A MOTHER whose superhero six-year-old beat cancer says he has been “grinning” from ear-to-ear since he found out.

Frankie Clements, of Corfield Close, Barnet, spent 18 months undergoing treatment to destroy two tumours in his tummy.

But on Thursday, Frankie was told his dream of flushing the cancer – referred to as caterpillars – down the toilet had become a reality and he is finally in remission.

His mother, Caroline Kelly, said: “His dad, Chris, took him to hospital and when they got home he came running in to me and said – mum – guess what – I flushed the caterpillars down the toilet.

“His mood was ecstatic – he had a big grin on his face which hasn’t left. His dad burst into tears, he spent a lot of nights in hospital with Frankie. I cried too.

“It’s such a relief to know this nightmare is finally over.”

He was diagnosed in October 2014 and was given the all clear, and was then given treatment to stop it from returning and put him into remission.

Frankie, who hopes to grow up to be like Spiderman, has now been told the cancer is unlikely to return but will need to have regular check-ups.

Doctors fear his cancer could be being genetic so Ms Kelly’s other children, five boys and one girl, now need to be tested.

Meanwhile, Frankie, who was home-schooled during his treatment is due to go back to Danegrove Primary School but is dubious after such a long break.

He is due to go on a celebratory holiday to Norfolk with his family in July and is looking forward to touring the Arsenal stadium on Thursday.

Ms Kelly, 48, added: “It’s so nice to know that there is light at the end of the tunnel. I want to tell other people going through what we did to have faith.

“What we went through is horrible. I just thank my lucky stars that Frankie is okay now.”
