Is SLNB used to help stage all types of cancer? ![]() A false-negative biopsy result gives the patient and the doctor a false sense of security about the extent of cancer in the patient’s body. A false-negative biopsy result-that is, cancer cells are not seen in the sentinel lymph node even though they have already spread to regional lymph nodes or other parts of the body.Skin or allergic reactions to the blue dye used in SNLB.Difficulty moving the affected body part.Numbness, tingling, swelling, bruising, or pain at the site of the surgery, and an increased risk of infection.Seroma, or a mass or lump caused by the buildup of lymph fluid at the site of the surgery.Very rarely, chronic lymphedema due to extensive lymph node removal may cause a cancer of the lymphatic vessels called lymphangiosarcoma. In addition, there is an increased risk of infection in the affected area or limb. In the case of extensive lymph node removal in an armpit or groin, the swelling may affect an entire arm or leg. There is less risk with the removal of only the sentinel lymph node. The risk of lymphedema increases with the number of lymph nodes removed. Lymphedema may cause pain or discomfort in the affected area, and the overlying skin may become thickened or hard. This disrupts the normal flow of lymph through the affected area, which may lead to an abnormal buildup of lymph fluid that can cause swelling. During lymph node surgery, lymph vessels leading to and from the sentinel node or group of nodes are cut. All surgery to remove lymph nodes, including SLNB, can have harmful side effects, although removal of fewer lymph nodes is usually associated with fewer side effects, particularly serious ones such as lymphedema.
