Palpable breast masses are customa...

Palpable breast masses are customary and usually benign, but efficient evaluation and apt diagnosis are necessary to government out malignancy. A thorough clinical breast examination, imaging, and tissue sampling are wanted for a definitive diagnosis. Fine-needle aspiration is fast, inexpensive, and accurate, and it can differentiate solid and cystic masses. However, physicians must have adequate training to perform this manner of proceeding Mammography screens for occult malignancy in the same and contralateral breast and can ascertain malignant lesions in older women; it is les sensitive in women younger than 40 years. Ultrasonography can expose cystic masses, which are for the use of all and may be used to guide biopsy techniques. Tissue specimens obtained with core-needle biopsy allow histologic diagnosis, hormone-receptor testing, and differentiation between in situ and invasive disease. Core-needle biopsy is more invasive than fine-needle aspiration, requires more training and experience, and many times requires imaging guidance. After the clinical breast examination is performed, the evaluation be pendents largely on the patient's age and examination characteristics, and the physician's experience in performing fine-needle aspiration.

**********

Breast carcinoma masses have a variety of etiologies, benign and malignant. Fibroadenoma is the most numerous common benign breast mass; invasive ductal is the in the greatest degree common malignancy. (1) Most masses are benign, on the other hand breast cancer is the most numerous common cancer and the inferior leading cause of cancer deaths in women (2) Although greatest in number breast cancers occur in women older than 50 years, 31 percent of women diagnosed with breast cancer between 1996 and 2000 were younger than 50 years. (3) An efficient and accurate evaluation can maximize cancer detection and minimize unnecessary testing and procedures

Initial Evaluation

HISTORY

A thorough patient history is necessary for the physician to identify risk factors for breast cancer. a certain number of risk factors are well established, and others indicate probable or possible increased risk (Tables 1 and 2) (4-14)

PHYSICAL EXAMINATION

A whole clinical breast examination (CBE) includes an assessment of the two breasts and the chest, axillae, and regional lymphatics. In pre-menopausal women the CBE is best done the week following mense when breast tissue is least engorged. With the patient in an upright position, the physician visually inspects the breasts, noting asymmetry, nipple discharge, obvious masses, and skin changes, as it is as dimpling, inflammation, rashes, and unilateral nipple retraction or inversion. (15)

With the patient supine and single arm raised, the physician thoroughly palpates breast tissue forward the raised-arm side in the superficial, intermediate, and penetrating tissue planes (i.e., the "triple touch" technique); axilla; supraclavicular area; neck; and chest wall, assessing the size, tissue and location of any masses (Figure 1) (15) The physician should note the size of the masses to document changes throughout time. Next, the physician should inspect the areola-nipple manifold for any discharge. CBE sensitivity can be improved at longer duration (i.e., five to 10 minutes) and increased precision (i.e., using a systematic pattern, varying palpation urgency and using three finger pads and circular motions). (1516)

Benign masses generally cause no skin change and are sleek soft to firm, and mobile, with well-defined margins. Diffuse, symmetric thickening, which is used by all in the upper outer quadrants, may indicate fibro-cystic changes. Malignant masses generally are hard, immobile, and fixed to surrounding skin and smooth tissue, with poorly defined or irregular margins. (15) However, mobile or nonfixed masses can be cancerous. Infections of that kind as mastitis and cellulitis mind to be erythematous, tender, and warm to the touch; they may be more circumscribed if an abscess has formed. Similar symptoms may present itself in patients with inflammatory breast cancer. Therefore, caution should be used in assessing patients with suspected breast infections.

Digital palpation of the breast is effective in detecting masses and can help determine whether a mass is benign or malignant. (1517) CBE can ascertain up to 44 percent of cancers, up to 29 percent of which would not have been exposeed by mammography. (15,17) Despite its accuracy, CBE alone is not adequate for definitive diagnosis of breast cancer. Further evaluation, including follow-up examinations, imaging, and tissue sampling, is required in all patients with breast masses.

Imaging

ULTRASONOGRAPHY

Ultrasonography can effectively distinguish solid masses from pouchs which account for approximately 25 percent of breast lesions. (1819) When strict criteria for pouch diagnosis are met, ultrasonography has a sensitivity of 89 percent and a specificity of 78 percent in detecting abnormalities in symptomatic women (18) intermittent or complex cysts may signal malignancy; therefore, further evaluation of these lesions is required.
