Abstract

The Estimated numbers of new cancer cases and deaths in 2020 will be an estimated. 1.8 million new cancer cases diagnosed and 606,520 cancer deaths in the United States and there were 17 million new cases of cancer worldwide in 2018 [1]. The four most common cancers occurring worldwide are lung, female breast, bowel and prostate. A person’s risk of developing cancer depends on different factors, including age, genetics, and exposure to some potentially known carcinogens and those which are believed to be carcinogenic. Some avoidable lifestyle factors including smoking can increase cancer risk. However, cancer risk factors are similar worldwide. Insufficient exercise, alcohol, imbalanced diet, and obesity, and various infections account for a considerable proportion of cancers worldwide. Prevalence of any one of the risk factors varies in different ethnic groups and can vary by region and country, which contributes to variation of cancer incidence rates of the common types of cancer worldwide.
