A recent study done by a group of researchers at INRS-Institute Armand-Frappier, the Research Centre of the Centre hospitalier de l"Université de Montréal, and McGill University, has come up with a finding which stated the exposure levels experienced at a workplace and the threats involved in developing of cancer, during a period of August 1979 and March 1986.

The study included 3,300 men, aged between 35 and 70 years who were having cancers at one of the Montreal's 18 hospitals, and at the same time have a control group of 512 people who have are normal.

Professor Marie-Claude Rousseau of the INRS-Institut Armand-Frappier, one of the key members of the study claimed that "Asthma and eczema are allergies brought about by a hyper-reactive immune system - a state which might have enabled abnormal cells to have been eliminated more efficiently, thereby reducing the risk of cancer."

The study however fails to state any factors linked with asthma and eczema that could be held responsible for lowering the risk involved in cancer. Rather it offers a new perspective altogether that states insights into molecular and immunological mechanisms that are employed in immune stimulation, an aid to curb the cancer.
