Hi I'm 17 years old and I have some worrying symptoms of bowel cancer for about a year now, I've had these cuts (anal fissures?) that I can see starting from near my anus to near my lower back two of these cuts have recently developed and the one closest to my lower back has a lump or skin tag just beside it I've only just done some research now because I didn't understand the severity of this, it says I have secondary anal fissures which are multiple painless cuts but I just want to be sure it's not cancerous, I guess I could say I've got constipation but it's not really a struggle for me too poo I feel no pain I just see these cuts or tears could this be bowel cancer?
