Virginia Cancer Institute wants you to know as much as possible about your condition. This A to Z resource brings you a wealth of knowledge on specific types of cancer.
Cancer is not one disease, but many diseases that occur in different areas of the body. Each type of cancer is characterized by the uncontrolled growth of cells. Under normal conditions, cell growth is carefully controlled by the body. However, these controls can malfunction, resulting in abnormal cell growth and the development of a lump, mass or tumor. Some cancers involving the blood and blood-forming organs do not form tumors but circulate through other tissues, where they grow.
A tumor may be benign (noncancerous) or malignant (cancerous). Cells from cancerous tumors can spread throughout the body. This process, called metastasis, occurs when cancer cells break away from the original tumor and travel through the blood to another area of the body. Common locations of metastasis are the bones, lungs, liver and central nervous system.
The type of cancer refers to the organ or area of the body where the cancer first occurred. Cancer that has metastasized to other areas of the body is named for the part of the body where it originated. For example, if breast cancer has spread to the bones, it is called “metastatic breast cancer,” not bone cancer.
