Q:

I have a small bump under my right arm about the size of a dime. It is near the surface of the skin, but definitely beneath it; it can be seen on its own without having to feel around for it or anything. I have heard that breast cancer can occur around the sides of the breast as well, and this bump is along the area of my breasts, but closer to my back. I think I noticed it about 3 months ago and it has not changed at all; it's not red, has no hair, isn't swollen. What is your suggestion here? Does the Health Center offer professional breast exams? Is this necessary? (I'm 19 years old, if that matters.)

 

A:

There are many possibilities of what this could be--a sebaceous cyst, a plugged sweat gland or hair follicle, a fatty deposit, a lymph node (less likely due to how superficial to the skin you describe it) and much less likely a tumor.  We do breast exams and evaluation of any skin bump either by exam or if necessary, biopsy.  So yes, do come in so we can take a look and a feel.
