Tumor-associated autoantibodies from mouse breast cancer models are found in serum of breast cancer patients. (Most fibroadenomas in adolescents are typical, adult type fibroadenomas and should be diagnosed as such) Giant fibroadenoma Tumors >500 g or disproportionally large compared to rest of breast; More frequent in young and black patients; We consider the term merely descriptive; May be either adult type or juvenile fibroadenomas Risk appears to be slightly higher in those patients with a positive family history of breast cancer. 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.
