I'm 34 yrs old, in general good health. However, 40pds overweight. No history of any cancer in my family. I work out 40 mins everyday. This past Saturday the 26th, my left armpit area was irritating me, I say irritating because it felt like a razor burn. I felt my underarm and found a pea size lump. I did a self breast exam and do not feel any other lumps. On Thursday the 24th, I did shave my underarm, with a week old razor. The lump is small, hard, and I don't have to press down on my skin to feel it, the skin feels somewhat raised, but the lump also feels alittle deep. It does hurt when I touch it and for a little while afterwards, but then pain goes away, at times it can be alittle itchy. I've looked in a minor and don't see really anything out of the ordinary, such as a sore. I know that it can be many thing, cyst, in grown hair, even a sign of breast cancer. I've never had an in grown hair so I'm not sure if there would be obvious signs of that. Looking for advice on how long I should wait to see a doctor, and should I go to a Dermatolgist or Gynologist. And what else could this be, I feel healthy otherwise. However, because of this lump, I'm now obvious a nervous reck! Please give me some advice and THankyou for bring this forum back.
