How can I tell the difference between "good" and "bad" lumps in my breast?

Michael Tahery (Obstetrician & Gynecologist) gives expert video advice on: What is my doctor looking for during a breast exam?; Can I do my own breast exam?; How common are abnormal pap smear results? and more...

I think people should not really try to do that. I think that they should try to look for something that's always been there, and something that hasn't been there and is new. I think that is the most important thing. If a person can differentiate between what's always been there and what't new that's what they need to do. They've done their job. It's more difficult, even for physicians sometime's to tell if a lesion is god forbid malignant or not. So I think they should just report something new to the doctor and let the doctor handle the rest of that. For example a discharge from the nipple could be very, very beneign and normal, or it could be a sign of something else that is happening. Same thing with a lump, or an unusual pain that does'nt go away.
