What is the A to E for skin cancer exam?
Asymmetrical
Border (irregular)
Colour (>2)
Diameter (>1/4 inch)
Evolving
Melanoma
Dx, mx
- most serious cancer
- commonly metastasise
- changes in A to E
- Breslow thickness to determine prognosis
- refer under 2ww pathway
- treat with surgical excision
SCC
Sx, rf, mx
- painless, firm, hyperkeratotic nodule
- ulcerated with thickened base
- rapid progression over weeks
- rf: sun exposure, skin types 1 and 2, immunosuppression
- refer via 2ww pathway
- mx with excision
BCC
Sx, mx
- most common
- slow
- pearly nodule with rolled edge, telangiectasia, central erosion
- rarely metastasise
- mx with excision but no urgency
