By what month in 2015 did President Carter announce scans showed no evidence of further cancer growth?

Answer

December 2015

The efficacy of the new immunotherapy regimen was rapidly demonstrated in President Carter's case. By early December of 2015, just months after the initial diagnosis was publicized in August, President Carter was able to announce publicly that his medical scans indicated no remaining evidence of cancer progression. This rapid response—shifting from a prognosis potentially measured in months to achieving clear scans within four months—provided a stark contrast to older cancer protocols and demonstrated the speed at which modern combination therapy involving immune checkpoint inhibitors could be effective.
