[Radiosurgical labeling of non-palpable mammary lesions].

BACKGROUND

The frequency of breast cancer is increasing worldwide and mammography allows the diagnosis of concealed lesions.

AIM: To assess the diagnostic yield for carcinoma of non palpable lesions detected by mammography.

PATIENTS AND

METHODS

We studied 46 patients, aged 24 to 67 years old, in whom a radiosurgical labeling of non palpable mammary lesions was performed. In all patients, a surgical biopsy was obtained, but the pathological study was available in only 40 patients.

RESULTS

The mammographic appearance of lesions were microcalcifications in 40% of women, stellate images in 27.5%, asymmetry in density in 5% and the association of microcalcifications and other signs in 20%. Seventy seven percent of lesions were benign. Four patients had an in situ ductal carcinoma, two had a predominantly in situ carcinoma and 4 had an invasive ductal carcinoma.

CONCLUSIONS

Our results are similar to those reported abroad. The finding of 5 minimal carcinomas underscores the effectiveness of mammography as a screening method for breast cancer.
