Afinitor is also used to treat a type of benign kidney tumor called renal angiomyolipoma and a type of benign brain tumor called subependymal giant cell astrocytoma in patients who have tuberous sclerosis. Afinitor blocks a protein involved in cell division, which may help keep abnormal cells, including cancer cells, from growing. It may also prevent the growth of new blood vessels that tumors need to grow. Afinitor is a type of kinase inhibitor and a type of angiogenesis inhibitor.
