returned to your body. They then produce healthy blood cells.
- Allogeneic Stem Cell Transplant: Sometimes, it is necessary to replace damaged bone marrow with healthy bone marrow. In this case, doctors find a bone marrow donor who is a match for you and use their cells to replace your damaged cells.
When do you want to see the doctor again?
Your doctor will tell you what symptoms or signs you should look out for after treatment. All cancer treatments can cause side effects, some of which can be serious. Your doctor will explain how you can manage some of these side effects at home. He or she will also tell you when you need to make a follow-up appointment or seek emergency treatment.
Can blood cancer be completely cured?
Yes! In most cases, the goal of blood cancer treatment is to cure the disease completely. That means the cancer is completely gone and will not come back. Although sometimes a complete cure is not possible, advanced treatments now allow some types of blood cancer to go into a state called ``remission.' ' ``Remission'' means that treatment has reduced the cancer to the point where it is no longer visible and cannot be detected by tests. That means you can live a normal, healthy life with the disease.
What are the survival rates for blood cancer?
Survival rates vary depending on the type of cancer, but most people can expect to live as long as someone without blood cancer.
Remember, no one can predict exactly how long someone will live. For example, some types of blood cancer are more deadly than others. Also, these survival rates don't take into account the success of the latest treatments. In fact, the number of people surviving lymphoma has doubled in the past 40 years. And the five-year survival rate for people surviving leukemia has quadrupled in the past 40 years! More and more people are surviving blood cancers every day.
What can I do to help me feel better?
Blood cancer and its treatment can affect your overall health. Here are some things that can help you stay well:
- Eat a nutritious, balanced diet. Blood cancer and its treatments can cause loss of appetite. If you have difficulty eating, talk to a dietitian about how you can get the nutrition you need.
- Stay as active as possible. Exercise is important, but ask your doctor what level of exercise you can safely do.
- Make rest a priority. Listen to your body. Rest whenever you need to, not just when you feel tired.
- Protect yourself from infections. Ask your doctor about ways to prevent getting sick (e.g., avoiding crowded places, washing your hands frequently).
- Take care of your mental health. During difficult times like these, talking to a therapist or joining a support group can be a great source of strength. It can also help you cope with life after cancer.
Because of new treatments, more people are now living with leukemia than ever before. And many people who have been diagnosed are in remission. This is great news. But leukemia is still a serious disease. So it's important to take advantage of all the help and resources available to you. Understand all of your treatment options. Talk to your doctor about how your diagnosis and treatment will affect your future.
