Your concerns about having another biopsy are understandable given the infection on the previous one.
However, as they have found a nodule, would a template biopsy be offered to you, which has a reduced risk of infection, going through the perineum.
I recently had this procedure without any problems, targeting the lesion, leading to positive diagnosis and treatment.
Ultimately your choice, but I know what mine would be.
Good luck which ever path you take. G
