A new study found that some women with early stage breast cancer may be able to avoid chemotherapy. Dr. Larry Norton discussed these findings with PBS Newshour on June 4. According to Dr. Norton, a gene test called OncotypeDX can identify women who’s cancer is at risk for spreading. Patients with high scores benefit the most from chemotherapy, patients with low scores do not, but those in the middle are the ones that doctors have not been able to determine who should get chemo and who should not, until now.
