Im only 14 but this lump has been there for a few months and my nipples have been flaky and peeling for a little less. And sometimes my nipples itch real bad and look a little red. I know that breast cancer is not common in teenagers but i have been watching the lump for a little over a month and it has not changed nor moved. Breast cancer is very common on my dads side of the family. I usually get my period every 3 months for 11 to 14 days. Its been like that for a year and a half. Please help me.
