Previously Untreated CLL/SLL

What is cll/sll?

Actor portrayal.

CLL and SLL are types of cancer that affect your blood.

CLL (chronic lymphocytic leukemia) is a usually slow-growing blood cancer that affects B cells, also called B lymphocytes. B cells are a type of white blood cell that helps fight infection.

SLL (small lymphocytic lymphoma) is closely related to CLL. However, SLL cancer cells are mostly found in the lymph nodes rather than in the blood and bone marrow.

In people with CLL, normal B cells mutate into abnormal, unhealthy cells.

Healthy cells become cancerous

In people with CLL, normal B cells mutate into abnormal, unhealthy cells.

Abnormal cancer cells multiply more quickly than healthy cells and may live longer than they're supposed to. This makes it more difficult for healthy cells to do their job.

Abnormal B cells start to build up in the bone marrow, lymph nodes, and blood, and may also involve other organs, such as the liver and spleen.
