For Patients

In June 2022, the center was formed through the merger of the Breast Center Ostschweiz, the Tumor and Breast Center ZeTuP, and the Oncology Practice Vadiana, all of which have many years of experience in oncology, hematology, and senology (breast diseases). This merger created the largest private tumor center in Eastern Switzerland. Insured individuals of all health insurance providers receive patient-oriented diagnostics and therapies for all tumor diseases, in line with established guidelines. Excellent internal and external networking, organization and participation in interdisciplinary tumor boards, as well as involvement in clinical research groups, guarantee a high level of expertise across the entire spectrum of oncology and hematology.

Other key areas of focus of our medical team include tumors of the gastrointestinal and urogenital tracts, malignant diseases of the blood and lymphatic system, as well as genetic testing and counseling for familial cancer risk (also for relatives).

The process at ourTumor- und BrustZentrum Ostschweiz (Tumor and Breast Center Eastern Switzerland)

Registration at the Breast Center is usually done by your family doctor or gynecologist. If you have breast problems or questions, you are also welcome to make an appointment with us directly. We treat patients of all insurance classes.

We schedule appointments according to urgency. If you have suspicious breast changes, you will be offered an appointment for clarification within a maximum of 2 (working) days.

If you are unable to attend your appointment, please inform us as soon as possible.

We can quickly clarify changes in the breast or conspicuous findings. As part of the initial consultation, in addition to a detailed discussion, we carry out a palpation and ultrasound examination of the breast. In the case of conspicuous findings, a sample (biopsy) can be taken immediately with a thin needle. The procedure is performed under local anesthesia and takes around 15 minutes.

In most cases, a mammogram is also necessary for a comprehensive assessment during the breast consultation. These are carried out at the Klinik Stephanshorn. We schedule these directly before or after your appointment in our consultation. A shuttle service is organized by us and ensures a quick way to the mammography and back to us.

If necessary, we can organize additional examinations (e.g. MRI) for you through our radiology colleagues.

We will inform you of the result of the biopsy as soon as possible and discuss with you the further procedure in your individual situation. In many cases, the changes are harmless and do not require any further therapy.

However, if you are diagnosed with breast cancer, your findings will be discussed in our team and at our interdisciplinary tumor conference. At the Breast Center, we will then explain the therapy recommendation to you and advise you on this in detail. We then plan the further steps together with you.

If an operation is planned, we will discuss the procedure with you in detail. We attach great importance to ensuring that, whenever possible, you are operated on by the same doctor who carried out the examinations and therefore knows you and all the necessary findings best.

We carry out your operation at the Klinik Stephanshorn. In the case of breast cancer, we can offer you an operation date within 1–2 weeks at the latest.

You will receive all the necessary documents from the Klinik Stephanshorn. If you have any relevant pre-existing conditions, you may be invited separately for an anesthesia consultation. As a rule, however, you will be admitted to the clinic directly on the day of the operation.

You will be operated on by your attending physician from the Breast Center and subsequently cared for during your hospital stay. In the case of breast-conserving surgery, you can expect a hospital stay of 1 to 3 days.

Detailed information about your hospital stay can also be found directly via the Klinik Stephanshorn link:
www.hirslanden.ch/de/klinik-stephanshorn/ihr-aufenthalt/ablauf-ihres-aufenthalts.html

In the week after the operation, or at any time if needed, we will carry out a wound check in the Breast Center.

In the case of breast cancer, a second discussion will take place at the tumor conference after the operation. As part of the wound check, we will explain the findings of the tumor operation and their significance for the further course of treatment in a personal consultation. Additional treatments are often recommended for breast cancer to prevent a recurrence, such as radiation therapy to the breast or drug therapies.

For referring physicians

We strive to offer all medical colleagues and other referring parties the best possible service quality. We work in an accessible and problem-oriented manner and, depending on the task, either only carry out a consiliar clarification, or take over the complete further clarification and subsequent treatment, if this is desired.
We look forward to working with you!

Referral form for patients

With this online referral, you can refer your patient to us in just a few steps. You will receive a confirmation of the referral as an
email and an appointment confirmation as soon as the appointment has been arranged with the patient. Of course, you can also use our other contact options such as telephone or email. Thank you very much for your trust!
