Lump in my eyelid, painless, losing eyelashes too??

Lumps uneven in shape and when I close my eyelid, everyone can see it !

Been to see my GP, after 3 months of having this lump He examined my eye, asked multiple questions etc... confirmed to him, it's nearly 4 months now, lump the size of a Petit Pois Pea/Garden Pea. It's painless to touch?? Lost a few eyelashes, it's affecting my sleep because it's hard trying to sleep with this lump that shouldn't be there !! DR confirmed he's referring me to a Dermatologist, Opthalmologist and also a specialist. DR said in his own words " He's sure it's cancer, more than sure, but we must wait for all the above professionals confirmation before we talk treatment, surgery etc.......

He explained it's probably BCC or SCC Also he was rather worried because my mother passed away 4 years ago due to Melanoma Cancer

I'm petrified, lost, up and down, confused and above all, married to the love of my life only four months ago and I'm not sure what to do ??

Please, any help or conversation would be appreciated.

Thank you
