Cannabis Science, Inc. (OTCBB:CBIS) a pioneering U.S. biotech company developing pharmaceutical cannabis (marijuana) products, is pleased to provide the latest photos and information on patient three’s progress.

Cannabis Science continues to work closely with its third patient, who is self-treating his otherwise resistant Squamous Cell Carcinoma. The patient has seen dramatic improvements. He has been applying a topical cannabis extract to his cancer, and has seen a large reduction in the tumor masses. Dr. Melamede spoke with the patient this morning, who stated that 80% of the rim that remained from the large tumor on the left side of his head was now gone. The newly posted photo was from over a week ago.

After his last visit to his oncologist (prior to the newly posted photo), the physician explained that he is concerned there may be more tumors on his head that have not yet manifested. The oncologist then instructed the patient to apply the cannabis extracts to his entire scalp. As a result of more extensive topical application of the medicine, new areas have reemerged and are also dying. For example, a new tumor emerged below his hairline. He treated that tumor in the same manner as he has treated the others. He reported that the new tumor had fallen off and left a small hole, similar to what had occurred on his arm (we have not shown these tumors). The rise and fall of the new tumor will be photo-documented when we receive new photos.

Despite the severe pain resulting from additional exposed areas as more tumor mass dies, he is happy to have chosen this route of treatment as opposed to surgery that would have remove most of his scalp and a good portion of the top of his skull. In order to help with the pain and allow for better sleep, the patient is also now taking the extract internally.

The patient stated, "As for my head... the oncologist was amazed by the progress... as the one tumor on my right side is now almost down to conforming with the natural shape of my head and he thinks the others are being killed off too but predicted it might be a couple more months before he could declare it works... Cautious optimism. Also the doctor said that he is hopeful that this works, as there is no known chemo that cures this type of cancer."
