**7. Tocotrienols as chemopreventive and chemotherapeutic agents for various cancers**

The anticarcinogenic potential of tocotrienols was first acknowledged in 1985, in which the a-tocotrienol isomer had been shown to lengthen the age of rats afflicted with tumour [3]. Subsequently, numerous studies have been performed to highlight the postulated anti-cancer properties of tocotrienols in breast, colorectal, liver, lung, pancreas, prostate and stomach carcinomas. The following paragraphs cover the details of various studies performed using tocotrienols concerning cancer chemoprevention and management (**Table 1**).
