About Us
SIS in a few words
The SIS was founded in 1976 in Strasbourg (France). Today, the SIS is a unique worldwide federation of more than a hundred learned or scientific societies, associations and groups, located in 5 continents, with a priority mission: to improve breast health by constantly putting the patient in the center of its concerns. It is a society turned towards the future with a particular focus on innovation, transdisciplinarity and contribution of digital technology.
Letter of the President, Professor Carole Mathelin

Dear Professors, colleagues, and friends of the International Society of Senology.
It is with pride and determination that I assume the presidency of our International Society of Senology at the start of 2026.
We have come a long way since its founding in 1976, and it is with emotion and joy that we will celebrate its 50th anniversary together on October 1 and 2.
Thank you to the previous Presidents for setting the SIS on the path to innovation; thank you for their initiatives, always focused on the well-being of our communities and our patients.
My mission will be to work with you to consolidate these five key initiatives:
1. CONFERENCES AND WEBINARS
• Support and promotion of the 23rd SIS World Congress in China (Tianjin, May 8–10, 2026). We hope it will be as successful as the 22nd Congress in Puerto Rico.
• Support and promotion of regional congresses across different continents, which offer tremendous opportunities for networking and sharing knowledge about the future of breast surgery, taking into account their specific geographic and societal contexts.
• Support and promotion of quarterly short-format webinars covering current developments in our discipline. These webinars are followed by thousands of breast specialists worldwide.
2. NEW MEMBERSHIP
• Encourage the recruitment of new members (individual or institutional), coordinated by our vice presidents to increase the SIS’s presence on all continents.
• Promote cooperation agreements in partnership with professional societies, hospitals, cancer centers, and educational institutions, to promote education (an international university degree in breast diseases is organized annually), research, and international publications, and to foster international collaboration.
3. CONTINUATION OF INTERNATIONAL ACCREDITATION PROGRAMS
• Continue to provide accreditation and certification for breast units seeking to enhance their expertise, strengthen their international visibility, and participate in the SIS/ISS network.
• Encourage the acceptance of young breast specialists into these units through fellowship programs.
4. PROMOTE OUR JOURNAL, THE EUROPEAN JOURNAL OF BREAST HEALTH, WHICH IS A POWERFUL TOOL FOR CONNECTING OUR VARIOUS MEMBERS.
5. ENCOURAGE AND SUPPORT INNOVATION IN BREAST HEALTH IN ALL ITS FORMS
Innovation prizes, awards, or medals will be awarded to teams proposing innovative solutions in the field of breast diseases.
All of this will be made possible thanks to you, the members of the board, members, and friends of the SIS, whom I look forward to seeing again on October 1 and 2, 2026, in Strasbourg to celebrate our 50th anniversary (at the European Parliament and at IRCAD, where the first innovation medals will be awarded).
Prof. Carole Mathelin, your President

- POURSUITE DES PROGRAMMES D’ACCREDITATION INTERNATIONALE
- Poursuivre les accréditations et certifications des unités de sénologie qui souhaitent majorer leur expertise, renforcer leur visibilité internationale et participer au réseau SIS/ISS.
- Favoriser l’accueil des jeunes sénologues dans ces unités dans le cadre des fellowships.

Des prix, récompenses ou médailles de l’innovation seront attribués aux équipes qui proposeront des solutions innovantes dans le domaine des maladies du sein.
Tout cela se fera grâce à vous, membres du bureau, adhérents et amis de la SIS que j’aurai le plaisir de revoir le 1ier et 2 octobre 2026 à Strasbourg pour fêter l’anniversaire de nos 50 ans (au Parlement Européen et à l’IRCAD où seront remises les premières médailles de l’innovation).
