Re: breast cancer
Exactly, you said it youself. Naiki Ka Zamana nahi hai.
As for Vanity Fair, they do not sell bras, they are a fashion magazine. Jidher itni googling ki hai you should have googled this and then said anything about Vanity Fair. As far La Senza or any other bra manufacturer and seller goes, I am not there sales representative or something. 
Exactly even though there is data collection, it is not concrete and as far as studies go, you presented one study I presented two studies opposing your STUDY.
Good that you rest your case. 
In science and maths there is nothing absolute. Especially in science, there will be one study and then someone else will come and challenge that study. The human body is a very complex thing to understand and this is why many studies are done. NOT just one and decisions cannot be based on the basis of just ONE study saying for instance that BRAS should not be worn. People will be in the wrong if they do do that.
