Did you know that low cholesterol may be a sign of undiagnosed cancer?

Reports Reuters:

Low total cholesterol may be a sign of cancer rather than a cause, as some researchers have suggested, and men who have low cholesterol actually have a lower risk of developing high-risk prostate cancer, two teams reported on Tuesday.

Both studies, reported in the journal Cancer Epidemiology, Biomarkers & Prevention, shed new light on the role of cholesterol and cancer.

For years, researchers had noticed that people who have lower total cholesterol — a combination of both low-density lipoprotein or LDL, the “bad” kind, and high-density lipoprotein or HDL, the “good” kind — appeared more likely to have certain types of cancers than other people.

That was worrisome because having low cholesterol, and particularly low levels of “bad” LDL cholesterol, has been shown to protect against heart attacks and strokes.

“Our study affirms that lower total cholesterol may be caused by undiagnosed cancer,” Dr. Demetrius Albanes, a senior investigator at the National Cancer Institute, part of the National Institutes of Health, said in a statement.
