Studies find combination topical immunotherapy has a cure rate above 95%
When I started my practice in 2007, I looked for a low-cost alternative to skin cancer surgery. Dermatologists in Australia, Europe, and the UK were using Imiquimod 5% Cream, sometimes with 5-Fluorouracil, to treat basal cell and squamous cell carcinoma.
Adding Tretinoin 0.1% Cream to the combination, I created "The Shen Cocktail." Tretinoin 0.1% Cream peels the top layer of skin. Imiquimod 5% Cream and 2% 5-Fluorouracil signal an immune response to attack cancerous and precancerous skin cells.
I've used "The Shen Cocktail" on over 5,000 patients over a ten-year period. Researchers at University of Miami have concluded the cure rate for this combination topical immunotherapy is above 95%.
