A major shift is unfolding in the field of skin cancer prevention, ignited by new research showing that an everyday vitamin supplement may prevent many cases of the worldās most frequently diagnosed cancer.The supplement in question is nicotinamide, a form of vitamin B3.
Whereas previous studies hinted at a potential benefit, the latest research ā spanning more than 33,000 US veterans ā suggests that adding this simple vitamin pill to daily routines could dramatically lower skin cancer risk, especially for those who have already experienced their first case.
The scale, breadth and clarity of this evidence are driving calls to rethink how skin cancer is prevented.
Skin cancer is the worldās most common form of cancer. Non-melanoma types, including basal cell carcinoma and cutaneous squamous cell carcinoma, account for millions of new cases each year.
These cancers are linked to cumulative sun exposure, fair skin and ageing. Existing prevention strategies focus on avoiding ultraviolet (UV) rays and using sunscreen, but rates continue to climb, and patients diagnosed with one skin cancer typically face a stubborn cycle of recurrence.
Enter nicotinamide, a cheap, widely available supplement. Researchers observed that this form of vitamin B3 bolsters the skinās natural repair systems after UV damage, reduces inflammation, and helps the immune system detect and clear abnormal cells.
