Though no tests have been discovered to detect all cancers, there are tests to pick up some. A pap test is used to search for cancer of the uterine cervix. Mammograms are used to detect breast cancer and blood and stool tests are used to find colon cancer. There are many other tests besides these to test for all different types of cancer. There are really three different types of cancer.
Surgical removal is the first, it is the most basic treatment.
It is used to remove the cancerous legions in the body. The second is radiation therapy, which uses radiation to try and kill the tumor. One of the main problems with that is not only does it kill cancerous tissue, it also kills healthy ones. The third way to treat cancer is chemotherapy, which is treatment by chemical agents.
