Deborah James heartbreakingly spoke about how she could live longer as she opened up in a poignant interview on BBC Breakfast in May.
The podcast host, 40, died peacefully on Tuesday while surrounded by her family.
Last month, Deborah appeared in an interview as she shared her thoughts and final wishes.
She said that while she knew her children Hugo and Eloise would be fine, she broke down in tears as she said she was going to "miss every chance [she] could have had with them.
It came after Deborah announced that week that she was in hospice care and that she was spending time her last days surrounded by family and friends.
She was diagnosed with bowel cancer in 2016 and over the years has been heavily involved in charity work to raise money for cancer research and raise awareness through ITV's No Butts campaign.
Deborah raised more than £2million in just 48 hours - and has since gone on to raise more than £6.7million - as she asked people to "buy her a drink" to send her off by donating the money to Cancer Research UK.
She said: "I've always said I don't want to leave any stone unturned - I don't think there isn't a stone we haven't tried to unturn to make my liver work again in order to get my body functioning.
"Unfortunately I'm exhausted - I'm absolutely exhausted. We've got to the point now where I can't really do anything more. "
She continued as she began to break down in tears: "I have a really loving family who I adore. Honestly, they're incredible and all I knew I wanted was to come here and be able to relax knowing that everything was OK.
"I've had some really hard conversations during the last week. You think, 'Gosh, how can anyone have those conversations?' and then you find yourself in the middle of them. And people are very nice, but you're talking about your own death and I've had five years to prepare for my death."
Deborah went on to say that she didn't have a "grudge" or "angry that [she] hasn't tried everything".
"I don't feel like we've run out of drugs but we're still not - I'm still not there yet," she said as she began to get tearful.
As she struggled to speak, the interviewer said: "I know it's not easy."
"It's hard," she replied. "It's really hard. The thing that I know, because I trust my husband - he's just the most wonderful man and so is my family and I know that my kids are going to be more than looked after and surrounded by love.
"You always want to know as a mother - are your kids going to be OK? And my kids are going to be fine. But it doesn't mean I'm not going to miss every chance I could have had with them."
Addressing the money she had raised in just two days, Deborah said: "I always knew that there was one thing I wanted to do before I died. What I really want to happen is that I don't want any other Deborahs to have to go through this and I want - we know that if we catch cancer early we can cure it. We know that much more investment needs to take place for cancer.
"We know that we have the skills and the passion in the UK to do so. But I just feel that was still need that reminder and that boost and money.
"So before I died, one thing I knew I wanted to do was set up a fund that could continue working on some of the things that gave me life."
She added to viewers: "Please, please just enjoy life because it's so precious. All I want right now is more time and more life."
