SABCS: IOM Lists Breast Cancer Risks in Environment
December 7, 2011
An expert report says that combination HRT, being overweight after menopause, and drinking alcohol are definitely linked to higher breast cancer risk. Read more...

This information is dated about 5-6 years old however see footnote #3.  I do agree life style choices does affect our health in many way - but not all the blame can be place on patients.  These experts need to look closer at the real environmental causes in our food, water and daily products used in our homes.  The incidence in breast cancer is rising and seen in younger women.  Don't forget we are the generation who used oral contraceptive pills.

1996        44,300        184,300          4.160

(1) Breast-cancer incidence rises from 68,000 to 184,300 between 1970 and 1996. Factor of Rise = 184,300 / 68,000 = 2.71. Rise = 171 %.

        (2) Female Population Rise from 1970 to 1995 = 134,461 / 104,309 = 1.29. Rise = 29 %. (Table 2)

        (3) There is no way that female population increase alone can account for the enormous rise in breast-cancer incidence.

        (4) During the same period (1970-1996), the number of breast-cancer deaths rose to 44,300 from 30,100. Factor of Rise = 1.47. Rise = 47%.

        (5) Meanwhile, the fraction of all U.S. women over age 60 keeps increasing (longer lifespan), which means more women are in the ages of high breast-cancer mortality. Thus the raw number of breast-cancer deaths per 100,000 women (all ages combined) has risen, while the AGE-ADJUSTED number of breast-cancer deaths per 100,000 females has remained almost constant.
