What is this? Pic included

My DP had this appear on his back some time ago now. It started off small and has grown over time. It’s not painful and just feels like a hard lump.

Could it be a cyst?

I also reckon it's a cyst

Or a lipoma, which is a harmless fatty lump.

Probably a sebaceous cyst - I get them on the back of my neck just as you described. Try rubbing your finger over it/gently squeezing it - if your finger smells then that's pr baby what it is

Sebaceous cyst? Give it a squeeze. Don’t forget to film it.

We have tried squeezing but nothing happens! Anything else we can try?

Get it checked out but it looks a bit like my dermatofibroma. GP said it was nothing to worry about.

My dd also had a dermatofibroma. To be fair, the GP told me to keep an eye on it as, if it changed, it could be something to worry about. She had it years and I do think now it is less significant, smaller. If I were you, I would get it looked at by a GP. Not because it is a worry, but because you need to know what you are dealing with.

If it's a sebaceous cyst nothing will happen when you squeeze it, but your finger might smell

I’ve got a sebaceous cyst and DH squeezes thick smelly cheesy stuff out from time to time. Sebum. Hence the name.
