Fibroadenoma: What it is, symptoms, and when to seek a doctor

• January 28, 2025
• By Fernando Amato

Fibroadenoma is one of the most common types of benign breast tumors, especially frequent in young women. Although it generally does not pose a life threat, diagnosis and medical follow-up are essential to ensure breast health and rule out other conditions.

In this article, we will discuss what fibroadenoma is, its main symptoms, how it is diagnosed, and when it is necessary to seek a specialist doctor.

📝 Highlights on the topic

✅ Fibroadenomas are benign breast tumors, most common in young women.

✅ They are usually painless, mobile, and have a firm consistency.

✅ They can be diagnosed by clinical examination, ultrasound, or mammography.

✅ Most do not require surgical treatment, but medical follow-up is essential.

✅ Changes in size or atypical symptoms should be evaluated urgently.

What is fibroadenoma?

Fibroadenoma is a non-cancerous tumor that forms in the breast due to the abnormal growth of glandular and connective tissue. It is considered benign because it does not spread to other parts of the body. It is most common in women between 15 and 35 years old, but can occur at any age.

This tumor has specific characteristics:

• Mobile to the touch: It can usually be moved under the skin when palpated.

• Rounded or oval shape: It generally has well-defined borders.

• Painless: In most cases, it does not cause discomfort or pain.

Despite being benign, fibroadenoma should be evaluated by a doctor, especially because some malignant conditions can have similar characteristics.

What are the symptoms of fibroadenoma?

Many women discover fibroadenoma during breast self-examination or routine check-ups. Although it is generally asymptomatic, the most common signs include:

• Presence of a firm, mobile nodule in the breast, with a rubbery texture.

• Absence of pain, although some women report slight tenderness in the area.

• Increase in nodule size during specific hormonal periods, such as before menstruation or during pregnancy.

Most of the time, fibroadenoma is solitary, but multiple nodules can occur in one or both breasts.

Causes of fibroadenoma

The exact cause of fibroadenoma is not yet fully understood, but it is believed to be related to hormonal changes, especially estrogen, a female hormone that regulates breast development and function.

Factors that may influence the appearance of fibroadenoma:

• Young age (especially during reproductive phase).

• Family history of fibroadenomas or other breast conditions.

• Use of hormonal contraceptives at an early age.

How is the diagnosis made?

The diagnosis of fibroadenoma usually begins with a clinical examination, in which the doctor performs breast palpation. If suspicion arises, additional tests may be requested to confirm the nature of the nodule.

1. Breast ultrasound

• Ideal for younger women, as the density of breast tissue makes mammographic analysis difficult.

• Allows evaluation of whether the nodule is solid (as in fibroadenoma) or cystic (filled with fluid).

2. Mammography

• More common in women over 40 or in specific cases.

• Helps identify the size, shape, and location of the nodule.

3. Biopsy

• In cases of doubt, a fine-needle aspiration or core biopsy may be performed to collect a tissue sample. Histopathological examination will confirm whether the nodule is benign or malignant.

When does fibroadenoma need to be treated?

In most cases, fibroadenoma does not require treatment, only periodic follow-up with clinical and imaging examinations. However, removal may be indicated in some situations, such as:

• Accelerated nodule growth or size greater than 2-3 cm.

• Presence of pain or discomfort.

• Suspicious changes in imaging tests.

• Patient preference for aesthetic or emotional reasons.

The most common procedure for removal is lumpectomy, a simple and low-risk surgery.

Can fibroadenoma turn into cancer?

Fibroadenoma is a benign tumor and, by itself, does not transform into cancer. However, there is a rare type called complex fibroadenoma, which may be associated with a slightly higher risk of developing breast cancer in the future.

Therefore, regular medical follow-up is essential, especially in cases of fibroadenomas with atypical characteristics.

Prevention and breast health care

Although it is not possible to completely prevent the appearance of fibroadenomas, some practices can help with overall breast health:

• Perform monthly self-examination, preferably after the menstrual period.

• Maintain regular consultations with a doctor, including imaging tests as recommended.

• Adopt a healthy lifestyle, including a balanced diet and regular physical exercise.

• Avoid smoking and excessive alcohol consumption, which are associated with general health risks.

Remember: any changes in the breasts should be evaluated by a specialist.

Conclusion

Fibroadenoma is a benign tumor that does not pose a direct health risk, but requires attention and medical follow-up to ensure breast health is in order. If you notice any changes in your breasts or have questions, schedule an appointment with a specialist for an accurate diagnosis and an appropriate follow-up plan.
