Q

What happens to the the mass in galactoceles?

A
  • duct gradually becomes more distended with milk and epithelial cells
  • may rarely be complicated with a secondary infection causing abscess formation
  • similar to cyst on examination

A

7-13% of young women have fibroadenoma at some stage during teens or twenties

45
Q

What actions must a GP make with someone presenting with a breast lump?

A
  1. All women with palpable breast lump should be referred to a surgical breast clinic even if you are fairly certain lump is benign
  2. Reassure patient
46
Q

How are solid lumps investigated in breast clinic?

A

triple assessment

47
Q

What makes up triple assessment?

A
  1. Clinical examination
