Study Notes
Breast Lump - Differential Diagnosis and Workup
- Patient Presentation: A 45-year-old female with a progressively enlarging lump in the upper outer quadrant of her right breast for 6 months. She is concerned and presents to the surgical clinic.
Possible Diagnoses to Rule Out
- Breast Cancer: This is the primary concern given the presentation of a persistent, growing lump.
Diagnostic Approach
- Detailed History: Obtain a complete history, including family history of breast cancer, early menarche vs late menopause, use of hormonal therapies (OCPs, HRT). Assess risk factors such as obesity, and diet for understanding potential influence. Assess any prior radiation therapy.
- Physical Examination: Perform a thorough breast examination, noting the size, shape, consistency, location, and mobility of the lump and the skin overlying the area. Evaluate nipple/areola for any changes (retraction, discharge, skin changes). Assess for any associated skin changes (redness, puckering, dimpling).
- Imaging:
- Mammography: A cornerstone in breast cancer diagnostics, particularly for women over 40. If suspect a cancer, mammography will be done as early as possible.
- Ultrasound: Useful for differentiating solid from cystic masses or for further evaluation of the breast lump.
- MRI: Useful in certain cases , particularly for dense breasts.
- Biopsy: If the above imaging and physical examination are inconclusive, surgical biopsy or needle biopsy of the suspicious mass is indicated. This is the conclusive method for definitive diagnosis. Confirm a proper and reliable specimen/sample. It’s important to get the proper sample from a qualified person to avoid misdiagnosis.
Important Clinical Features (Breast Cancer)
- Location: Upper outer quadrant is a common location.
- Consistency: Often hard in consistency.
- Shape: Typically irregular in shape.
- Mobility/Fixity: Assess for fixation to skin or underlying structures.
- Skin Changes: Look for redness, dimpling, peau d'orange appearance (orange-peel texture) for signs of infiltration.
Other Important Considerations
- Benign Breast Conditions: Rule out benign breast conditions such as cysts or fibroadenomas.
- Risk Factors: Many factors, including genetics (BRCA1/2 mutations, p53 etc.), hormonal history, age.
- Inflammatory Breast Cancer: This rare but aggressive form may present with warmth to the touch.
Prognosis (and Late Features of Cancer):
- Features of poor nutritional status(anorexia/weight loss, anaemia, angular stomatitis, glossitis and ankles oedema) might be present in patients with advanced breast cancer
- Advanced disease could lead to weight loss , loss of appetite.
