Urban myth:  coffee is bad for your breasts.

News:  coffee is good for your breasts.

Researchers in Sweden and the United Kingdom have been following 1090 breast cancer patients for several years now.  They have found that women who drink two cups of coffee a day have a significantly lower risk of breast cancer recurrence, especially if they are also taking tamoxifen (which means their tumors express estrogen or progesterone receptors.)  In fact, women with hormone positive tumors who were taking tamoxifen had a 50% reduction in their risk of breast cancer recurrence if they drank two cups of coffee a day.  Scientists also discovered that breast tumors were smaller in women who drank two cups of coffee a day.  And in laboratory studies coffee increased cancer cell death.

Not only is coffee not bad for you, if you have breast cancer it may help prevent recurrence of disease.  Two cups a day seems to be all that is needed.  I’d recommend you have a cup at breakfast and one at lunch because the caffeine in coffee can certainly interfere with sleep if consumed later in the day.

Have you tried cold-brewed coffee?  It’s delicious.  And it can be made in large batches that keep well in the refrigerator for up to five days.  Here’s my recipe:

Take 1 1/3 cups of regular ground coffee and put it into a large glass container with 6 cups of water.  Cover and let it stand overnight.  Strain the brew in the morning and place the coffee into a covered glass container.  Store in the refrigerator for up to five days.  Note:  I use a large French-press coffee maker, which works very well.
