19-year-old mom dies months after losing son, bravely delays cancer treatment for

A teenager who bravely delayed cancer treatment during her pregnancy only lost her newborn son a week after birth.

Brianna Rawlings made the headlines after her selfless act to give her son Kyden the best chance of survival while she was battling leukemia.

Tumble photos showed the 19-year-old girl holding her son after birth by an emergency cesarean, but lost her fight a few days later.

The teenager from Sydney, Australia, was only 17 weeks pregnant when she was diagnosed with the rare and aggressive form of blood cancer.

She had the choice to terminate her pregnancy or to bring her son to term by delaying treatment.

Her decision to continue her pregnancy effectively halved her chances of survival.

However, she was forced to give birth three months earlier as she began to suffer from excruciating pain and fevers.

Kyden tragically lost his fight for life 12 days later after contracting a stomach infection.

At that time, she told the Daily Mail: "I was able to spend these 12 days with my baby Kyden, holding him by the hand, counting his toes and fingers and talking to him as I would when he was in my belly.

"They were so special that they were the best 12 days of my life!

"Then the most shocking and heartbreaking news was that he had an infection in his stomach and in a few hours we were told to say goodbye.

"This infection took its precious life and our son developed his wings."

After facing the ordeal, Brianna's health seemed to improve, but she took a terrible turn for the worse.

After the medicine rejected a bone marrow transplant from his brother, his family began raising money for a drug trial that, he hoped, could save his life.

However, she tragically lost her life on December 29 after only two injections and a few days after her 19th birthday.

Confirming her death, sister Kourt Rawlings wrote on GoFundMe: "Our beautiful Brianna has reached the end of her journey with us here on earth and has finally been reunited with her baby bear Kyden.

"We are absolutely broken, but at the same time in peace, knowing that she has no more pain, that she is in pieces and uncertain of the news to come.

"We love you more than the stars, beautiful girl, fly high and guide those who are not sure how to be on this earth without your contagious smile."

Brianna fought leukemia in NK – a rare and aggressive form of the disease.
