A recent study published in The Prostate by Dr. Lagunova and colleagues suggests that the season of prostate cancer diagnosis may be linked with survival. The study showed that men diagnosed with prostate cancer in the summer and autumn have better survival.Vitamin D deficiency has been linked to higher prostate cancer mortality in previous studies. The authors put forth a theory that levels of calcidiol, an intermediate metabolite of Vitamin D, are higher during the summer and autumn and therefore may impact prostate cancer incidence and outcome. The researchers divided Norway into three areas based on sun exposure and documented Vitamin D intake.
The best prognosis for prostate cancer patients were for those diagnosed in the summer and autumn, defined from June to November.
