Acute Lymphocytic Leukemia (ALL)
With ALL, abnormal white blood cells accumulate in bone marrow and replace the healthy cells necessary to produce functioning lymphocytes with cancerous cells that cannot mature properly.
These abnormal cells are carried throughout the body in the bloodstream, which makes them prone to infecting other organs like the brain, lymph nodes, liver, and testes. This form of leukemia can happen at any age, but is found most commonly in people under 15 or over 45 years.
