What do cancer lumps feel like? I've got one on my left rib (so not on boob) that I'm getting an ultrasound on, on Friday. It's quite soft, not hard. A bit squishy. Trying not to google and am trying to reassure myself that the GP had referred me for a "routine" not urgent scan... but I can't help but worry. Hoping it's just a cyst or fatty lump...
