Cancer is a disease caused by the abnormal growth of cells in the body. It can start when a cell has a genetic mutation, which causes it to proliferate uncontrollably. This can happen in a variety of ways, such as exposure to certain carcinogenic chemicals or radiation, or due to a viral or bacterial infection.
When cancer begins, it is typically localized to one area of the body. However, if it is not caught early, it can spread to other areas of the body through the bloodstream or lymphatic system.
The most common symptoms of cancer include unexplained weight loss, fatigue, persistent pain, and lumps or swelling. Other symptoms may include changes in appetite, changes in bowel habits, and bleeding or discharge from any part of the body. If you experience any of these symptoms, it is important to seek medical attention immediately as they may be signs of cancer.
Your doctor will likely order a variety of tests, such as a biopsy, imaging tests, and blood tests, to diagnose cancer. They may also recommend treatments such as surgery, chemotherapy, or radiation to help treat the disease.
Cancer is a serious disease, and it is important to be aware of the signs and symptoms so that you can get treatment early. If you experience any of the symptoms mentioned above, be sure to contact your doctor right away.
