Sneezes, rashes, fever – allergies are usually considered to be more of a nuisance. but some recent studies change this perception.
Allergies have been long appreciated by researchers as a sign of strong and vigilant immune system. Most studies, carried on in the past two decades, have shown that people with common allergies like hay fever, asthma and eczema do run a slightly decreased risk of some cancers. However, this is not yet clear as to why it happens.
In a report published online in July in BMJ Open, researchers have presented a study that was being conducted 1984 to 2008, on around 17,000 adults. Those who contact allergies when in proximity of metals, poison ivy, hair dyes or other chemicals develop skin irritation. After monitoring the subjects’ long-term health and cross-checking their records against a cancer registry, the scientists found that who contact skin allergies are less likely to have breast cancer and skin cancer.
Studies suggest having allergies may lower the risk of some cancers, but more research is needed.
