Why is Anastrozole used over tamoxifen in postmenopausal women?
Aromatase is the main enzyme for oestrogen in peripherally, this is the main source of oestrogen in postmenopausal women
43
What is a sentinel node biopsy?
Where the lymphatic drainage of the breast using a dye or radioactive marker indicates the first lymphatic node(s), and therefore which may have malignant cell.
44
If a sentinel biopsy shows malignant cells what is the next course of action for a person with an excised breast cancer?
Total node clearence
45
What are the side effects of tamoxifen
DVT Endometrial thickening Hot flushes and headaches

47
What to describe when describing a lump?
``` Shape Size Consistency Hardness Tethering ```
48
What are the red flags for breast cancer?
Eczema Nipple changes and discharge Dimpling and redness Discharge

50
Describe what a lump in the breast feels like?
``` Stony hard Irregular Fixed Nipple retraction Skin changes ```
51
What is the pathophysiology of Peau d'orange?

52
What differentials for redness on the breast?
Immunocompromised Diabetic Smokers Inflammatory breast cancer
53
What does fungating in relation to breast cancer?
The cancer breaking through the epidermis out of the skin. Can smell. Can cause discharge.
