How does a TCM approach to cancer differ?

It is my understanding that TCM focuses on cancer prevention, thereby keeping Qi and Blood flowing within the body so that disease cannot manifest. However, we're just starting to discuss in our Diagnosis and Herbs classes some of the treatments for cancer. Our Herbs teacher recently told us that cancer is often viewed as a heat pathogen that has become toxic. We learned an entire category of herbs that clear heat-toxins from the body. I'm also aware of quite a few acupuncture points that clear heat (i.e. LI 11). I also believe that TCM dietary prescriptions, tui na, and qi kung can prevent and rid cancer from the body. The beauty of our medicine is that it operates off of the inherent trust in the body to heal itself, whereas Western medicine virtually destroys the body for cancer treatment.
