Monitoring
For post-surgical follow-up of patients with ductal carcinoma in situ (DCIS), the National Comprehensive Cancer Network (NCCN) recommends:[62]
History and physical examination every 6-12 months for 5 years, then yearly.
Annual diagnostic mammography (initial mammogram 6-12 months post-radiation for DCIS if breast conserved, then yearly).
For follow-up of patients with lobular carcinoma in situ (LCIS), the NCCN recommends:[47]
History and physical examination every 6-12 months beginning at diagnosis.
Annual mammography with digital breast tomosynthesis beginning at the age of diagnosis but not before age 30 years.
Consideration for annual breast magnetic resonance imaging (with and without contrast) beginning at the age of diagnosis of LCIS, but not before age 25 years.
Breast awareness (women should be encouraged to be familiar with their breasts and report changes to their healthcare provider).
High-quality evidence indicates that, in women with early breast cancer, follow‐up programmes based on regular physical examinations and yearly mammography alone are as effective as more intensive approaches.
