What is "cancer"?

Cancer is a disease where abnormal cells grow and spread uncontrollably, often forming lumps or tumors in the body. These abnormal cells can disturb the normal functioning of organs and tissues, leading to a range of symptoms depending on the type and location of the cancer. Common symptoms can include unexplained weight loss, lasting fatigue, changes in bowel or bladder habits, and unusual lumps or growths. There are many different types of cancer, each with its own set of risk factors, causes, and treatment options. Treatment for cancer may include surgery, chemotherapy, radiation therapy, immunotherapy, or a combination of these approaches, depending on the specific type and stage of the cancer. Early detection and immediate treatment are important for improving outcomes and increasing the chances of survival.
