Snippet from the article:
Researchers in the US found of two groups of mice given the same cancer-inducing treatment, the group whose sleep was disrupted developed larger, more aggressive tumors than the well-rested mice.
In the journal Cancer Research, the team also reports how they found the immune system of the sleep-disrupted mice was less effective at fighting the early stages of cancer than the immune system of the well-rested mice.
Study director Prof. David Gozal says: “It’s not the tumor, it’s the immune system. Fragmented sleep changes how the immune system deals with cancer in ways that make the disease more aggressive.”

There was also a study published last year that linked sleep troubles with men’s prostate cancer risk. You can learn about that here.
