I think the more important take-away is each patient should find the treatment that works for them. There are many people who are fully accepting/trusting (whatever term you choose) of the "machine". It works for them, don't knock it.
There are other people who want, and/or need, to look for alternatives. Some of them work and work very well. But, some people don't have the stomach for that, or they second-guess the idea that they "could have done more".
I had a good friend die from cancer a few months ago. After the first surgery and round of chemo, his Oncologists told him all was well, full remission. About a year later, it returned somewhere else. More surgeries, more chemo, full remission.
The third time, now in his lungs and brain, they said even with surgery and chemo he had about 6 months to live. Instead, he took the route of alternative treatments in the US, Mexico & Canada. All of these treatments were by fully licensed Oncologists who have been practicing for 20+ years.
Every 3 months his "machine" Oncologists said they were surprised to see him for another follow-up visit. This went on for 5 more years.
