Onco-sexology as a supportive care for patients treated for cancer is still rarely discussed or even non-existent in 2022. However, it's recommended to integrate the preservation of sexual health throughout the treatment and post-cancer process, given the impact of cancer, treatments and the importance of intimate life for a majority of patients.

Onco-sexology is one of the supportive care services validated by The French National Cancer Institute (INCa). It is also an objective of the 2014-2019 cancer plan and the 2017-2030 national sexual health strategy plan.

Although sexuality is one of the fundamental needs of the human being, including in the case of a chronic disease or cancer diagnosis, the lack of training of health professionals to deal with intimate life, the difficulty to exchange on this subject between caregivers and patients, the lack of financial support for onco-sexology consultations, are all obstacles to the global management of oncology patients. However, it's a request from patients to be able to discuss the subject in an intimate way with a professional.

While onco-sexology is already recommended as supportive care, a study on the impact of the delay in the management of sexual difficulties on quality of life could provide a sufficient level of evidence to change the practices and the care pathway of the oncology patient. Our objective is to study whether early management in onco-sexology has an impact on quality of life compared to late management (ie onco-sexology consultation before vs. after introduction of systemic oncological treatment).
