Some people are using Marijuana oil for Cancer treatments in animals as well as humans. You might look into it. Here is a link to a thread a friend started after he was diagnosed with terminal liver cancer and given 6 months to live. He declined chemo and radiation. Instead he went home to die but was convinced to try Rick Simpson oil, THC-CBD oil. He was supposed to be dead a couple months ago but is now declared cancer free. He still has something going on with his liver but now they say no cancer. Someone in the tread is going to try it on their dog that has cancer. Good reading.
