What for biopsy is done?

During needle biopsy, a long, thin needle is inserted through the skin and into the suspicious area. Cells are removed and analyzed to see if they are cancerous.

Can a doctor tell if a tumor is cancerous by looking at it?

Cancer is nearly always diagnosed by an expert who has looked at cell or tissue samples under a microscope. In some cases, tests done on the cells’ proteins, DNA, and RNA can help tell doctors if there’s cancer. These test results are very important when choosing the best treatment options.
