At all and I doctor to Spencer is here with the. -- women should really pay attention to it's not the first a look at the question but it's the biggest in the best. A 100000 women they were all nurses they were followed for 28 years. To look at the relationship between alcohol and and breast cancer age thirty to 55. In what they found was was a little surprising as little as as. Three -- six drinks per week. Increased a woman's risk of breast cancer by 15%. And the more you drank the greater the increase in risk and that's important. As it. But doesn't matter what type of alcoholics alcoholics and it didn't matter -- we talk about red wine and other one time he didn't matter where there was a class a red wine beer -- shot of alcohol was all the same what is the link between alcohol and breast cancer. Well you know it's alcohol can increase the amount of estrogen that circulates in your body and we know that especially as women get older -- -- Estrogen is a risk factor for breast cancer so women who have a relative who may have died or relatives who died of breast cancer and have that risk. There's not a lot you can do to reduce that risk but here's something you could do and that's doctoring. You bring -- red wine. And more women die from heart disease than they do from breast cancer and we've been told out of an occasional glass of red -- Doesn't hurt them in fact it may help that's right so people here study like this rich you know they're just there had a swimming you know -- information. And this is what makes -- so confusing you know there's so many states there's lots of studies that -- that having a drink a day or a little less. Decreases your risk of heart disease and dying of heart disease one in three women will die from heart disease one out of 36 will die from breast cancer.

That heart disease risk really takes a team you know -- takes a front -- You don't want anyone wanna give up that drink you wanna start drinking because of -- Hadassah medical yeah bacteria but if they are having an occasional drink it don't stop because of that and that this that it a look at. Cancer returning the recurrence you didn't this is just looking at first cancer so women who have breast cancer. This doesn't say anything about that I think all in moderation don't we don't overreact -- study. You -- stressing that isn't good -- either all right thanks a lot courage appreciated.
