I am a 17 year old male and around a month and a half ago found a small lump under my left nipple. I went to the doctor and was given Brufen tablets but after about 3 weeks there was no change and so i went back. She has now booked me into a screening clinic to check it out.
I decided to look around the internet and found that male breast cancers are very rare, especially at my age, and that the most likely cause was Gynecomastia.
However, around the lump i sometimes get uncomfortable pains, especially when sitting for long periods of time (such as in school).
Does anyone have any ideas of what they think it may be?
