I have not heard that it is something that would treat colon cancer. If I had colon cancer I would try all 'do no harm' treatments. Chemo and radiation can always be used but hitting an evil with other evil does not make sense. It is everyone choice to what treatment they feel is right for them.
If you have colon cancer, and need some help finding good proven resources for cancer I will be happy to help you, nadine@jesichashope.org I can get you a free consultation to get an opinion of treatment as well. Cancer is serious business, you have to hit it hard and kill it.
There is a very good video found on the resource site http://www.jesichashope.org
I think you will find some good info there and help you make an educated decision. All resources and support is free.
