My worries are , I've had a lump under my right armpit for as long as I can remember but i was just a small one, about the size of a bean maybe. Anyway, I have notice in the last 2 1/2 years that it has gotten bigger and it is way sore, espeacially when I touch or the area. I have also notice some slight pain or soreness when I touch the side of my right breast. Should I be of great concern and see a doctor? I also have notice some knots along the side of right breast. Please Help A.S.A.P
Thanks to anyone who can give me some advice
