I have a lump just under my skin - on my chest/breast - it's JUST above my breast not actually in my breast itself- under my bra strap.
It's painless, hard, feels attached the skin, feels smooth, not perfectly round though, the skin is raised slightly and red - it's NOT a cyst (Yes I poked a needle in there to see if it would drain)
It "grew" in the span of one week - I thought it was just a pimple, maybe a boil - but it never hurt - and never went away (I've had it for a month) so now of course I am worried and I am convinced it's cancer...
ETA: I mad an appointment 3 weeks ago - soonest I could get in was for this coming MONDAY! UG!
