The stage at diagnosis and the survival experience of 41 women who developed breast cancer after cosmetic breast augmentation were compared with those of all other patients with breast cancer (n = 13,246) diagnosed in Alberta from 1973 to 1990 (inclusive). The tumors in women with breast implants were smaller (65.9 percent < or = 2 cm) as compared with the tumors in women without implants (34.1 percent < or = 2 cm), but lymph node and distant metastases were equally frequent in the two groups. The distribution of tumor histologic types did not differ significantly between women with or without implants. Women who had an implant were younger at diagnosis of breast cancer compared with women with breast cancer and no breast implants. The relative 5- and 10-year survival rates did not differ significantly between the two groups, and the Kaplan-Meier survival estimate also was similar. It is concluded that women with breast implants in whom breast cancer develops are not diagnosed in a later stage and do not experience an impaired survival as compared with breast cancer patients without implants.
将41例隆胸术后患乳腺癌的女性患者的诊断阶段和生存经历，与1973年至1990年（含）在艾伯塔省诊断出的所有其他乳腺癌患者（n = 13246）进行了比较。有乳房植入物的女性患者的肿瘤较小（65.9%≤2 cm），而没有植入物的女性患者的肿瘤较大（34.1%≤2 cm），但两组的淋巴结转移和远处转移发生率相同。有或没有植入物的女性患者的肿瘤组织学类型分布没有显著差异。与没有乳房植入物的乳腺癌女性相比，有植入物的女性在诊断出乳腺癌时更年轻。两组的相对5年和10年生存率没有显著差异，Kaplan-Meier生存估计也相似。结论是，与没有植入物的乳腺癌患者相比，患乳腺癌的有乳房植入物的女性并非在晚期被诊断出来，且生存情况也没有受损。
