I've done a lot of research about Edgar Cayce and how he recommended using Castor oil to heal people. This oil is also known as Palma Christi or the "Palm of Christ". Edgar Cayce mentions castor oil many, many times in his readings. You put it on a poultice and put over the area in warm packs. If I had cancer, I would definitely give it a try.
I would also try Essiac tea as I did a lot of research on that also and it helped a lot of people with cancer in Canada.
You can look up both Edgar Cayce and Essiac on the internet and find out a lot of good information.
