A recent study from Taiwan suggests that diabetic patients who are treated with “metformin” had a lower risk of skin cancer than would have been expected. Further studies are needed to confirm and explain these findings but the authors suggest if you are diabetic and at high risk for skin cancer you should consider metformin as part of your diabetic treatment.
