Breast Flashcards
Breast hx associated sx
Relationship to LMP + sx Pain Nipple - discharge: amount, colour, consistency - bleeding - inversion Skin changes FLAWS Back pain/ breathlessness Any other lumps/gland swelling
Breast hx RFs
FHx of breast/ovarian cancer PMHx of breast disease/malignancy DHx; OCP, HRT Age of menarche + menopause; date of LMP Previous pregnancies; number, age of 1st one, breastfeeding
What to assess when examining a breast lump?
S he C uts T he F ish
S => site, size, skin, single
C => colour, contour, consistency, compressibility
T => tenderness, temperature, transilluminable
F => fluctuance, fixity (tethering), free to move
Fibroadenoma summary card
Benign neoplasm of a lobule from stroma and globular epithelium
= single, well demarcated, firm consistency, smooth, often painless, mobile lump
= breast ‘mouse’ of young women of child-bearing age
= USS/mammography
= observe, surgical excision lumpectomy or cryoblation if needed
Breast cysts summary card
Fluid filled sacs in breast
= simple/multiple, unilateral/bilateral, well demarcated, clear nipple discharge sometimes, painless mainly, transilluminable, fluctuant, mobile
= occurs in peri-menopausal women (40-50s)
= USS/mammography + FNA
= observe, FNA to drain fluid if needed
Duct ectasia summary card
Dilation of milk ducts due to blockage/non-lactational mastitis
= sub-areolar mass, nipple inversion, form consistency, thick and yellow/green nipple discharge, tender, fixed
= occurs in smokers, peri-post menopausal women
= USS/mammography
= Reassure and discharge, surgical incision if needed
Fat necrosis summary card
Occurs at any age secondary to traume
= painful, irregular hard lump with overlying bruising/redness of skin
Intraductal papilloma summary card
Benign neoplasm growing within ducts of breast
= small subareolar mass with bloody/clear nipple discharge
= peri/post menopausal women
Mastitis summary card
Inflammation of breast due to milk-stasis/overproduction
= generalised swelling of skin, inflamed skin, cracked nipple, redness and firm, very tender and uncomfortable to touch, flu-like sx
= Staphylococcus aureus most common pathogen
= Mx: encourage breast-feeding, analgesia, Abx if required
What can mastitis lead to?
Abscess
= Ix + mx: surgical incision and drainage, FBC, blood cultures, US guided FNA, IV/oral Abx
= complications: mammary fistula, rarely overlying skin may undergo necrosis
Sx + signs of breast cancer
S
= increased size, lump, skin changes (dimpling, discharge, peu d’orange)
C
= hard lumps, irregular, redness, non-compressible
T
= generally painless, inflammatory breast
F
= tethered to underlying tissue, not free to move
Mets
= bone pain, breathlessness, neuro sx (rare)
Ix for breast cancer
- Triple assessment
1. clinical examination
2. imaging (<35: USS, >35 mammogram)
3. tissue diagnosis (FNA, core biopsy)
Bloods
- ESR, bone profile, LFTs, Ca2+, U&Es, FBC
Staging
- CXR, liver USS, CT brain/chest, bone scan
- mets to liver, bone, lungs common
Types of breast cancer
Non-invasive
- ductal carcinoma in situ
Invasive
- infiltrative ductal carcinoma (most common)
- infiltrative lobular carcinoma
- Paget’s disease of the breast
Mx of breast cancer
Radiotherapy
- reduce recurrence post-surgery
Monoclonal antibodies
Chemo
- neo-adjuvant/adjuvant
Meds
- ER antagonists (tamoxifen)
- aromatase inhibitors (letrozole)
Surgery
- total masectomy
- lumpectomy
- sentinel LN biopsy/axillary LN clearance
*treatment based on type, staging and grade of tumour
Neck lump ddx
Infection - lymphadenopathy, fever, fatigue = glandular fever, HIV Malignancy - lymphadenopathy, FLAWS, growing lump = thyroid cancer, salivary gland cancer Endocrine - goitre = hyper/hypothyroidism Derm = sebaceous cyst; blocked hair follicle = lipoma; benign tumour of fat tissue Vascular = carotid body aneurysm Congenital/developmental = bronchial cyst = thyroglossal cyst; persistent duct-embryonic structure
Midline lump ddx
Moves on tongue protrusion = thyroglossal cyst Moves on swallowing = thyroid gland Superficial = lipoma, epidermal cyst, dermoid cyst, abcess Deep = thyroid
Anatomy of anterior and posterior neck triangles
Anterior
= SCM, midline of neck, mandible
Posterior
= SCM, trapezius, clavicle
A 36-year-old woman presents to the urgent care centre with a small
tender mass under her left nipple. The area is tender to touch and she’d
noticed a small amount of yellow-green discharge from the nipple. She
mentions to you that she’s smoked since her early 20s.
What is the most likely diagnosis?
A – Breast cyst B – Lobular carcinoma C – Non-lactational mastitis D – Duct ectasia E – Breast abscess
D – Duct ectasia
A 22-year-old woman presents to the GP with a lump in her right breast.
She found the lump incidentally and has not experienced any symptoms.
On examination, the lump is located in the upper outer quadrant and is 2cm.
It feels firm, smooth and well demarcated and is mobile.
What is the most likely diagnosis?
A – Phyllodes tumour B – Fibroadenoma C – Breast cyst D – Ductal carcinoma in situ E – Mastitis
B – Fibroadenoma
A 32-year-old woman comes to the GP complaining of a painful left
breast. She gave birth a few weeks ago and has been breast-feeding every
few hours. On examination, the breast is tender, there is marked erythema
and her nipple is cracked. You do not suspect there are any abscesses
present.
Given the likely diagnosis, which of the following is NOT a recommended
treatment option?
A – Stopping breast feeding B – Antibiotics if symptoms are severe C – Analgesia D – Anti-fungals if nipple candidiasis suspected E – FNA to rule out an abscess
A – Stopping breast feeding
A 55-year-old is referred for an urgent mammogram after noticing a lump
in her right breast.
Which of these is NOT a recognised risk factor for breast cancer?
A – Increased age B – Use of the combined oral contraceptive pill C – Obesity D – Having more than 1 child E – Family history of ovarian cancer
D – Having more than 1 child
A 60-year-old woman presents to the GP after noticing some changes in
her right nipple. On examination, the nipple is erythematous and crusty with
some apparent scaliness of the skin.
What is the most likely diagnosis?
A – Eczema B – Paget’s disease of the breast C – Intraductal papilloma D – Ductal carcinoma E – Phyllodes tumour
B – Paget’s disease of the breast
A 56-year-old lady presents to the GP with a lump on her neck. She doesn’t
report any other symptoms, apart from being a bit more anxious and tired

move when the patient sticks out her tongue however does move when she
swallows.

A – Thyroglossal cyst B – Goitre C – Thyroid nodule D – Lipoma E – Dermoid cyst
C – Thyroid nodule
A 60 year old obese woman presents to her GP with a
lesion on her breast. The lesion is red, crusted, around her
