Parkinson’s disease - the hardship at old age

Cancer suppression at old age.

Increased age is regularly linked with heightened cancer risk, but recent research suggests a flattening around age 80. We report that, independent of cancer site or time period, most incidence rates decrease in the more elderly and drop to or toward zero near the ceiling of human life span. For all major organ sites, male and female, we use 1979 to 2003 Surveillance, Epidemiology, and End Resu...

Heart disease in old age.

In a post-mortem analysis of 1,500 patients, aged 70 years or more, heart disease and malignancy were the two major causes of death. Coronary disease was exceedingly prevalent, almost one in five being subject to this form of heart disease, and 13% dying from its effects. The levelling of the sex ratio in coronary disease in the aged was a striking feature. The clinical manifestations of corona...

Age Distribution of Cancer: The Incidence Turnover at Old Age

In recent years data on cancer incidence in the USA, the Netherlands, and in Hong Kong indicate a flattening and perhaps a turnover at advanced age, but no model has been successful in fitting this data and thus providing clues to the underlying biology. In this work we assume these data are reliable and free from bias. We find that a Beta distribution fits SEER age-specific cancer incidence da...
