Q

Diagnosis of Breast Ca

A
  1. History and Clinical Examination
  2. Imaging
    - Breast screening (50-70 every 3 years) – early detection
    - Mammography
    - USS – better for denser breast tissue (younger patients)
    2 week wait criteria
  3. Pathology FNAC + Core biopsy

Q

Staging of Breast cancer

A

Staging
- Histopathology – most are derived from epithelium lining of ducts/lobules (ductal/lobular carcinoma)

Grading
- Appearance of breast Ca cells compared to normal tissue

TMN Staging

  • Stage 0 = in situ, Paget’s disease of the breast, DCIS
  • Stage 1-3 = within breast, regions LNs
  • Stage 4 = metastatic cancer

Q

Mx of Breast cancer

A
  1. SURGERY
    - Removal of tumour and surrounding LNs
    - Mastectomy, lumpectomy, quadrantectomy
    - Breast reconstruction surgery
  2. MEDICATION
    - ER antagonists e.g. tamoxifen
    - Aromatase inhibitors e.g. letrozole
  3. CHEMOTHERAPY
    - Cyclophosphamide, doxorubicin
  4. MONOCLONAL ANTIBODIES
    - Trastuzumab (HER2)
  5. RADIATION
    Post surgery, reduces risk of recurrence
17
Q
4. Risk factors for developing breast cancer include:
A. Having only one child
B. Early menarche 
C. Early menopause
D. Anaemia
E. HIV/AIDS
A

B. Early menarche

18
Q
  1. A 56 year old woman presents to her GP after noticing a breast lump 3 weeks ago. On examination, the lump is 3 cm in diameter, firm and tethered to the skin and immobile. There are no overlying skin changes. The next most appropriate investigation is:
A. Total mastectomy
B. Urgent mammogram
C. Urgent USS
D. FNAC
E. Core biopsy
A

B. Urgent mammogram

19
Q
  1. A 22 year old medical student presents to her GP complaining of ‘lumpiness’ in her breasts and nipple discharge for 2 weeks. She is concerned as her mother, who had breast cancer, had the same symptoms before she was diagnosed. What is the next most appropriate investigation?
A. Refer for urgent mammogram
B. Refer for urgent USS
C. Blood hCG levels
D. Reassure and discharge  
E. CT Head
A

C. Blood hCG levels

Why CT head? To rule out prolactinoma

20
Q

Mastitis/Breast abscess

Definition and Epidemiology

A

Mastitis = inflammation of the breast (Pathology = Straph and Strep infection)
Rare complication: can lead to formation of a breast abscess = collection of pus within the tissue.

Epidemiology:

  1. Breastfeeding women – milk stasis(poor breastfeeding technique)
  2. Immunocompromised – HIV/AIDS, diabetes, chronic illness
  3. Primiparous (given birth to 1 child)
  4. Over 30 years old
21
Q

Mastitis/Breast abscess Signs and Symptoms, Invx

A

S: generalised swelling of the breastC: redness, firmT: very tender, warm to touchF: flu like symptoms - fever, aches, fatigue, chills

Ix:

  • Clinical diagnosis
  • USSto distinguish tumour and abscess
  • Biopsy (women not responding to treatment, or non puerperal mastitis)
22
Q

Mastitis/Breast abscess Mx

A

Management of Mastitis:

  1. Encourage breastfeeding (not from affected breast)
  2. Analgesia
  3. Antibiotics - Dicloxacillin or cephalexin (not needed in most cases)

Management of breast abscesses:

  1. US guided FNA
  2. Surgical incision and drainage
23
