Does Use of opiates affect the out come of a breast biopsy?

Answer 1

No, what makes you think it would? An opiate will not change a tumor from cancerous to non-cancerous or from non-cancerous into cancerous. The tumor will be what it is. If an opiate would make a cancerous tumor non-cancerous, you would see it being injected into every malignant breast tumor in the U.S. in order to end the disease.

If this is not what you were asking, please clarify, as your question can be open to interpretation.
