4 Your Health: IQ effects life span; accuracy of diagnosing skin cancers

Posted: Updated:

Tucson- A new study is raising concern about the accuracy of diagnosing melanoma.

Researchers, at the University Of Washington, asked nearly 200 pathologists to interpret the same set of skin biopsy cases.

The doctors were mostly accurate when diagnosing lesions that were clearly mild or malignant. But they were much less consistent in cases that fell in the middle of the spectrum. 

Overall 83 percent of biopsies were interpreted correctly.

High IQ equals longer life

Having a high IQ has many benefits but new research suggests it may play a role in how long you live.

A Scottish study of over 65,000 men and women found childhood intelligence was linked to a lower risk of death until the age of 79.

IQ had the most significant impact on deaths from respiratory disease, heart disease, stroke and smoking-related cancers. High childhood IQ was also associated with a lower risk of dying from injury, digestive disease and dementia.
