I had a sudden, painless discharge of a clear, very slightly reddish brown liquid from my rectum, leaving a wet area on the seat approximately 6 X 4 . I did not even feel it when it happened -- I just felt like I had sat on something wet. However, my pants had a very scant amt of what appeared to be rust colored stool and large watery stain. I have had 3 or 4 episodes of a small amount of bright red blood in my stool in the past 4 or 5 months, but nothing major. I have been having normal stools, but can t always tell when I am done or I feel like I can t get the stool all out. I am a 71 year old female. My mother died from GI cancer, so am a bit concerned.
