Manitoba's Chief Public Health Officer has decided to investigate the concerns of Lynn Lake, Man. residents that old mining waste in the town is elevating their chances of getting cancer. 

For years people living in the northern Manitoba town have believed they had a higher than average chance of getting cancer. 

After a CBC News investigation last week that looked at cancer rates in Lynn Lake, public health officials got involved.

Waste from nickel operations was used as back-fill for much of the town, including a subdivision and the local hospital. 

CBC News spoke with longtime residents Pat and Neil Campbell, who live on Eldon Avenue in town. They estimate at least 30 people within a two-block area have been diagnosed with some form of cancer.

People who feel living in the town may have affected their health are asked to contact the province's public health department directly.
