My Mom is medium risk she would be high risk but she did not go into puberty in till she was like 16.There is breast cancer in the family my aunt had it and I think some other family members have had it.I started puberty at like 9 and by 11 I was a B cup and had my period.How high is the chance of me getting breast cancer?When should I get a mammogram(Im 13 so I dont need one for a long time)?When should I start doing self checks?
