Which type of keratinocyte cancer is the most common skin cancer?

2

Of the three main types of skin cancers, the deadliest are ( BCC - Basal Cell Carcinoma, SCC - Squamous Cell Carcinoma, Melanoma ) , which cause ~1,000 deaths in Australia annually. ( BCC - Basal Cell Carcinoma, SCC - Squamous Cell Carcinoma, Melanoma ) are also kinda not great, causing 340 deaths annually in Australia. ( BCC - Basal Cell Carcinoma, SCC - Squamous Cell Carcinoma, Melanoma ) are still not exactly fun, but "only" cause 60 deaths per year in Australia.

In regard to sunscreen, what does SPF stand for?

SPF is defined as:
( MED* of sunscreen-protected skin ) / ( MED* of unprotected skin )
What does MED stand for?
( Medical, Melanoma, Mesenchymal, Minimal ) ( Effective, Elevated, Epithelial, Erythemal ) ( Damage, Distance, Dose, Drug )

Imagine you are determining the SPF of a new sunscreen.
The MED of protected skin = 300 seconds
The MED of unprotected skin = 10 seconds
The resulting SPF rating would be?
