Vitamin A and the Fight Against Breast Cancer

Laboratory tests indicate that retinoic acid, a derivative of vitamin A, may someday act as a weapon in the fight against breast cancer. Researchers exposed pre-cancerous breast cells to retinoic acid and observed the cells transform back into normal, healthy cells. However, cells that had already become cancerous were unchanged suggesting there may be a narrow window of opportunity for retinoic acid to be helpful in stopping the progression of breast cancer. Further research is needed to see if this approach is viable in animal — and eventually human — models.
