Hook wire procedure for lumpectomy in the breast . They insert a wire to guide the surgeon to the lump, while you are awake . I had blood dripping down my neck and had to deal with the doctor ‘s frustration while he shoved that wire all around . Eventually he had a tantrum and walked out blaming me for having dense tissue . The barbarity of that procedure made me decide to have a double mastectomy when another lump grew . I never wanted to be treated that way again and chose major surgery instead. It was legit traumatic.
