chernobyl and cancer: The 1986 Chernobyl nuclear reactor accident has led to higher incidence of thyroid cancer in the Republic of Belarus, according to a report published by Martin Mahoney of Roswell Cancer Institute, Buffalo, USA in a recent issue of the International Journal of Epidemiology . Between 1970 and 2001, age-adjusted thyroid cancer incidence rates have increased from 0.4 per 100,000 to 3.5 per 100,000 among males and from 0.8 per 100,000 to 16.2 per 100,000 among females. The rise in thyroid cancer was found in both high exposure and low exposure areas.
