Katherine Ryan issued a health update on Monday after undergoing surgery for the second time in one week. The 41-year-old comedian revealed that she had been diagnosed with a cancerous mole on her arm last week, after previously having melanoma when she was younger. Sharing the news on her Instagram story, she uploaded a photo of her arm which was covered with a plaster. Captioning the snap, she wrote, 'Done', with a tick and a red heart emoji. The TV star paid to have the mole removed privately last week but had to undergo another procedure after doctors discovered it was cancerous. It's the second time that Katherine has been diagnosed with the disease, having previously battled 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." Katherine said she faced some issues while seeing private doctors as she explained that she had paid £300 for a seven-minute consultation with a doctor, who incorrectly informed her the mole wasn't cancerous. However, she was inspired to keep pushing her personal concerns after following Teddi Mellencamp's journey. The Real Housewives star has been battling skin cancer since 2022 with doctors finding three tumours in her brain. Katherine said: "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 anaesthetic 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. "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".' Her test confirmed that she did in fact need the deeper cut as she said: "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 revealed her diagnosis had taken her by surprise after saying she had been careful to protect her skin. Explaining how she broke the news to her husband Bobby Kootstra, she recalled: "I was upset when I called [Bobby] because I feel very lucky but I also feel like what the f**k? "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?" "This time luckily I caught it early, I don't think it has spread." The comedian comic had previously revealed that moving to the UK had been the 'best thing' for her due to the milder 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." However, melanoma is not Katherine's only health concern as she is also battling Lupus, with her symptoms dating back to 2007. Katherine had just moved to London when she first began to suffer from sore joints, tiredness 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." After almost a year of trying to get a professional diagnosis she was finally told by a dermatologist that she had systemic lupus erythematosus. 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. It's the second time Katherine has been diagnosed with the disease, having been diagnosed with Stage 2 cancer in 2004.

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.
