While it’s been known for quite some time that increased exposure to ultraviolet (UV) rays increases a person’s chances of developing skin cancer, no link has ever been found between precipitation and cancer risk, until now…
A new study has revealed a potential link between living in cold, wet regions and increased cancer prevalence.
The study, the results of which are published in the journal Environmental Engineering Science, is the first in the United States to check if a relationship exists between cancer rates, precipitation, and climate zone.
To find out, the scientists collated data on breast cancer, colorectal cancer, lung cancer, ovarian cancer, and prostate cancer. They also used county-level data relating to cancer incidence, climate, and demographics.
Having adjusted for age, gender, ethnicity, income level, population age, and diversity, the scientists identified a strong association between increased precipitation and an increase in incidence of all cancers.
While it is important to note that not all cancer types were included in the analysis, the findings are still significant and strongly suggest climate zone is a risk factor for many cancers.
