My son is 14 months old. Last Saturday he woke in the morning with a really red swollen nipple on his left side. Since then the redness has gone down but his nipple has started to invert and come back out. His right hand side is completely fine. I can't feel anything behind the nipple and he doesn't complain when touched. He also doesn't try to scratch or touch it himself. He seems other wise healthy. We have been to the local GP who had a look but didn't mention if he could feel anything. He suggested it could be gynecomastia but said it would be rare at his age.He then contacted the pediatric at the local hospital who advised him to start a course of antibiotics and if no improvement they would see him. I'm really concerned this is breast cancer or pagets disease of the nipple. Thought I would see if anyone could give some input if they have experienced this or seen something similar before. Thank you for any response
