Task: Answer Verification
Input (English): Question: Is persistent breast pain following breast cancer surgery associated with persistent sensory changes , pain interference , and functional impairments?
Answer: Subgroups of women with persistent postsurgical breast pain differed primarily with respect to the severity rather than the nature or underlying mechanisms of breast pain. Pervasive sensory loss and the association between persistent breast pain and sustained interference with function suggest the need for long-term clinical follow-up.
Output (English): yes
