This document describes aberrations in normal breast development and involution. It discusses various benign and malignant conditions that can occur, including lumps, pain, nipple discharge, galactorrhea, and nipple changes. Potential causes are endocrine disturbances, genetic factors, environmental exposures, and developmental anomalies. Conditions range from near-normal to severe disease. Management depends on the condition but may include reassurance, lifestyle changes, medications, or surgery. Differentiating benign from malignant conditions requires evaluation using a triple assessment approach.
2. Developed and described by Cardiff
breast clinic in Wales
Wide spectrum of clinicopathological
features ranging from near normality to
severe disease
3. Aetiopathogenesis – some theories
Endocrine factors
1. Disturbances in the Hypothalamo Pituitary Gonadal steroid axis
2. Altered Prolactin profile – qualitative /quantitative change
Non endocrine factors
1. Methyl xanthines, Stress
Genetic predisposition to catecholamine supersensitivity Intra cellular
C - AMP mediated events cellular proliferation
2. Diet rich in saturated fat
Altered plasma essential fatty acid profile receptor supersensitivity to normal
levels of Oestrogen & Progesterone
3. Iodine deficiency
Receptor supersensitivity to normal levels of Oestrogen & Progesterone

7. Developmental anomalies
Athelia-absence of nipple
Amazia-absence of breast tissue.asso with
poland syndrome
POLYMASTIA-common
Commonly in axilla
Supernumerary nipples-male
predominance 1.7:1
Assn. With other syndrome-
turner,fanconi,ectodermal dysplasia
8. DIFFUSE HYPERTROPHY
Occurs in otherwise
healthy girls
at puberty
Alteration in the
normal sensitivity
of the breast to
estrogen
Reduction
mammoplasty
9. 1. Lump
Discrete lump
Fibroadenoma
Giant fibroadenoma
Juvenile fibroadenoma
Phyllodes tumours
Cysts : macrocysts
Nodularity
Generalised
Localised
Age incidence of lumps in the breast
10. Fibroadenoma
Types Natural history
Solitary
Few (< 5 / breast ) Majority remain small & static
Multiple (> 5 / breast ) 50% involute spontaneously
Giant (> 4 / 5 cms) & Juvenile No future risk of malignancy
11. Phyllodes tumours
Comprise less than 1% of all breast neoplasms
May occur at any age but usually in 5th decade of life
No clinical or histological features to predict recurrence
16 - 30% may be malignant
Common sites of metastasis : lungs, skeleton, heart, and liver
12. Treatment of Phyllodes tumours
1. Primary treatment
Local excision with
a rim of normal tissue
2. Recurrence
Re excision
or
Mastectomy with or
without reconstruction
Response to
chemotherapy and
radiotherapy for
recurrences and
metastases poor
13. Cysts
Common in the West ( 70 % of women )
50% are solitary cysts
30% 2 - 5 cysts &
rest have > 5 cysts
Types
Apocrine cysts
Lined by secretory epithelium
Cyst fluid has a Na : K ratio < 3
Likely to have multiple cysts
Likely to develop further cysts
Non apocrine cysts
Cyst fluid has a Na : K ratio >3
Resembles plasma
Mixture of both

15. 2. Pain
Mastalgia
• Cyclical mastalgia
• Non cyclical mastalgia
•True (breast related)
• Musculoskeletal : costochondral or lateral chest wall
Infections
True breast pain
• Lactational infections
• Nonlactational infections
• Central : Periductal mastitis (inflammation, mass, abscess, mammary duct fistula)
• Peripheral : associated with diabetes, rhuematoid arthritis, steroid usage, trauma etc.
• Rare : Tuberculosis, Granulomatous mastitis, Diabetic (lymphocytic) mastitis, etc.
• Skin associated : intertrigo, infected sebaceous cyst, hidradenitis suppurativa etc.
16. Mastalgia
Definition : Pain severe enough to interfere with daily life or lasting
over 2weeks of menstrual cycle
True breast pain breast pain
True
Lateral chest Costo
wall pain Chondral pain
mild
Musculo skeletal pain
17. Management protocol for true mastalgia
• Assess type of pain
• Assess severity of pain ( Pain diary + Visual analogue scale )
• Evaluation with Triple assessment
• Treatment :
Reassurance is the key to management
Use of supportive undergarments
Low fat, Methyl xanthine restricted diet
Stop Oral contraceptives / HRT etc
Review patient. Sucessful in the majority ( 80 – 85 % ) of patients
Start drugs in those not responding to nonpharmacological treatment
Review and assess response
18. Drugs of established value in mastalgia

Management :
Estimate PRL levels. If very high, evaluate for pituitary lesion
Physiological - Reassurance, cessation of stimulation
Drug induced - Stop or change drug if possible
Pathological - Cabergoline / Bromocriptine, treat cause if possible ( E.G.
Pituitary surgery)
