Cancer

Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells in the body. These abnormal cells can form tumors, invade nearby tissues, and spread to other parts of the body through the bloodstream or lymphatic system.

Cancer can occur in any part of the body and can affect people of all ages, although the risk of developing cancer increases with age. Some common types of cancer include breast cancer, lung cancer, prostate cancer, colorectal cancer, and skin cancer.

The causes of cancer are complex and multifactorial, and may include genetic, environmental, and lifestyle factors. Certain genetic mutations or inherited conditions can increase the risk of developing certain types of cancer, while exposure to environmental factors such as tobacco smoke, radiation, and certain chemicals can also increase the risk.
