GREENSBORO — Researchers found more cases of pancreatic cancer than expected in residents who have lived near the White Street Landfill and a former dump site nearby, a state Department of Health and Human Services analysis shows.
The findings, released to the city this week, do not imply that the landfills caused the disease.
The city wants to bring state officials to Greensboro to explain the cancer analysis research.
“The facts are what they are, but you don’t know the cause and effect,” Deputy City Manager Bob Morgan said of the cancer analysis. “We really need to have the state come and explain the study to the council and to the community.”
The Guilford County Department of Public Health, which launched the research effort on behalf of the city, also studied birth weights and cancer-death data for people who lived immediately around the former dump site, called the E.H. Glass Landfill. They found no health risks to residents and said no further research was needed.
“Our conclusion is there is no increased risk to anybody living in proximity to that landfill,” said Mark Smith, staff epidemiologist for Guilford County.
The White Street Landfill, which is closed to household trash, has been the source of intense public debate over the last few months, after City Council members discussed whether it would be more cost-effective to reopen it.
Residents around the landfill have fought that suggestion.
The research was completed at the urging of City Councilwoman Trudy Wade, who asked whether there was evidence to support the residents’ concerns that exposure to landfills caused health problems.
Wade asked whether the Glass Landfill, located west of the White Street Landfill on Nealtown Road, might be contributing to cancer in the area.
The Glass Landfill was operated in the 1960s and ’70s, according to state records. What kind of garbage was dumped there is not well-known, although some records indicate the Vicks Co. used the landfill to dispose of NyQuil and other returned products.
The state researchers looked at cancer registry data since 1990 from residents who lived in the area around both landfills, primarily to the northeast, where residents could potentially come into contact with contaminated water or air.
Researchers found 27 incidences of pancreatic cancer, about twice as many cases as they expected.
They also found 13 cases — more than they expected — of multiple myeloma, a cancer of the blood plasma cells. But the number of cases was so small that researches did not draw any conclusion from them.
The researchers point out that the study does not prove exposure to the landfill caused any health problems.
“It’s easy to blame the environment, but the environment is really the cause of a very small number of cancers,” said Douglas Campbell, head of the Occupational & Environmental Epidemiology Branch of he N.C. Division of Public Health.
State and county investigators have not found any toxin that residents in the area are drinking or inhaling from the landfills. Further research would be needed to prove such a link, according to the cancer analysis.
And other things — like genetic risk factors for certain diseases or lifestyle choices such as smoking — can affect whether a person develops a disease, the experts said.
The higher number of pancreatic cancer cases could be explained by the demographics of the study area, said Smith, who did some of the county’s research on the Glass Landfill.
Pancreatic cancer is more prevalent in African Americans, and African Americans make up about half the residents included in the study area.
“That in itself could explain the higher level,” Smith said.
