Conversely, 25% of clinically benign-appearing lesions will be malignant when biopsied (21). Biopsy Techniques It is preferable for the patient to be involved in planning her therapy. In most instances, initial biopsy can be followed by definitive treatment at a later date. This approach allows the physician to discuss alternative forms of surgical therapy with the patient who has a malignancy. It gives the patient an opportunity to obtain a second opinion before undergoing definitive treatment. The technique has a high level of diagnostic accuracy, with low false-negative rates and rare, but persistent, false positive results (20,22). In most reported series, false-negative rates range from 10% to 15%, and false-positive rates are generally less than 1%, whereas insufficient specimens account for about 15% of samples (23). In younger women, it is prudent to moni to r a benign-appearing mass for one or two menstrual cycles. For benign cysts, cy to logic examination is not necessary if the fluid is nonbloody and the cyst resolves after aspiration. Core biopsy of nonpalpable breast lesions usually is performed using mammographic or ultrasonographic guidance. Under imaging guidance, a biopsy needle is inserted in to the lesion and a core of tissue is removed for his to logic examination. Devices with suction assistance often are used to increase the volume of tissue removed for evaluation. A titanium clip often is used to mark the biopsy site and serve as a guide should further excision be required. If a definitive diagnosis is not established, these procedures must be followed by open biopsy. Excision must be performed if the results with needle biopsy are equivocal or discordant with the clinical findings. An unequivocal his to logic diagnosis of cancer should be obtained before treatment of breast cancer is undertaken. Cy to logic diagnosis may be relied on if the mass clinically or mammographically appears to be malignant. Open biopsy can be performed in the outpatient setting with local anesthesia in the following manner (although this technique largely is replaced by core biopsy and usually is not necessary): the patient is positioned and the location of the mass confirmed. Local anesthesia is used to infiltrate the skin and subcutaneous tissue surrounding the palpable mass. It should be situated in such a way that it can be excised with an ellipse of skin should the patient require a subsequent mastec to my, or placed cosmetically so that partial mastec to my can be performed successfully through it. Para-areolar incisions are appropriate only for lesions in proximity to the nipple–areolar complex. The mass is gently grasped with Allis forceps or with a stay suture and moved in to the operative field. Larger lesions that are difficult to to tally excise can be incised for diagnostic purposes only. When an incisional biopsy is performed, a frozen section should be obtained to confirm that appropriate tissue for diagnosis is present. A cosmetically superior result will be achieved if the deep breast parenchyma is not reapproximated. The most superficial subcutaneous fat can be reapproximated with fine absorbable sutures, and the skin can be closed with a subcuticular suture and adhesive strips. Image-Guided Localization Biopsy Biopsy of nonpalpable lesions is a potentially difficult procedure that requires close cooperation between the surgeon and radiologist. Some mammographers will inject a biologic dye in to the breast parenchyma to assist localization. The surgeon reviews the films and localizes the abnormality with respect to the tip of the wire or needle. Alternatively, the surgeon will perform ultrasonography intraoperatively to directly localize the lesion. An incision is made directly over the abnormality, and a small portion of the breast tissue suspected of containing the abnormality is excised. For mammographically detected lesions, a specimen radiograph is obtained to ensure that the abnormality has been recovered. Often, the radiologist can place a needle in the specimen at the site of the abnormality to facilitate his to logic evaluation and ensure that the pathologist examines the site of the abnormality. Pathology and Natural His to ry Breast cancer may arise in the intermediate-size ducts, terminal ducts, or lobules. In most cases, the diagnosis of lobular and intraductal carcinoma is based more on his to logic appearance than site of origin. The cancer may be either in situ (ductal carcinoma in situ or lobular carcinoma in situ) or invasive (infiltrating ductal carcinoma, infiltrating lobular carcinoma). Morphologic subtypes of infiltrating ductal carcinoma include scirrhous, tubular, medullary, and mucinous carcinoma. True invasive ductal carcinoma accounts for 80% of all invasive tumors, with the final 20% split evenly between lobular carcinoma and special variants of infiltrating ductal carcinoma (24). Mammographically, invasive ductal cancers are characterized by a stellate density or microcalcifications. Macroscopically, gritty, chalky streaks are present within the tumor that most likely represent a desmoplastic response. Invasion of the surrounding stroma and fat, with a fibrotic, desmoplastic reaction surrounding the invasive carcinoma, generally is present. Special types of infiltrating ductal carcinoma are uncommon and typically account for nearly 10% of all invasive cancers. Medullary carcinoma, which accounts for 5% to 8% of breast carcinomas, arises from larger ducts within the breast and has a dense lymphocytic infiltrate. The tumor appears to be a slower growing and less-aggressive malignancy than other forms of carcinoma. Even when axillary disease is present, the prognosis with medullary carcinoma is better than that of other variants of invasive ductal carcinoma. Grossly, areas of the tumor may appear mucinous or gelatinous, whereas microscopically they are relatively acellular. Infiltrating comedo carcinoma accounts for less than 1% of all breast malignancies and is an invasive cancer characterized by foci of necrosis that exude a comedonecrosis-like substance when biopsied. Papillary carcinoma is predominantly a noninvasive ductal carcinoma; when invasive components are present, it should be specified as invasive papillary carcinoma. Tubular carcinoma, a well differentiated breast cancer that accounts for 1% to 2% of all malignant breast neoplasms, rarely metastasizes to axillary lymph nodes and tends to have a better prognosis than infiltrating ductal carcinoma. Adenoid cystic carcinomas are extremely rare breast tumors that his to logically are similar to those seen in the salivary glands. Growth Patterns the growth potential of breast cancer and the patient’s resistance to malignancy vary widely with the individual and the stage of disease. The doubling time of breast cancer ranges from several weeks for rapidly growing tumors to months or years for slowly growing lesions. If the doubling time of a breast tumor were constant and a tumor originated from one cell, a doubling time of 100 days would result in a 1-cm tumor in about 8 years (Fig. Because of the long preclinical tumor growth phase and the tendency of infiltrating lesions to metastasize early, many clinicians view breast cancer as a systemic disease at the time of diagnosis. Although cancer cells may be released from the tumor before diagnosis, variations in the tumor’s ability to grow in other organs and the host’s response to tumor cells may inhibit dissemination of the disease. Many women with breast cancer can be treated successfully with surgery alone, and some patients have been cured even in the presence of palpable axillary disease. A pessimistic attitude that breast cancer is systemic and incurable at diagnosis is unwarranted.
