Second primary tumors after prostate carcinoma

The incidence of all neoplasms was reduced significantly in men diagnosed with prostate carcinoma. Selection of the population, under-registration of second primary tumors, and reduced surveillance in elderly men with prostate carcinoma may, at least in part, explain this reduction in risk. No excess risk was observed for the complex of urologic neoplasms nor for tobacco-related neoplasms. This finding would not support an association between cigarette smoking and prostate carcinoma.
