Volume 6(1) 1000e130 J Cancer Sci Ther ISSN: 1948-5956 JCST, an open access journal Cancer has existed probably since the dawn of civilization; however, it came into prominence during 19th century. There could be many reasons because of which cancer remained out of public attention. Age is one of the strongest causal factors in case of most of the cancers, and symptoms of cancer manifests or become more prominent in old age; therefore, it was regarded as just another old age related health complexity. Before 19th century, there were other diseases like cholera, plague etc., which took lives of millions of people around the world, because of absence of proper medical facility [1]. Life expectancy in those times was much less than that of today’s because of absence of proper medical facility, and other factors like war. Simplicity in life style, food habits, was also responsible for keeping a check on cancer related incidences. In the last couple of centuries, we have witnessed tremendous progress in medical science and healthcare, because of which average life expectancy has increased. Owing to increased life expectancy, there are more chances for age related malignancies like cancer to appear in the life time of an individual. The so called ‘modern life’ is often accompanied by various vices like processed food, sedentary life style, smoking, drinking etc. which are known to trigger cancer initiation [2].
