They leave healthy cells alone and attack only cancer cells, which work differently. Tyrosine kinase inhibitors (TKIs) can basically cure CML, though you have to take them for life. For CLL, medicines called monoclonal antibodies mark cancer cells so your immune system can destroy them. And kinase inhibitors keep CLL cells from growing and dividing.
Can leukemia be a sign of anemia?
There's no telltale sign for leukemia. The symptoms tend to be vague. At first, it may just seem like the flu. Having fewer red blood cells can give you anemia, making you pale, tired, and short of breath. When you're low on healthy white blood cells, you can't fight infections as well. You get sick more often, and the sickness lasts longer. With low platelets, you bruise and bleed more easily.
What are the complications of leukemia?
In either situation, levels of blood components such as red blood cells and platelets can become too low, leading to dangerous complications. Too few red blood cells (anemia) means the blood cannot carry enough oxygen to the body’s tissues. Symptoms of anemia include fatigue, weakness, dizziness, headache, leg cramps, fast heart rate, and pale skin . Platelets are cell fragments necessary for normal blood clotting. Low levels of platelets (thrombocytopenia) can cause abnormal bleeding such as nosebleeds, red spots on the skin, and skin that bruises easily.

What is the disease of the white blood cells?
Leukemia is a disease of the white blood cells. A leukemia patient has an elevated white blood cell count consisting largely of immature and unhealthy white blood cells. Normal bone marrow cells are displaced by increasing numbers of the malignant cells, which results in a lack of blood platelets and regular white blood cells needed to clot blood and fight infection.
How does blood help the body?
Blood also enables other cells and substances to be transported between tissues and organs, transfers heat to the skin, and acts as a buffer to regulate pH. About five liters of blood circulate in an average adult. Blood is created solely by the marrow inside bones.

Why is leukemia staged differently than other cancers?
Leukemia is staged differently than other cancers because it shows up in the blood instead of with tumors. Higher survival rates are associated with lower or earlier stages, while more advanced stages generally mean a lower survival rate.
What is the stage of CLL?
Sometimes doctors will use a different system to stage CLL. The Binet staging system uses the number of tissue groups affected by lymphocytes and the presence of anemia to stage CLL. There are three stages in the Binet system: Binet stage A. In stage A, less than three areas of tissue are affected.

This test will also help doctors determine what type of leukemia you have and if it has spread. Organ biopsy. You might need a biopsy of an organ, such as your liver, if your doctor suspects the cancer has spread.
Which subtypes have the lowest survival rate?
Subtypes M3, M4, and M5 have average AML survival rates. Low survival rate. People with subtypes M0, M6, and M7 have a worse prognosis because these subtypes have a lower survival rate than the average for all AML subtypes. FAB subtypes are still widely used to classify AML.
Watch and wait
If you have a chronic type of leukemia and are relatively healthy, your doctor may recommend watching and waiting before beginning treatment. Because some treatments may be harmful to older adults, this helps make sure you’re not treated until you need to be.
Chemotherapy
Chemotherapy is a common treatment for leukemia in people of all ages. If you’re otherwise healthy and have the necessary social support, your doctor may recommend intensive chemotherapy, which has a higher chance of curing your leukemia.
Stem cell transplant
Stem cell transplants may not be offered to older people often, but they can be very successful in preventing leukemia relapse. A relapse is when your leukemia returns after treatment has ended. You need to be generally healthy (besides the leukemia) to have a stem cell transplant.
Medications
There are several types of medications available for treating leukemia, including immunotherapies and kinase inhibitors. Immunotherapies help your immune system kill cancer cells, while kinase inhibitors help stop the cancer from growing.
Acute leukemias
For people ages 70 years and older, the median overall survival rate for ALL is 4 months, and the survival rate for AML is 6 to 12 months.
Chronic leukemias
For chronic leukemias, treatment is usually used to control the spread of cancer and manage your symptoms. It’s generally not expected to cure the leukemia, although you can live for many years with chronic leukemia. If you go into remission after treatment, a stem cell transplant can further increase your survival rate.
