There is no scientific answer to your question. While cannabis appears to possess a variety of potentially beneficial effects for patients with cancer, no actual parameters for successfully treating any cancer with medicinal cannabis have been determined through clinical science. I strongly recommend continuing conventional medical evaluation and treatment along with any medicinal cannabis use. Many medicinal cannabis preparations are available that will help reduce the discomfort of various symptoms that typically accompany cancer and cancer treatment, including nausea, appetite problems, mood problems, and chronic pain. Balancing THC with CBD appears to moderate THC effects in helpful ways, and many patients have reported CBD dominant preparations helpful for their symptoms, but this is often a matter of individual preference arrived at through cautious experimentation.
