small lump in armpit

[jakey2]

I'm 34 yrs old female, 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.  However the lump isn't noticable to the eye. 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. What other things can this be.  I'm very anxious and nerves about this.  Please help!

One more thing, everything I've read mentions breast cancer, this lump appeared suddenly, is that generally a bad sign indicating cancer.  Also, what would be the signs if any if this lump was just a cyst.  Very afraid!

Any lump under the armpit (axilla) is concerning.  It could be something as little as a cyst or inflamed hair follicle, but suspicious lymph nodes also present in this area.  

Because of this possibility, I would consider a referral to a general surgeon for further evaluation.  If the surgeon believes that the lump is suspicious, a biopsy can be arranged.  

I would discuss this option with your personal physician.

Followup with your personal physician is essential.
