Again, the chart that you show is skewed to convince patients to spend their money. How many would bother if thet saw the real chart that Tony posted?
You need to stop being so gulliable and dig deeper. You are about where I was 15 years ago.
My sister is an M.D. and she said that while Oncologist will suggest that you line their pockets by taking chemo and radiation, 90 percent of Oncologists would never do chemo or radiation themselves. That is also published numbers.
Get the total number of people that get any cancer each year, substract the number that die. What is left? Divide that by the total. I know, crude but close enough.
Chemo only works for 3 or 4 specific easy to cure cancers. Even then, the cancer almost always come back because the cause is still there.
