How does Ostriker use metaphor in the poetry collection, Mastectomy?

Before and during the early part of the surgery, she sees herself in traditional feminine images. She imagines her breast as “succulent” and “juicy” like ripe fruit, suggesting that before the operation she felt womanly and fertile. As the surgeon removes her breast, the fruit metaphors shift to verbs associated with incision, chopping, and serving, as though the fruit associated with sexual attraction is now just a lump of matter to be handled with a knife and cleaned.
