It is a centre for high quality patient care, research and teaching. It is highly-known for the treatment of (among others): skin cancers like melanoma, breast cancer, and lung cancer. It provides access to care with many expert doctors who have historically revolutionized the treatment of cancer and contributed to the surge of new molecules in the treatment of cancers and tumors. It is located in the Parisian area. It is named after Gustave Roussy, a Swiss-French neuropathologist. In April 2019, three new interventional radiology rooms were inaugurated, making it the largest platform of this type in Europe, entirely dedicated to oncology. Interventional radiology is a so-called "minimally invasive" diagnostic and treatment technique, which uses images to guide access to deep-lying organs, without having to "open up" patients. Gustave Roussy carries out more than 4,000 operations of this type each year. From Wikipedia
