Many chemotherapy drugs work on a cellular level by killing cancer cells to prevent the cancer from spreading. However, when these drugs kill the cancer cells they are also interfering
with the ability of healthy cells to reproduce.
One of the side effects that can occur while undergoing chemotherapy treatment is low platelet counts, if your platelet counts are low, excess bleeding can occur which in turn could increase the risk of one type of stroke (hemorrhagic).
In addition, some cancer tumors can contribute to an increase risk for strokes, for example a tumor that compresses or occludes cerebral vessels, could increase the risk for an ischemic stroke.
