TRIBUTES are flowing in after Mandurah two-year-old Summer Coates passed away.
The brave toddler, affectionately known as Lion Heart, won over many people in the community with her fighting spirit.
Last year Summer was diagnosed with neuroblastoma stage 4 at just 11 months old.
She had five rounds of chemotherapy, two rounds of mega chemotherapy, surgery including the removal of a primary tumour in her abdomen, stem cell rescue and weeks of radiation.
While Summer was undergoing treatment, her grandparents Bev and Ross Brennan and mother Jess Coates, ineligible at the time for accommodation at Ronald MacDonald House, struggled to rent a unit in Perth to be close to Summer at Princess Margaret Hospital.
By March this year, she was in remission and when she turned two in June, her family celebrated with a birthday party.
But in August, her mother and grandmother found a small lump in her groin.
The following day it had doubled in size and they took her straight to PMH, where their world fell apart.
It was confirmed the cancer was back.
The community rallied behind the family, with fundraising and organising a birthday party in Furnissdale in September.
