The impact of Medicare on early cancer detection in the elderly.

In an analysis of 23 sex-specific tumors in the Connecticut Tumor Registry, only seven tumors showed more than a 20 per cent increase in the ratio of localized tumors detected post-Medicare (1967-75) versus ante-Medicare (1960-65) in the 65-75 year age group compared to the 60-64 year age group. Of these seven, the information was more convincing for lung cancer in males. Overall, however, Medicare had little if any impact on early tumor diagnosis in the elderly.
