Immune system kills spontaneous blood cancer cells every day

Each and every one of us has spontaneous mutations in our immune B cells that occur as a result of their normal function.

If cancerous B cells go on to form tumors they develop into B cell lymphomas, also known as non-Hodgkin's lymphomas. B cells, a type of white blood cell, undergo spontaneous changes that could lead to cancer if the immune system does not carry out regular checks and kill them before they form tumors.

The researchers found T cells of the immune system carry out regular checks to find cancerous and pre-cancerous B cells.
