What can a breast mass be besides cancer?

There are many possible causes of non-cancerous (benign) breast lumps. Two of the most common causes of benign single breast lumps are cysts and fibroadenomas. In addition, several other conditions can present themselves as lumps, such as fat necrosis and sclerosing adenosis.

Which type of breast mass is a form of breast cancer?

Invasive (or infiltrating) breast cancer has spread into surrounding breast tissue. The most common types are invasive ductal carcinoma and invasive lobular carcinoma. Invasive ductal carcinoma makes up about 70-80% of all breast cancers.

What is the most common benign breast mass?

Fibroadenomas occur in 25% of women; they are the most common benign tumors of the breast and do not require treatment.

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.

Can a radiologist tell if a lump is cancer?

Some masses can be watched over time with regular mammograms or ultrasound to see if they change, but others may need to be checked with a biopsy. The size, shape, and margins (edges) of the mass can help the radiologist decide how likely it is to be cancer.

How can you tell the difference between a fibroadenoma and breast cancer?

Unlike a breast cancer, which grows larger over time and can spread to other organs, a fibroadenoma remains in the breast tissue. They’re pretty small, too. Most are only 1 or 2 centimeters in size. It’s very rare for them to get larger than 5 centimeters across.

What area of the breast are most cancers found?

(Eighteen percent of breast cancers occur in the nipple area, 11 percent in the lower out quadrant, and 6 percent in the lower inner quadrant.) ANY change in size, shape, texture or nipple that occurs in one breast only is more dangerous than if such changes happen simultaneously in both breasts in the same position.

What’s the difference between a mass and a tumor?

Mass – A quantity of material, such as cells, that unite or adhere to each other. Tumor – 1. A swelling or enlargement (tumor is Latin for swelling).

Can fibroadenoma look like cancer on ultrasound?

While it is difficult to distinguish between the different benign fibroepithelial lesions on imaging, it can also be challenging to distinguish between fibroadenomas and malignant masses. Ultrasound features of BRCA-associated breast cancers can resemble a benign mass, such as a fibroadenoma.
