Cannabis Science, Inc. (OTCBB: CBIS) a pioneering U.S. biotech company developing pharmaceutical cannabis (marijuana) products is happy to report that patient #2, who had a Squamous cell carcinoma on her arm, has received her biopsy report. It confirms what was visually apparent from the photo-documentation on our website. Her biopsy was free of cancer cells and she will not need any surgical procedure. Nevertheless, the patient will continue with her self-administered topical application of extracts for a while longer to minimize any chance of any surviving cancer cells in areas beyond what was biopsied.

Cannabis Science Inc., President & CEO, Dr. Robert Melamede Ph.D., stated, “Squamous cell carcinomas have a much greater invasive potential than is typical of basal cell carcinomas. Photo-documentation of topical cannabis extract treatments of patient #2 and patient #3 dramatically demonstrate how the treatment appear to extrude the subcutaneous tumor to the surface as the killing and subsequent healing proceeds. Patient #3 reports continued progress as his tumors appear to shrink and the pain levels continue to improve. The patient's wife commented that about 75% of the large tumor mass is gone. We will continue with ‘live updates’ as new pictures and physician reports are made available to us.”
