How does Ostriker use imagery in the poem, Mastectomy?

In the third stanza, the speaker uses a series of images to describe her body as the doctor performs the operation. She asks the doctor whether her flesh was “succulent” and “juicy” like the fruit she later names. The image of flesh as grass is rather obscure here. Grass is a living thing like flesh unless it becomes detached, and it also serves as a groundcover. One could compare that to how flesh covers the body’s organs. Anesthetized, the speaker dreams about her flesh not as grass but as ripe fruit while the doctor makes his incisions. First, she imagines her flesh as candied fruit that the doctor “displays,” then as green honeydew and then “like a pomegranate full of seeds.”
