From a 9-year-old article (2013):

At low temperatures the human body has a hard time. As the cold sets in, blood vessels constrict to maintain heat and some body parts – like fingers and toes – begin to suffer. Metabolism ramps up to fight the cold and shivering sets in. As these conditions continue, everything becomes sluggish as the cells of your body do not work as well. The body enters a state of thermal stress and only the most vital systems, like the brain, are left switched on.
Now, in a paper just published in the Proceedings of the National Academy of Sciences, Elizabeth Repasky at Roswell Park Cancer Institute in the US and colleagues suggest that cold has yet another disadvantage – it changes the way cancer cells grow and spread, at least in mice. This raises interesting questions about cancer therapies and many cancer studies, which tend to use mice as animal models...
It did not matter if mice had lived in the cold for a lifetime before they got cancer—a chilly exposure even after their cancer had become established still made their tumours grow more quickly...
The benefits of heat therapy for cancer may have been overlooked...

Chilly temperatures help cancers grow
