Is the Signatures Circulating Tumor Test worth it?
The search results don't specifically mention the Signatures Circulating Tumor Test, so I can't provide detailed information about that particular test's value for breast cancer monitoring.
However, various tests play important roles in breast cancer care:
Genomic tests like Oncotype DX evaluate genes in cancer cells and provide predictions about:
- How the tumor is likely to grow
- How effective certain treatments will be
- The odds of the tumor returning later
Blood tests during treatment can help by:
- Measuring tumor markers that cancer cells produce
- Indicating whether treatments are working
- Monitoring overall health
Biomarker testing provides information about your cancer type, outlook, and likelihood of responding to specific treatments.
The value of any test depends on your individual situation, cancer stage, and treatment plan. It's worth discussing with your oncologist whether this specific circulating tumor test would provide useful information for your care decisions. They can explain how it might help monitor your response to treatment or detect changes early.
A MyBCTeam member shared about seeking additional testing: "My second-opinion facility recommended DNA testing for my tumor sample because I'm not responding to any of the treatments."
