St. Clair Co. officials expand look into cancers

May 13, 2011

MARINE CITY, Mich. (AP) - Public health officials in St. Clair County are expanding their investigation into whether environmental or other factors could be responsible for a rare form of kidney cancer diagnosed in children in the Marine City area.

The investigation started this year looking into five cases of Wilms' tumor since 2007 in southeastern St. Clair County. The Times Herald of Port Huron reported Thursday that eight cases now are included, including two in the Port Huron area and one in Richmond.

Officials say another case in the St. Clair Shores area isn't being considered because it's too far away.

Marine City, which is located about 40 miles northeast of Detroit, has industrial plants and is about 10 miles from petrochemical plants in Sarnia, Ontario. But health officials say there's no established link.
