Radial Scar - Causes, Diagnosis, and Treatment

What Are Radial Scars?

Radial scars are usually benign tumors that can look like malignant scars. It is most commonly observed in middle-aged women. It is also known as a radical mammary scar, the stellate scar of the breast, and infiltrating epitheliosis. Middle-aged are at greater risk of developing cancer.

What Causes Radial Scar of Breast?

Various studies have shown the predominance of hormones associated with the radial scar. In addition, the mutations of genes seen at the cellular level can cause alterations leading to a radial scar. However, the exact cause of these abnormalities is still unknown.

How Do Radial Scars Look?

Radial scar gives a characteristic ‘star-like’ appearance. They are present in the round, oval, and translucent forms. It is often seen as a black star. The lesion shows sclerosing papillary proliferation, infiltrating epitheliosis, and indurative mastopathy.

Do Radial Scars Exhibit Symptoms?

They are usually asymptomatic as they do not produce discoloration or solid lumps on palpitation. Hence, the diagnosis is confirmed in mammogram and biopsy studies. Usually, the tumors occur in both breasts. The breast lumps are painless and might present as a large mass, irregular and firm, resembling a carcinoma. Radial tumors may be seen around five millimeters in size. Cancer shows a distinctive pattern under microscopic study. The presence of radial tumors is highly susceptible to cancer of the breast. However, cancer risk depends on the person’s age, tumor site, and extent of cancer. Radial scars are usually benign and have a good prognosis.

How Is Radial Scar Formed?

They are caused due to hyperplasia (increase in the number of cells) of the sclerosing duct, atypia (change in the cell characteristics), and precancerous tumors. In addition, the risk factors may include gender preference, which is seen more commonly in women than men. Other risk factors include the consumption of birth control pills, obesity, and one’s reproductive history.

What Are the Diagnostic Tools to Detect Radial Scars?

Some of the tests present to check for radial scars are:

• Physical Examination: Checking for any abnormal lumps.

• Mammogram: A mammogram is an X-ray image of the breast. It is difficult to detect a radial scar under a mammogram.

• Ultrasound: The ultrasound evaluation also does not show a cancerous lesion of the radial tumor. It is used to evaluate any solid-filled cyst or fluid-filled cyst.

• Magnetic Resonance Imaging (MRI) With Contrast: It is used to collect images of the breast with high resolution.

• Core Needle Biopsy: Because mammography and ultrasonography are unable to rule out the existence of malignant tissue in radial scars, everyone who has one should undergo a biopsy. On mammography, a big radial scar may resemble breast cancer. Even with a biopsy, it can be challenging to correctly identify a radial scar since, under a microscope, the cell geometry closely matches that of tubular carcinoma. There may be cancerous tissue hidden behind this breast lump, which is normally benign. A wider needle is used in a core biopsy to extract a small cylinder of tissue from the lesion site. Other studies like immunohistochemical stains and molecular studies are undertaken with biopsies to confirm the diagnosis. The biopsy is the only tool to rule out the condition from benign to malignant. Other biopsy studies, such as fine needle aspiration (FNAB) and open tissue biopsy of breast mass are also performed.

Who Are at Greater Risk of Developing Radial Scar?

Many factors can contribute to the development of radial scars. Such as:

• Middle-Aged Women: Women between the age group of 30 to 50 years are at higher risk.

• Familial: This leads to genetic mutations more easily.

• Obesity: Being overweight can increase the risk of developing a radial tumor.

• Alcohol Consumption: Unhealthy lifestyle can bring serious consequences to health.

• Early Menstruation: Women who get periods before the age of 12 years are at risk.

• Late Menopause: Women having menopause after the age of 55 years can develop a radial scar. The longer the distance between menarche and menopause, the greater the risk. This is due to the hormonal changes seen during the reproductive phases of breast tissue.

• Postmenopausal Hormonal Therapy: Women taking estrogen and progesterone tablets are at a higher risk of developing radial scars.

• Infertile Women.

• Delayed Conception: Women having their first child after the age of 35 years.

• Sedentary Lifestyle: Lack of locomotive functions resulting in abnormal metabolic activity of the body.

The presence of risk factors does not imply that one would get a radial scar. But they are on the higher end of developing the condition. Always discuss the condition with a healthcare worker. Any disturbing symptoms present can be treated based on the symptoms.

What Are the Treatments Available for Radial Scars?

The treatment for radial scars depends mainly on the progression and size of the scar.

Surgery: Even in non-invasive forms, surgical removal of the tissue is recommended. This may be done with an open surgical incision or a lumpectomy. These are done under general anesthesia. After the incision, a hollow probe is inserted into the tissue to suck out all the hyperplastic cells present. This is done using a vacuum. If the tissue contains malignant proliferating cells upon microscopic examination, it is further advised to undergo higher treatment options. Treatments such as radiation, chemotherapy, and hormonal replacement therapy are done.

What Are the Preventive Measures Against Radial Scar?

Early detection is of foremost importance. If individuals are detected with a radial scar, they must be extra vigilant about their breast health. Proper lifestyle changes must be adopted, like avoiding anti-cancer diets, taking regular exercise, and lowering stress levels are minor changes. They should avoid any bad habits if present, like smoking and alcohol consumption. The limited use of hormone therapy is advised.

Conclusion:

There are no preventive measures against radial scars. Every one in eight women is at risk of developing radial cancer. People who are at high risk of developing radial scars are the ones who have a family history. Therefore, they should regularly follow up with a doctor and perform proper screening tests on time.
