Is it possible to have breast cancer if your breasts are not fully developed?

Sara: Is it possible to have breast cancer if your breasts are not fully developed?
Just wondering because one of my friends said something about feeling a bump in the middle of both of her breasts, so is this breast cancer, or nothing?

Thanks

YES

No, it’s very unlikely. But the breasts to swell during puberty in both males and females so this is by far the most likely scenario. Also, breast cancer in both breasts simultaneously is extremely uncommon. So, rest assured, it is nothing but normal development.
