Correlation between radon levels and lung cancer mortality rates: experimental and theoretical problems
Radon is a radioactive gas and is present in most earth materials such as soil, stone, air, water and others. Comprehensive and scientifically rigorous studies found a low lung cancer mortality rate in high radon areas. It is opposite to the linear no-threshold hypothesis (LNTH), which is a popular theory in the field of radiation safety. The fact is explained by the theory of energy transfer ...

Low-dose irradiation for controlling prostate cancer
Prostate cancer is the second most commonly diagnosed cancer among North American men and the second leading cause of death in those aged 65 and over. The US Cancer Society recommends testing those over 50 years of age who are expected to live at least for 10 years, even though the ability of early detection to decrease prostate cancer mortality has not been demonstrated. A controversy exists ...

Total and cancer mortality of the residents living in a zone of weak technogenic radioactive contamination
Radioactive contamination of the floodplain of the Yenisei River with the wastes dumped by the Krasnoyarsk Mining and Chemical Combine (MCC) might cause external and internal irradiation of a large part of the rural population inhabiting the banks of the Yenisei. Contrary to official data, a few independent studies of the doses received by the exposed population showed that they were quite ...

Radiation prevents much cancer
Evidence reviewed here supports the concept that chronic exposure to ionising radiation can dramatically decrease cancer incidence and mortality. This evidence includes an inverse relationship between radiation levels and cancer induction and/or mortality in: over 200 million people in the USA; 200 million people in India; 10,000 residents of Taipei who live in cobalt-60 contaminated homes; high ...

Non-cancer disease mortality and risk analysis among medical X-ray workers in China
The non-cancer disease mortality (1950-1995) among 27 011 medical diagnostic X-ray workers was compared to that of 25 782 other medical specialists employed between 1950 and 1980 to provide evidence of human non-cancer disease death produced by protracted and fractionated exposure to ionising radiation and assess the resultant non-cancer disease death risk. The total non-cancer disease mortality ...

Absence of evidence for threshold departures from linear-quadratic curvature in the Japanese A-bomb cancer incidence and mortality data
The recently released data on cancer incidence and mortality in the Japanese A-bomb survivors are analysed using a variety of relative risk models which take account of errors in estimates of dose to assess the dose-response at low doses. If a relative risk model with a threshold (the dose-response being assumed linear above the threshold) is fitted to the solid cancer incidence or mortality ...

Re-examining the health effects of radiation and its protection
The health effects of radiation from atomic explosions in Japan were completely different from those due to radiation from the Co-60 contaminated apartments in Taiwan. The sudden exposure to acute radiation in extremely high doses killed Japanese people, and harmed the survivors in lower doses as shown by increased cancer mortality, especially the leukemia based on the LNT model. The chronic ...

Generating a robust prediction model for stage I lung adenocarcinoma recurrence after surgical resection
Abstract Lung cancer mortality remains high even after successful resection. Adjuvant treatment benefits stage II and III patients, but not stage I patients, and most studies fail to predict recurrence in stage I patients. Our study included 211 lung adenocarcinoma patients (stages I–IIIA; 81% stage I) who received curative resections at Taipei Veterans General Hospital between January ...

New Breast Imaging Technology: The Koning Difference
Revolutionizing breast cancer detection Breast cancer is the most diagnosed cancer in women in the United States and the second leading cause of cancer death in American women.1 It is also treatable if detected early enough. While there are various cancer detection modalities available, current breast imaging devices fail to expose as much as 35% of breast cancers and that number increases to ...

Methylation Markers of Pancreatic Cancer categorization and prognosis evaluation
Background Pancreatic cancer is one of the highest mortality rate cancers worldwide with 5-year relative survival of 10.8%. Lack of screening methods for early-stage detection as well as proper patient sub-characterization, make it a fatal cancer due to poor diagnoses and insufficient treatment. Methylation flags are kept on tumorigenesis, akin to the tissue-specific traces that are acquired and ...

Researchers highlight the impact of COVID 19 pandemic on patients with cancer
New collaborative research from Queen’s University Belfast, the University of Split, Croatia and King’s College London has shown that the response to the outbreak of the coronavirus disease 2019 (COVID-19) is significantly affecting the treatment and care of patients with cancer. The research, recently published in the European Journal of Cancer, highlights how the repurposing of ...

Expression Genomics of Cervical Cancer: Molecular Classification and Prediction of Radiotherapy Response by DNA Microarray
Purpose The incidence and mortality rates of cervical cancer are declining in the United States; however, worldwide, cervical cancer is still one of the leading causes of death in women, second only to breast cancer. This disparity is at least partially explained by the absence of or comparatively ineffective screening programs in the developing world. Recent advances in expression genomics have ...
