Does IPL camouflage skin cancer?

In the user manual for the Philips Lumea IPL hair removal device it states: Never use the appliance on the following areas: "On moles, freckles, large veins, darker pigmented areas, scars, skin anomalies without consulting your doctor. This can result in a burn and a change in skin colour, which makes it potentially harder to identify skin-related diseases (e.g. skin cancer)." How can this make it harder to identify skin cancer? Isn't IPL also used to remove freckles? Best regards, Tim
