Breast Cancer Care merged with Breast Cancer Now in April 2019. From October 2019 the new merged charity is called Breast Cancer Now.
However, lots of our patient information will continue to appear under the legacy brand Breast Cancer Care until new editions are produced. Please be assured that, whether the information you order or download is branded as Breast Cancer Care or Breast Cancer Now, the quality remains the same.
