breast lump

i started noticing over a period of time that my right breast was getting much bigger than the left one, i didnt pay much attention to it until about 7 days ago, i noticed a fairly big lump in my right breast. it's not painful at all but my right breast has further enlarged and the lump is about a third of my breast, its also very hard and fixed. i had an ultrasound done but the doctor only said that i have one breast bigger than the other. now im starting to get really sore armpit specially the right one and i was wondering if my doctor's diagnosis may be right????
i was also told that since i am 19 years old, i wouldnt be taken seriously....i'm a little confused!!!!

No matter what your age you should be taken seriously !! This could be due to dense breast tissue (lumpy feeling breasts) but it could also be a Fibroadenoma or a cyst; both of which are benign. If I were you I would see another Dr.; a breast specialist if possible. You need a better answer than "one breast is bigger than the other".  That is very poor medical practice to my way of thinking. Get a second opinion but I wouldn't worry that it might be cancer .... not likely at all.    Regards ...

thank you so much, i followed your advice and im going to a breast specialist on thursday.....and you are absolutely right, there are very little chances of my condition being breast cancer, i was unconsciously scaring myself...but then again rather check it than just leave it as it is.
