Hi. My son recently found a hard
lumpLumps in the breasts directly under his left nipple. He is 13. The
lumpLumps in the breasts is very small, only 1 cm x 1cm and it is not
painfulPainful menstrual periods. Also, his left and right nipples seem to be inverted a lot. They are not always inverted, and this happens moreso on the left. Should he go to the doctor for this? Thanks.
