Antitumor activities of mastic oil from P. lentiscus were studied in a xenograftmouse with Lewis lung carcinoma tumor model. The oil was administrated intraperitoneally.The growth inhibition tumor was moderate without toxicity. Themechanism of action is related to an increased apoptosis, a reduced neovascularization,and an inhibition of chemokine expression (Magkouta et al. 2009).
