Complications are rare. But no procedure is completely free of risk. If you are planning to have this biopsy, your doctor will review a list of possible complications. These may include:
- Bleeding or bruising
- Nerve damage and chronic pain
- Allergy to dye
If the lymph nodes are removed, there is an increased risk of the following:
- Delayed wound healing
- Additional pain
- Lymphedema —a condition in which fluids collect under the skin causing swelling
Some factors that may increase the risk of complications include:
- Recent or long-term illness
- Poor nutrition
- Use of certain medications
- Bleeding disorders
