A
41
Q

A 55 year old post-menopausal lady presents to GP with a lump in her left breast. She has triple assessment and is told she has grade III invasive ductal carcinoma. She is also told she has ER8 PR8 HER2+. Is the ER8 PR8 HER2 a good or bad thing?

43
Q

2 - 1st lymph node cancer spreads and has to pass to move to different area
3 - lymph node metastasis are stopped at

A

2 - 1st lymph node cancer spreads and has to pass to move to different area

Axillary lymph nodes drains 85% of the lymphatic drainage from all quadrants of the breast

If sentinel has metastasis then distal lymph nodes need removing

47
