The campaign features Scottish actress Elaine C Smith, who lost her mum to breast cancer, holding up a series of placards featuring pictures of women's breast, to illustrate the symptoms of the disease.
The TV ad by The Leith Agency spreads the message that "Lumps aren’t the only sign of breast cancer’, so that women will know how to spot the signs.
Guy Vickerstaff, head of art and Phil Evans, copywriter, from The Leith Agency were behind the spot, which was directed by Alex Telfer and produced by MTP.
Evans said: "The finished ad is stripped back and laid-bare. A straightforward but heartfelt appeal to every woman in Scotland."
The Detect Cancer Early campaign aims to increase the early detection of cancer by 25%, saving more than 300 lives a year by the end of the next Parliamentary term.
