Case contribution: Dr Radhiana Hassan
Clinical:
- A 50 years lady
- She had wide local excision for right breast carcinoma about 2 years 3 months ago
- Surveillance mammogram after one year post operation was unremarkable
- Currently complaint of right breast lump
- No other symptoms
Mammogram findings:
- Both breasts are dense (BIRADS C)
- Stromal distortion in right breast in keeping with previous surgery
- No obvious mass lesion is seen
- No suspicious clustered microcalcification
Ultrasound findings:
- There are two hypoechoic avascular lesions in the right breast
- The lesions had irregular margins
- RtUOQ is 27 x 25 x 18mm and Rt7H measures 19 x 17 x 17mm.
Diagnosis: Recurrent breast cancer (HPE proven)
Discussion:
- Recurrent breast cancer refers to recurrence of malignancy within the same breast at or close to the resection bed more than two years following surgical excision.
- The rate of local recurrence may be as high as 19% in 10 years.
- The maximum recurrence occurs ~4-6 years post treatment.
- Having local recurrence doesn’t mean the cancer has spread.
- Recognized risk factors include: close or positive margins at time of resection, extensive intraductal components, inadequate adjuvant radiation therapy, multicentric or multifocal breast cancer and young age at presentation.
