N63.23 Unspecified lump in the left breast, lower outer quadrant

ICD10CM code

#### Name of the Condition
- Unspecified Lump in the Left Breast, Lower Outer Quadrant
- Also referred to as breast lump in medical terminology.

#### Summary
- An unspecified lump in the left breast's lower outer quadrant is a palpable mass where the exact type is not determined. It's important to evaluate as lumps in the breast can range from benign cysts to malignant tumors.

#### Causes
- The exact cause of a breast lump can vary. Common causes include benign fibrocystic changes, cysts, fibroadenomas, or potentially breast cancer.

#### Risk Factors
- Risk factors may include gender (female), increasing age, personal or family history of breast cancer, hormonal factors, and lifestyle choices, such as alcohol consumption.

#### Symptoms
- Presence of a palpable lump or mass in the breast.
- Possible changes in breast shape or size.
- Swelling or tenderness in the breast region.
  
#### Diagnosis
- Physical examination by a healthcare provider.
- Imaging tests like mammograms or ultrasounds.
- Biopsy to rule out or confirm cancerous cells.

#### Treatment Options
- Treatment depends on the diagnosis. For benign lumps, monitoring and observation may be sufficient.
- Surgical removal may be necessary for persistent or suspicious lumps.
- If malignancy is confirmed, treatment might include surgery, chemotherapy, or radiation therapy.

#### Prognosis and Follow-Up
- Prognosis depends on the underlying nature of the lump. Benign conditions generally have a favorable outcome.
- Regular follow-up is crucial, particularly if the lump changes characteristics or if there is a family history of breast cancer.

#### Complications
- Potential complications include anxiety over the unknown nature of the lump and, if malignant, metastatic spread.

#### Lifestyle & Prevention
- Maintain a healthy lifestyle with a balanced diet and regular exercise.
- Routine self-examinations and regular screening as recommended, especially if at higher risk.

#### When to Seek Professional Help
- Seek medical attention if you detect a new lump, significant changes in an existing lump, or skin changes.
