What are the odds of a 17 year old getting breast cancer?

< 1 in a million: The incidence of breast cancer in teenage women was recently reported as 0.08 cases per 100, 000 people, so the odds are very, very low. Regardless, any new breast lump should be followed by a physician evaluation.

Very rare: It is very rare and very unlikely for teenagers to get breast cancer. Need to see a doctor for an examination.
