FDR's Preexisting Condition?

"Is it conceivable that Franklin D. Roosevelt's doctors knew he had widespread cancer in 1944 and still let him run for his fourth term as president? New research makes this astounding argument -- and claims that the physician who supposedly told the truth about Roosevelt's death in 1970 was in fact continuing the deception he had helped create." Slate's Barron Lerner evaluates new claims that FDR may have suffered -- and died -- from cancer.

"How plausible is this research? If Roosevelt indeed had a hemianopsia, it suggests a brain mass, and melanoma would be as likely a cause as any...But all of these symptoms have other possible explanations...Perhaps most important, there is no smoking gun: In all of the documents Lomazow and Fettman unearthed, neither Bruenn nor FDR's other doctors ever used the word cancer. Still, Lomazow and Fettman's research is of great importance."
