Pectus exacavatum (PE) is the most common idiopathic chest wall deformity, affecting one in 300-1000 births.¹ Due to irregularities in chest wall shape, PE patients receiving radiation for breast cancer have increased risk of radiation dose to normal structures. Our report evaluates the suitability of different radiation techniques for a PE patient with right-sided breast cancer. Limited studies have examined radiation techniques in PE patients with breast cancer.^6,9,10 We were able to achieve most optimal coverage and dose distribution using volumetric modulated arc therapy.
