leukemia cells travel through the body. The symptoms of leukemia depend on the number of leukemia cells and where these cells collect in the body.
chronic leukemia may not have symptoms. The doctor may find the disease during a routine blood test.
People with acute leukemia usually go to their doctor because they feel sick. If the brain is affected, they may have headaches, vomiting, confusion, loss of muscle control, or seizures. Leukemia also can affect other parts of the body such as the digestive tract, kidneys, lungs, heart, or testes.
Common symptoms of chronic or acute leukemia may include:
Swollen lymph nodes that usually don't hurt (especially lymph nodes in the neck or armpit)
Most often, these symptoms are not due to cancer. An infection or other health problems may also cause these symptoms.
Diagnosis
Physical exam: Your doctor checks for swollen lymph nodes, spleen, or liver.
Blood tests: The lab does a complete blood count to check the number of white blood cells, red blood cells, and platelets. Leukemia causes a very high level of white blood cells. It may also cause low levels of platelets and hemoglobin, which is found inside red blood cells.
Biopsy: Your doctor removes tissue to look for cancer cells. A biopsy is the only sure way to know whether leukemia cells are in your bone marrow. Before the sample is taken, local anesthesia is used to numb the area. This helps reduce the pain. Your doctor removes some bone marrow from your hipbone or another large bone. A pathologist uses a microscope to check the tissue for leukemia cells.
