Can Allergies Cause Cancer?
If you have allergies, you may need to worry about more than just sniffles and sneezes. A new study indicates allergy sufferers may have a higher risk of developing cancer.
A seven-year study with more than 64,000 people done by the University of Washington Fred Hutchinson Cancer Research Center found individuals with allergies to plants, grass and trees had a slightly increased incidence of blood cancers.
Researchers said that although the allergies themselves don’t cause cancer, they believe it’s possible the inflammation that creates allergy symptoms could put your immune system into overdrive — and that could lead to blood cancers.
But there’s no need to panic. The risk increase is so slight that the study’s lead author, Dr. Mazyar Shadman, said there was “no need” for additional cancer screenings, adding only that he hopes further studies with allergy patients will “uncover the mechanism of blood cancers.”
