A young woman was diagnosed with a 'one in a million' cancer at the age of 21 after finding a lump while on holiday. Perri Rowe first discovered a lump in her right breast which turned out to be rhabdomyosarcoma - a form of soft-tissue sarcoma which is extremely rare in breast cancer patients. The now 24-year-old was put on intensive chemotherapy before getting the all-clear, but is left with a 30cm scar across her chest after a mastectomy.
