You mean it might stimulate the gene that stimulates a particular substance that might be envolved?
Fighting cancer is so complicated that it rivals a major war in complexity. Cancer cells actually fight back when you try to treat them. For this reason, it is now recommended that you attack them with three different cancer treatments simultaneously, to overwhelm them.
Before cancer can begin, the bodies defenses have to be partially deactivated. Cancerous cells happen all the time and normally they are destroyed before becoming a problem. The cancer must be of a “successful” type or it will die. It must be able to divide yet produce other cancer cells that are both cancerous and functional.
Then, in a manner unique to cancer, it must actually stimulate the body to grow extra capillaries to feed it more than normal cells, as it consumes much more energy. And it must also defeat the “self-destruct” mechanism that cells have that prevents them from endlessly reproducing themselves instead of being replaced by stem cells.
Finally, it must change the chemical composition of its outer coat, to make itself slippery, so that cells can break off from each other, in metastasis, so they can travel through blood vessels to a new location where they can become a new tumor after changing back and adhering themselves to normal cells.
The complexity just keeps growing from there. And growing.
