Radiobiology
Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells in the body. These rogue cells can form tumors, invade nearby tissues, and metastasize to distant parts of the body, often disrupting normal bodily functions. Cancer arises from genetic mutations that can result from various factors, including environmental influences like free radicals and disruptions in the cell cycle, which include checkpoints that normally prevent such unchecked growth.
