Swedish doctors use cold to suppress the growth of cancerous tumors

Researchers at Karolinska University figured outthat continuous 20-day exposure to a temperature regime of four degrees below zero inhibits tumor growth and improves the survival of mice with five different types of cancer. The work of Swedish scientists has shown its effectiveness for humans.

The authors of the study suggested that low temperatures activated the brown adipose tissue of mice. She began to burn energy instead of storing it. The process led to a nutritional deficiency of the tumors.

To test the hypothesis, the researchers removed brown tissue from some mice and turned off the gene that makes brown fat heat in others. The cold had no effect on the tumors, which confirmed the role of brown fat.

The high glucose diet also failed to suppress the tumor. Therefore, this effect caused its deficiency

The scientists repeated the experiment on six volunteers. Two weeks for 3-6 hours they were exposed to low temperatures (16 degrees). They also activated stormy adipose tissue.

The researchers then exposed a person with Hodgkin’s lymphoma to -22 degrees for a week. His brown fat became active and the tumor began to consume less glucose.

The authors of the study stressed that cold can be bad for some chemotherapy drugs. Thinner advanced cancer patients will not get the same benefits as people with normal weight.
