A study has found a connection between living in cold and wet regions with an increase in cancer prevalence. The findings are quite surprising.
Quite long ago scientists found out that increased exposure to ultraviolet (UV) rays from the sun increases the risk of skin cancer. However, a new study has revealed that precipitation and cooler climate are linked to an increase in cancer risk.
Earlier research found out that the amount of disparity between cancer cases and mortality rates is different in different regions of the US. The highest rates were clustered on the East Coast.
According to the authors of the recent study, these differences are “linked to racial, ethnic, behavioral, social, economic, and lifestyle factors.”
Also, environmental and occupational factors like air pollution and exposure to pesticides and solvents may play a part.
The new study was published in the Environmental Engineering Science journal. It investigated the potential role of precipitation and climate zone in causing cancer risk.
Climate zone has been defined by the authors as, “a variable that combines temperature and moisture level in a given area.”
They did not suggest that an increase in rainfall, temperature, and moisture directly cause cancer, however, they explained that explain how these climate factors “may increase the exposure to carcinogens by acting as carriers or increasing the natural biotic generation of carcinogens.”
The authors collected data on breast cancer, ovarian cancer, lung cancer, colorectal cancer, and prostate cancer to investigate their hypothesis. They accessed country-level data of cancer incidence, climate, and demographics.
