Cancer death rates decline, but it’s not because of treatment. The report shows a significant decrease almost entirely due to screening and diagnosis of precancerous lesions–colonoscopy removing polyps.
Treatment has extended lives but the improvements in survival for patients with advanced colo-rectal cancer, lung cancer, breast cancer, pancreatic cancer, kidney cancer, bladder cancer are measured in weeks to months. The effect is a small delay rather than decline in the death rate.
