This again depends upon number of factors.
Site of the cancer.
Previous attempts at biopsy.
Fitness for anesthesia and open biopsy.
Patient's own choice.
I would certainly prefer needle biopsy due to minimal invasion and least possible chances of complications.
However, which procedure suits best a particular patient depends upon the particular clinical scenario and the decision has to be made in close liaison between the physician, pathologist/surgeon (who will perform the biopsy) and the patient.
