✦ Synopsis

Analysis of long-term survival depending on the season of cancer diagnosis 1 found mortality reduction among breast cancer patients in England that were diagnosed in the autumn. This could indicate a seasonally protective mecha-nism, possibly due to the higher vitamin D status in the autumn.

We investigate whether long-term survival in the United States is affected by the season of diagnosis of breast cancer. Table 1.
