Lithocholic acid, a bile acid produced in the liver, kills cells of breast, prostate and neuroblastoma cancers.
The discovery has been made by researchers from Concordia University, although their findings have so far been restricted only to laboratory tests. The next stages are experiments with laboratory mice and eventually in humans, they say.
The researchers discovered more than 20 chemicals in the body that help slow the ageing process, and the most effective was lithocholic acid. The acid interferes with the mitochondria, or energy stores, in a cancer cell, and stops it developing.
The researchers say that ageing and cancer seem to be linked.
