In the study, 1100 patients with breast cancer, researchers from the Institute Robert-Sauve Occupational Health Research in Montreal found that certain chemicals and harmful substances released into the atmosphere in special industries, significantly increase the risk of mammary tumors . For example, nylon fibers, this risk doubles.
If the cancer cells in a woman's body react to estrogen, but not to progesterone, the danger of contamination breast cancer It grows at least twice every 10 years. These are the industries where workers are exposed to mono-aromatic hydrocarbons, a by-product of crude oil as well as acrylic and viscose fibers.
But the danger may be even greater! If cancer cells and women respond to estrogen and progesterone, after regular contact with polycyclic aromatic hydrocarbons (which are in various oil products) the risk of cancer grows three times (!). This is especially true of women who are faced with harmful substances to 36 years.
Study author Dr. Frans Labresh believes that the data obtained confirm the theory that breast tissue of women under the age of 40 is more sensitive to the effects of harmful chemicals.
However, a number of British experts suggested that these findings may be the result of chance. To confirm their need for new research.
