Saw a show on tv and they mentioned something called breast fibroadenoma. what is that?

Not cancer: A fibroadenoma is a benign lump in the breast. It has a firm feel to it, and is fairly common in the younger population.

Benign tumor: A fibroadenoma is a common benign breast tumor. They are generally firm, somewhat mobile, smooth walled, painless, and slow growing. The definitive diagnosis can only be made by pathologic study which requires either a biopsy or removal of the mass.
