Fibroadenoma is the commonest solid benign lesion that can exist as a solitary mass or multiple masses in the breasts. The injection of sexually immature female rats with 1-methyl-1-nitrosourea results in a rapid induction of premalignant and malignant mammary gland lesions within 35 days of carcinogen administration.
