Cancer alludes to over 277 distinct malignancies in its broadest sense. The pathogenesis of these cancers has uncovered various cancer stages in which gene mutations will play a key role. Abnormal multiplication of cells occurs due to these mutations in the genes. Environmental factors are thought to be responsible for 70-90 percent of all carcinomas. A tissue with a large number of stem cells is considered a sign of developing carcinoma in that particular tissue. The characterization of tumors is done by obtaining stem cell-like properties, which shows evidence that a stem cell-like population endures and proliferates tumors. Finding people who appear healthy in a community, have a disease in its earliest stages, or are more likely to get a condition is known as screening in the healthcare industry. An early diagnosis of an illness, which can subsequently be efficiently treated at an early stage, results in a decreased diseasespecific or overall fatality. This is the aim of a screening test. In this, the effects of different environmental exposures that may impair functions of stem cells related to carcinogenesis. Several cancer screening methods were identified in the mid of the 20th century. In this article, we have discussed the effectiveness and evaluation of the screening of cancer programs in different countries. This article also established the estimated number of deaths and new cases observed worldwide in 2018. In this review, we have also established the molecular perspectives of cancer. The economic constraints related to the screening problems are also discussed.
