...are you saying that if you had spent years developing this treatment that uses in combination various chemotherapy drugs along with one other drug that has been used daily for over 25 years that you would just go out and tell everyone how to use these two drugs...
Of course not but there are multiple ways to secure your product (in this case treatment) with special trading marks, licenses or even patents.
This is a simple and honest answer. I think it would be hard for you to convince me that there is no legal way to secure your product.
Just after one treatment, your special formula will be lost. If this is so special then they would send somebody who will make the treatment and describes everything with details later on.
