Certitidude is for breast cancer

Thank you for sharing what you've learned and for looking out for a friend. Blood tests that look for tumor DNA are a growing topic in cancer care, including for people with B-cell lymphoma, and whether a particular test makes sense depends on each person's diagnosis, so a lymphoma care team is the best source for those questions. Members of this community are welcome to share any experiences or questions about blood-based cancer tests so everyone can learn together.
