Cancer (general)

Cancer is a disease where some cells in the body grow uncontrollably, forming abnormal masses called tumors. These cells can invade nearby tissues and sometimes spread through the blood or lymphatic system to other parts of the body in a process called metastasis. Cancer arises when genetic mutations disrupt normal cell growth and division. Factors such as genetic predisposition, environmental exposures, and lifestyle can increase risk. Treatment options include surgery, radiation, chemotherapy, and targeted therapies, aiming to remove or destroy cancer cells. Early detection and advances in medicine improve outcomes, but cancer remains a complex disease requiring personalized approaches.
