Breast cancer has some symptoms. For example: nipple discharge or tenderness; or redness, swelling, or scaling of the skin of the breast, nipple, or areola. The other symptoms are arraigning in the shape or size of the breast or generate a lump or thickening in or close to the breast. These diseases are diagnosed with some method. There are four methods for diagnosed breast cancer like ultrasonography, mammography, biopsy, and a clinical breast test. For example, ultrasonography uses high frequency sound waves to establish whether a lump is not cancer or may not be cancer. Mammography uses X-rays to get hold of a picture of the breast and any lumps that may be in attendance. And clinical test used to position obvious lumps in the breast.
