Learning objectives
Tounderstandrecurrent breast cancer epidemiologyand risk factors.
To understand various surgical treatment methods of breast cancer.
Tounderstandvarious imaging findings of post-operative benign findingsafter breast cancer surgery.
To understand imaging findings of breast cancer recurrence.
To understand differential diagnostic point of recurrences compared with benign post-operative change.
Background
Breast cancer has relatively good prognosis,
however recurrent breast cancer is the leading cause of death.Close clinical and imaging follow-up is important in breast cancer patients for early detection of recurrence.However,
altered breast with various postoperative change makes radiologist confused to recognize recurred cancer.
We will review multimodality imaging with mammography,
ultrasound,
MRI and PET-CT of post-operative breast and figure out the differential diagnostic point of recurrences compared with benign postoperative changes.
Findings and procedure details
1.
Breast cancer recurrence statistics and risk factors
Both radical surgery (mastectomy) and breast conserving surgery are used in breast cancer treatment.
Local recurrence can occur after both radical and breast conserving treatment.
Recurrence occurs in approximately 5% of patients at 5 years with a local failure rate of approximately 1%-2.5% per year. After 5 years,
the risk of recurrence then diminishes,
but patients remain at risk even 10 years after treatment.

Conclusion
Understand epidemiology of breast cancer and surgical options,
conduct proper evaluation of postoperative changes after surgical management of breast cancer,
and distinguish benign finding with local recurrence are important for radiologist tohelp managing patients.
