Hi, Thanks for posting in HCM. I have read your description and understand your concern. It appears that you are unnecessarily worried about certain things like cancer of colon and so on. Most commonly rectal bleeding takes place due to presence of fissures and/or hemorrhoids. It can be managed conservatively by means of taking high fibre diet and using stool softener medications. All you need to do to prevent its recurrence is avoiding constipation. However, if it occurs frequently and causes symptoms such as pain indicating infection, it needs to be evaluated and operated surgically. Kindly consult Surgeon in this regard for clinical evaluation and appropriate management. Hope the information provided would be helpful. All the best.
