Breast cancer screening: using familiality for earlier detection

It is the purpose of this study to investigate whether breast cancer in patients with a positive family history is detected at an earlier stage with better prognostic markers than breast cancer in patients without a positive family history. In 481 patients, tumour size, tumour type, lymph vessel invasion, blood vessel invasion, receptor state, lymphatic spread, mitotic activity index (MAI) and survival were measured and compared, according to their family history. No difference was found between patients without a family history, patients with first-degree relatives or patients with second-degree relatives with breast cancer. Tumours were detected in the same stages and prognostic factors, MAI and survival were similar in all groups. A positive family history of breast cancer does not lead to earlier detection of breast cancer or a better survival.
