Breast Surgery Case history Doctor asks patient about any changes in breast during the menstrual cycle (painful, tender ), if she has periods. Are there any swellings or lumps, which she noticed , any changes or discharge from the nipple. Did she breast feed her children. Did her mother or sister suffer from breast cancer. Physical examination of the breast. 1. Woman must take off her clothes and bra to palpate breast and detect any lumps. 2. She rests both hands on her lap. 3. She presses both hands firmly on her hips. 4. She raises both arms above her head. 5. She leans forward so that her breast become pendulous ( look for “dimpling”). 6. She places her forearm on doctor’s forearm and doctor feels under her armpit. 7. Doctor feels supraclavicular fossa ( standing behind the patient). 8. Woman lies on the couch and doctor uses flat of fingers not the tips to detect any lumps. Incidence of breast mass lesions Non neoplastic 55% Neoplastic 45% Cystic disease 40% Duct ectasia 2% Gynecomastia 5% Inflammatory 5% Fibroadenoma 6% Duct papilloma 3% Carcinoma 35% Other 4% -Gynecomastia- enlargement of the breast in the male ( sometimes in Klinefelter syndrome). -Fibrocystic disease (chronic cystic mastitis)- epithelial and stromal proliferation, repeated hypertrophy in response to stimulation by estrogen, progestin and prolactin. Fibrocystic disease is a risk factor for breast cancer. -Mammary Duct Ectasia- disease of involuting breast. The collecting ducts in the subareolar area are dilated and filled with cellular debris. -Fibroadenoma- the most common tumor in women under 25 years of age.Treatment consists of enucleation. -Cystosarcoma phyllodes (leaflike)- it is not cystic tumor and in majority is not malignant. Enucleation may lead to recurrence so it should be removed with rim of surrounding breast tissue. It may manifest a malignant behavior when there is local invasion. Metastases occur in about 10% of cases and are bloodborne. Regional node dissection is not indicated because lymph nodes are not involved. -Intraductal papilloma- tumor is 1 to 2mm in diameter and bleeds easily. The hallmark is serous or bloody discharge from nipple. When it is 3 to 4mm in diameter can be palpable. Diffuse process is called papillomatosis. The incidence of malignancy is increased. -Inflammatory processes- Acute mastitis as diffuse streptococcal cellulites or abscess due to staphylococcal infection. Mondor disease- thrombophlebitis of superficial thoracoepigastric vein. Screening Self-examination of the breast by all women at least monthly. Visit a doctor once a year. First mammography is recommended after 40 years of age. (Every 1-2 year). An annual mammogram is indicated when there is a strong family history of breast cancer or previously treated for breast cancer and post menopausal women. Breast ultrasound, CT scan or magnetic resonance imaging MRI are not applied in screening. They only complete mammography and palpable examination. Ultrasound can diagnose a cyst but not distinguish benign from malignant solid lesions. Cytological examination can be performed on fluid aspirated from cyst. Nipple discharge is placed on a slide and fixed as for Papanicolaou smear. Thin needle biopsy should be performed on a solid mass in the breast during ultrasound . When the result is positive it is an excellent means to diagnose breast cancer. Negative result can not rule out cancer so open biopsy must be performed. Open biopsy of mass in the breast may be excisional or incisional. Diagnostic accuracy is almost 100%. Excisional biopsy may be both diagnostic and therapeutic in the case of benign tumor. When solid lesion is greater than 4 cm in diameter an incisional biopsy by knife or biopsy forceps is performed. Depending on frozen section biopsy and final diagnosis further tissue is removed. Special strategy is required for biopsy of a lesion which is detected on mammography but is not palpable. A wire with hook is passed into area of the tumor with radiographic control and next wire with rim of tissue is excised. That method is very helpful in case of microcalcification aggregation because cancer in situ is in 20% of them. Methylene blue (dye) labeling is applied for localization tumor which is not palpable but detected in ultrasound examination. The ability of breast tumor cells to bind sex steroids: both estrogen ER+ (two third of breast cancer) and progesterone PR+ should be established in all cases of malignancy. This information is important in selection of subsequent therapy. The Breast Cancer The breast is the most frequent site of cancer among women. Approximately 90,000 new cases of breast cancer are diagnosed annually in the USA and almost 40,000 die of breast cancer each year. In Poland new incidence of disease is about 10,000 annually (19% of all neoplasms in women) and 4,500 women die of breast cancer. Breast cancer is more likely in white than black women and more often in western culture. The cause of breast cancer is unknown but factors: hereditary, biologic and environmental are known or suspected: Strong family history of breast cancer, nulliparous women, menarche before age of 12, late menopause administration of reserpine. Pathology It may arise from cells lining the ducts or from cells in the breast lobule. 1.Paget’s disease of the nipple. Adenocarcinoma of the breast in which the tumor cells invade the nipple. 2.Duct cell origin- 75% of cases of breast cancer. A. In situ ( noninfiltrating, intraductal DCIS) B. Infiltrating -scirrhous (predominates) -medullary -comedo -papillary -colloid -tubular 3.Lobular origin A. In situ LCIS B. Infiltrating Slightly more favorable prognosis than ductal ca. The majority of women with lobular ca in one breast will have ca in opposite breast. Inflammatory cancer Specific type of tumor highly aggressive and invades the dermal lymphatics. Redness includes one third of breast, positive result thin needle biopsy and painful. Male breast cancer less than 1% of breast cancer. Bilateral breast cancer- synchronic or metachronic in about 7% of cases. Breast cancer metastasizes lymphborne and secondary bloodborne to lymphnodes 60%, Lungs 55%, bones 50%, liver 50%, skin 35%, ovaries 12% and brain 10%.

Extended excision- tumor is removed with 1cm margin of tissue. Quadrantectomy- tumor is removed with at least 2cm margin. It does not mean that one fourth of breast is removed. Simple mastectomy- entire breast is removed with pectoral fascia. Madden modified radical mastectomyremoval of entire breast, pectoral fascia and ipsilateral axillar contents. Patey modified radical mastectomy- Madden mastectomy and removal of pectoris minor muscle. Halsted radical mastectomy- removal of entire breast with pectoris major muscle and axillar lymphadenectomy. Sentinel node biopsy-removal first axillar node after radioisotope labeling and dye labeling. In case of positive node radical lymphadenectomy is indicated.
