Low levels of two commonly measured liver enzymes may be associated with a higher likelihood of early-onset colorectal cancer in adults under 45, according to an Epic Research analysis published Wednesday.
Researchers analyzed health data from more than 11,000 U.S. adults aged 18 to 44. Those with AST levels below 14 units per liter had a 65% higher likelihood of being diagnosed with colorectal cancer, while those with similarly low ALT levels had a 68% higher likelihood.
However, experts caution that the findings do not establish low enzyme levels as a cause or definitive predictor of cancer.
Dr. Daniel Sussman of the University of Miami said the levels are generally considered normal and should not change current screening recommendations. Further research is needed to determine whether the findings apply more broadly.
