What immune problems make beating MCC more difficult?
People with severe defects in “T lymphocytes” (key cells of the immune system) have a 10-30 times greater chance of developing MCC and twice the chance of losing the battle with MCC compared to people with a normal immune system. The conditions that cause such severe T lymphocyte defects include HIV (AIDS), taking immune suppressive drugs after solid organ transplantation, and certain immune cancers such as chronic lymphocytic leukemia. In contrast, suffering from more “colds” than average will not importantly affect your ability to fight MCC.
