Katie Rose Hayes from Florida is not even a year old, and she has already become a real sensation, The Daily Mail reported. 

According to source, the baby was born in September 2018.

Soon after birth, she was diagnosed with an aggressive form of a brain tumor - glioblastoma, that took up 60% of her brain. Doctors told their parents that if the girl survived the next night, they would have the surgery the very next day. As a result, surgeons managed to remove most of the tumor, which was similar in size to a tennis ball.

Next, the baby had to go through 10 stages of chemotherapy, and the last course was completed on May 31. Now Kathy is taking special drugs to prevent relapse.

According to doctors, the tumor was congenital, and was formed at the stage of intrauterine development.

Her mother, Mary, admits that at the beginning of this difficult journey, despite difficulties, she did not lose hope for the best.

“At beginning, it's very grim, but there's hope,” Mary said. “Yes, it's a bad thing to see a brand new baby go through this, but they're very resilient. As a mother, you develop a strength you didn't know you had.”
