When Maddie Gillespie noticed a mark on her back after a night out, she assumed it was a cigarette burn - but after further investigations, she was dealt a devastating blow.
The 19-year-old was diagnosed with stage three cancer, only after the East Belfast woman's friend urged her to get the mark checked out by a doctor.
Speaking to Belfast Live, Maddie, who works in Lisnasharragh Leisure Centre as a receptionist, lifeguard and swimming teacher, underwent treatment for melanoma, a form of skin cancer. Now, she is raising awareness for the signs and symptoms of cancer in young people after going through her own doubts about her health.
