Breast cancer is the second most common cancer among women in the world and in developed countries it is the most common. The early identification of women at risk is therefore of great importance and any additional measures which may aid diagnosis, particularly in high risk groups, would be of benefit. Breast volume and breast asymmetry were calculated from mammograms of 250 women with breast cancer and compared with those of 250 age-matched controls. There was evidence that breast cancer patients had more breast asymmetry and larger breasts than age-matched healthy women. The former observation is the first evidence that high breast asymmetry may be a risk factor for breast cancer. Breast asymmetry is likely to be a predictor of, rather than the effect of breast cancer.
乳腺癌是全球女性中第二常见的癌症，在发达国家则是最常见的。因此，早期识别有风险的女性非常重要，任何有助于诊断的额外措施，特别是在高危人群中，都将有益。从250名乳腺癌女性的乳房X光片中计算乳房体积和乳房不对称性，并与250名年龄匹配的对照组女性进行比较。有证据表明，乳腺癌患者比年龄匹配的健康女性有更多的乳房不对称和更大的乳房。前一项观察是高乳房不对称可能是乳腺癌风险因素的首个证据。乳房不对称可能是乳腺癌的一个预测指标，而非乳腺癌的结果。
