Lynda Bellingham's heartbroken husband said he wanted people to remember his wife for her acting rather than "as a celebrity".
The star, best known for her long-running role as the mother in the Oxo TV adverts, had colon cancer which later spread to her lungs and liver.
She decided to end her treatment on August 13 to limit the amount of suffering her family would witness and had said she wanted one more Christmas at home with her family.
But Michael Pattemore said the advanced state of her illness meant it was clear she would have been unable to die at home as she dearly wished.
He told Yours magazine, for which his late wife was a columnist: "She was in too much pain and they didn't have it under control enough for me to be able to look after her."
Mr Pattemore added: "I just want her to be remembered as an actress more than anything - not as a celebrity or one of the Loose Women.
"She started her career as an actress and never thought of herself as a celebrity. She's always been an actress."
Lynda Bellingham's decision to end the chemotherapy would have given her a "sense of empowerment", the chief executive of the UK charity Beating Bowel Cancer has said.
Bellingham, who announced she was suffering from the disease last year, had said she had wanted to give up the harsh treatment to limit the amount of suffering her family would have to witness.
In her autobiography, due to be published later this month, she speaks of how she hoped it would mean she could spend one last Christmas with her family and then "pass away by the end of January".
Mark Flannagan, CEO of Beating Bowel Cancer, said it was impossible to say whether it was unusual for a patient to die so soon after giving up the treatment.
"I've known people who have been alive many years after a stage four [advanced cancer] diagnosis. It's very much down to the individual and that's why patients are given so much personalised care."
