Researchers have found that immune system gets boosted in people who are prone to seasonal allergies and it also helps to reduce the risk of brain cancer.
"It appears that allergies and asthma rev up the immune system," said Michael Scheurer, the study's lead author. "They seem to produce enough inflammation in the brain to keep immune system cells active and working to prevent cancer from beginning to develop.", reports foodconsumer.org.
The study looked at more than 800 brain tumor patients and a similar number of healthy adults from Harris County and the San Francisco area. More than 300 people had glioblastoma, the most aggressive and lethal type of brain tumor, more than 100 had mid-grade brain tumors and more than 150 had low-grade gliomas.
Individuals with a history of allergies and asthma had a 35 percent reduced risk of developing glioblastoma, a 51 percent reduced risk of mid-range tumors and a 36 percent reduced risk of low-grade gliomas, the Houston Chronicle reported.
The study was presented Sunday at the annual meeting of the American Association for Cancer Research in Washington.
