The term breast mass is preferred over lump for a palpably discrete area of any size. A breast mass may be discovered by patients incidentally or during breast self-examination or by the clinician during routine physical examination. Masses may be painless or painful and are sometimes accompanied by nipple discharge or skin changes.
Benign and malignant characteristics of breast lesions at ultrasound allow the classification as either malignant, intermediate or benign based on work published by Stavros et al. In all cases of lesions other than those which are absolutely benign, real time review by the radiologist is mandatory. Review of the mammogram is essential when interpretation of an ultrasound is performed.

These glands are connected via a series of ducts that ultimately join up to form a common drainage path, terminating at the nipple. The nipple is surrounded by a ring of pigmented tissue known as the areola. Fibro-elastic and fatty tissue provide support for the rest of the structure and allow the breast to maintain its distinctive shape. The breast lies on top of the pectoral muscle, which in turn rests on the thoracic cage.
A benign breast condition is one that is not cancer. These problems often go away on their own or are easily treated. Because a few benign breast conditions can increase your risk of getting cancer in the future, you may need to have follow-up tests or exams with your obstetrician—gynecologist ob-gyn or other health care professional.
It also facilitates outcome monitoring and quality assessment. It contains a lexicon for standardized terminology descriptors for mammography, breast US and MRI, as well as chapters on Report Organization and Guidance Chapters for use in daily practice.

According to the ultrasonography lexicon of the Breast Imaging-Reporting and Data System of the American College of Radiology, 1 an echogenic breast lesion is defined as a lesion that is hyperechoic in comparison to the surrounding subcutaneous adipose tissue on ultrasonography. Echogenic breast lesions make up a small proportion 0. Stavros et al reported that hyperechogenicity was the feature with the highest Thus far, no data has been published regarding the incidence and histology of echogenic breast lesions in Singapore.
Breast cancer is cancer that develops from breast tissue. Risk factors for developing breast cancer include being female, obesitylack of physical exercise, drinking alcoholhormone replacement therapy during menopauseionizing radiationearly age at first menstruationhaving children late or not at all, older age, prior history of breast cancer, and family history. The balance of benefits versus harms of breast cancer screening is controversial.
A lump in the breast is a cause of great concern. High frequency, high-resolution USG helps in its evaluation. This is exemplified in women with dense breast tissue where USG is useful in detecting small breast cancers that are not seen on mammography. Several studies in the past have addressed the issue of differentiating benign from malignant lesions in the breast.
