Doctors have already begun reducing radiation treatment for women at low risk of recurrence or spread of the disease. A new study finds that some women at greater risk can safely avoid radiation.
Researchers followed 1,600 women for a median of 9.6 years and found that survival rates were similar in two groups of patients: 81.4 percent among the patients who had received radiation treatment and 81.9 percent among those who had not.
The transplanted portion of the genetically modified pig liver was removed after 38 days, and the patient, who had advanced liver cancer and cirrhosis, died several months later.
