Katherine Ryan has been diagnosed with skin cancer for the second time in her life, she told fans on her TikTok channel on Friday, March 21.
The 41-year-old Canadian comedian posted a video of the news, explaining that she was originally concerned about a mole on her arm but was told by a doctor that it was nothing to worry about.
It is the second time Ryan has fought the disease, having been diagnosed with Stage 2 cancer in 2004.
There are two types of skin cancer: melanoma, the deadliest form, with around 13,000 new cases diagnosed each year in the UK, and non-melanoma, of which there are more than 100,000 new cases diagnosed every year.
