A little known secret of cancer means that oncologists must practice “the rule of 3”.
This secret is that if you fight cancer with some technique, cancer will *adapt* to survive. It will actually change how it operates to protect itself, almost like an intelligent thing.
For this reason, when oncologists attack cancer, they try to do so with three different techniques, all at once, to overwhelm its defensive ability to adapt.
The adaptability of cancer should never be underestimated.
