Brave Merryn brings a smile to Keano's face

Four-year-old Merryn Lacey suffers from neuroblastoma, an aggressive cancer of the nervous system.

Since her diagnosis last August, her parents have been fundraising to pay for her treatment at the children's hospital in Crumlin.

The brave little girl has just finished her 12th round of chemotherapy and may need to travel to the US for a special blocker treatment to prevent a relapse.

The treatment alone is expected to cost more than €100,000.

As such, Merryn's family are looking for all the help they can get and have enlisted the assistance of various Irish celebrities such as Roy Keane, Katie Taylor and Colin Farrell.

Her family has set up the Merryn Lacy Foundation and said that every penny will go towards her treatment and children's cancer research.

You can find out more about Merryn's fight and how you can help on her website Merrynlacy.com or on facebook.com/merrynlacy
