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

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.
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.
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.
