Hard spot under my left armpit. Used to be a bump but it's now flat and hard. Not painful, one spot on is rough feeling, could it be early cancer?

Checkup by MD needed: I bet it is probably a resolving acne vulgaris lesion or irritation from either shaving or a deodorant. You might let a pediatrician or family doctor take a look at it to be sure. Stay safe! ...Read more
