Abstract
The invention relates to a method for detecting cancer on skin of humans and mammals by picturing spectroscopy. The method includes that delta aminolevulimic acid ALA is applied on the skin on that area where cancer is suspected to be present, the substance is removed after 1 to 24 hours, and the area is illumiated with light having a wave-length of 330-440 nm and the fluorescent irradiation which arises is registered and evaluated, which radiation has a wave-length 610-715 nm. The invention also includes an arrangement for performing the method.
