Dr Greger has videos explaining that patients overestimate the efficacy of pharmaceutical and surgical interventions! If they really knew the odds of success of these interventions and the odds and severity of side effects, they may be more inclined to adopt lifestyle changes for prevention, management and reversal of various chronic diseases.

The rest of this article touches upon these questions:

How Effective Is Cancer Treatment?

An insightful video by Dr Greger:

(2018) How to Win the War on Cancer

(5 mins) Transcript. Dr Greger's summary: "How effective is chemotherapy for colon, lung, breast, and prostate cancers?"

Excerpts from this video:

“Over the last several decades, medicine has waged a major war against cancer, concentrating on earlier diagnosis and improved therapy. The war is not being won. Nevertheless, medicine shows few signs of admitting that its strategy may be flawed. In this it resembles a World War I general who stated: ‘Casualties: huge. Ground gained: negligible. Conclusion: press on.’

How effective is chemotherapy?

If you look at the contribution of cancer-killing chemo to five-year survival in cancer patients, it’s on the order of only about 2%. Now, there’s some pediatric cancers we’ve gotten good at treating, and testicular cancer and Hodgkin’s disease are exceptions, but if you look at our most common cancers—colon, lung, breast, and prostate—the success rate is only about 1%. Meaning like, out of nearly 14,000 colon cancer patients, only 146 lived out five years thanks to chemotherapy. So, the chance of survival benefit is like one in a hundred, but doctors don’t tell patients that. “…New chemotherapy drugs are promoted as…major breakthroughs, only to be later quietly rejected.” “The minimal impact on survival in the more common cancers conflicts with the perceptions of many patients who feel they are receiving a treatment that will significantly enhance their chances of cure.”

… and Dr Greger goes on to explain that lifestyle factors play a significant role in cancer prevention.

How Effective Are Early Detection Procedures?
Prevention! Prevention! Prevention!

When it comes to serious conditions like heart disease and cancer, the best strategy is PREVENTION, PREVENTION, PREVENTION!

The superior doctor prevents sickness. The mediocre doctor attends to impending sickness. The inferior doctor treats actual sickness. — Chinese saying.
