- 23. RECENT STUDIES • Lifestyle changes reduce the risk of prostate cancer( published in the journal Nutrition and Cancer, was carried out by researchers at UCLA's Jonsson Comprehensive Cancer Center (JCCC).) • Researchers Aiming To Suppress Therapy Resistance In Brain Cancer (http://www.medicalnewstoday.com/releases/262571.php) • Fish Oils Reduce Risk Of Breast Cancer (http://www.medicalnewstoday.com/articles/262612.php)
- 24. Life style changes reduce the risk of prostate cancer (Nutrition and Cancer" Lenore Arab, PhD, et al. Nutrition and Cancer Jun-2013) • Focuses on 8 new lifestyle recommendation by WCRF • Encouraged physical activity and consumption of food low in caloric density(under 125kcal/100 grams of food) • who followed less than 4 recommendation at higher risk(38%)
- 25. Research aiming to suppress therapy resistance in brain cancer (Helmholtz Association of German Research Centres. Medical News Today. MediLexicon, Intl., 29 Jun. 2013. Web) • Gliomas are malignant brain tumors, treatment combines radiotherapy with anticancer drug temozolomide • Some cases shows resistance , DNA repair mechanism aided by NAD+ molecule • QRTP enzyme break down quinolinic acid to NAD+ molecule • Agent directed against enzyme help suppress therapy resistance in brain
- 26. Fish oil reduces the risk of breast cancer (Nordqvist, Joseph. "Fish Oils Reduce Risk Of Breast Cancer." Medical News Today. MediLexicon, Intl., 28 Jun. 2013. Web.) • Links fish,n-3PUFA intake and risk of breast cancer • Marine n-3PUFA intake associated with 14% reduced risk of breast cancer • For every 0.1g/day increase in consumption ,risk reduced by 5%
- 27. CONCLUSION • • • • Increase in the no: of cancer patients every year Factors responsible should be controlled Create awareness about cancer and its prevention Careful about diet and lifestyle
