Second Opinion possibly?

Hi, I’m looking for advice or someone thats found themselves in similar situation.

At the start of Dec a mole behind my left thigh that’s been there since birth became itchy (on and off) so I decided to take a look, noticed it wasn’t the brow round mole I remembered it to be previously, so called dr, told to keep photo diary each week. In that time noticed it changing again, blurry faded border, brown spots within it, then it had what was like a white head develope in the centre which then became black looking, and now looks like a crater/hole in the centre. (Should mention whole mole from edge to edge gone from 6mm-8.7mm)

I was urgently referred to dermatologist clinic for check as dr knows fabcy history of cancers, brother recently passed of CUP (cancer of unknown primary) mum non Hodgkin lymphoma and aunty last year lung cancer with a BCC on her nose at same time.

So appt was yesterday at dermatology, giving my concern of the above I was hoping I would have this removed and biopsied which my dr was convinced they would poss do too but she took a look through the dermascope (approx 10seconds or so Rolling eyes) and had photos took, and told to go back in 3 months to check again Rolling eyes

I left the appt feeling not a whole lot of comfort or confidence that this was the right solution. So I’m concoderibg a second opinion but I really think this needs to be removed.

I’m 38, very fair skin and I do have a fair good few freckles and moles over my body.

Thank you in advance for any information or advice given.
I will attach the final image taken (most recent) below which was taken approx a week ago.
