Where do Thompson's doctors say he is "fine" or has a "clean bill of health" as you assert? I provided a link , in which his doctor says:
Nodal marginal zone lymphomas account for only 1% to 3% of all NHLs. "Some lymphomas are very aggressive, but people with slow-growing types, like Senator Thompson's, more often die from natural causes associated with old age, rather than from the disease,'' Dr. Cheson said.
He said that if Thomson wants to run for the GOP nomination, there is no medical reason he could not, and Thompson would be medically fit to serve as president. Dr. Cheson that there would probably be a recurrence eventually, followed by retreatment with rituximab.
Is this what you call "a clean bill of health", or do you have another link in which Dr. Cheson or another of Thompson's doctors have used such a description?
