The role of mammography in detecting breast cancer in augmented breasts.

Recent reports suggest that mammographic findings may be compromised in patients who have undergone augmentation mammoplasty. Therefore, early detection of breast cancer by mammography may be obscured. We reviewed records for our patients with breast cancer after augmentation mammoplasty to define further the role and accuracy of mammography. Six patients aged 34 to 52 years (mean, 42 years) had a diagnosis of breast carcinoma 4 to 14 years (mean, 7.2 years) after augmentation mammoplasty. Five patients had preoperative mammographic examinations. Suspicious lesions were seen in 4 patients, and microcalcifications were identified in the fifth. The sixth patient had a normal xeromammogram. Pathological diagnosis was infiltrating ductal carcinoma in 5 patients and intraductal carcinoma in 1. Findings for lymph nodes were negative in 3 patients; 2 others had positive findings in one lymph node, and 1 had positive results in four lymph nodes. Five patients had a suspicious mass that was palpated on self-examination or by the patient's plastic surgeon, and the sixth patient had a routine screening mammogram. Two of 3 patients with positive lymph nodes received adjuvant chemotherapy. This report confirms the role of mammography as a screening tool in making the diagnosis of breast cancer in women who have undergone augmentation mammoplasty. The importance of self-examination and follow-up by the plastic surgeon is stressed. The data suggest that mammography remains an accurate method for detecting breast lesions.
