Researchers from Norway and Oregon Health and Science University have found that the season in which a man is diagnosed with prostate cancer may affect his survival.
The study found that men diagnosed in the summer and autumn months have a better chance of survival than if they were diagnosed in the spring and winter. The scientists say this may be linked to vitamin D that can be provided by sunlight.
Although the study was conducted in Norway, Oregonians are also susceptible to vitamin D deficiency in the winter.
Prostate cancer is the most common type of cancer found in American men outside of skin cancer.
