the study tested 40 women who have had a mastectomy. They were tested for 5 different parabens, of which 99% were found to have them. Different types of parabens were found in different parts of the breast tissue tested ((n-propylparaben, methylparaben, n-butylparaben, ethylparaben and isobutylparaben).
The study did not compare breast tissue from healthy womenand the study did not prove that there is any connection with parabens and breast cancer. Nor have any studies be done to confirm that parabens will also be found in male breast tissue.
There was no study done to connect skin care or deodorants with parabens found in breast tissue, although it has to be mentioned that some 7 % of the women participating in the study had never used deodorants. That in itself does not mean much as most deodorants do not contain parabens as they do not need to be used as a preservative in these products
indeed parabens are also found in foods, and even in naturally occurring foods, so there has to be a lot more testing to see if we can absorb parabens from foods or absorption from skin care
Studies have shown that parabens have similar properties to oestrogens, and researchers do know that it does play a role in the development of breast cancer but it is still speculation at this stage over how/why and we have seen enough studies that show potatoes give cancer as they also have " a role in the development" so I am waiting to see a lot more evidence. For a start we know that food has a role in cancer/diabetes and we still all eat lol (attemp at humour as this is getting very heavy)
well you said go ahead, have kept this brief, but there is a lot of stuff about this on google, have a look but be aware of who posts what and what role they have in natural skin care vs use of preservatives in skin care. Natural does not always mean best and people can have reactions to anything, even natural ingredient
The study which caused all the controversy as the Daily Mail reported it very oddly:
