For patients

The center emerged in June 2022 from the merger of the Breast Center Eastern Switzerland, the Tumor and Breast Center ZeTuP and the Oncology Practice Vadiana, all of which have many years of experience in oncology, haematology and senology (breast diseases). This merger has created the largest private tumor center in Eastern Switzerland. Insured persons from all health insurance companies receive patient-oriented and guideline-based diagnosis and treatment of all tumor diseases. Good internal and external networking, organization and participation in interdisciplinary tumor boards as well as participation in clinical research groups guarantee a high level of expertise in the entire spectrum of oncology and hematology.

The procedure at ourTumor and Breast Center Eastern Switzerland

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

We allocate appointments according to urgency. In the case of suspicious breast changes, you will be offered an appointment for clarification within a maximum of 2 (working) days.

If you are unable to keep your appointment, please inform us as early as possible.

We can quickly clarify any changes in the breast or abnormal findings. As part of the initial consultation, we carry out a detailed discussion and a palpation and ultrasound examination of the breast. If there are any abnormal findings, a sample can be taken immediately (biopsy) using 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 in the breast consultation. These are carried out at the Stephanshorn Clinic. We schedule these on the same day directly before or after your appointment in our consultation. A shuttle service is organized by us and guarantees a quick way to the mammography and back to us.

If required, we can organize additional examinations (e.g. MRI) for you via our colleagues in radiology.

We will inform you of the result of the biopsy as soon as possible and discuss the next steps in your individual situation with you. Very often, the changes are harmless and do not require any further treatment.

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

If an operation is planned, we will discuss the procedure with you in detail. It is very important to us that, wherever possible, you are operated on by the same doctor who carried out your investigations and therefore knows you and all the necessary findings best.

We will perform your operation at the Stephanshorn Clinic. In the case of breast cancer, we will offer you an operation date within 1-2 weeks at the latest.

The Stephanshorn Clinic will send you all the necessary documents. If you are known to have any relevant concomitant illnesses, 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 then cared for during your stay in hospital. In the case of breast-conserving surgery, you can expect to stay in hospital for 1 to 3 days.

You can also find detailed information about your hospital stay directly via the Stephanshorn Clinic link:
www.hirslanden.ch/de/klinik-stephanshorn/ihr-aufenthalt/ablauf-ihres-aufenthalts.html

In the week following the operation, or at any time if required, we carry out a wound check at the Breast Center.

In the case of breast cancer, a second discussion takes place at the tumor conference after the operation. As part of the wound check, we explain the findings of the tumor operation and their significance for the further course of the disease in a personal discussion. Additional treatments are often recommended for breast cancer in order to prevent a relapse, e.g. radiotherapy of the breast or drug therapies.

For referring physicians

We strive to offer all medical colleagues and other referring physicians the best possible quality of service. We work in a low-threshold and problem-oriented manner and, depending on the work order, we either only carry out a consultative assessment or, if desired, take over the complete further assessment and subsequent treatment.
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 confirmation of the referral by
e-mail and an appointment confirmation as soon as the appointment has been made with the patient. Of course, you can also use our other contact options such as telephone or e-mail. Thank you very much for your trust!
