Safe for an advanced stage cancer patient age 83 to use Rife if he has cancerous lymph nodes near Aorta?

Greetings,

Just typed out a lengthy post that I lost, so will keep it simple - checking to see if it is safe to have an elderly, exhausted, cachexia-wasting man try Rife with cancer in lymph near his aorta - doc told him he would die in less than a minute once the cancer breaks through so he is a bit nervous. He has been through a year of ozone 2x per day, coffee enemas 3x per day and scads of other cancer protocols. He is tired but willing if it is safe.
Thanks!
