The Lions Club of Victor Harbor and Port Elliot are holding free skin cancer screenings at Victor Central Shopping Centre Carpark.
Appointments are available on Saturday, September 28, 9am to 3.45pm and Sunday, September 29, 9am to 3pm.
Lions Club board member Ruth Pearsons said the club was proud to host the important service.
"There's lots of people, especially when you get to the country, that don't check their health," Ms Pearsons said.
"A lot of people don't realise they need it."
Lions Club president Brian Yuill has received skin cancer treatments himself and encourages people to utilise the free service.
Factors that can increase the risk of skin cancer include, a family history of malignant melanoma or skin cancer, fair skin that burns rather than tans, blistering sunburn as a child, or previous mole removal.
Things to look for include, five or more moles (not freckles) on your forearms, moles or freckles that have changed size, colour or shape, and inflamed skin sores that do not heal.
Club member Chris Ramsey has seen the number of people the screenings help.
"The figures of the day are quite enormous," Ms Ramsey said.
"More than 20 per cent of people are consistently told to go and see a doctor immediately."
Bookings are essential, call 0408 904 574.
