General Information

The majority of breast conditions are benign.

Benign lesions:

are not cancer,
do not necessarily progress to cancer,
and in most cases require monitoring rather than surgical treatment.

Proper clinical and imaging evaluation is essential for safe diagnosis.

Benign Breast Conditions

The majority of lesions detected in the breast are benign. The discovery of a nodule or the appearance of a symptom does not equate to a diagnosis of malignancy. The modern diagnostic approach allows safe and accurate differentiation between benign and malignant lesions, based on clinical assessment, imaging, and, where required, histological confirmation.

Fibroadenoma

Fibroadenoma is the most common benign solid lesion of the breast and occurs primarily in young women. It is a hormone-dependent lesion that typically presents as a well-defined, mobile mass with an elastic consistency and, in most cases, is painless.

Diagnosis is primarily based on ultrasound, where it displays a characteristic morphology. When there are diagnostic uncertainties or atypical features, a core needle biopsy is performed for histological confirmation.

Management is usually conservative, with follow-up when imaging features are typical and the size is stable. Surgical excision is indicated in cases of size increase, onset of symptoms, diagnostic uncertainty, or at the patient’s request.

Breast Cysts

Cysts are fluid-filled collections within the breast tissue and are particularly common in women aged 35-50. They are classified as simple or complex (or complicated), based on their ultrasound characteristics.

Simple cysts display clear and typical imaging findings and are not associated with an increased risk of malignancy. In most cases they are asymptomatic and do not require treatment. When they cause significant tension or pain, aspiration can be performed, which is a simple and immediately relieving procedure.

Complex cysts may require closer monitoring or further investigation, depending on their characteristics.

Fibrocystic Changes

Fibrocystic changes are hormone-dependent alterations in breast texture and are observed in a large percentage of women of reproductive age. They may be accompanied by cyclical breast pain, a nodular texture, or microcysts, especially before menstruation.

These are not a disease but a common normal variant. Management is conservative and primarily focuses on symptomatic relief when needed.

Mastalgia

Mastalgia, or breast pain, is a common symptom and is rarely associated with malignancy. It is classified as cyclical, when related to the menstrual cycle and caused by hormonal fluctuations, and non-cyclical, which may be related to local or musculoskeletal factors.

Evaluation includes clinical examination and, where indicated, imaging studies. In most cases, no specific treatment is required beyond reassurance and symptomatic management.

Nipple Discharge

Nipple discharge may be milky, clear, greenish, or bloody. In most cases, it is related to benign causes, such as intraductal papilloma or duct ectasia.

Particular investigation is required when the discharge is unilateral, spontaneous, and bloody. In such cases, targeted imaging and, if necessary, histological investigation is performed.

When is further investigation required?

Although most lesions are benign, indications for biopsy or closer monitoring include atypical imaging features, rapid size increase, discordance between clinical examination and imaging, or persistence of a suspicious finding.

The diagnostic approach is based on the principle of triple assessment: clinical examination, imaging, and histological confirmation where required. The combination of these three parameters ensures high diagnostic accuracy and a rational treatment strategy.

What you should know

Finding a nodule does not mean cancer. The majority of women who undergo evaluation for a palpable finding will ultimately receive a benign diagnosis.

Timely and systematic evaluation reduces anxiety, prevents delayed diagnosis where necessary, and ensures safe and personalized management. Knowledge and proper medical guidance are the most powerful tools for managing any finding.
