Yes. It seems like the symptoms can be so vague that I often wonder "oh fuck is this cancer" when I can't quite pin down my symptoms. There isn't a lot of cancer in my family on my mom's side (I have like one great great aunt who died of childhood leukemia and a couple of smoking induced lung cancers) but I have absolutely no idea about my dad's side so sometimes when I go to the doctor it's just hanging out there in the back of my mind.
