A hundred years ago, cancer was not common but for the last couple of decades number of incidence has been rising alarmingly, probably due to our changing life style and habits. The situation is alarming since every fourth person is having a lifetime risk of cancer. India registers more than eleven lakh new cases. We are constantly exposed to a variety of cancer causing agents known as carcinogens in the food we eat, in the water we drink and in the air we breathe. One single meal may contain danger of carcinogen in the form of residues of particles or insecticides. Exposure to electromagnetic radiation emitted by cell phone, computer and other electrical appliances can cause cancer. Like wise there is a long list of chemical, physical, biological and geographical carcinogens1. The total number of cancer deaths by the country is collected annually and are made available by the World Health Organization (WHO). About 12.7 million cancer cases and 7.6 million cancer deaths are estimated to have occurred in 2008 worldwide, with 56% of the cases and 64% of the deaths in the economically developing world. Breast cancer in females and lung cancer in males are the most frequently diagnosed cancers and the leading cause of cancer death for each sex in both economically developed and developing countries, except lung cancer is preceded by prostate cancer as the most frequent cancer among males in economically developed countries. Cancer affects everyone in different ways, and everyone has the power to take action to reduce the impact of the disease on individuals, families and communities. The global cancer epidemic is enormous and is set to rise. Currently 8.2 million people die from cancer worldwide every year, out of which 4 million are premature deaths. Over the next ten years cancer deaths are projected to increase to over 14 million per year2. Despite significant advances in the understanding of cancer, including causes, prevention, early detection, diagnostic tools, prognostic indications, treatment, and symptoms management, many people still associate cancer with pain and death. World cancer research fund international estimates that for the 13 most common cancers, about 31% of cases in the United States are preventable through a healthy diet, being physically active and maintaining a healthy weight3. Tobacco is the most important risk factor for oral cavity and oropharyngeal cancer. Mouth cancer is largely a lifestyle disease, meaning that the majority of cases are related to tobacco use. Approximately 90% of people with mouth cancer are tobacco users. People, who stop using tobacco, even after many years of use, can greatly reduce their risk of all smoking related illnesses, including mouth cancer.
