Cancer
Cancer is a broad term used to describe 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 metastasize to other parts of the body.
There are more than 100 different types of cancer, each with its own set of characteristics and treatment options. Some of the most common types of cancer include breast cancer, lung cancer, prostate cancer, and colorectal cancer.
The exact causes of cancer are often complex and can involve a combination of genetic, environmental, and lifestyle factors. Risk factors for developing cancer can include smoking, excessive alcohol consumption, unhealthy diet, lack of physical activity, exposure to radiation or carcinogens, and family history of the disease.
Cancer diagnosis typically involves a combination of imaging tests, laboratory tests, and biopsies to confirm the presence of cancer cells. Treatment options for cancer vary depending on the type and stage of the disease but may include surgery, chemotherapy, radiation therapy, immunotherapy, targeted therapy, hormone therapy, or a combination of these approaches.
