title: Failure of ascorbic acid to inhibit growth of transplantable and dimethylbenzanthracene induced rat mammary tumors.
abstract: The effect of ascorbic acid on the growth of 7,12-dimethylbenzanthracene (DMBA)-induced mammary tumor and on growth of R3230AC and MT/W9a-B transplantable rat mammary tumors was investigated. High doses of ascorbic acid averaging about 540 mg/day/rat administered orally in drinking water had no effect on the growth of both R3230A and MT/W9a-B transplantable mammary tumors. Furthermore, vitamin C was unable to postpone tumor induction, reduce tumor incidence or prolong survival time of rats treated with DMBA.
