The scientific side of steroid use and abuseIs there a cancer cluster in baseball? But the news also raised a deeper kind of worry. Glioblastoma do anabolic steroids cause brain cancer a rare cancer, but it does seem to turn up with disturbing frequency in the MLB. Is there something about baseball—which involves calcium propionate kemira near the ferocious contact that football does but does have its share of collisions—that is causing the trauma that leads to the disease? Daulton, Oates and Carter all played catcher, which is the most physical of all of the positions in the diamond.

With the passing of Darren Daulton to brain cancer , fans will remember he was not the only Phillie of the Veterans Stadium era with the disease.
When he was diagnosed in , we ran the numbers and talked to experts. Was it a coincidence? All four played for the Phillies at Veterans Stadium, and all four developed brain cancer.
Is there a connection? The rate of brain cancers in team members from that era appears to be about three times the rate in the adult male population, according to an Inquirer analysis that was reviewed by a University of Pennsylvania epidemiologist.
And that elevated rate of brain cancer is statistically significant, though the analysis had certain limitations and the pattern easily could be due to chance, said Penn's Timothy R. Brain cancer can be caused by radiation and by certain rare genetic mutations, but the evidence for most other potential causes is unclear. Studies suggest that estrogen and related hormones can protect against the development of brain cancer in women, said Geoffrey C.
So it would be reasonable to examine whether anabolic steroids, which are related to those hormones, could play some role in brain cancer, Rebbeck said. Occupational scientists also have looked to see whether any health issues are associated with synthetic turf, as some older kinds contained small amounts of contaminants such as lead, but there is no known link between the artificial surfaces and brain cancer.
The Inquirer identified men who played for the Phillies between and , and tallied the number of years they have been alive since then. For those who had died, the dates of death were taken from baseball-almanac. The analysis then compared the rate of Phillies' brain cancers over that period with the rate of similar cancers in the adult male population, using data from the U.
The national rate was 9. The national count included various kinds of glioma, such as glioblastoma - the aggressive form of cancer that struck all four former Phillies. With Rebbeck's assistance, The Inquirer then calculated that this 3. In lay terms, that means if one were somehow able to replay that year period times, you would expect the players' brain cancer rate to be 2. But Rebbeck cautioned that the analysis required making certain assumptions that could substantially change the outcome.
For example, the population of Phillies from to was not adjusted for age. The rate of brain cancer varies with age, so when comparing populations, it is important that they have the same distribution of people in various age groups. The Phillies in the analysis range in age from their 30s to their 70s whereas the national population number includes men above and below that. Furthermore, the nationwide brain cancer number for the year period was based on cases counted in to A better approach would be to use the exact number of adult male brain cancers for each year from to , as the cancer rate has declined slightly over time.
Datto, a longtime friend of Daulton's, said the catcher and his family welcomed the analysis but felt it was premature to comment on any possible connection between cancer and baseball. Two other teams - the New York Yankees and the Kansas City Royals - each have had at least three former players with brain cancer in the same era.
As with the Phillies, the numbers are small enough that it could be bad luck. To add another wrinkle, a sportswriter who covered the Phillies also died of brain cancer. Mike Ferretti, the Phillies beat writer for the Bucks County Courier Times in the s and early s, died of glioma in September Jane Ferretti, Mike's mother, said she immediately thought of her son's case upon hearing about Daulton, and wondered whether there might be some connection.
Vukovich played for the Phillies from to and from to , and he was a team coach from to He died in at age McGraw, best known for striking out the last batter to seal the team's championship in , pitched for the team from to He died in , also at age Johnny Oates played for the Phillies just two years, in and , spending most of his career on other teams.
He died of brain cancer the same year as McGraw, at age Still another former Phillie, pitcher Ken Brett, reportedly died of brain cancer. But family members did not immediately respond to a query about the type of tumor, so he was left out of the Inquirer analysis.
Brett pitched here for just one year, One could argue that he - along with Oates, a Phillie for less than two seasons - should not be part of the Phillies' cancer toll because they played for the team for brief periods.
If you took them out of the equation, that would lower the team's brain cancer rate. But then you also would have to remove all the short-duration players who did not get brain cancer. Of the Phillies, played for one season or less.
If you removed them from the analysis, the team's brain cancer rate would be higher. Contact Tom Avril at or tavril phillynews. Search Search Search Search icon. Opinion Blogs Columnists Letters.
