Stage 1 Patient
Try not to freak out. At your age, your body is going through changes as hormones are reeking havoc all the time. I would normally tell someone of your age to stop touching it. Check it on the same day for at least 2, maybe 3 months. If it's still there have a dr check it. With your history of cancer though, you should have it checked right away. Unfortunately anyone at any age can get breast cancer. Prayers to you.
