ABSTRACT
134Cancer is a disordered condition between cell proliferation and cell death. Factors have been identified that are involved in the process of invasion and metastasis of tumors and cause resistance to treatment. A huge effort has been made in the past 20 years to provide the data to design more effective, individualized, and target-oriented advance treatment strategies. Regardless of the development of various new treatment regimes, cancer still causes a large number of deaths in the United States, according to the American Cancer Society [1]. It is now concluded by various studies that lifestyle is a major factor behind 90%–95% of all cancers, whereas faulty genes are involved in 5%–10%. A number of research studies have shown that inclusion of foods rich in fruits and vegetables decreased the occurrence of cancer. As per the studies, nutrition could prevent a large number of cancer deaths and a great likelihood of certain cancers could be avoided by dietary modifications [2]. The roles of dietary agents and lifestyle have already been studied for various cancers such as colorectal, skin, prostate, breast, ovarian, cervixal, vaginal, lung, and gastrointestinal tract [4].
