[|Human|] I am 18. I dont have large breasts but my left one is about double the size of my right breast. I can feel a large ball like lump in the left one. It used to hurt about 4 years back but I had read that new breast growth can sometimes feel like a lump and so I never gave it that much attention. It has not grown over the years but it  still hurts sometimes if I run of wear a fitted top(I dont wear fitted tops anymore because the difference in size becomes more noticeable as well.) Recently my Grandpa had a lump removed from his prostate gland although it was not cancerous. Should I take the lump in my breast more seriously?
[|AI|]  Welcome to Chat Doctor .1. Yes you need to take your lump seriously.2. Difference in the breast size is no at all normal.3. As soon as you can get appointment with your doctor and get examined.4. If you are my patient I would have asked for an ultrasound scan, which will rule out presence of any lump and what it consists of and its nature.5.Don't ignore until it complicate. Wish you good health. Anything to ask ? Do not hesitate. Thank you.
