Thank you all for your replies and comments. I only first heard of it today and was directed to a website: http://www.fudahospital.com/en_asp_new/ for more information. It appears that it's very much a treatment based in Asia.

Brother 51 Y/O
Had a biopsy to remove lump in throat
Recently been through Radio & Chemo
Is in recovery now and trying to deal with post issues
Has had 2 operations to allow food/drink go down throat (unsuccessful)
They say the throat is wide enough but it's the muscles are the problem with the swallowing action
Still feeding through a Peg
Has recently had another biopsy and the cancer is back
