Strange links: How hayfever may have protective affect against cancer
The surprising connection between diseases
This week: Hayfever and cancer
HAYFEVER and asthma may protect against bowel cancer, according to a 2012 study of more than one million US residents.
Those with both conditions had a 17 per cent lower risk of dying from the disease, according to the American Association of Cancer Research. Eric Jacobs, strategic director of pharmacoepidemiology at the American Cancer Society, suggests the immune system in people with allergies may kill cancer cells with an allergic-reaction-like response.
Other studies linked eczema (which often coincides with allergies and asthma) with a lowered risk of skin cancer – the immune system is thought to provide the protection.
