Worried I have Skin Cancer

Hi Everyone

Last July while I was on holiday in Greece I was badly sunburnt on my left shoulder. Treated it the usual way and didn't think of it again until mid November I noticed an unusual mole on the same shoulder. 

It is irregularly shaped compared to my other moles and a bit darker but it's quite small only a couple of mm in length and width and does not appear to have got any bigger. I can't say for sure if it has always been there and has changed or if it is new as to be honest I never paid much attention to my moles.

I eventually went to my GP in February who referred me to Dermatology however due to Coronavirus my appointment was cancelled

Today I had a virtual appointment where I sent pictures to the people at the dermatology clinic and received a reply saying they want to send me for a punch biopsy to remove and look at this mole.

Is this bad? Does having a punch biopsy mean it's more likely to be serious ? I am a worrier at the best of times but this and the current Coronavirus situation has me very anxious.

I will probably talk to someone on the phone on Monday but if anyone has any advice it would be appreciated.

Thanks
