People who work outside all day for many years, like gardeners or road workers, are much more likely to get a type of skin cancer called SCC than people who work inside, because of all the sun...

People who work outside in the sun every day, especially sailors and gardeners, have a much higher chance of getting skin cancer than people who work indoors—even more than other outdoor jobs like paving roads.

Even among people doing the same outdoor job, some get way more sun than others—so some are much more likely to get skin cancer, depending on how they work and whether they use shade or sunscreen.

Spending lots of time in the sun on vacations or weekends is more likely to cause BCC than being outside during daily routines like walking to work.

The safety limit for sun exposure at work is too low—many outdoor workers in Lisbon get 3–4 times more sun in a day than the current safety rule allows.

Different kinds of skin cancer are caused by different kinds of sun exposure: melanoma by childhood sunburns, BCC by weekend sunbathing, and SCC by years of daily sun exposure.
