These tests, involving anatomy and cytopathology, molecular biology or imaging (radiology and nuclear medicine) are prescribed by the oncologist, whether a surgeon, medical oncologist or radiotherapist. The Centre Léon Bérard offers all these tests on one single site. While many advances have been made over the past five years in the field of cancer treatment, the same is true for tumor diagnosis and care, thanks to increasingly precise equipment that requires fewer contrast products, and access to advances in genomics, with tumor DNA sequencing, in clinical trials such as the PROFILER trial, designed and coordinated by the Centre Léon Bérard.
