Prof. Veronesi obtained his medical degree from the University of Milan in 1952, and soon decided to dedicate his professional activity to the study and treatment of cancer; after brief periods in U.K. and France, he joined the Italian Cancer Institute in Milan of which he became Director in 1975.

Veronesi is known as the founder of breast-conserving surgery in breast cancer treatment with the proposal of radiosurgical technique which challenged the idea, then dominating, that cancers could be treated only with aggressive surgery; since then, he has supported and promoted scientific research aimed to improve conservative techniques and patients quality of life.
Following this path, he developed sentinel lymph node biopsy with 99Tc and made possible to avoid axillary dissection in breast cancer with clinically negative lymph nodes.

He then developed a technique of intraoperative radiotherapy with electrons (ELIOT) to the area at risk of local relapse. He also contributed to breast cancer prevention, conducting studies on tamoxifen and retinoids verifying their capabilities to prevent the formation of carcinoma.
Prof. Veronesi was Health Minister of the Italian Republic and member of the Italian Senate. He published more than 800 scientific publications and 12 oncological treatises; he was awarded with fourteen Honorary Degrees throughout the world.
Currently, Prof. Veronesi is Scientific Director Emeritus of the European Institute of Oncology in Milan.
