Does male breast cancer have different symptoms from female breast cancer?

No: They have in common the same symptoms -none --that is what makes this cancer difficult to initially detect, but share the same signs - mass, inverted nipple, breast skin dimpling or redness, bloody or clear nipple discharge, nipple ulceration. Men have the same prognosis as women stage for stage but often present later and I do not know why(i am a man) procrastination -too busy-immortal syndrome.

No: Not really, except that women check their breasts a lot more frequently than any man does. So, often the stage of male breast cancer is more advanced when diagnosed.

Not really: Most breast cancers are without symptoms. That is why many are missed. Males having such little breast tissue may notice a lump earlier but not always so many go undetected because few realize that men are also susceptible to breast cancer.
