Wouldn't you accept treatment though if it could extend your life by years? Not all treatment is painful and or debilitating.
Maths professor Hannah Fry has had cancer, she recently made a
program about it, and in particular about the odds with treatment.
Of 100 cancer patients who have chemo after surgery, 80 would have lived even if they had refused chemo, 15 will die even though they had chemo, and the chemo will save the life of just 5. The problem is that you
don't know who is who, so for every 5 lives saved 100 patients had to go through all the side effects. (See from 13m30s)
It's interesting that the doctor thinks that's too difficult a concept for patients to understand, and advises the patient to have the chemo anyway.
When I was waiting to find out if my bowel tumour was malignant 10 years ago, I'd pretty much made up my mind to take whatever time I had left without buggering it up with chemo. (But it turned out it was still benign anyway.)
There's just been someone on the radio saying that Deborah James gave her the confidence to go to the doctor. Good, but I really don't understand why anyone would be too embarrassed to go to the doctor if they're passing blood, and I embarrass quite easily.
