Cancer is the leading cause of morbidity and mortality worldwide and one in every seven deaths is due to cancer. It has the worst incidence and mortality statistics. According to the International Agency for Research on Cancer (IARC), an estimated 14.1 million new cases of cancer occur with mortality of 8.2 million worldwide. There are more than 100 types of cancer. Here, in this article, statistical insight is shed on few of the major cancers viz. lung cancer, breast cancer, colorectal cancer and prostate cancer.
- Lung cancer is one of the wide spread cancer, World Health Organization (WHO) has reported that there were an estimated 1.8 million new cases for lung cancer in 2012 and 1.59 million estimated deaths globally. As reported by the American Cancer Society, the estimated new cases for lung cancer in 2017 would be around 222,500 and the estimated mortality would be around 155,870 in US alone. There are approximately 52 drugs approved for the treatment of Non-Small Cell Lung Cancer, showing an increased effort towards treating lung cancer.
- Breast Cancer is also one of the most common cancers, and WHO has reported that there were estimated 1.67 million new cases in 2012 and 522,000 million estimated deaths globally. As reported by the American Cancer Society, the estimated new cases for invasive breast cancer and in situ breast cancer in 2017 would be around 252,710 and 63,410 respectively and the estimated mortality would be around 40,610 in US alone. There are approximately 63 drugs approved for the treatment of breast cancer, and a vast pipeline aiming to decrease the mortality associated with this type.
- The statistics of WHO in terms of colorectal cancer show that globally there were around 1.36 million new cases for colorectal cancer in 2012 and 694,000 estimated deaths. As reported by the American Cancer Society, the estimated new cases in 2014 were around 136,830 and the estimated mortality was around 50,310 in US alone.
- Prostate Cancer has also become a concern in terms of mortality and morbidity, with WHO reporting that globally there would be estimated 1.09 million new cases for prostate cancer in 2012 and 307,000 estimated deaths. The American Cancer Society also estimates new cases for colorectal cancer in 2017 to be around 161,360 and the estimated mortality to be around 26,730 in US alone. There are approximately 28 drugs approved for the treatment of prostate cancer, showing immense R&D interest.
