加专家认为：妇女乳房自我检查乳房无益有害
路透社纽约健康消息 加拿大预防医学专家小组指出，一直对40至69岁妇女推荐的乳房自我检查无益有害。该结论发表在近期《加拿大医学会杂志》上。
多伦多大学的南希·巴克斯特博士及其同事回顾了从1966年至2000年10月发表的关于乳房自我检查与乳腺癌死亡率关系的八个研究报告，比较常规进行乳房自我检查或接受了乳房自我检查教育与没有进行乳房自我检查或接受乳房自我检查教育的妇女。他们发现，没有证据表明前者比后者的乳腺癌的死亡率少；有证据显示进行乳房自我检查有害。因为比较在一些研究中进行的活组织检查结果，发现在前者中发现更多的良性肿瘤病例。(活组织检查是取小部份组织作样本以检查疾病证据的一种检验方法。)
专家小组建议不要继续推荐年龄在40至69岁的妇女进行乳房自我检查。对于年龄大于70岁的妇女，也没有足够证据显示应该向她们推存这种自我检查方法。对于年龄小于40岁的妇女，专家小组认为很少有证据说明乳房自我检查是有效的，因为在这个年龄段，乳腺癌的发病率较低，进行乳房自我检查及进行乳房自我检查教育可能无益有害。

巴克斯特认为，妇女可以自己发现乳腺肿块或乳腺癌，但大部份人都不是在作乳房自我检查时发现的。当进行洗澡、穿衣或做爱时，妇女应留意自己的乳房，如果她们发现任何异常情况，应去看医生，这是非常重要的。
然而，并不是所有专家都认同这种说法，因为这个做法长期以来已被广泛推荐给妇女。美国癌症学会发言人乔安娜·谢兰巴曲指出，进行乳房自我检查是有价值的；经常进行乳房自我检查的妇女，对乳房发生的变化很敏感，更易发现体积尚小的肿瘤。
哈佛大学医学院的苏珊娜·W·弗莱彻博士及其同事在为《加拿大医学会杂志》所写的社论里同意加拿大专家小组的意见，即目前仍无证据显示乳房自我检查对于发现乳腺癌有帮助，更多的证据表明它可造成损害。通过乳房X线检查及详细的临床乳房检查，临床医生有足够的手段以发现乳腺癌。应该强调的是对高危人群进行乳腺癌筛查。

Breast Self-Exams Don‘t Help Older Women: Study
NEW YORK (Reuters Health) - Women between the ages of 40 and 69 should not be taught to perform breast self-examination, says the Canadian Task Force on Preventive Health Care.
``From reviewing the literature there is no evidence of any reduction in breast cancer mortality from regularly performed breast self-examinations or breast self-examination education,‘‘ Dr. Nancy Baxter, from the University of Toronto, told Reuters Health.However, not all experts agree that the practice, which has been widely recommended to women for years, is without merit.

``We feel there is value is doing a breast self examination and continue to feel that way,‘‘ said Joann Schellenbach, a spokesperson for the American Cancer Society (news - web sites). ``Women who examine their breasts regularly become very sensitive to changes in the breast tissue and are more likely to find cancers when they are smaller.‘‘
In a new analysis, Baxter and colleagues looked at eight studies published between 1966 and October 2000 that looked at the effectiveness of breast self-examination in reducing mortality from breast cancer.

According to Baxter, the data did not show any benefit from regular breast self-examinations or breast self-examination education compared with no breast self-examination.
The analysis also revealed evidence that breast self-examination instruction could in fact be harmful, the research team reports in the June 26th issue of the Canadian Medical Association Journal. For example, some studies found higher rates of benign biopsy results among women assigned to learn self-examination than among women who didn‘t learn the technique. A biopsy is a test in which a small sample of tissue is removed and examined for evidence of disease.

The task force recommends that women 40 to 69 years of age not be taught breast self-examination. For women older than 70 years of age, the task force says, there is not enough evidence to make a recommendation as to the benefit of breast self-examination.
For women younger than 40, the task force says there is little evidence of the effectiveness of breast self-examination, adding that ``because the incidence of breast cancer is low in this age group, the risk of net harm from breast self-examination and breast self-examination instruction is even more likely.‘‘

``Women do find breast lumps and they do find breast cancers themselves. Most are not found during breast self-examination,‘‘ Baxter said. ``Women should remain aware of their breasts when they are showering, when they are dressing and during sexual relations, and if they do find anything it is very important that they contact their physician.‘‘
``We agree with the task force that there is still not much evidence breast self-examination helps and that there is more evidence it can harm,‘‘ Drs. Suzanne W. Fletcher, from Harvard Medical School (news - web sites) in Boston, and a colleague write in a journal editorial.
``Clinicians have much stronger evidence for mammography and well-done clinical breast examination, and we should emphasize these screening methods with our patients,‘‘ the editorialists advise.
