Meet people with the same cancer in your area and share their experiences. Make them your friends. Use the app to find common ground or simply talk about your problems and everyday life.


The right support group may not always be available near you, or you may not be able to travel long distances. You can create your own group in the YES!APP or join an existing one. Find other people with the same disease and benefit from mutual support.


The YES!APP is supported by an interdisciplinary team of recognized cancer experts. Our experts have their own groups in which they answer questions, for example in the areas of blood cancer, gynecological oncology or palliative medicine.

We also organize weekly CALL-INs with our experts. The CALL-INs offer you first-hand information. In the livestreams, you can ask our experts your questions. It's easy to do so in the YES! app, via Facebook or by email.


Whether its in CALL-INs, groups, chats or with a YES!COACH – the YES!APP navigation menu means you’re only one click away from our main features. So you can easily find what you’re looking for.
