Topical Vitamin C Stops Basal Cell Carcinoma

(OMNS Nov 9 2007) The most common form of skin cancer, basal cell carcinoma, often responds to a remarkably simple, safe, at-home treatment: vitamin C. Physicians and patients report that vitamin C, applied directly to basal cell skin cancers, causes them to scab over and drop off. [1] Successful use involves a highly-concentrated vitamin C solution, directly applied to the blemish two or three times a day. Vitamin C is selectively toxic to cancer cells, but does not harm healthy skin cells. This is also the basis for high-dose intravenous vitamin therapy for cancer. [2] Even higher concentrations of vitamin C can be obtained by direct application. The use of topical vitamin C to kill basal cell carcinoma has been known at least since 1971. Frederick R. Klenner, MD, wrote: "We have removed several small basal cell epithelioma with a 30 percent ointment" of vitamin C. [3]

One person, who reported that a 2mm diameter spot on the nose would not heal for months, had it disappear within a week with twice-daily concentrated vitamin C applications. Another patient reported that after dermatologist-diagnosed multiple spots of basal cell carcinoma were coated with vitamin C, the spots fell off within two weeks. [4]

Basal cell carcinomas are slow growing and it is rare for them to metastasize. This provides an opportunity for a therapeutic trial of vitamin C, provided one has proper medical diagnosis and follow-up.

Preparation of a water-saturated vitamin C solution is simple. Slowly add a small amount of water to about half a teaspoon of vitamin C powder or crystals. Use just enough water to dissolve the vitamin C. Using less water will make a paste. Either way, application with the fingertip or a cotton swab, several times daily, is easy. The water will evaporate in a few minutes and leave a plainly visible coat of vitamin C crystals on the skin.

Consult your doctor before employing this or any other self-care treatment. A physician’s diagnosis is especially important, since other forms of skin cancer, such as melanoma, are faster growing and more dangerous. If the vitamin C treated area is not improved after a few weeks, a doctor should be consulted once again.
