Ed Sheeran and his wife, Cherry Seaborn, are getting candid about her cancer diagnosis.

In the Disney+ documentary, Ed Sheeran: The Sum of It All, the GRAMMY-winning singer breaks down the personal and intimate events in 2022 that inspired him to complete his album, Subtract

Throughout the limited docuseries, which is broken down into four parts, LoveLossFocus and Balance, Sheeran and Seaborn open up about her cancer diagnosis and the effects it has had on their relationship. 

In episode one, Seaborn - who has remained largely out of the spotlight, details the diagnosis. Seaborn reveals that the doctors found a tumour in her arm when she was six months pregnant.

During a date night at a painting studio, Seaborn shares why the diagnosis inspired her to take part in the documentary. 

"I got diagnosed with cancer at the start of the year which was a massive sh*tter," she says. "It made me massively reflect on our mortality. I would never agree to do anything like this, but it made me think, 'Oh if I died, what's people's perception of me? What do you leave behind?'"

Seaborn adds, "For Ed, the whole point is he wants to say to people, 'I'm not just this music machine. I'm not just this robot that tries to get No. 1. I'm a father, I'm a son, I'm a friend.' It wasn't until this year when I was like, 'I might die.'"

Sheeran gets serious and emotional in the moment as he tells his wife that she is downplaying the diagnosis. 

"It was horrible," the "Shape of You" singer says.

Further into the episode, Sheeran notes how he tried to convince himself that everything would be OK, but it wasn't.

"I kept saying to you that it was just a lump and not to worry," he tells his wife. "I remember rehearsing and getting a call from Cherry. The doctor was basically like, 'This is bad.'" 

The couple adds that after months of looking at treatment plans and finding out that Seaborn's diagnosis was "much less severe" than what they were initially told, Seaborn was able to have her baby and have a successful surgery shortly thereafter. 

Elsewhere in the documentary, Sheeran reflects on how traumatic events kept happening back to back -- from his wife's cancer diagnosis to the death of his best friend, Jamal Edwards, and the 3-week court case where he was accused of plagiarizing his hit, "Shape of You."

During the case -- which he won -- he could only focus on his wife.  

"I'm sat in this courtroom with people shouting at me from all different angles, and in my head I'm like, 'I hope Cherry's all right,'" he recalls. "'I could lose this court case and life goes on, but life doesn't really go on if the person you love the most isn't in it.'"

Sheeran reflects on the pain he felt during his wife's cancer diagnosis and how it inspired him to make more music. 

"The moment you find out that the worst thing in the world has happened to someone you love with all your heart, you feel like you're drowning and can't get out from under it. Just from that situation, all these songs came out," he says.

Seaborn -- who tied the knot with the singer in 2019 -- reveals that while her husband is working to cope with the events, she has not been able to have a conversation with him about his mental health. 

"We've barely had a conversation this year about his mental health," she says. "I can see it and it's massive alarm bells to me. I'm in a much better place from a processing perspective. I don't think Ed is there yet. There's no way he's had time to sit and process and be at peace with things. He's been too busy. He needs to stop, he needs to process. He hasn't processed at all."

In a full-circle moment during the final episode, Sheeran and Seaborn unwrap the paintings from their date night to hang in their home the day after she finds out that she had a clear MRI and the cancer did not return. 

"It all looks good, lymph nodes are all calmed down and everything," she says. "So that was amazing, it was massive of us actually." 

In the end, Sheeran admits that he was feeling much better going into the new year. 

"All great news and heading into a year, where it's hopefully all good news," he says as he hugs his wife. "I feel great, super pumped."
