    Radiotherapy for left-sided breast cancer poses a risk of cardiac irradiation, potentially leading to cardiovascular disease.

  • 2

    A study found no significant difference in cardiovascular hospitalization rates between left- and right-sided radiotherapy after 15 years.

  • 3

    Small increases in heart failure and ischemic heart disease were noted among women receiving left-sided radiotherapy, particularly in younger patients.

  • 4

    Contemporary photon radiotherapy has largely mitigated major cardiovascular risks historically associated with left-sided treatment.

  • 5

    Patient-specific risk assessment is crucial, as the incremental risk from radiotherapy varies based on baseline cardiovascular risk and treatment exposure.
