How this protocol works
In plain language
Basal cell carcinoma (BCC) is the most common type of skin cancer, affecting millions of people annually. It arises from basal cells in the skin's outer layer and is primarily caused by cumulative UV radiation exposure from sun or tanning beds. BCCs typically appear as pearly bumps, flat lesions, or non-healing sores, usually on sun-exposed areas like the face, neck, and ears. While BCCs rarely spread to distant organs, they can grow locally and cause significant tissue destruction if untreated.
CRITICAL: BCCs require medical treatment - typically surgical removal (excision, Mohs surgery) or other methods like curettage, cryotherapy, or topical treatments for superficial lesions. Regular skin checks are essential as people who've had one BCC have a 40-50% chance of developing another within 5 years. Supplements may help PREVENT new BCCs but do not treat existing cancers. Sun protection (sunscreen, protective clothing, shade) is the most important preventive measure. See a dermatologist for any suspicious skin changes.
Nicotinamide (Vitamin B3)* is the best-studied supplement for skin cancer prevention. The ONTRAC trial showed 500mg twice daily reduced new BCC and squamous cell carcinomas by 23% in high-risk patients (those with prior skin cancers). It works by enhancing cellular energy for DNA repair after UV damage.
Vitamin D* has an interesting relationship with skin cancer. Sun exposure produces vitamin D but also causes skin cancer. Vitamin D itself has anti-proliferative effects and supports normal skin cell function. Those avoiding sun for cancer prevention should supplement vitamin D.
Green Tea Extract (EGCG)* has photoprotective and anti-cancer properties demonstrated in laboratory and some human studies. It can be taken orally or applied topically.
Selenium* has mixed evidence - some studies suggested benefit while others (like the SELECT trial) showed potential increased risk in selenium-replete populations. Only supplement if deficient.
Beta-Carotene* and other carotenoids may provide mild UV protection but evidence for skin cancer prevention is limited. Avoid high-dose supplementation in smokers.
Vitamin E* is an antioxidant that may help protect skin from UV damage.
Omega-3 Fatty Acids* may reduce UV-induced inflammation and immunosuppression.
Polypodium Leucotomos* is a fern extract with demonstrated photoprotective effects, reducing sunburn and DNA damage from UV exposure.
Expected timeline: Nicotinamide effects seen within first year of use. Prevention is ongoing with sun protection and supplements. Regular dermatology surveillance is lifelong.
