Overweight breast cancer risks

[Guest guest]

Hi All,

The pdf-available below paper found that being overweight was a risk factor for

getting and surviving breast cancer. Calories had nothing to do with it?

Association of Overweight with Breast Cancer Survival.

Am J Epidemiol. 2005 Dec 7; [Epub ahead of print]

PMID: 16339054

.... 1,455 breast cancer patients aged 25-64 years. ... median follow-up time for

this cohort was 5.1 years (1996-2002) after breast cancer diagnosis ... Being

overweight at cancer diagnosis or soon afterward ... was associated with poorer

overall survival and disease-free survival. Five-year survival rates were 86.5%,

83.8%, and 80.1% for subjects whose BMIs were <23.0, 23.0-24.9, and >/=25.0,

respectively (p = 0.02); the corresponding 5-year disease-free survival rates

were

81.9%, 78.1%, and 76.6% (p = 0.05). The inverse association between BMI and

survival

persisted after adjustment for age at diagnosis and other known prognostic

factors

for breast cancer, including disease stage. The authors found neither waist:hip

ratio nor waist circumference to be independently associated with overall

survival

or disease-free survival. ...

.... Additional adjustment for interval between disease diagnosis and interview,

usual physical activity, and total energy intake 5 years prior to diagnosis did

not

appreciably change the risk estimates ...
