There is such a thing as teenage breast cancer, but the risk is very low. For a woman at age 25, she has about a 1 in 20,000 chance of getting breast cancer. A teenager aged 16-20 has an even lower chance.

However, the risk of breast cancer increases greatly as you age (at 35 it jumps up to 1 in 622!). This is why it is important to learn at a young age how to examine your breasts and what to look for. I would not worry too much about getting breast cancer at such a young age, but there is always a possibility and its very important to learn the normal feel of your breasts so you know when something abnormal happens.
