Tailbone pain

Hi all.

I've a strong family history of bowel cancer all on my mums side:  mum (45), uncle (55) and nanna (50 & 69). 

move had some symptoms but not sure if that's what they are:

the other day I did a poo but it was all just mucous

i have a sore tail bone a lot. It's larger on one side to touch. 

intermittent swelling in What I assume is Cecum

anemia 

pressure in bum that lasts about 3 days at a time. 

12 months ago I had a 2.5cm flat polyp removed.

as per genetic councillor i was meant to have one this week. 

but with corona it is being changed to August as the symptoms are vague. 

does any of this sound like real symptoms? Or just worry?
