We have collected a number of popular and controversial versions and was asked to comment from the British oncologist Dr. Jodie Moffat of the organization Cancer Research UK.
The first version - cleaning products for the home
Theory - A recent study in the US found that women who use air fresheners, 20% more likely to develop cancer. Communication will give more to those who use stronger fresheners.
Expert opinion - the study was based on surveys. Cancer patients were asked how often they used fresheners, etc. But the problem is that our memories affects what we think true. In other words, sick people are firmly held in the memory of how they use these products because they believed their cause trouble, and healthy does not remember it. There is no sufficient evidence of the impact of cancer on the cleaners.
Version two - alcohol
Theory - Numerous studies have shown that even moderate drinking increases the risk of breast cancer . And the more we drink, the higher the risk.
Expert opinion - yes it is. Science has confirmed that alcohol causes cancer, especially breast cancer .
Third version - weight gain
The theory - the more the woman picking up extra kilos in adulthood, the higher her risk of breast cancer after menopause, as more tissue produces more estrogen.
Expert opinion - again, a wholly true. Maintaining a healthy body weight is one of the best methods of prevention breast cancer . Fat is not inactive, it produces hormones and other substances that influence the risk of developing cancer.
Version Four - deodorants
Theory - substances that block the sweat can cause breast cancer Because with sweat from the body does not produce toxins. And they, in turn, build up not far from the breast.
Expert opinion - this whole story began with the sending of e-mail anti-scientific nonsense. There are no facts proving the effect on the risk of anti-perspirant breast cancer does not exist.
Version fifth - Stress
Theory - Israeli scientists have discovered that experiencing considerable stress, young women are at increased risk due to the threat of breast cancer .
Expert opinion - although some scientists really believe that stress causes cancer, very little evidence of this. Most research has found no connection.
Version sixth - giving up breastfeeding
Theory - studies show that breastfeeding women less likely to get sick breast cancer .
Expert opinion - it's true. The longer a woman breastfeeds a child, the lower her risk of developing cancer.
Version seventh - chest injury
The theory - researchers from the University of Lancaster found that physical trauma can cause breast breast cancer .
Expert opinion - this view is not supported by any serious scientific evidence. But any doctor knows that cancer is primarily caused by the failure or damage to the genes, but not tissue. And its development takes a very long time. Most likely, because of injuries breast physicians simply are more likely to see the already formed tumor.
