I had colon cancer. I could press any place on my body and had pain and I could hardly lift 10 lbs of sugar off the shelf in the store to put it in the basket to purchase. Went to see a doctor and he asked me how long ago was it that I had a colonoskapy (sp) lower GI? I said about 5 years ago and when he got the paper with the results his reply was you don't need on but every ten years and that was the end of that so no help from the medical field. Went to a herbalist and what I thought was wrong with me was verified. Went to a friends and he had a rife machine producing between 120 to 140 watt out put believe max is 250 watt should never go above that for a human for treatment. When using a rife machine I highly recommend drinking a gallon of water starting about 15 to 30 min before starting treatment. I do not know the time that I spend for the treatment or what frequency but I had 3 treatments and waited for 2 days and then had 3 more treatments and that was all there was to it, no side effects. Have not been back and its been over 2 years now and to answer your question I would have to say yes and it depends on which machine you are using
