For patients with the most common type of noninvasive breast cancer, routine testing for estrogen and progesterone receptors in tissue taken at the first needle biopsy is both unnecessary and wasteful, according to results of a study led by Johns Hopkins pathologists. The results for people with...
Many breast tumors grow in response to female hormones, especially estrogen. Drugs that reduce estrogen levels in the body often are effective in reducing tumor size and preventing recurrence of the cancer. But some tumors become resistant to these therapies and continue to grow and spread. A new...
