Desmoid Tumors: The Basics

Desmoid tumors are rare and locally-aggressive growths. They are not commonly known or understood, and being diagnosed with one can leave you with more questions than answers.1-3 Doctors have described desmoid tumors as having “tendril-like” growths because of how they look and how they can invade surrounding parts of your body. These “tendrils” can grow unpredictably.2

You don’t have to feel like your desmoid tumor is taking over your life. Understanding this condition is the best way to have a voice in your care. It’s also important to know what to ask your doctors and care team—so you can have a better understanding of the condition and its impact on your life. Learn more about desmoid tumors>
