Cancer: Types, Causes, Treatment & Prevention

Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. These cells can form tumors and invade nearby tissues and organs, causing damage and potentially spreading to other parts of the body. There are many types of cancer, including breast cancer, lung cancer, prostate cancer, and colon cancer, among others. Causes of cancer can include genetics, environmental factors, lifestyle habits, and exposure to certain chemicals or radiation. Treatment options can include surgery, chemotherapy, radiation therapy, targeted therapy, and immunotherapy, depending on the type and stage of cancer. Prevention measures such as maintaining a healthy lifestyle, avoiding tobacco and excessive alcohol consumption, and getting regular screenings can also help reduce the risk of developing cancer.
