RTE broadcaster Aine Lawlor has spoken of her 'heartbreak' following the death of a woman who featured in her recent documentary series.
Deirdre Donovan took part in the critically acclaimed and highly rated series 'Facing Cancer'.
Sadly, Ms Donovan passed away this morning.
"Heartbreak. Deirdre Donovan lost her fight with cancer this morning.#facingcancer," News At One broadcaster Aine wrote this morning.
Deirdre made a memorable appearance on 'Facing Cancer', making an impression of Aine and viewers alike.
The series looked at how Ireland is facing a cancer epidemic in the next 25 years and asked whether the pace of advancements in new treatments are coming fast enough for patients.
During the show, it stated that Deirdre's cancer had all but disappeared.
She found out she had cancer after going to the doctor to cure an itchy mole. She was later diagnosed with malignant melanoma, an aggressive skin cancer.
However, since recording the documentary series, the cancer returned.
During the series, Aine referred to her interviewee as "brave and brilliant Deirdre" and said she was grateful to her for taking part in the show.
The broadcaster did the series following her own battle with cancer.
She was diagnosed in September 2011 and famously told Morning Ireland listeners about her taking a break from the show to undergo treatment.
After undergoing treatment and a mastectomy, Aine (52) was given the all-clear in April 2012.
The programme also saw Lawlor explore the developments in breast cancer treatment since the death of her own mother, Anne, in 1985 at just 47.
