About us

Our Vision - Experience the future with us!


It is now generally recognized that every physical condition can go through 6 phases. To give you an example: a simple cough in phase 1 can develop into a very serious lung disease in phase 6 – via another 4 intermediate stages.

Thermography is in phase 2, so it detects at the beginning of a possible problem. This means that it is generally still possible to reverse this process. Thermography is therefore above all a preventative method. And medical care should, in our opinion, be a lot more about this anyway!


If you get a ‘sneak preview’ in your health, using thermography, you can also stay at the steering wheel yourself and do whatever it takes to restore the balance in your body. In the thermography report that you receive after the treatment, you get the necessary preventive health advice.

A network of experienced therapists

Of course it happens sometimes that we notice a thermography that seems to have developed further than phase 2. In that case we would like to refer you to one of the excellent doctors and therapists in our network, who are all well acquainted with medical thermography.

You will continue to control your own health. But the whole team of De Groene Zuster would like to think along with you!

At present, one in seven women in the Netherlands is diagnosed with breast cancer – an alarmingly high number, Francine van Broekhoven also found. That is why she studied the phenomenon of breast health, with the idea that women should be better informed. In addition, it is important that women have access to a preventative research method such as thermography.

What Francine has touched most on her quest is the ignorance of many women about the way breast problems can arise, and what they can do to prevent this.

This made her decide to give women good information about breast health, and to start preventive breast health studies using thermography. Francine’s mission is now: Promoting breast health.

In addition to the breast examinations, Francine and her assistants also offer full-body studies, for both women and men.

Francine lives in the Netherlands and travels along with her colleagues to almost twenty locations in the Netherlands and Belgium to carry out the thermographies. She is also a trainer in Medical Thermography and teaches breast health to women who are interested in breast health workshops.

In May 2016 her first book was published: the Handboek Borstgezondheid (publisher Akasha). A telling quote from this is:

“It is time for women to wake up and start to wonder what they can do to keep their breasts healthy. They must be supported with a research method that is safe and radiation-free and is also suitable for women from the age of 23. “


  • 90% of breast diseases are caused by lifestyle.
  • You can make healthy choices with the right information.
  • This way you can lead a relaxed life and look at your breasts without fear.

Visit one of our lectures for:

  • answer to the questions that almost no one spontaneously asks about breasts;
  • tips for prevention and self-examination;
  • information about risk factors;
  • a critical view of the existing research methods;
