Basal cell skin cancers and squamous cell skin cancers are the most common cancers in Caucasians. Squamous cell cancers are of greater concern because of their potential to metastasize, especially those on the head and neck.
Nicotinamide is a form of vitamin B3. It boosts cellular energy and enhances repair of DNA that is damaged by ultraviolet radiation.
The study found that 500mg of Nicotinamide taken twice a day resulted in the decrease rate in the following cancers:
Basal cell 20% lower
Squamous cell 30% lower
Actinic keratosis 13% lower
