BREAST CANCER: EARLY DIAGNOSIS BETTER PROGNOSIS DR. A. AKHATOR FWACS, FICS SENIOR LECTURER DELSU CONSULTANT SURGEON DELSUTH
PRE-TEST • Breast cancer is the most common cancer in women in Nigeria • Breast cancer is the most common cause of cancer related deaths • Breast cancer commonly present as painful breast lump • Prognosis of breast cancer is related to the size of the breast tumor • Trastuzumab (HerceptinR) is treatment for ER/PR positive tumor
LEARNING OBJECTIVES • Realize the burden of breast cancer in our environment • The importance of early diagnosis in management of breast cancer • Evaluate breast cancer symptoms and recommend appropriate management
INTRODUCTION • Breast cancer – malignant neoplasm arising in the breast. • Most common cancer in women worldwide. • Incidence in Nigeria is 33/100,000 • Incidence in males 1-9% of cases • Peak age 42 years • 78% locally advanced disease • 22% metastatic disease
THE FACTS ABOUT BREAST CANCER • APPROXIMATELY EVERY 3 MINUTES A WOMAN IS DIAGNOSED WITH BREAST CANCER • APPROXIMATELY EVERY 12 MINUTES A WOMAN DIES FROM BREAST CANCER • INCIDENCE INCREASING 5%/YEAR IN DEVELOPING COUNTRIES • A REVIEW 1991 – 33% ADVANCED DISEASE IN DEVELOPED COUNTRIES • 2007 – 60-80% ADVANCED DISEASE IN DEVELOPING COUNTRIES
MORE FACTS • IN THE UK 2009 • NEW CASES - 38,212 FEMALES, 250 MALES • SECOND COMMONEST CANCER DEATHS • IN US • 211, 240 NEW CASES EXPECTED IN WOMEN • 1,690 NEW CASES IN MEN • African-American women have a lower incidence but higher mortality • They also have higher risk for triple-negative tumours • INCIDENCE – 128.6/100,000 POPULATION • Life time risk of 1 in 8 women
Factors that increase risk • Family History • Lifestyle • Personal History
Family History • Mother, sister, or daughter has developed breast cancer before menopause 3 x. • If two or more close relatives (e.g., cousins, aunts, grandmothers) have/had breast cancer. • Mutations in genes BRCA1 and BRCA2 increase one's susceptibility to breast cancer.
FAMILY HISTORY • SHARED GENETIC MAKEUP • SHARED LIFESTYLE • SIMILAR ENVIRONMENTAL EXPOSURE • 5-10% CAUSED BY INHERITED GENETICS
PERSONAL HISTORY • Previous history of breast cancer • Previous history of benign breast disease • Menarche <12 years • Hormonal contraceptives – current and recent users • Nullipara • First delivery after 30 years • Menopause at 55 years or older • Hormonal Replacement Therapy
Lifestyle • Several studies found a lower incidence of breast cancer among women who exercise regularly • Higher proportion of breast cancer among obese women. • Smoking
OTHER LIFESTYLE FACTORS • ALCOHOL – one or more drinks a day increases risk • DIET – High in fruits and vegetables decreases risk • EXERCISE – Regular exercise decreases risk • WEIGHT – Maintaining healthy weight decreases risk
ENVIRONMENTAL RISK • POLYCYCLIC AROMATIC HYDROCARBONS – Chemicals produced when coal, oil, gas, garbage are burnt – increases risk • SMOKING – Passive smoking increases risk; when smoking started as teenager • ELECTROMAGNETIC FIELD – NO RISK
BREAST CANCER MYTHS • SHAMPOO – NOT TRUE • WEARING BRA – NOT TRUE • PUTTING MONEY IN BRA – NOT TRUE • RADIATION FROM CELL PHONES – NOT TRUE • ANTIPERSPERANTS/DEODORANTS – NOT TRUE • BREASTFEEDING GRANDCHILDREN – NOT TRUE • WITCHES INFLICT – NOT TRUE
CLASSIFICATION • Heterogeneous disease at each stage • Early breast cancer (Tis-2/N0-1) • In situ disease • Invasive • Late breast cancer (T3,4/N2/M1) • Locally advanced • Metastatic disease
STAGE GROUPING • STAGE 0 – Tis, N0,M0 • STAGE IA – T1, N0,M0 • STAGE 1B – T0 or T1, N1mi, M0 • STAGE IIA – T0 or T1, N1, M0; T2,N0,M0 • STAGE IIB – T2, N1, M0; T3, N0, M0 • STAGE IIIA – T0 to T2, N2, M0; T3, N1 orN2,M0 • STAGE IIIB – T4,N0-N2,M0; • STAGE IIIC – any T, N3, M0 • STAGE IV – any T, any N, M1
EARLY DIAGNOSIS ….. • Early diagnosis leads to better prognosis • The size of the tumor and extend of spread determines the prognosis • Early stage • Better possibility for cure • Less morbidity • Less toxic treatment
PROGNOSIS • Overall survival/Disease free interval • Quality of life • Adverse effect/toxicity of treatment • Body habitus • Psychological
PROGNOSTIC FACTORS • Age • Tumor size • Axillary LN status • Histological grade • Receptor status – ER, PR • HER2-neu(C-erb B2)
OVERALL SURVIVAL • CURE RATES FOR BREAST CANCER • 5 year cure rates of >90% obtainable for early tumours, • < 30% for late tumours
SURVIVAL RATES BY STAGE • Stage 0 – 93% • Stage I – 88% • Stage IIA – 81% • Stage IIB – 74% • Stage IIIA – 67% • Stage IIIB – 41% • Stage IIIC – 49% • Stage IV – 15%
QUALITY OF LIFE • Scars of treatment/no breast • Younger survivors face • Emotional stresses • Trouble with social functioning • Chemotherapy induced early menopause • Sexual difficulties
DIAGNOSIS • ASYMPTOMATIC PATIENT • SCREENING • BSE • CBE • Mammography • MRI • SYMPTOMATIC PATIENT • Clinical evaluation • Diagnostic investigations
Breast Self Exam Be Safe, Be Sure
Advantages of BSE • It is simple and easy to perform. • It is convenient and requires little time. • It is private. • It involves no medical cost • It is safe and non-invasive. • It requires no specific equipment.
Methods of training • Pamphlets and leaflets. • Instructional videos. • Demonstrations and personal instructions.
Breast-self-examination • Breast self examination – monthly • Understand the breast and look for changes • Development of a lump. • Swelling. • Skin irritation or dimpling. • Nipple pain or retraction. • Redness or scaliness of the nipple or breast skin. • Discharge - other than milk. • Standing and lying
When to do a Breast Self-Exam The best time to do breast self-exam is right after her period, when breasts are not tender or swollen. If she does not have regular periods or sometimes skip a month, do it on the same day every month.
Clinical Breast Examination • BREAST EXAM BY DOCTOR (CBE) – EVERY 3 YRS BETWEEN 20-39YRS; • YEARLY AFTER 40YRS, before mammogram • POOR SENSITIVITY - 54% • HIGH SPECIFITY – 94% • CBE-detected tumourshas 70% survival
Mammogram • XRAY OF THE BREAST (MAMMOGRAM) – YEARLY AFTER 40 YRS • Mammography-detected tumours has 90% survival • Mammography increased detection of DCIS from 1% to 21% • Regular screening by mammography and CBE decrease mortality by 25 – 30% in women 50years or older
EARLY DIAGNOSIS • TRIPLE ASSESSMENT • CLINICAL EVALUATION • IMAGING • HISTOCYTOLOGY
CLINICAL EVALUATION • History • Progression of symptoms • Risk factors for breast cancer • Treatment to date • Physical examination • Local • systemic
FEATURES OF BREAST CANCER • Breast lumps – painless • Swelling of the breast • Nipple discharge – blood stained • Retraction of the nipple • Changes in the skin of the breast • Breast or nipple pain • Signs of spread
IMAGING • Breast scan • Mammogram • Digital mammogram • Computer aided diagnosis (CAD) • MRI • OTHERS • Thermography • Scintimammography • Tomosynthesis (3D Mammography)
HISTOCYTOLOGY • TYPES OF BIOPSY TECHNIQUE • FNAC • Core Needle • Vacuum assisted • Open biopsy • Incisional • excisional
