Tamoxifen is believed to stop the attachment, thus preventing or delaying breast cancer recurrence. Still, questions remain about the negative side effects of tamoxifen, Dr. Miller said. Its use might increase chances for blood clots, and some experts suggest that it might heighten the risk for ovarian cancer. Another therapy is evolving in the treatment of late-stage breast cancer. Antiangiogenic drugs used in clinical trials at the IU School of Medicine are designed to cut off the blood supply to malignant tumors.
Preliminary findings show some patients experience remission or a halt in their cancer's spread.
A number of factors place certain women at risk of contracting breast cancer, Dr. Miller said. African-American women, however, are more likely to die of breast cancer. The best defense against breast cancer is a solid offense - spearheaded chiefly by regular screenings. Dr. Champion strongly recommends that women over 40 obtain annual mammograms and clinical breast examinations. Women also should perform monthly breast self-exams.
