Ok , whilst my experience is not like yours mostly because it is in the wrong bodily vicinity given that it is my ass in particular that had these problems , I could still share it , if only to lessen your worries that it will be cancer . and possibly to give you a laugh or two . Warning Wall of text incomingOk , so one Christmas in the past , I find that there was a bit of blood on the paper after having had a bowel movement . I figure it was no big deal , it would heal within a day or so . A few days later , it is still continuing to bleed , so I started to get a little worried and booked a doctor ' s appointment . I went there , and they said that it was just a fissure , and to use the prescribed cream to assist it in healing , and to eat a more fibrerich diet in order to avoid the problem in the future . The cream worked . for a day or so . Then it came back . At this point , the cream failed to do anything to fix the problem . So I had to book another doctor ' s appointment . Went back there , and they were starting to get concerned . They figured that it could be something like glutenintolerance , lactoseintolerance , crohn ' s disease . And yes , they mentioned rectal cancer as a possibility , although a very finite possibility due to young age . They booked me to do a few blood tests in order to narrow down what the problem could be lactoseintolerance or glutenintolerance . All the blood tests came back negative on that front . So they also had to schedule a colonoscopy with a gastroenterology specialist . Oh yes , the colonoscopy . That was fun . said noone ever . Oh the procedure is fine and all , especially if you are given an IV sedative , but that is not what the problem is with a colonoscopy . The problem is the preop , particularly the colon cleaner powder stuff you have to drink . I was assigned to have to drink three litres of a powder called ColonLYTELY lemonflavoured , or so they say two litres the night before , and one litre on the morning of the procedure . One person on the internet has said that ColonLYTELY it is akin to drinking sea water with half a lemon squeezed into it . They ' re not far off with that description . I even threw up a bit of it near the end of the first two litres of the stuff because it was so gross . Put me off of anything artificially lemon flavoured for quite a long time after . So basically , it was a similar ordeal to what this poor girl went through , but not quite as bad fistulastory . blogspot . com . au 20091014 oct 09 surgery 5 colonoscopyprepno . htmlSo with the colonoscopy done , I eventually found out what I actually had ulcerative colitis . It is literally as it sounds ulcers in the colon . Not pleasant in the slightest , but still thankfully not cancer . Although as it turns out that the condition does have an increased chance of causing rectal cancer . Yep , this little statement comes back to haunt me later on although I ' ll leave the details of that for you to ask if you want . So I get put on Mesalazine , and everything starts to clear up . Unfortunately , the story doesn ' t end there , but that ' s all I ' m going to give you for now . What I ' m trying to present with my experiences is that it could be something bad , it could be something that will affect your quality of life , but it does not mean that it is going to be cancer . Don ' t worry too much , I doubt it will be cancer . TLDR Started getting bleeding from the back passage , thought it could be rectal cancer at one stage , but turned out it was just ulcerative colitis . Not everything bad is potentially cancer and it is not completely likely that it will be .
