Is a circulating tumor test worth it for breast cancer?
Circulating tumor tests (also called tumor marker testing) are generally not recommended for routine monitoring after breast cancer treatment. These blood tests measure proteins that cancer cells may produce, but they're typically only ordered if you have symptoms suggesting the cancer has returned.
For most people who've completed treatment, standard follow-up care includes:
- Physical exams
- Mammograms (if you had breast-conserving surgery)
- Pelvic exams (if taking certain hormone therapies)
- Bone density tests (if taking aromatase inhibitors)
Your oncologist may use tumor marker testing to assess whether treatments are working if you're currently in active treatment, but it's not part of routine surveillance for recurrence.
The most reliable way to detect breast cancer recurrence is through regular physical exams, imaging tests like mammograms, and reporting any new symptoms to your doctor promptly. If you're concerned about recurrence risk, talk with your breast cancer specialist about which monitoring approach makes the most sense for your specific situation.
