The initial Method of Detection (MOD) is the first test or sign or symptom that triggered the subsequent workup and recommendation for biopsy.
Method of Detection
Why MOD?
- USA National cancer registries do not include data about how breast cancer was detected.
- We cannot answer basic questions about how screening impacts outcomes in the USA.
- The debate over when to start and how often to screen rages on in the USA.
- Many other nations track screening mammography at the patient level.
