After Menopause, Women May Lower Risk with Strenuous Exercise
Vigorous exercise may lower the risk of breast cancer in post-menopausal women.
-
Lab Study Looks at Why Cancers Become Resistant to Tamoxifen
Basic laboratory research has found that certain invasive lobular breast cancers may not respond to tamoxifen because they develop a protein receptor that stops tamoxifen from working.
-
Hormonal Therapy Side Effects Linked to Lower Risk of Recurrence
New research suggests a link between hormonal therapy side effects (hot flashes, night sweats, joint pain) and a reduced risk of breast cancer coming back.
-
3-D Ultrasound Can Help Determine if Suspicious Areas are Cancer
A small, early study suggests that speed-weighted 3-D power Doppler can help doctors decide if a breast mass is cancer or not.
-
Lab Study Suggests Second-Hand Smoke Ups Risk
Exposure to nicotine from cigarettes you smoke as well from second-hand smoke from other people's cigarettes seems to make breast cancer cells grow and spread.
-
Changes in Heart Rate May Cause Sleeping Problems During Treatment
Changes in heart rate patterns and cortisol levels seem to be linked to sleeping problems in women being treated for advanced (metastatic) breast cancer.
-
No Link Between Coffee and Risk
A new study provides more evidence that there seems to be no link between caffeine and breast cancer risk.
-
Doctors Not Recommending Mammograms for Medicaid Patients
A new study shows that women in the North Carolina Medicaid program aren't getting regular mammograms because the screening isn't recommended by their doctors.
-
Zoladex May Help Reduce Risk of Recurrence
After surgery and other treatments for hormone-receptor-positive early-stage breast cancer in premenopausal women, treatment with the hormonal therapy medicine Zoladex (chemical name: goserelin) can lower the risk of the cancer coming back and improve overall prognosis.
-
Protective Tamoxifen May Lead to Earlier Diagnosis of Hormone-Receptor-Negative Cancer
Women at high risk who took tamoxifen and developed hormone-receptor-NEGATIVE breast cancer had the cancer diagnosed earlier compared to women who didn't take tamoxifen. (Tamoxifen doesn't reduce the risk of hormone-receptor-negative breast cancer.)
