About Radial Scars of the Breast:
A radial scar is a star-shaped breast mass that may be completely benign, or it may be precancerous or contain a mixture of tissue, including hyperplasia
, or cancer. If a radial scar is rather large
, it may
appear on a regular screening mammogram
. It can look like an irregularly shaped star, having spiked arms radiating away from the center. A radial scar in breast tissue usually won't
cause a lump that you can feel, nor will it make breast skin dimple or discolor. In some cases, a radial scar may cause some breast pain
Also Known As:
Complex sclerosing lesion of the breast, black star, sclerosing papillary proliferation, infiltrating epitheliosis and indurative mastopathy
Radial Scars of the Breast Are Rare:
An estimated 0.04%, or six out of every 15,000 patients are diagnosed annually with a radial scar of the breast. Women between the ages of 41 and 60 are at the highest risk for a radial scar. These breast lesions are even less common in women under 40 or over 60 years old.
Significance of a Radial Scar Diagnosis:
Having a radial scar causes concern because a large one looks like breast cancer
when seen on a mammogram. It is difficult to properly diagnose a radial scar, even with a biopsy, because under a microscope, the cell geometry closely resembles tubular carcinoma
. This typically benign breast mass sometimes
has malignant tissue hiding behind it.
Increased Risk For Breast Cancer:
If you have been diagnosed with a radial scar, then your lifetime risk for developing breast cancer is 150 to 200% greater than average. Many patients have extra screening mammograms to document any breast changes. Some women may choose a lumpectomy
to remove the suspicious tissue.
Causes of a Radial Scar in Your Breast:
A radial scar is not always made of scar tissue, but it takes its name from its scar-like appearance on an x-ray. A radial scar may be caused by breast surgery, or breast inflammation
or hormonal changes. It may also be the byproduct of fibrocystic changes
in the breast that normally occur as you age.
Tests Used to Diagnose Radial Scar:
You may not need all of these tests, but you must have a biopsy
so a pathologist can examine the tissue, to get a clear diagnosis.
Treatment For Radial Scar:
You may have options for radial scar treatment. Many doctors advise patients to have this breast mass surgically removed, in order to prevent a possible malignancy from forming. This may be done with an open surgical biopsy
or a lumpectomy
, depending on the size of the radial scar. The tissue from your surgery will be examined and tested in a lab. If your radial scar did not
contain any invasive breast cancer cells, you won't need radiation
, or hormonal therapy
as follow-up treatments.
Make Healthy Choices to Keep Your Breast Cancer Risk Low:
However, if you have a low risk of having a malignancy, then your doctor may suggest being extra vigilant about your breast health. Keep your risk of breast cancer low by sticking to an anticancer diet
, doing regular exercise
, keeping slim, and lowering your stress levels
. Avoid using alcohol
to protect your overall health.
