Evan Wilson was born after just 15 minutes of labour, but midwives immediately spotted a swelling in his abdomen and took him from his mum Lorraine's arms for further examination.
Two hours later, he was diagnosed with liver cancer – making him the youngest Brit ever, and one of only a handful of babies to develop cancer in the womb.
Now six months old, Eva is awaiting the all-clear. Lorraine, 39, who lives with husband Scott, 41, in East Dunbartonshire, Scotland, said: "It was horrendous to go through as a mother.
None of the doctors knew what dose of chemo to give him because they had never had to treat anyone so young.
"We honestly thought he was going to die. I thought the doctors were going to tell us to enjoy Evan while we still had him.
"But when they came back and said they could help, I was overjoyed."
Lorraine's pregnancy had gone well and she gave birth to 6lb 9oz Evan at Glasgow's Princess Royal Hospital on November 18 last year
But the midwife spotted an abnormality in Evan's stomach and he was diagnosed with hepatoblastoma and underwent emergency surgery plus a gruelling six-month course of chemotherapy, enduring his first session at just 12 days old.
Lorraine said: "I only held Evan for a few minutes when they took him off me and all this began.
I was howling, I was completely irrational, I didn't know what to do. It sounds strange, but when they told us it was just liver cancer we jumped for joy because that meant it hadn't spread.
Lorraine and Scott, who also have six-year-old daughter Jorja, now have an anxious two-week wait for the results of Evan's MRI scan to see if he is in the clear.
Lorraine added: "Apart from a central gastric feeding tube in his nose he looks like a normal healthy boy.
"I can't praise the doctors enough, it is their skill and dedication that saved him especially with him being the youngest cancer patient in Britain."
