A new study was presented at an annual cancer meeting (ASCO) in Australia at the end of May. The researchers found that patients that took 500mg of Nicotinamide (a form of vitamin B3) twice a day cut their chances of developing new non-melanoma skin cancers (basal cell carcinomas and squamous cell carcinomas) by 23%. There were 386 participants in this study averaging 66 years old and all had previously had a non-melanoma skin cancer. Half of the people took the Nicotinamide and the other half took a placebo. The patients that took the Nicotinamide had less new non-melanoma skin cancers or reoccurrences than the patients that received the placebo.
What does this mean? If you are at risk of getting non-melanoma skin cancers or have already had one this might slow the growth of new cancers or the return of the same cancer. This study however did not totally stop the cancers so this is not a miracle cure but, it is promising. Also this study did not include melanomas which are the most dangerous of all the skin cancers.
Even if you take Nicotinamide, cancers are still a dangerous threat and so you should always protect yourself from the sun. Covering up and seeking shade during the peak sun hours are great ways to protect yourself and always wear sunblock when you expect sun exposure.
