Taylor Swift has made the wish of one young teenage fan, suffering from a rare form of cancer, come true.

The singer, who is presently touring, visited 13-year-old Victoria Marsh backstage before her show in Philadelphia this weekend.

Marsh, who has Downs Syndrome, is a huge Swift fan and was bought tickets to the concert by the local police force after she was diagnosed with osteosarcoma (a rare form of bone cancer that predominantly affects children and teenagers) earlier this year.

She was unable attend the ‘Bad Blood’ singer’s show to due to her chemotherapy treatment and sent her two sisters instead.

In response the Dover, Delaware Police Force mounted an online campaign in May under the hashtags ‘#TeamVictoria’ and ‘#SwiftAWish’, asking Swift to drop in and visit Marsh.

The video received a massive response, swiftly going viral, with over one and a half million people viewing the short clip telling Marsh’s story.

On the night of the concert, doctors cleared the teenager to leave Nemours/Alfred I. duPont Hospital for Children for eight hours – allowing her to meet Swift backstage.

Although Marsh, who had her lower left leg amputated in February, couldn’t stay to enjoy the show her mother Karen Marsh told Delaware online that she had a “huge smile on her face”.

"It meant the world to her," she added.
