Can uterine polyps turn cancerous 2 weeks after being biopsied and coming back benign? getting a d&c done next week. how fast can it turn to cancer?

Polyps : It is extremely unlikely for benign polyps to become cancerous so I would stop worrying

They very rarely do: At age 20, the risk that a cervical or endometrial polyp would be "cancer" is so remote as to be negligible. Many of the small polyps (under 1cm) require no treatment or removal particularly if they cause no symptoms ; they will often resolve spontaneously and disappear. Even in older perimenopausal or postmenopausal women, most of these polyps are usually benign. They do not "turn to cancer".
