Zac returns to US for vital tests
Zac Oliver has returned to the US for the next stage of vital tests to see if he remains cancer free.
The Broseley five-year-old's mother, Hannah Oliver-Willets, has updated people on her son's situation, saying he will undergo a number of tests, all of which they need to return negative results.
The tests will be carried out at the Children's Hospital of Philadelphia, where Zac first underwent his revolutionary CAR-T therapy.
It was carried out after an incredible public fundraising campaign came up with the £500,000 needed to pay for the treatment, which is unavailable on the NHS.
The first stage of Zac's treatment was a success, with tests revealing that his body was cancer free.
The next stage will check to see if the CAR-T cells in his body are still working to keep him free of Acute Lymphoblastic Leukaemia.
In a post on the Facebook page set up to update people on Zac, Hannah said: "I can't believe how fast the last six weeks have gone since we got back from the Philadelphia."
While at the hospital he will have a bone marrow biopsy, three bone marrow aspirations, a lumbar puncture, and a blood test.
Hannah added: "We should get the results back for these tests at different times. One is within a couple of days, one will be after a week and the other takes two weeks. Nervous times ahead to say the least. In fact I'm not going to lie, this is terrifying. The fear of cancer spreading never gets easier."
Hannah added that they had already planned what to do after Zac has recovered from the tests.
She said: "Zaccy's chosen treat for a few days after his procedure once he has recovered, is to go to the aquarium to see the swimming hippos and sting rays. Sounds like a good choice to me."
