Breast Fibroids: Symptoms, Causes & Treatment

Breast Fibroids

Finding a lump in your breast is very disturbing. Though it doesn’t always mean breast cancer, it can be overwhelming most of the time. At Njinsky Medical Centre, we understand how concerning this experience can be. That’s why our specialized team is available to evaluate your lump and provide you with a proper diagnosis with fully personalized treatment options.

Many women usually visit us due to concerns about breast fibroids. This medical condition is called fibroadenoma. It’s a benign breast lump made up of fibrous and glandular tissue. Unlike breast cancer, it does not spread to the surrounding tissues or other parts of the body.

Many women searching online for what are fibroids in breast are actually looking for information about fibroadenomas or other benign breast conditions. This guide explains everything you need to know about breast fibroids, including their symptoms, causes, types, diagnosis, and available treatment options.

Key Features of Breast Fibroids

It’s important to understand the key traits of breast fibroids. A typical fibroadenoma usually feels:

  • Smooth with well-defined edges
  • Firm or rubbery in texture
  • Round or oval in shape
  • Easily movable beneath the skin
  • Usually painless
  • Slow-growing

The Average Size of a Fibroadenoma

The size of most fibroadenomas is 1 to 3 cm. Some can be larger. The giant fibroadenomas are more than 5 centimeters and in rare cases can be removed surgically if they cause discomfort or change the shape of the breast.

Types of Fibroids in Breast

The following are the most common types of fibroids in breast. Explore them for a better understanding. 

Simple Fibroadenoma

  • Most common type
  • Uniform tissue, well-defined borders
  • Minimal risk of complications

Complex Fibroadenoma

  • Contains small cysts or calcifications
  • Harmless but slightly higher cancer risk
  • Requires closer monitoring

  Juvenile Fibroadenoma

  • Occurs in adolescents/young women
  • Grows quickly due to hormones
  • Typically, non-cancerous

Giant Fibroadenoma

  • Larger than 5 cm
  • May cause asymmetry, pain, cosmetic concerns
  • May need minimally invasive or surgical removal

Common Symptoms

Lump is smooth, round/oval, firm or rubbery and free to move, and slow growing but not usually painful.

Hormonal Effects

May increase in size during menstruation or pregnancy. It may decrease in size after menopause.

Additional Signs

Slight breast shape change and mild premenstrual tenderness. Temporary enlargement and fullness/pressure (if large) are observed.

 

Some Common Causes of Breast Fibroids

One of the most common questions our patients ask at Njinsky Medical Center is, “What causes breast fibroids?” While the exact cause is not fully understood, medical research suggests that fibroadenomas develop due to a combination of hormonal activity and genetics along with breast tissue changes.

Hormonal Changes

Growth and development of breast tissue are controlled by estrogen during puberty and reproductive years. Fibroadenomas are hormone-sensitive and they frequently develop in adolescence and young adulthood. They grow larger during pregnancy and become more noticeable just before menstruation. After menopause they shrink because of falling estrogen.

Age and Reproductive Years

Breast fibroids are most commonly diagnosed in women between the ages of 15 and 35. During these years, hormone levels are naturally higher, making fibroadenomas more likely to develop. They are less common after menopause.

Genetics and Family History

Breast fibroids can also be caused by genetics. Women with close relatives who have had fibroadenomas are slightly more likely to develop them.

Pregnancy and Hormonal Medications

An existing fibroadenoma may grow in size during pregnancy due to the large amounts of hormones present during this period. Likewise, some hormone drugs, such as oral contraceptives or hormone replacement therapy, can affect the size of a breast fibroid in some women.

How Breast Fibroids Are Diagnosed

The early diagnosis at Njinsky Medical Centre is crucial for giving patients peace of mind and confidence. Any new breast lump should be examined to see if it is a fibroadenoma or any other breast condition. Our breast specialists take a comprehensive approach to diagnosis which involves:

Medical History & Exam

  • Onset, size changes, pain
  • Family & hormonal history
  • Lump assessment (size, texture, mobility)

Breast Ultrasound

  • First test for younger women
  • Identifies solid vs fluid-filled lumps
  • Detects benign vs suspicious features

Mammography

  • Recommended for women 40+
  • Detects masses, calcifications, early cancer signs

Breast Biopsy (if needed)

  • Tissue sample for confirmation
  • Most accurate way to rule out cancer

The Best Time to Consult a Breast Specialist

Women are advised to undergo medical evaluation if they detect a new or changing breast lump. If you have any of these symptoms, make an appointment with the experts at Njinsky:

  • A newly discovered breast lump
  • A lump that continues to grow
  • Persistent breast pain
  • Bloody nipple discharge
  • Skin dimpling or nipple inversion
  • Swelling in the underarm area
  • Changes in breast shape or size

Breast Fibroid Treatment

At Njinsky Medical Centre, we understand that being diagnosed with a breast fibroid can raise many questions. Questions about treatment are very common and important. The good news is that most breast fibroids (fibroadenomas) are benign and do not require immediate removal. Our specialists develop personalized treatment plans based on the size of the lump and symptoms along with your overall health conditions and imaging results.

Do All Breast Fibroids Need Treatment?

No. Many fibroadenomas remain stable for years without causing complications. If a breast fibroid is small or not increasing in size, it does not need any treatment. No need to worry if it’s not causing pain or discomfort or if it’s confirmed benign through imaging or biopsy. Our breast specialists may recommend active surveillance instead of surgery in these cases. This approach involves routine clinical examinations and periodic imaging to ensure the lump remains stable.

Monitoring and Follow-Up

Breast health management involves having regular check-ups. At Njinsky, you get:

  •     Clinical breast examinations
  •     Follow-up breast ultrasounds
  •     Age appropriate mammograms according to risk factors.

Regular observation tracks any growth, development, or changes in size or appearance. In many cases, fibroadenomas may regress as a result of declining hormone levels following menopause, so surgery isn’t necessary.

Some of the Best Minimally Invasive Treatment Options

When treatment is needed, our specialists always aim to preserve healthy breast tissue while achieving the best possible cosmetic outcome.

Depending on the characteristics of your fibroadenoma, minimally invasive procedures may be considered. These include image-guided removal techniques. These methods require only a small incision and allow for a faster recovery than traditional surgery.

These procedures are suitable for selected patients and can effectively remove benign breast lumps with minimal scarring.

Surgical Removal

Surgery may be recommended if the breast fibroid:

  • Continues to grow
  • Is larger than 3–5 cm
  • Causes persistent pain
  • Alters the shape of the breast
  • Has uncertain imaging or biopsy findings
  • Causes significant emotional distress


Breast fibroid removal is typically performed as an outpatient procedure, allowing most patients to return home the same day. Our experienced surgeons focus on removing the lump while preserving the natural appearance of the breast whenever possible.

Noticing a lump in the breast is alarming. However, in most cases, it isn’t cancerous and doesn’t progress. One must have a complete knowledge of this condition to make an informed decision.

Is there a danger of breast fibroids being cancerous?

No. Breast fibroids, or “fibroadenomas,” are growths that aren’t cancerous and don’t spread to other areas of the body. However, all new breast lumps should be examined by a breast specialist to confirm the diagnosis.

Do breast fibroids go away?

Yes. Some fibroadenomas stay the same for years and others may slowly resolve or disappear. They usually resolve on their own after menopause when there’s less estrogen (the hormone produced by the ovaries).

Can a fibroid adenoma develop in the breast while I’m breastfeeding my child?

Yes, they can develop in most cases. Typically, they have no effect on breastfeeding or milk production.

Is there a chance to have breast fibroids again after surgery?

If one fibroadenoma is removed, another one can occur at a later time. Regular monitoring of the breast is important because some women may get new fibroadenomas because of continued hormonal influences.
