Hi Bill, I’m sorry to hear about your wife. What state do you live in? If you live in a state where medical cannabis is legal, I would recommend that you purchase the cannabis oil from a legal dispensary, instead of making it yourself. I’m including a part of the above article regarding breast cancer:” There are different types of breast cancer: estrogen-receptor positive or negative, progesterone-receptor positive or negative, HER2 status, triple-positive and triple-negative. Anecdotal and lab evidence seems to indicate that high levels of THC actually INCREASE the growth of cancer in estrogen-receptor positive and triple-positive types. Anecdotal and lab evidence shows that using a higher ratio of CBD to THC oil is best in these cases.”

I would recommend a ratio of 4:1 CBD to THC but I can’t recommend a strain. The cannabis oil sold at legal dispensaries is tested for CBD to THC ratio consistency.
