Hi, good for you that you are investigating safer methods of treating your affliction. Oxygen therapies are excellent for treating cancer, for cancer cells can not grow in an environment where oxygen thrives. However the real trick is getting enough oxygen to every part of your body, and especially the afflicted area. Curezone has an entire forum dedicated to the discussion of different oxygen modalities, and here it is:
McCabes's books are THE source for information on oxygen/ozone and related theapies.
Furthermore there are alternative doctors who use IV ozone therapy, ozone chambers, etc., to treat cancers. The idea is, as McCabe's most well known book is titled, to flood your body with oxygen. My suggestion is read through as many of the posts in the Oxygen forum as you can and get hold of the books. You will then know more about all the many different approaches and can get started on your way back to health.
Many blessings to you.
