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.
CLL/SLL is the most common adult leukemia in Western countries, accounting for 1.2% of the new cancers diagnosed each year in the United States. It usually occurs in older adults (median age at diagnosis 70) and follows an indolent course over many years. [11] About 1-10% of CLL/SLLs develop a Richter's transformation at a rate of 0.5–1% per ...

T-PLL is a very rare leukemia, primarily affecting adults over the age of 30. It represents 2% of all small lymphocytic leukemias in adults. [2] Other names include T-cell chronic lymphocytic leukemia, "knobby" type of T-cell leukemia, and T-prolymphocytic leukemia/T-cell lymphocytic leukemia. [1]
Adult T-cell leukemia/lymphoma (ATL or ATLL) is a rare cancer of the immune system's T-cells [1] [2] [3] caused by human T cell leukemia/lymphotropic virus type 1 (). [4] All ATL cells contain integrated HTLV-1 provirus further supporting that causal role of the virus in the cause of the neoplasm. [4]

MDS most often develops without an identifiable cause. Risk factors include exposure to an agent known to cause DNA damage, such as radiation, benzene, and certain chemotherapies; other risk factors have been inconsistently reported. Proving a connection between a suspected exposure and the development of MDS can be difficult, but the presence ...
FL is the most prevalent form of indolent lymphoma, accounting for 70% of indolent cases and 20–30% of all non-Hodgkin lymphoma cases, with a yearly incidence of 1.6 to 3.1 per 100,000. [ 13 ] [ 15 ] It is most frequently diagnosed among people in their 50s and 60s, and is more common among white populations than black or Asian populations.
