Breast cancer cells recycle to escape deathA number of breast cancer cells facing potentially lethal antiestrogen treatment recycle to survive, scientists say.
About 70 percent of breast cancer cells have receptors for the hormone estrogen, which acts as a nutrient and stimulates their growth. Patients typically get an antiestrogen such as tamoxifen for five years to try to starve them to death, says Dr. Patricia V.
