hello , my name is Estrella and i am 17 year's old. i went to the doctors a while ago and i had an incedent in school where a kid punched me in my left brest. my doctor had told me that i have a lump on my left breast and she checked my right breast and found a lil lump on that side too . So she want's me to go for a sonogram to make sure it isnt nothing serious . and im just really curious about what it could be ?. also im sorta loosing hair in the from of my head little by little . could it be breast cancer ?.
