A PENSNETT GP is getting set to pound the streets in tomorrow's London Marathon - to help raise money for the hospital which has treated her son for a brain tumour.

Louise Butler, who works at High Oak Surgery in Pensnett and Kingswinford Medical Practice, will be taking part in the 26-mile road race in aid of Birmingham Children's Hospital.

The 38-year-old GP, who lives in Walsall, said she "cannot thank the hospital enough" for saving her son Joel's life.

The seven-year-old was diagnosed with a malignant brain tumour in January 2011, and has undergone three operations and 15 months of chemotherapy treatment.

But his most recent recent scans show he is now clear of cancer, Louise told the News.

She said: "I'm so proud of him for getting through this, he never complains and always has a cheeky smile. Cards and presents do not seem enough to thank the hospital so I decided to take part in the London Marathon - as I'm always after a challenge.

"Hopefully by finishing the marathon more money will be raised and the hospital's reputation will be advertised for all to see."

She said Joel and her daughter Eve, aged nine, will be venturing to London with her to watch the race, adding: "Seeing their faces will spur me on, especially little Joel's smile."

She said the kindness and generosity of her patients at Kingswinford and Pensnett would also help keep her going. She added: "They have been wonderful; very supportive - donating money and gifts to the hospital."
