Examination
Investigations
Breast conditions
– Benign / Malignant
• Treatment
History
• Presenting complaint is v important
• Lump;
– always ask how long been present
– Relation to menstrual cycle
– Does its size vary? Is it getting larger?
• Pain;
– Is it cyclical? Is the lump painful?
• Nipple discharge; ascertain
– Colour, Quantity, pattern, frequency
• Age of patient; cancers are uncommon
<30yrs, but fibroadenomas are
• Ask if noticed any;
– Nipple retraction
– Breast distortion
– Metastatic related symptoms
• Previous breast disease
– Was it investigated / treated
• Family history
– Genetics; 5-10% are inherited dominantly
• They have early onset & associated with other tumours e.g.
Bowel, ovarian.
• BRCA1 (chromosome 17q21)
• BRCA2 (chromosome 13q24)
• P53 gene chromosome 17
• Medications; HRT, pill
• Gynae / Obstetric Hx;
– Menarche, menses
– Parity? When? After 30 increases risk
– Breast fed?
Examination

•
Introduce yourself to patient
Undress to waist, sit on couch at 45 degrees
Maintain patient dignity e.g. Bed sheet
Assess in following positions
– Patient’s hands behind their head (accentuate lumps,
asymmetry, tethering)
– Pushing against their hips (accentuate lumps attached
to pectoralis muscle)
– Patient leaning over side of bed (accentuate
abnormalities in large breasts)
• Exam good breast first, then the ‘diseased’ breast
• Inspection
– 6 S’s

•
Site
Size
Shape
Symmetry
overlying Skin
associated Scars
• Fungation; comment on presence of fungating
carcinoma (check inframammory fold)
• Asymmetry; carcinoma may be present in higher breast
• Tethering; due to infiltration of ligaments of AstleyCooper
• Peau d’orange; micro-oedema
• Lymphoedema; may indicate lymphatic infiltration by
carcinoma or previous surgery with LN removal
• Erythema
• Nipple signs; 6 D’s
Paget’s Disease
Depression Deviation
Discharge
Displacement
Destruction
• Palpation
– Ask about pain and if patient has a lump.
– Examine good breast first then diseased breast
– Patient puts hand behind head on exam side
– Check for temperature change
– Use following with lumps;
•
•
•
•
•
•
•
•
Surface
Edge
Consistency (hard, firm, soft)
Fixity to skin and underlying structures
Fluctuance
Pulsatility and expansility
Transilluminability
Reducibility
• Palpate using palmar surfaces of index, middle
& ring fingers of both hands, sweeping down
clock face positions.
– N.B. Most carcinomas present in upper, outer
quadrant
• Remember;
– Inframammary fold
– Axillary tail of Spence
– Nipple discharge (explain important to check for
discharge, gain permission, gain permission)
• Axillary lymphadenopathy
– Support their arm with your corresponding arm
e.g. Patients right arm with you right arm and
palpate with your left hand
– Examine anterior, posterior, medial and lateral
walls in addition to the apex
•
•
•
•
•
Medial wall (seratus anterior)
Lateral wall (body of humerus)
Anterior wall (pectoralis major)
Posterior wall (latisimus dorsi)
Apices (arch of armpit – high in the head of the
humerus)
• Cervical and supraclavicular lymphadenopathy
• Always cover the patient when examination complete
and thank the patient.
• For completion;
• Respiratory exam; ?mets
• Abdomen exam; palpate liver (if hepatomegaly think
mets)
• Spinal exam; tenderness ? Mets
• Encourage self exam; encourage patient to regularly
monitor their breasts using simple examination infront
of a mirror
• Triple Assessment; If lump detected continue to this
Triple Assessment
1. Clinical Examination
2. Imaging; Mammogram (false negative rate
10% / USS (in <40yr)
3. Tissue Sampling;
-
FNAC (cytology exam of aspirate, can have 95%
sensitivity)
Core Biopsy
- Open Biopsy
Breast Disease
• Classify as benign or malignant
– Benign aetiology classified as Aberrations of
normal development and involution (ANDI)
Peak Age (years)
15-25
Development
Fibroadenoma & excessive Breast
development
25-40
Cyclical Hormonal
Cyclical nodularity & mastalgia
35-55
Involution
Lobular:
Ductal:
Epithelial:
Cyst
Duct ectasia & periductal mastitis
Hyperplasia & fibrosis
• What is a fibroadenoma?
– Most common benign neoplasm. Fibroepithelial
tumour, composed of glandular tissue & stroma.
– Peak onset 15-25yrs.
– Painless, smooth, firm, rubbery lump, highly mobile.
– Approx 10% resolve spontaneously within 1yr
• What are breast cysts?
–
–
–
–
Fluid-filled, distended & involuted lobules.
Present as smooth lumps. Maybe painful
Peak age onset 35-55yr.
FNA may relieve symptoms and can be analysed
• What are cyclical nodularity & mastalgia?
– Affect pre-menopausal females & are hormonal
dependent.
– Cyclical breast changes occur, result lumps
(nodularity) & pain (mastalgia) related to
menstrual cycle.
– Treatment options classified as;
Conservative
Medical
Surgical
Reassurance
Evening primrose oil
Firm supporting bra
Analgesia
Evening primrose oil
OCP
Mastectomy (for
treatment resistant
severe mastalgia)
Danazol
Bromocriptin
Tamoxifen
• What is duct ectasia?
– Involution & dilatation of subareolar ducts
– Clinical features; nipple inversion, nipple discharge
(may be cheese / blood stained), subareolar mass,
mastalgia.
• What is periductal mastitis?
– Inflammation, often due to infection of subareolar
ducts.
– May present like duct ectasia
– Pus discharge from nipple & mastalgia
• What is epithelial hyperplasia?
– Increase no. of epithelial lining cells of the
terminal lobular unit.
– Atypical dyplasia increased risk of progression to
carcinoma.
• What is fat necrosis?
– Often after trauma to fatty breast tisssue e.g.
Surgery / breastfeeding.
– Inflammation, fibrosis & calcification may occur
– Can be similar to carcinoma
– Most cases resolve spontaneouly
• Classification of breast tumours
Benign
Pre-Malignant / in situ
Malignant / Invasive
Fibroadenoma
Ductal carcinoma in situ
Invasive Ductal Carcinoma
(80% of invasive)
Intraductal Papilloma
Lobular carcinoma in situ
Invasive Lobular Carcinoma
(10% invasive)
Lipoma
Invasive Medullary,
Mucinous, Tubular &
Papillary Carcinomas (10%
invasive)
Breast Cancer
• Incidence 1:11
• Age; rare <30yr
• Risk factors;
–
–
–
–
–
–
–
–
Early menarche, late menopause
1st child >30yr
FHx in 1st degree relative
Hx of breast feeding
Prev breat ca
Radiation exposure
Exogenous hormones
High intake of saturated fats, alcohol
• Staging of cancer
– Bloods; FBC, LFTs, U&Es, ALP, Ca2+, ESR
– CXR
– 2nd line investigation; Liver USS, bone scan, CT-scan, axillary
node staging
– Clinical staging – TMN

N1 Ipsilateral mobile nodes
N2 Ipsilateral fixed nodes
N3 Internal mammary nodes
• M0 no mets
• M1 Mets in liver, lung, bone
Treatment
• Surgical;
– WLE plus DXT (need 1cm excision margin)
– Mastectomy
– Axillary sampling (removal of lower axillary nodes)
– Axillary clearance (removal of contents below the
level of the axillary vein)
• Level 1 = below pec minor
• Level 2 = behind pec minor
• Level 3 = above pec minor (full clearance)
– SLNB
• Systemic treatment
– Can be adjuvant or neo-adjuvant
1. Radiotherapy
-
Breast and chest wall
Axilla
Palliation (e.g. For bony tenderness)
2. Chemotherapy
-
Recurrent disease
<70yr with > 1 +ive axillary node
Very large tumours
• 3. Endocrine therapy and Tamoxifen
– Tamoxifen in ER + ive females
– Up to 15% of ER –ive females also respond
– Beneficial in pre- and postmenopausal women,
not effective in ER –ive premenopausals
– Increased risk of endometrial carcinoma
– Aromatase enzyme inhibitor = Anastrazole
(Arimidex)
• For post-menopausal women ER +ive
