Patient discussion about axilla

Q. A lump in my armpit Hi, Last week after the shower I found a small painful lump in my right groin. I went to see a doctor and he prescribed me some antibiotics. I’ve been taking it for 5 days and the lump is still there. I’m 31, usually healthy and work-out in the gym regularly, don’t smoke or use drugs and don’t take any medications. Is that dangerous? Should I go and see another doctor?

A. What you describe sounds like enlarged lymph node. The first diagnosis that’s suspected in such case is an infection that makes it painful. The antibiotics you take need several more days to act, so currently it doesn’t sound suspicious. If the lump persist, it’d be wise to consult you doctor

Q. I located a lump on the surface of my right underarm. I think I am showing some signs of breast cancer. I am 27 years old working lady. I think I am showing some signs of breast cancer. I located a lump on the surface of my right underarm. This lump is of a cherry size and does not pain at all. But I do have pain in my breast. I had my mammogram done which showed no lump and my doctor says that there is nothing to worry and she has given me some medicines. I want to know that if everything is normal then how come these lumps came.

A. there are ways to diagnose if lumps are breast cancer or not. a lump under the forearm can be a sign of an advanced stage of cancer, but it can also mean some kind of viral infection that caused a lymph node to swell up. so if a doctor told you it's fine- he probably checked it out, and it's fine. if you still anxious - go get a second opinion.
