Nine medical societies, including the American Society of Clinical Oncology and the American College of Cardiology, representing nearly 375,000 physicians are challenging the widely held perception that more health care is better, releasing lists Wednesday of tests and treatments their members should no longer automatically order.

The 45 tests and procedures considered to be overused include:

Repeat colonoscopies within 10 years of a first test
Early imaging for most back pain
Brain scans for patients who fainted but didn’t have seizures
Antibiotics for mild- to-moderate sinusitis unless symptoms last for seven or more days or worsen
Stress cardiac imaging or advanced non-invasive imaging in the initial evaluation of patients without cardiac symptoms unless high-risk markers are present
