Former GOP Sen. Ben Sasse On ‘Nasty Drug’ to Treat Stage 4 Cancer

Advertisement Early-stage pancreatic cancer is often difficult to detect through imaging, which can delay diagnosis until the disease has progressed.

Sasse said he was prescribed 55 milligrams of morphine following his diagnosis to manage severe pain. In subsequent months, he reported that treatment with daraxonrasib reduced tumor size, allowing him to lower his daily morphine intake to about 30 milligrams and lessen side effects such as nausea and fatigue.

Sasse said his pain has decreased significantly, estimating it is about 80 percent lower than at the outset. He also reported a reduction in tumor volume in his torso of roughly 76 percent.
