Prostatic cancer and social class.

Prostatic cancer and social class.

Over the last 30 years the death rate from prostatic cancer in Scotland has remained at about 17 per 100,000 in the age group 55-64 years, but at age 65-74 years the rate has increased from 64 in1930-32 to 106 per 100,000 in 1963, and in men aged 85 and over the rate has gone up from 86 to 476 per 100,000 in the same period (Registrar General for Scotland, 1963). This steep rise in mortality in...

Prostatic Hyperplasia and Social Class.

Formaldehyde, cancer, and social class.

Formaldehyde has been shown to cause nasal cancer in rats exposed by inhalation. Neoplasia did not develop at locations distant from sites of initial contact, a finding consistent with the chemical's high reactivity and rapid detoxification. The recently published report of the Consensus Workshop on Formaldehyde, however, drew particular attention to small excesses of malignant brain tumors and...

Tobacco smoking, cancer and social class.

Consumption of tobacco products, both by smoking and by other means, has long been causally connected with cancers of the lung, larynx, mouth and pharynx, oesophagus, bladder, and many other sites. Tobacco is the main specific contributor to total mortality in many developed countries and has become a major contributor in the developing countries as well. In most industrialized countries, preva...

Environmental exposure, social class, and cancer risk.

Exposure to a variety of environmental factors associated with cancer occurrence varies by social class. These factors include air pollutants (SO2, NO2, total suspended particulates, etc.), toxic waste hazards, and ionizing and other radiation. Heavy environmental pollution has been associated with an increased risk of some cancers and in particular lung cancer. There is limited evidence sugges...
