BACKGROUND Studies of atomic bomb survivors and medically exposed populations have demonstrated an increased risk of breast cancer associated with acute or protracted, intermediate-dose or high-dose, ionizing radiation; however, the risks associated with low-dose and low-dose-rate (protracted) exposures are less certain. METHODS The authors evaluated(More)
A retrospective case-control study of 713 male oral-cancer patients seen at Tata Memorial Hospital, Bombay, during 1980-1984 was undertaken to assess the association between chewing, smoking and alcohol habits. Male controls were chosen among those persons who attended the hospital during the same period and were diagnosed as free from cancer, benign tumour(More)
In laboratory studies, some antidepressants caused increased growth of mammary tumors. The relation of use of these drugs to the development of breast cancer was examined in a hospital-based case-control study. Information, including lifetime medication history, was collected by interview from 5,814 women with primary breast cancer diagnosed within the(More)
Objective: To investigate whether smoking, alcohol intake, female hormonal or anthropometric factors affect melanoma risk. Methods: Using Cox proportional hazards regression analyses, we analyzed 68,588 white subjects (79% female) from the US Radiologic Technologists (USRT) Study who were cancer-free (other than non-melanoma skin cancer) as of the first of(More)
BACKGROUND: A synthetic estrogen, diethylstilbestrol (DES), was widely prescribed to pregnant women during the 1950s and 1960s but was later discovered to be associated with an increased risk of clear-cell carcinoma of the vagina and cervix in female offspring. DES has not been linked to other cancers in female offspring, but studies of other prenatal(More)
BACKGROUND Cancer screening rates vary substantially by race and ethnicity. We applied the Peters-Belson approach, often used in wage discrimination studies, to analyze disparities in cancer screening rates between different groups using the 1998 National Health Interview Survey. METHODS A regression model predicting the probability of getting screened is(More)
As part of its strategy to identify cancer cases in a rural population, the cancer registry of Barshi, India, has developed a methodology which includes education of the population about likely symptoms of cancer, and motivation of symptomatic individuals to undergo medical investigation. Patients with cervical cancer from the registry area who attended(More)
BACKGROUND Workers exposed to low doses of radiation can provide information regarding cancer risks that are of public concern. However, characterizing risk at low doses requires large populations and ideally should include a large proportion of women, both of which rarely are available. METHODS Among 90305 radiologic technologists in the U.S. (77% women)(More)
OBJECTIVES Some studies of white women suggest that exercise reduces the incidence of breast cancer. There are no data on black women. We assessed the relationship between strenuous physical activity and prevalent breast cancer among participants in the Black Women's Health Study. METHODS Data on strenuous recreational physical activity at various ages(More)
A recent case-control study raised the hypothesis that acetaminophen use 1 day or more per week for at least 6 months reduces the risk of epithelial ovarian cancer. We assessed analgesic use in relation to epithelial ovarian cancer risk using data from our case-control surveillance study of medication use and cancer. Patients were interviewed in hospitals(More)
