  schema:description "Taking and holding a deep breath during each beam moves the heart away from the treated breast and roughly halves the dose it receives. England's national guideline has recommended it for left-sided breast cancer since 2018, yet surveys in Germany, Austria, Switzerland, Australia and the United States found it applied to a fraction of the people who could have it."@en ;
