Chronic lymphocytic leukemia (CLL) is a type of cancer that affects the blood and bone marrow. [8] [9] In CLL, the bone marrow makes too many lymphocytes, which are a type of white blood cell. [8] [9] In patients with CLL, B cell lymphocytes can begin to collect in their blood, spleen, lymph nodes, and bone marrow.
Radiation can cause cancer in most parts of the body, in all animals, and at any age, although radiation-induced solid tumors usually take 10–15 years, and can take up to 40 years, to become clinically manifest, and radiation-induced leukemias typically require 2–9 years to appear.
Overall, leukemia is the eleventh most common cancer in the UK (around 8,600 people were diagnosed with the disease in 2011), and it is the ninth most common cause of cancer death (around 4,800 people died in 2012). [87]
The basic cause of sporadic (non-familial) cancers is DNA damage and genomic instability. [1] [2] A minority of cancers are due to inherited genetic mutations. [3] Most cancers are related to environmental, lifestyle, or behavioral exposures. [4] Cancer is generally not contagious in humans, though it can be caused by oncoviruses and cancer ...

Five years after receiving a life-changing stem cell transplant, a 68-year-old man says he’s “extremely grateful” to be essentially cured of acute myelogenous leukemia and in HIV remission.
Acute lymphoblastic leukemia affected about 876,000 people globally in 2015 and resulted in about 111,000 deaths. [14] [10] It occurs most commonly in children, particularly those between the ages of two and five. [15] [4] In the United States it is the most common cause of cancer and death from cancer among children. [2]
Maintenance is a lower intensity chemotherapy regimen that used to kill any more remaining cells in the bone marrow that could regrow into cancer cells and cause the leukemia to come back. It lasts for 18–30 months. [3] [5] Immunotherapy, radiation therapy, stem cell transplant, and targeted therapies may also be used in the treatment of ALL.
