A new case of radiation-induced breast angiosarcoma

Highlights • A biopsy of any suspicious breast skin lesion after radiotherapy is recommended. • Patients with clinical anomalies post-breast cancer surgery and RT need attention. • The Angiosarcoma was cured due to surgery and high-dose neoadjuvant chemotherapy. • A correct 6 month follow-up is needed: check-ups, chest X-rays and ultrasound. • The survival of the patient suggests possible ways to manage this rare tumour type.
