Chronic and acute pre-mastectomy pain as well as prevalence and characteristics of phantom phenomena following mastectomy were investigated by interview in a sample of 39 women who had undergone unilateral breast amputation. Twenty of 39 participants reported phantom sensations in the breast. Nine of the participants with phantom sensations experienced phantom pain and 11 non-painful phantom sensations. Although some features of phantom breast phenomena appear to be similar to characteristics of phantom phenomena in limb amputees, phantom breast phenomena seem to differ in a variety of ways such as time of onset or localization. This difference may be explained by the absence of kinesthesis and the small representation of the human breast. Seven of the 39 participants experienced chronic and six acute breast pain prior to the amputation. The amount of chronic pre-mastectomy breast pain weighted by the amount of involved tissue was significantly higher among participants with non-painful phantom sensations, compared to women with painful phantoms and those without phantom phenomena.
通过对39名接受单侧乳房切除的女性进行访谈，研究了乳房切除术前的慢性和急性疼痛以及乳房切除术后幻肢现象的发生率和特征。39名参与者中有20人报告了乳房的幻肢感觉。有幻肢感觉的参与者中有9人经历了幻肢痛，11人经历了无痛性幻肢感觉。尽管幻乳现象的一些特征似乎与肢体截肢者的幻肢现象特征相似，但幻乳现象在多种方面似乎有所不同，如发作时间或定位。这种差异可能是由于缺乏动觉以及人类乳房的表征较小所致。39名参与者中有7人在截肢前经历了慢性乳房疼痛，6人经历了急性乳房疼痛。与有疼痛性幻肢的女性和没有幻肢现象的女性相比，无痛性幻肢感觉的参与者中，按受累组织量加权的乳房切除术前慢性疼痛量明显更高。
