3. Introduction
 A fibroadenoma is a benign, or
noncancerous, breast tumor. Unlike a breast
cancer, which grows larger over time and
can spread to other organs, a fibroadenoma
remains in the breast tissue.
 Presently it is considered as a hyperplasia of
single lobule of the breast

4. Fibroadenoma
1. Commonly seen in young age group of 15-25 years
2. It is the most common benign tumour of the breast below 30 years of age in
female.
3. It is aberration in normal development of a lobule
4. It shows similar hormonal activities of normal breast like lactation and
perimenopausal involution
5. Incidence is 15% of palpable breast lumps
6. It is bilateral in 20% of the cases . 20% are multiple
7. Juvenile fibroadenoma occurs in adolescent girls
8. Complex fibroadenoma is a condition with fibrocystic changes like cyst
formation and apocrine metaplasia

5. Fibroadenoma
8. 30% of fibroadenoma disappear in size within 2-4 years
9. 10-15% will increase in size progressively . It doesn't occur after menopause unless
there is external hormone intake
10. Fibroadenoma does not turn into malignancy

6. TYPES – gross classification
soft
giant
hard

outline
• MRI if necessary

10. Treatment
Excision through a circumareolar ( webster’s) or
submammary incision (Gaillard Thomas incision) is done
under general anaesthesia

11. Treatment
 Fibroadenoma which is small < 3 cm / age <30 years can be
left alone with regular follow-up with USG at 6 month intervals
 However anxiousness of patients and parents makes this
conservative management difficult
