How to know i have breast cancer?

Mass: A dominant lump in the breast that you find yourself must be brought without delay to your physician. I think this is more helpful than mammography, but i'd urge you to comply with your physician's recommendations about breast imaging. Only a pathologist can tell for certain whether you have breast cancer based on analyziing tissue.

Agree w Dr.: Friedlander. Need evaluation to know one way or another. Breast cancer sx’s can include a mass. Masses that are painless, irregular ; hard are more suggestive of cancer but they can also be tender, painful ; soft. Swelling of breast; thickened, red, skin; non-milky nipple discharge; new retraction of nipple, puckering or irritation of skin or pain ; sometimes swollen lymph nodes under arm(s).
