News report: Pancreatic cancer risk linked to weak sunlight
You may have seen reported in the news yesterday a story about pancreatic cancer risk being linked to weak sunlight.
“Writing in the April 30 online issue of the Journal of Steroid Biochemistry and Molecular Biology, researchers at University of California San Diego School of Medicine report pancreatic cancer rates are highest in countries with the least amount of sunlight. Low sunlight levels were due to a combination of heavy cloud cover and high latitude.
Researchers studied data from 107 countries, taking into account international differences and possible confounders, such as alcohol consumption, obesity and smoking.
This is an interesting study which adds to a body of research that looks at whether vitamin D deficiency may be related to a risk of pancreatic cancer. There have been studies which suggest higher levels of Vitamin D decrease risk, but there have also been those that show it may increase risk. There is definitely a need for more information on potential ways to reduce the risk of/prevent pancreatic cancer so it is thought-provoking to see further information on this.
Vitamin D is found in a small number of foods, such as oily fish, eggs, fortified fat spreads, fortified breakfast cereals and some powdered milks. You can also get vitamin D from exposure to sunlight, but it is important to remember that this research should be considered alongside advice for other cancers and the dangers of exposure to sunlight e.g. skin cancers.
