Ashley Cain has released a heartbreaking update about his 7-month-old daughter Azaylia Diamond’s health a month after announcing that her leukemia had returned.

On Thursday, in an emotional Instagram video, the 30-year-old revealed the devastating news that doctors have found cancerous tumors throughout his baby girl’s body, according to PEOPLE.

Cain said his daughter’s current chemotherapy “is not working,” adding that his plan to take her to Singapore for CAR T-cell therapy is no longer feasible given the discovery of the large tumors.

He said, “Last week, we had the bone marrow test and the lumbar puncture and bloods taken to send to Singapore in the hope that they could create a CAR-T therapy to save Azaylia’s life. Then, we had to have a CT scan on her head and the results came back the next day, saying that Azaylia’s got two very big tumors … on her brain.”

“The intrathecal treatment that is usually given to treat leukemia in the spine or the brain will not be available” due to “too much pressure” in her head, he added.

“If they tried to even go through the spinal tap it would kill her,” Cain continued, adding that doctors told him at the time that “they think she’s only got one, two days to live — and it could even be that night.”

Doctors initially spoke to Cain about “potential options of radiotherapy to target the tumors in her head,” but another CT scan showed tumors in Azaylia’s other organs, making further treatment difficult.

Tearfully, Cain said, “And the chemotherapy is not working. Her disease is that aggressive that nothing they are doing … is working. She’s one in a trillion, but unfortunately so is her disease.”

He explained that doctors in Singapore “can’t create a CAR-T for her leukemia” given the circumstances. “So, that means we’re going back home. We’re going back home and we’re gonna try and make our baby as comfortable as possible. We’re gonna be strong, and we’re gonna go out with honor.”

“She’s had a tough, tough life,” Cain continued. “From eight weeks old she’d been in hospital having chemotherapy, operations, transplants. And I feel like, for the last part of her life, I just want to take her home, see her like a baby and give her the best rest of her life that we can give her.” Cain first shared news of Azaylia’s leukemia diagnosis in October, according to PEOPLE, revealing that she has “a very rare and aggressive form of cancer.”
