So sorry to here this @FortyFi his choice of alternative therapy is the right choice as mentioned earlier by @Rogue on staying positive in mind body and spirit it important! I research stuff all the time and have found a podcast called “ Cannabis health radio” to be very inspiring ! RSO is the way to go IMO As mentioned by Corey Yelling and Ian Jesup Here is their link
http://cannabishealthradio.com/ I encourage you and your father to start listening, or even contacting them personally.
It is always stated in this pod cast that multistrain oil is best in treating cancer with high high THC ! Which is also mentioned by Rick Simpson himself I wish you and your father thoughts and prayers in battling this terrible disease.
