A phase Ib clinical trial of the tablet form of olaparib, a PARP inhibitor, in combination with paclitaxel and carboplatin chemotherapy in heavily pretreated patients with advanced-stage ovarian cancer finds the drug to be safe and effective, especially in those women with BRCA gene mutations. The...
Findings from the National Lung Screening Trial (NLST) showed that screening high-risk individuals (smoking history of ≥ 30 pack-years) aged 55 to 74 with low-dose computed tomography (CT) vs chest radiography reduced lung cancer mortality. Following the study results, the U.S. Preventive...
Despite conjecture in the lay media that wearing a bra may be a risk factor for breast cancer based on the potential for bras to interfere with lymph circulation and drainage, hampering the removal of waste and toxins, there were few scientific studies investigating the issue. Now, a new study by...
Results from a large population-based study of 189,734 women diagnosed with early-stage breast cancer in California show the percentage opting for a bilateral mastectomy has increased substantially over the past decade even though the procedure was not associated with a lower risk of death than...
