Nope: The most common symptom is the presence of a lump in the breast. Other symptoms include nipple discharge, nipple inversion, skin indentation, and breast pain. A skin rash or redness is usually due to an infection, although inflammatory cancer may appear as such. In reality, the majority of people diagnosed with breast cancer have no symptoms whatsoever.

No: Generally this is not a common sign of cancer especially if there's been any trauma to the breast. There is a rare type of breast cancer called inflammatory carcinoma that may sort of look like a bruise early on, but it is extremely rare.
