This procedure will help the doctor make an accurate diagnosis and recommend treatment if necessary. There are some risks when you have general anesthesia. Discuss these risks with your doctor. A local anesthesia may not numb the area quite enough and you may feel some minor discomfort. Also, in rare cases, you may have an allergic reaction to the drug used in this type of anesthesia.
Local anesthesia is considered safer than general anesthesia.
A lumpy scar called a keloid could form in the area of the incision. There may be infection and bleeding at the site of the incision. You should ask your doctor how these risks apply to you. A disadvantage of this biopsy is that the entire lump has not been removed. It will usually require additional treatment or surgery.
