Dr Maryam Tabatabaeian
Benign breast lesions
Non proliferative no risk for malignancy cysts,fcc without hyperplasia,epithalial calcifications,apocrine papillary changes, Proliferative without atypia 1/5-2 × risk Ductal hyperplasia,papilloma,sclerosing adenosis,radial scar,fibroadenoma Proliferative with atypia 3/7-5/3 × risk ADH,ALH
Fibroadenoma B3
Single or multiple(FH) Most masses in women<30yrs Size>3cm,age>35yrs,FH+,growth rate>30% in 3 months biposy or excision if patients is stressed Giant fibradenoma>5cm benign 17%regression without therapy Macrolobulation is normal microlobulation needs biopsy Complex fibradenoma surgery
Cysts
Simple cyst B2 thin wall,single or multiple,clear content,size<3cm no risk ,routine follow up Complicated cyst B3 thick wall<5mm,septation,internal echo,no flow in doppler sono 0/4% malignancy hematoma,absess,fat necrosis,galactocele Complex cyst B4 Thick wall>5mm,size>5cm,mass component,shadow absses,apocrine metaplasia,oil cyst,fat necrosis,malignancy 20-40% malignant
Mass
<30 yrs mostly benign 75%fibroadenoma >50 yrs half malignant <30yrs sonogram >35 yrs mammogram BIRADS 3 without riskfactor follow up BIRADS 4 or B3 with risk factor biopsy Biopsy CNB
Mass
Mammogram 20% false negative 40- 50 yrs 10% false negative>50 yrs After a negative biopsy follow up each 6 months to 2 yrs is mandatory
Thickening
2 dimentional lesion Mammogramm and sonogram and other complementary test as indicated 10-17% need biopsy 50% of biopsies are malignant no need to medical treatment
Papilloma
is benign but needs surgery because of nipple bleeding Papillomatosis malignancy : .5 papilloma in one segment no risk for
ADH,ALH
Gail model for risk assesment No OC or HRT Flat epithelial hyperplasia exscision, less risk for malignansy
hamartoma
Fibroadenolipoma malignant tranformation sugery
Adenoma
Pure epithelial component,tubular and lactating subtype No risk for malignancy Surgery in suspicious forms
Granulomatous mastitis
non TB granulomatosis Presents as mastitis or inflamation and mass Dx CNB Treatment :treatment of absses and then corticosteroids in refractore cases Surgery has malconvinient results and deformities cause to unnecessary mastectomies
