TYPES OF CANCER




Cancer can be of numerous types. There are almost more than 200 types of cancer detected so far. Normally the cancer is specifically named for the organ or tissues where that cancer is formed. It can be understand by the example that a Lung cancer is where the cancer is started in the cells of lungs. Likewise we call a cancer Brain cancer when it starts from the cells of brain. We can also describe a cancer by the type of cell responsible of forming them. An epithelial cell or a squamous cell is one such examples.

Types of cancer which are formed by some specific cells are- Carcinoma, Sarcoma, Leukemia, Melanoma, Lymphoma and myeloma. There are also Central nervous system cancers, which are the cancers that begin in the tissues of the brain and spinal cord (brain and spinal cord tumors)

There are also some types of cancers which are considered as metastatic cancers. In metastatic cancer, cancer cells spread to other normal cells. It can spread to nearby tissues, lymph nodes or organs and even to a distant part of the body. This process of spreading of cancerous cells to other parts of the body is called metastasis. Such cancers are named the same as primary cancer. For example, if a woman is suffering from breast cancer and it has spread to her lungs, then she would be said to have metastatic breast cancer, not the lung cancer, and would be given the treatment for stage IV breast cancer. In metastatic cancer, sometimes it is difficult for the doctors also to decide the origin place of such cancer.
