Estrogen blood levels of women who had breast cancer recurrence were twice as high as those whose breast cancer had not returned, the researchers reported. Rock and team said that the next step is to find lifestyle modification factors that may benefit beast cancer survivors. Exercise has been ...
ESTROGEN LEVELS IN BREAST CANCER WOMEN IN PRE AND POSTMENOPAUSAL PERIODSSultan, Ali ShalashHamad, Entisar MahdiIbrahim AL-Mahdawi, Fatima KadhimBiochemical & Cellular Archives
The article highlights the results of a study which suggest that high levels of estrogen contribute to an increased risk of cancer recurrence, just as they lead to the initial development of breast cancer. The study's lead author, Cheryl L. Rock is a professor in the Department of Family a...
An Estrogen Model: The Relationship between Body Mass Index, Menopausal Status, Estrogen Replacement Therapy, and Breast Cancer Risk We present a mathematical model that lends support to the hypothesis that estrogen levels mediate the complex relationship between body mass index (BMI), m...

Excessive intake of high-protein, high-fat foods can cause elevated estrogen levels and increase the risk of breast cancer. The risk of breast cancer among obese people is 1 to 1.5 times higher than that of people with normal weight, and the risk of breast cancer spreading is 2 times highe...

Mutations inESR1, which encodes estrogen receptor-α (ERα), drive resistance to approved endocrine therapies in breast cancer. We studied the molecular response to the investigational ERα antagonist and degrader, giredestrant, in preclinical models and biopsy samples. We found that long-term inh...
However, epidemiologic studies assessing the link between exposure to pesticides or PCBs and breast cancer have generally not shown enhanced breast cancer risk with higher levels of xenoestrogen exposure. These findings heighten our uncertainty about the relevance of the preclinical findings to human ...
Women who carry the BRCA1 mutation tend to develop estrogen receptor (ER)–negative breast cancer,10 while women who carry the BRCA2 mutation tend to develop ER-positive breast cancer. However, the USPSTF was not able to find sufficient evidence on the benefits and harms of risk-reducing ...
Triple-Negative Breast Cancer Some breast cancers -- between 10% and 20% -- are known as “triple negative” because they don’t have estrogen and progesterone receptors and don’t overexpress the HER2 protein. Many breast cancers associated with the gene BRCA1 are triple negative. They are ...
