Cannabis Science, Inc. (OTCBB:CBIS.OB) a pioneering U.S. biotech company developing pharmaceutical cannabis (marijuana) products, is pleased to release new updated photos from the 3rd cancer patient self-administering cannabis extracts. This patient has severe squamous cell carcinoma on their head that was resistant to chemo and radiation therapy, which left the patient with large tumor masses on their head. With these new photo updates you can see the drastic change in appearance of the tumors and how the topical cannabis extract is killing them.

Cannabis Science has been working very closely with this patient and is continuing to see vast improvement to his treatment resistant squamous cell carcinoma. Prior to using cannabis-based extracts this patient had received radiation and chemotherapy for his condition. This patient notices a huge difference between the treatments and had stated, “While on radiation treatments, each day was stressful and after each treatment I felt horrible as if my entire body was dying organ by organ. While using the Oil, I have noticed that my overall health seems much better. I sleep the recommended hours, unlike the insomnia I suffered while on radiation, and unlike the radiation that caused the restless sleep and nightmares, on the Oil I sleep like a baby.” The patient also mentioned that while showering they would see bits and pieces of the tumor falling off with the water as he was cleaning his head. This patient is very pleased with the results of the topical cannabis extract so far and said he enjoyed absolutely nothing about radiation and felt constantly sick and just overall unhealthy, but with using the oil he said, “I feel myself being restored, not tortured.”

Initially, when the patient began the self- administration of topically applied cannabis extract, the tumor was a solid mass (Figure 1). Subsequently, the extract killed some of the mass and a “cavern” was formed, (Figure 2), followed by the “roof of the cavern” collapsing. The latest photo (Figure 3) shows that the remaining “cavern wall” after pieces progressively have fallen off during the daily shower. Figures 3 and 5 show the lesions are weeping less, flattening out, and their diameter are beginning to shrink.
