Little Martin Alvarez Muelas has died after his heroic fight against brain cancer. He was diagnosed with a diffuse midline glioma with H3 QM27 mutation, a tumor with a survival rate of 1% and a median life expectancy of 12 months.

His brother Rafa, who shared the day to day of the little one on his Instagram account and who initiated several collections of signatures to ask for investment for research, has given the tragic news. But Rafa does not intend to throw in the towel and pointing to Health and the President of the Government in his publication affirms that "they do not want letters giving condolences"
