Name of the Condition

• Unspecified lump in left breast, subareolar (ICD Code: N63.42)

Summary

A lump in the subareolar region of the left breast refers to an unidentified mass located beneath the areola. While often benign, it requires medical evaluation to rule out serious conditions, such as breast cancer.

Causes

• Hormonal changes, such as those occurring during menstrual cycles.
• Benign breast conditions like fibroadenomas or cysts.
• Infections that cause abscesses or other inflammatory responses.
• Malignant growths, though less common, can occur.

Risk Factors

• Female gender, as breast lumps are more frequent in women.
• Age, particularly post-adolescence to menopause, when hormonal changes are common.
• Family history of breast conditions or breast cancer.
• Previous breast lumps or breast conditions.

Symptoms

• Noticeable lump under the areola of the left breast.
• Possible tenderness or pain in the area.
• Changes in the size or shape of the breast or areola.
• Discharge from the nipple might occur in some cases.

Diagnosis

• Physical examination by a healthcare provider.
• Imaging tests such as mammography or ultrasound.
• Biopsy may be conducted to determine the nature of the lump.

Treatment Options

• Monitoring for changes in size or symptoms if benign.
• Surgical removal for persistent or uncomfortable lumps.
• Medications or antibiotics in case of infection.
• Radiation or chemotherapy, if malignancy is detected.

Prognosis and Follow-Up

• Benign lumps often pose minimal risk but require monitoring.
• Early detection and treatment of malignancies can improve outcomes.
• Regular follow-ups are essential to monitor any changes in the condition.

Complications

• Untreated infection can lead to abscess formation.
• Malignancies can advance, impacting overall breast health.

Lifestyle & Prevention

• Regular self-examinations to detect lumps early.
• Maintain a healthy lifestyle with a balanced diet and regular exercise.
• Limit alcohol consumption and avoid smoking.

When to Seek Professional Help

• Discovery of a new lump or change in an existing lump.
• Persistent pain or discomfort in the breast.
• Any nipple discharge, particularly if bloody or unusual.
