The family of an 11-year-old boy who suffers from a rare form of cancer are celebrating Christmas early in case he does not see the year out  Oliver Brown has Myelodysplastic Syndrome  – a blood cancer affecting four children per million worldwide –  and was told in May there were no further curative options available after two rounds of tortuous treatment  Now his family, from Plymouth, are bringing the celebrations forward with all the fixtures and treatment as it is his favourite time of year   Oliver’s dad Mike, aged 39 told Plymouth Live : “We have the lights up, the tree is up inside, we have the Lego winter village all made    “The only thing missing is a real Christmas tree but the place we always buy it from doesn’t start selling them until November 17 so we’re using a live tree at the moment and a fake one in the lounge – but everything else is up like it’s Christmas  “The Christmas movies are on, the Christmas songs are playing.  “I’m sure there’s been a few people driving past thinking “but it’s October” It is – but we’re having Christmas now.”    Mike said it’s accepted that it is unlikely Oliver will see Christmas  Oliver developed the rare disease aged eight as a result of a complicated genetic disorder relating to his GATA2 gene, which also resulted in Oliver being born deaf  For the last few months his parents, Mike and Nicky, along with his younger brother Benjamin, have been creating special memories and filling their days with happy activities – from days out with friends and family and occasional trips to school to see schoolmates to being made a cop thanks to Devon and Cornwall Police  The family would usually put up the decorations on December 1 and get “a good run”  Mike added: “We decided to bring it forward for him and Benjamin, to enjoy together In our minds he made it to Christmas 2019.  “He loves Christmas, so it’s the right thing for us all ”  In a poignant twist, Mike said it was clear the family should do the right thing and forget any traditional conventions following one incident earlier this year  He said: “Oliver put on the Arthur Christmas film in August or September and as I walked past him and Benjamin watching it I said it was bad luck to do Christmas when it wasn’t December  “Benjamin turned around and just said ‘we can’t get much more bad luck Dad’.  “He’s right and I just thought you guys crack on So it’s Christmas and we’re all going to enjoy it.”
