Cancer

Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells in the body. These cells can invade and destroy surrounding tissues and organs. Cancer can arise in almost any part of the body, and it is typically classified by the type of cell or organ it originates from, such as breast cancer, lung cancer, or leukemia.

Cancer development often involves genetic mutations that disrupt normal cellular processes, leading to unchecked cell division. Various risk factors contribute to the likelihood of developing cancer, including genetic predisposition, environmental exposures, lifestyle factors (such as smoking and diet), and infectious agents.

The diagnosis of cancer usually involves imaging tests, biopsies, and laboratory tests. Treatment options vary depending on the type and stage of cancer and may include surgery, chemotherapy, radiation therapy, immunotherapy, or targeted therapy.

Early detection and treatment are crucial for improving outcomes in cancer patients. Research continues to advance our understanding of cancer, leading to improved therapies and potential cures.
