Cancer link to Parkinson's - study

Press Association, February 16, 2009

People with a family history of skin cancer may be more vulnerable to Parkinson's disease, new research suggests.

A link between melanoma and Parkinson's was already suspected. Previous studies have shown that sufferers of Parkinson's disease have an increased risk of developing the cancer.

The new study showed individuals who had a family history of melanoma were nearly twice as likely to develop Parkinson's as those who did not.

Scientists looked at almost 157,000 people who had not shown any symptoms of Parkinson's. They were asked if any of their parents or siblings had been diagnosed with melanoma, a type of tumour that includes the deadliest form of skin cancer.

Researchers then traced their progress for a period of 14 to 20 years. During that time, 616 of the group were diagnosed with Parkinson's disease.

The findings will be presented at the American Academy of Neurology's 61st annual meeting in Seattle in the spring.

Study author Dr Xiang Gao, from Harvard University School of Public Health in Boston, said: "The results from this study suggest that melanoma and Parkinson's could share common genetic components. More research needs to be done to examine the relationship between these two diseases."

Parkinson's disease is characterised by muscle rigidity and tremors and affects about 10,000 people in the UK each year.

It is caused by the loss of brain cells that help co-ordinate movement.

An estimated 9,300 people in the UK are diagnosed with melanoma each year. The disease is curable if caught early but malignant melanoma can be highly dangerous.
