Leukemia is a cancer that affects blood cells in the bone marrow. It starts when a single cell mutates and develops abnormally. There are many types of leukemia that affect both children and adults. Treatment depends on the specific type of leukemia diagnosed as well as other factors like age and health. Image segmentation techniques using microscopic images of blood samples can help detect leukemia at early stages to improve survival rates. Survival rates vary by type of leukemia, with acute myeloid leukemia having a 5-year relative survival rate of around 30% for all ages.
