The THYROID CANCER ALLIANCE (TCA) is an international network of national thyroid cancer support organisations and/or thyroid support groups, dedicated to working together by providing support, information and encouragement to those affected by the disease throughout the world. It does this through:

  • Developing programmes and projects that promote education and awareness of thyroid cancer to the general public and medical professionals;
  • Bringing together leaders of national thyroid and/or thyroid cancer support groups so that they can share information and learn from each others’ experiences; and
  • Promoting thyroid cancer awareness all over the world.

The TCA became an Association with full legal capacity in the Netherlands in 2017, Kamer van Koophandel (Chamber of Commerce) number 69100748.

In all cases, we DO NOT pass on your contact details to any third party unless you give us permission to do so, and any contractors employed at any time who may, for reasons beyond our control, have access to information are required to sign a confidentiality agreement.
