Oh Chris, I am so sorry
but it's NEVER too late!
I'm going to leave Rife info up to those far more experienced to advise here, but in the meantime, feel the need to share some other possibilities which won't interfere with any form of Electrotherapy.
Visit a fellow member's website: http://www.heal-me.com.au
Then please also look at what Dr. Howenstine advises here:
Excerpt:
"Nobel Prize winner, Dr. Otto Warburg, discovered that he could produce cancer almost at will by lowering the oxygen level of tissues by 35 %. Tissues with low oxygen content are acidotic and raising the ph with alkalinizing therapy greatly increases the oxygen content of the tissue causing cancer to disappear. As we age our ability to keep our tissues well oxygenated gradually fails making the appearance of a malignancy more likely. "
Also go to the CANCER thread on this forum where you can find loads more info.
In the past 4 years, the one 'quickest miracle' treatment mentioned to me personally, involved an elderly lady in Australia, with a stomach full of tumours and given only a month at most to live ... yet 2 years later, when I last heard ... with
Cesium Chloride, she was still doing extremely well.

There is another similar story to your friend's, specifically involving brain tumours on
www.curezone.com ... I first have to source it ...
watch this space!
Love, light and loads of Raphael's healing coming your friend's way
