CAMERON, Mo. -- A state investigation into a rise in brain tumor cases around Cameron found no central cause, a state epidemiologist said Thursday.
Sarah Patrick told about 150 people at a meeting in Cameron that the number of brain tumor cases in a four-county area around the northwest Missouri town is not statistically higher than the numbers throughout the state.
Brain tumor cases are increasing throughout Missouri and the nation, and Cameron is part of that trend, Patrick said.
Patrick said about 70 people in Caldwell, Clinton, Daviess and DeKalb counties met the scientific criteria used by the state during its cancer inquiry. That included 24 with benign tumors since Jan. 1, 2004, and 46 with malignant tumors in the last 11 1/2 years.
"If your perception is that you know more people with brain tumors, and it is changing over time, that perception is right," Patrick said. "That is true nationally, too. Brain tumor reports are going up."
The results came after a five-month state inquiry that began when people who had either been diagnosed or had a relative diagnosed with brain tumors contacted health officials and the news media about what they considered an abnormally high number of brain tumors in and around the northwest Missouri town of about 6,500.
The state expanded the investigation to include the four counties, with a total population of about 50,000.
Patrick also said the number of brain tumor cases in the four-county area was ranked 10th behind several other types, with lung cancer at the top of the list. Statewide, brain tumor reports ranked sixth.
The findings drew immediate skepticism from some Cameron residents who have been affected by a brain tumor diagnosis.
