Making sense of the ever-changing world of breast cancer can be quite overwhelming. The Understanding Breast Cancer section of our website is your one-stop resource for the latest information on breast cancer risk factors, early detection and screening, diagnosis and treatment. You will also find the latest on integrative and complementary therapies, follow-up care, support and much more.
The Understanding Breast Cancer Guide at the top left provides a complete list of all the topics found in Understanding Breast Cancer. Choosing a section (such as Treatment) below the Guide at the left will take you to a menu of the topics covered only in that section.
The Understanding Breast Cancer section was co-developed with Harvard Medical School faculty and Dana-Farber/Brigham and Women's Cancer Center staff.
Also, check out our Breast Cancer 101 (interactive tool). This tool uses animation and voiceover to help you learn all about breast cancer. It provides an audiovisual experience for those who prefer to get information by watching and listening rather than reading (although you can follow along with the text if you prefer).
Or, if you are newly diagnosed with breast cancer visit our interactive treatment navigation tool. This tool gives an overview of common breast cancer treatment plans in a non-overwhelming way. All you have to do is answer a few simple questions about your situation and then you will be presented with a series of basic treatment plans.
