Definitely best to go doctor but if it went away more likely to be hormonal. But don't take out word.

I have such a lump too by the armpit, doc said it's PROBABLY hormonal, I take his word for now but then again a lot of GPs/doctors diagnose things wrong, Jade goody is a good example, so after you've seen the gp, even if he says it's hormonal, make sure you keep going back to have it checked, even if you have to see another gp do it.
