Mel Swan-Horton, 46, thought she was getting into shape after dropping six dress sizes but was shocked when she learned she was suffering from terminal bowel cancer.
According to Daily Mail, Swan-Horton ignored the symptoms of the cancer and chalked up her rapid weight-loss to simply hitting the gym everyday.
After persistent bleeding which she attributed to lifting weights, she visited a doctor and was given her heartbreaking diagnosis.
Swan-Horton is currently receiving treatment for her disease but, as the cancer is terminal, it is only to keep her going day by day.
