This study employs the dichotomous choice contingent valuation method to estimate the Value of a Statistical Life (VSL) and the Value per Statistical Case (VSCC) of cancer risk. In contrast to the previous studies, which presented the mortality risk probability directly, the study uses conditional probability, which combines the chance of getting cancer and dying from it. In addition, the study examines the impact of variables that may affect willingness to pay for reducing the risk of death from cancer and getting cancer, such as the impact on daily life and pain levels associated with cancer. The results indicate that the estimated cancer VSL ranges from approximately 952 million won to 3.359 billion won, while the VSCC is estimated to be between about 0.42 billion won and 2.72 billion won. The study finds a significant difference in the VSL depending on whether the reduction in mortality risk is from a decrease in the chance of getting cancer or a decrease in the chance of dying from cancer. However, the effect of impacts on daily activities and pain on willingness to pay is inconclusive.

From the concepts of cellular pathology and of exfoliative cytology, as elucidated by Virchow and Papanicolaou respectively in the late 19th and early 20th century, have evolved the primary methods for the diagnosis of cancer today. From Papanicolaou's concept of exfoliative cytology developed fine needle aspiration biopsy in the early 1960's, this has become a major diagnostic procedure and has contributed to a significant reduction in open biopsies and, therefore, to medical cost-effectiveness immunobiochemical techniques provided us with a supplement to cancer diagnosis in the 1980's. The immunoperoxidase method, using monoclonal antibodies, is applied primarily as an ancillary measure to elucidate the nature of cancers The availability of specific monoclonal antibodies has greatly facilitated the identification of cell products or surface markers. For example, antibodies directed against intermediate filaments have proved to be of value in determining the histogenesis oi poorly differentiated neoplasms. Tumor markers may serve as biochemical indicators of the presence of a neoplasm. They can be detected In plasma and other body fluids. Their concentration can be applied as a diagnostic test, for monitoring the clinical course of known cancer, and as a screening measure to detect certain cancers in a population at risk. Flow cytometry is a useful tool for distinguishing several cell characteristics, such as the immunophenotype of leukemia-lymphoma cells, the DNA content of neoplastic cells, and cell proliferation rate. Molecular biologic techniques provided a giant step for the management of cancer patients encompassing diagnosis, prognostic evaluation, and therapy. Nucleic acid hybridization techniques are utilized as Southern, Northern, and dot blots and in situ hybridization. Molecular biology and its techniques may bring a blight new horizon for understanding cancer biology and in designing therapy on the basis of gene manipulation.
