Cancer is a disease that occurs when some of the body’s cells grow overwhelmingly and spread to other parts of the body. There are over 100 types of cancer. Cancers are usually named for the organs or tissues where cancer formed or is labeled by the type of cell that formed them, for example, epithelial cell or squamous cell. There you can search for different cancers based on where it is found in the body. Because the human body is made up of trillions of cells cancer can grow almost anywhere in the body. In a normal situation, the cells grow and multiply in a process called cell division. As cells grow old or become damaged, they die, and new cells grow in their place. When this process is interrupted and damaged or abnormal cells grow and multiply causing lumps that turn into lumps or tumors. These tumors can be malignant (cancerous) or benign (non-cancerous). For more information on the different types of cancer, you can refer to the NCI’s (National Cancer Institute) website.
