Cannabis Science, Inc. (OTCBB: CBIS.OB) a pioneering U.S. biotech company developing pharmaceutical cannabis (marijuana) products, is pleased to provide new photographs of the existing treatment for patient three who has a “worst case” of treatment resistant, Squamous Cell Carcinoma. Cannabis Science has received positive feedback from both the patient and his Oncologist. These photos show the progressive reduction of the tumor masses that has occurred within the months of treatment.

Oncologists have stated that this is the worst case of squamous cell carcinoma, and last week, the patient’s oncologist said the results from the topical cannabis extract are “astonishing.” So instead of needing any surgery this month he is to go back and see the oncologist in June. The patient's wife, who could not even look at her husband’s head months ago, has stated that it looks as if 75% of the tumors masses are gone.

Since Cannabis Science has been working with this patient extensively, Dr. Robert Melamede has provided lots of support and expert scientific advice during the treatment process. Patient three came to Cannabis Science with hope to find a treatment that would work. Due to his extremely severe case of squamous cell carcinoma, his surgeon wanted to remove his scalp and a good portion of his skull. Instead he opted for 135 radiation treatments, but the remaining tumors became radiation and chemotherapy resistant. Dr. Robert Melamede informs that, “Cannabis extracts have the unique ability to holistically improve health. They simultaneously modify numerous biochemical pathways to produces a healthy concerted action.”
