Katherine Ryan led the comedians at the Teenage Cancer Trust Night of Comedy on Tuesday, just days after revealing she has been diagnosed with skin cancer.
The comedian, 41, shared on Friday that she’s battling melanoma for the second time after having a mole on her arm removed.
But Katherine isn’t letting her health woes hold her back as she arrived at the Royal Albert Hall in London to deliver a fantastic show alongside A-list comedians including Scott Bennett, Finlay Christie, Romesh Ranganathan, Micky Flanagan and Jack Skipper.
She dressed casually for the occasion, sporting a chic baby pink sweatshirt with croissant embroidery and light blue denim jeans.
Katherine completed her look with beige trainers and appeared in high spirits as she posed for several photos before the show.
The star’s appearance at the event came just after she updated fans on her health following surgery for the second time in a week.

The comedian, 41, shared on Friday that she’s battling melanoma for the second time after having a mole on her arm removed
The comedian announced that she had been diagnosed with a cancerous mole on her arm last week and took to her Instagram Story to share an update, uploading a photo of her arm covered in a plaster.
Katherine captioned the update: ‘Done,’ with a tick and a red heart emoji.
The TV personality paid to have the mole removed privately last week, but after doctors discovered it was cancerous she had to undergo another procedure.
It’s the second time Katherine has been diagnosed with the disease, having been diagnosed with Stage 2 cancer in 2004.
Speaking on her podcast, Telling Everybody Everything last week, she explained: ‘The only reason that they agreed to remove it was because I went to a fancy private place in South Kensington and I paid them a grand.
‘I don’t know if on the NHS they ever would have removed this mole.’
While the Canadian comic did not trust the NHS would have removed the mole, she revealed she faced different problems while seeing private doctors.
She explained that she had paid £300 for a seven-minute consultation with a doctor, who wrongly informed her the mole wasn’t cancerous.

Yet she was inspired to keep pushing with her concerns after following Teddi Mellencamp’s journey.
The Real Housewives star, 43, has been battling skin cancer since 2022 and this year revealed doctors had found three tumours in her brain.
Katherine recalled: ‘He gave me the news that I wanted! I think it’s really easy to take a diagnosis of you’re healthy and walk away, you go ”great I’m healthy” and you don’t think about it again because that is the easiest news.
‘But the mole kept changing – I know a lot about melanoma, I had a melanoma as a very young woman, stage two on my leg – and I’ve spoken about that before.’
She continued: ‘Even that didn’t look traditionally like melanoma to me, fair enough it had some discolouration and asymmetry and a bit of black and red. It was a flat mole, not that bad and not that big, but it was stage two melanoma so that was bad.
‘I had to have full general anesthetic and surgery to have a golf-ball size of my leg because – if you know about melanoma, you know it’s a deadly form of skin cancer and it spreads quickly.’
Discussing her current cancer battle, she went on: ‘I just felt like this mole wasn’t right. It’s on my arm, I showed pictures of it on social media, this is like the hole from having it removed.
‘I went in and I wanted the doctor to remove a bigger piece of it and stitch it up in a straight line.

Meanwhile, Micky, 62, who hosted the show, sported a blue T-shirt and dark blue denim jeans as he larked around for the camera

Romesh, 46, looked upbeat, smiling broadly for the cameras in a pale blue button-up shirt and black baggy trousers

YouTuber Finlay wore a baggy black sweatshirt and dark blue denim jeans with exposed stitch detailing
‘But even when he looked at it, he was like “not melanoma, totally fine, I will do the shave and send it away for histology and if there’s any borders that we missed, then we will do the deeper cut”.’
Yet the test confirmed that she needed the deeper cut, and she continued: ‘It just feels crazy to me, like what could have happened if I hadn’t been my own advocate – and I will continue to be my own advocate.
‘If I hadn’t pushed, if I had taken that good answer the first time and walked away. Then I would have had melanoma just growing and spreading in my arm and I would say “oh no the doctor says it’s fine, it’s fine” and god knows how far that would have gone.’
Katherine shared her shock at the diagnosis, revealing how she has been careful to protect her skin.
Explaining how she broke the news to husband Bobby Kootstra, she shared: ‘I was upset when I called [Bobby] because I feel very lucky but I also feel like what the f**k?

Scott Bennett also appeared in good spirits, wearing a smart black zip-up jacket and beige trousers, beaming for the camera

Josh Widdicombe, 41, looked equally cheerful, posing in an orange striped T-shirt and a dark green overshirt
‘It’s not ideal to have melanoma twice in your life and I obviously have a genetic predisposition, I am someone with type one, Celtic skin, I have over 100 moles.
‘I don’t go in the sun, I wear SPF all the time, I cover my body, I cover my arms, I cover my face, but here’s my second go with melanoma that I know of! I’m thinking f**k what other moles do I need to get checked?’
She added in a TikTok video: ‘This time luckily I caught it early, I don’t think it has spread.’
It’s the second time Katherine has been diagnosed with the disease, having been diagnosed with Stage 2 cancer in 2004.
She said previously: ‘The cancer wasn’t that serious. It wasn’t into my lymph nodes, I didn’t have to have chemotherapy.
‘It did recur, but it was easily dealt with. I feel like I was really lucky just to get that lesson, that little smack on the a**e of “Hey, wait a minute. Listen to your body, here.”’
She previously joked that moving to the UK had been the ‘best thing’ for her because of the lack of warm weather, she told The Guardian: ‘I just joked that it was free lipo. If you’re prone to skin cancer, then living in the UK is the best thing you can do.’
Katherine was born and raised in Canada but moved to London in her early twenties to pursue her comedy career.

The comedian and her childhood sweetheart Bobby have two children together Fenna, two, and Fred, three.
She also has a 15-year-old daughter Violet from her previous relationship with boyfriend Alex Edelman.
Katherine has also been battling Lupus and previously discussed her struggle with the disease – having first experienced symptoms back in 2007.
She had just moved to London when she first began to suffer with sore joints, fatigue and rashes.
In an interview with The Mirror she explained: ‘I had really low white blood cells, but no one seemed particularly alarmed about that. There was a lot of frustration with doctors who didn’t know what was wrong and didn’t investigate. I felt quite fobbed off.’
Following various appointments with an array of specialists, she added that she was told she could have ‘ringworm’ whilst another took a guess with ‘leprosy.’
Desperately Katherine visited A&E, where a nurse there first suggested that she might have Lupus.
After almost a year of trying to get a professional diagnosis she was finally told by a dermatologist that she had systemic lupus erythematous.
Whilst there is no cure for the long-term condition, it can be treated and controlled with medication to prevent it from getting worse and lessen flare-ups.
As well as being a stand-up comedian appearing on shows such as QI and Have I Got News For You, Katherine is also well-known for television programmes such as Duchess and Meet the Richardsons.
Fans know her as much for her glamorous looks and outfits as they do for her outspoken nature on everything British.
