Obesity May Affect Breast Cancer Recovery

Women who are overweight or obese when identified as having some breast cancers have a greater risk of dying following a recurrence compared with women of normal weight, based on a U.S. study.

Obesity during the time of breast cancer diagnosis is assigned to poorer survival, but less is famous about specific subtypes from the disease, and treatments may be influenced by excess weight.

Once the U.S. National Cancer Institute sponsored treatment trials, researchers could explore if increasing excess fat affects breast cancer recurrence and survival.


It's becoming clear that women may not need to lose weight down to the normal range to gain health benefits.

"There's some evidence that for every one per cent of weight you lose, your insulin level, your estrogen level, your markers of inflammation will go down three per cent.


Goodwin's research suggested high levels of insulin accompanying obesity encourage tumour growth, and boost the likelihood of breast cancer recurrence.

The research included 6,885 women with Stage 1 to Stage 3 breast cancer who have been given chemotherapy with doxorubicin.

To sign up, the women had to have normal heart, kidney, liver and bone marrow function, meaning individuals with significant health issues were excluded.
