I am a 17 year old male. I have noticed that my right breast has
become somewhat enlarged. I saw a doctor and she told me its normal
because of the hormone changes that people undergo at my age. I dont
think she knew what she was talking about considering that she was
trained in a foreign country. I was wondering if it could possibly be
anything else?

I suggest that you get a second opinion from a different physician. I
don't mean to alarm you, but breast cancer can occur in males, and a
unilateral swelling can be one of the symptoms. Some of the material
here may be of interest to you:

Here's something that says that the doctor was right:

WHY DO PEOPLE NOT TRUST THEIR DOCTORS?!

This *is* a typical and normal thing that happens.  Please watch it
though, I had the same sort of thing that was dismissed as
Gynecomastia before, but it later turned out to be an infected sweat
gland. (But, yeah, the turning green and yellow and full of puss kind
of tipped that off.)

If you're fully through all of your sexual development, and you still
have a significant breast and it does not go away, you can consider a
mamosectomy, (Removal of the breast) which would remove the breast
tissue and leave you with a body that you're not uncomfortable with.
