Childhood leukemia used to be overwhelmingly fatal, and early chemotherapy trials also only managed a couple months of remission. Researchers were even criticized for subjecting patients to harsh side effects to no apparent benefit. But thanks to that research, most patients are now cured; per capita death rates from childhood leukemia are down 14x from the 1950s, mostly driven by improved treatment.
Daraxonrasib is an incredible invention on a technical level, and a meaningful step forwards in the treatment of many cancers. We'll need a couple more equally incredible inventions to be able to cure pancreatic cancer.
CT scans emit ionizing radiation.
MRI contrast can buildup and be retained in the body over repeated administrations.
The scans can produce false positives, surface benign abnormalities which result in a wild goose chase, cause severe patient anxiety and healthcare burden, and result in over-treatment.
And of course doing this on a whole population level is not cost or time effective.
It will never be cost or time effective if we never try. I'm paying out of pocket every year for an MRI scan, this was my second year this past year.
