Today marks a loss of 18 pounds from my heaviest, and I noticed my breasts are noticeably bigger. It's possible they look bigger because my stomach has dramatically shrunk. I've done weight loss before and my breasts usually get smaller. I am 25 years old, and I heard age can be a factor in breast growth. Will my breasts stay the same size or will they get smaller with weight loss, and will my breasts ever get naturally bigger as I get older?
