Because these receptors exist all over the physical body, researchers wondered if terpenes could have an impact on cancers cells. To test this theory, Dr. Hatt and his team utilized a cellular style of hepatocellular carcinoma, the most typical kind of liver tumor; about four in five cancers that start in the liver are hepatocellular carcinoma.
