Hi, m 26yr old. Since the last 4yrs, I have a small lump (maybe about 0.5cm) in my right armpit. My doc did a breast examination and an ultrasound reported multiple cysts in each of my breasts (1mm, 5mm, 4mm). He said a mammogram may not be necessary and gave me Vitamin E pills. I finished the 3 month course. This was 4yrs ago. I haven’t gone back to him. But still have the cysts in my breast and the lump under my arm. I cannot detect any growth in the past 4yrs, they remain of the same size. They donot move around too, fixed to the origin. Pls advice. Could this be cancerous?
