Clinical Trials

Breast cancer clinical trials evaluate the effectiveness and safety of medications or treatments by monitoring their effects on large groups of people.

Mayo's clinical trials include experimental treatments, often unavailable elsewhere, which frequently lead to improved patient care for people worldwide.

A clinical trial of a new targeted breast cancer drug, led by physicians at Massachusetts General Hospital (MGH) Cancer Center, has begun enrolling patients.

An international trial has shown that switching from tamoxifen to exemestane afer 2 to 3 years increases disease-free survival and shows a slightly reduced risk of death for women treated for early stage hormone-sensitive breast cancer.
