Baby with cancer learns to walk three times

Video screengrab

A 23-month-old lad has already learnt to walk three times.

Just weeks after he took his first, tentative steps, cancer twice robbed him of his mobility.  

Reuben Clark has since undergone horrendous treatment. 

Despite so, he still smiles at the camera, as he plays and toddles around.

The cute toddler is from Darlington, County Durham. 

He was diagnosed with rare childhood neuroblastoma.

His condition is a cancer of the nerve cells that develops in the womb. 

He was diagnosed when he was just 16 months old.
