Skin lesion

I recently visited my GP due to a lesion on my arm that was growing and was constantly bleeding profusely when knocked.  My GP felt it was a pyogenic Granuloma and gave me some medication, this reduced very slightly burn the growth remained, so I reached out again and now the GP has referred me for an urgent referral with a dermatologist.  Looking at family photos I have had a mark in the location since 2017 and a photo in 2024 showed a changed and now it is very much worse.  Anyone had an experience like this or any ideas of what this may be as I am now starting to worry and have another 10 days before the dermatology appointment?  Many thanks
