What is a circumscribed mass in breast?

What does a mass with circumscribed margins mean?

As defined in the US lexicon (1), circumscribed margins are well defined or sharp, with an abrupt transition between the lesion and the surrounding tissue. Noncircumscribed margins encompass the remaining margin descriptors, including microlobulated, indistinct, angular, and spiculated.

What is the term for a circumscribed mass of tissue?

Benign masses are often round or oval with circumscribed margins. Malignant lesions tend to have irregular, indistinct, or spiculated margins. Malignancies tend to have density greater than that of the normal breast tissue.

Can benign tumors have irregular borders?

Many benign breast diseases present with irregular hypoechoic masses that can mimic carcinoma on ultrasonography. Some of these diseases such as inflammation and trauma-related breast lesions could be suspected from a patient’s symptoms and personal history.

Can a circumscribed mass be malignant?

The likelihood of malignancy with a circumscribed mass is very low, but additional work-up may be necessary to verify that the margins are completely circumscribed. Typical examples of benign circumscribed masses are cysts (Figure 36f-5) and fibroadenomas (Figure 36f-6).

What is a stable mass?

Cancer doctors use the term stable disease to describe a tumor that is neither growing nor shrinking. Specifically, it means that there was neither an increase in size of more than 20% nor a decrease in size of more than 30% since the initial baseline measurement.

Can an irregular breast mass be benign?

You or your doctor might be able to feel a lump or see nipple discharge, or your mammogram might pick up something that requires further testing. Any abnormal change in the breast can be a sign of cancer and needs to be checked out. However, many changes turn out to be benign.

A breast lump that’s painless, hard, irregularly shaped and different from surrounding breast tissue might be breast cancer. Skin covering the lump may look red, dimpled or pitted like the skin of an orange. Your breast size and shape may change, or you may notice discharge from the nipple.

Should all breast masses be biopsied?

If a lump is proven to be benign by its appearance on these exams, no further steps may need to be taken. Your doctor may want to monitor the area at future visits to check if the breast lump has changed, grown or gone away. If these tests do not clearly show that the lump is benign, a biopsy may be necessary.

What is hypoechoic mass in breast?

What does circumscribed margins mean?

What does that mean? This means that you have moderately dense tissue, which is common and not a cause for concern. Sometimes, dense tissue can make it difficult to accurately read a mammogram. You and your doctor can discuss options for supplemental screening (i.e. screening method in addition to a mammogram), if necessary.

What is a small stable circumscribed mass?

The shapes of masses that are circumscribed may be round, oval, or lobular. The margination that is described as “circumscribed” allows one to visualize a fine, clear edge around the entire mass. Often masses that are circumscribed may be overlapped by parenchyma in some areas. These are described as obscured or partially circumscribed.

What does well circumscribed mean?

What does well circumscribed mass mean? Circumscribed masses. A circumscribed mass in mammography is a mass where the contour is clearly defined along at least 75% of its surface. The remaining 25% may, at most, be masked by the adjacent gland. Circumscribed masses first indicate benign lesions.
