The most common type of cancer is called carcinoma, which is a cancerous tumor that forms in the tissues of an organ or tissue. It can be found anywhere in the body, but it is usually found in the lungs, breast, skin, stomach, prostate, colon, rectum, or cervix. Carcinoma affects all organs and tissues, causing them to grow abnormally and divide uncontrollably. This can lead to pain, swelling, and other symptoms depending on where the cancer is located.
