Leukemia occurs when blood cells acquire mutations to their DNA. Certain abnormalities cause the blood cells to grow and divide more rapidly and to continue living when normal cells would die. Over time, the abnormal blood cells crowd out the heathy blood cells in the bone marrow, leading to fewer healthy white blood cells, red blood cells, and platelets.
Types of Leukemia
Leukemia is classified by how fast the leukemia progresses and the type of white blood cell affected.
Classification of Leukemia:
- Acute leukemia indicates that the disease progresses rapidly and creates immature blood cells that do not function normally.
- Chronic leukemia indicates the disease progresses slowly and created more mature blood cells that can function normally for a period of time.
- Lymphocytic Leukemia affects the lymphoid cells (lymphocytes), which form lymphoid tissue.
- Myelogenous leukemia affects the myeloid cells, which give rise to red blood cells, white blood cells, and platelet-producing cells.
Major types of leukemia:
- Acute lymphocytic leukemia (ALL)
- Acute myelogenous leukemia (AML)
- Chronic lymphocytic leukemia (CLL)
- Chronic myelogenous leukemia (CML)
Symptoms of Leukemia:
- Persistent fatigue
- Severe or frequent infections
- Easy bruising or bleeding
- Unintentional weight loss
- Tiny red spots in skin (petechiae)
- Night sweats
- Bone pain or tenderness
- Swollen lymph nodes
- Enlarged liver or spleen
