i would strongly advise against betting you life on alternative products for lymphoma, especially considering current chemotherapy for lymphoma is quite good.

In my opinion, the single largest advance in medicine in the last hundred years isn't vaccines or antibiotics, it is the randomized clinical trial. A randomized trial is the only way to determine whether or not a treatment is effective.
