i am a 14 year old female and i have noticed two mysterious lumps under my armpits. under my left armpit, i have a red, itchy spot and no hair is growing there (i've stopped shaving for the past couple weeks because it hurts). it itches all day and i try not to scratch but i always end up sneakily scratching it through my shirt. Under my right armpit, i have a small, pea sized lump. At first i thought it was a pimple because of the size and tenderness but it wouldnt pop or anything. the next day, i felt around it and could feel it through my skin. it's hard to describe but i can like feel how far down under my skin it goes. there is a constant, dull aching under my whole right armpit and sometimes, like during gym, my whole right arm will start to ache. Also, i have had a stomach ache for about two months. I sometimes get heart burn but it doesnt feel like that. Its around my belly button and its the same aching that is under my arm pit.
I have heard of 16 year olds having breast cancer but it just seems like not possible... i'm too young, right?
Also, girls in my class joke around saying that wearing your bras when you sleep give you breast cancer. I sometimes wont take off my bra for a whole week because i feel naked and gross without it. I have stopped wearing it when i sleep and am just around my house but i dont like it. please tell me if this is true so i can stop!!
My breasts arent sore unless i squease them firmly but thats normal right?
