The treadmill exercise test with electrocardiogram (ECG), also known as an exercise stress test, is one of the most familiar tests in medicine.

In a randomized trial, published in The Lancet Oncology, Mayo Clinic Comprehensive Cancer Center researchers uncover evidence supporting a shorter treatment time for breast cancer patients. The study compared two separate dosing schedules of pencil-beam scanning proton therapy, the most advanced type of proton therapy known for its precision in targeting cancer cells while preserving healthy tissue to reduce the risk of side effects.
