I applied DMSO (and aloe vera gel from my plant incase it irritated my skin) to the back of my hand to treat a squamous cell carcinoma. I applied both twice a day for around a week and it was no longer visible. I continued to apply it once a day for another week or two until I visited the skin cancer clinic to have the area excised (just in case). The pathology report showed there was no malignancy left. Not only did it get rid of the SCC, it also got rid of the red, itchy and painful scar where the SCC had grown.
