Hi, yesterday night I was suddenly bloated and had some stomach ache. I went to the washroom and there was this blood spot in one of my stools and also in the toiled paper when I wiped. This doesn't really surprise me since I have had bleeding before (a couple of years ago) The first time I experienced this kind of anal bleeding was after the first time I had sex. I didn't think it was related since the blood came from the anus, some months later I had gas and sharp pain around the anal area and some time later I had a lot of bleeding again so I saw a doctor and he told me it was probably internal hemorroids. Another doctor asked me if I wanted a colonoscopy or if I preferred to wait and see if I had bleeding again. I decided to wait since the idea of having a colonoscopy scared me. So yesterday I had little bleeding, only that spot of blood but now I'm having a kind of burning pain in my right lower back. I'm worried about cancer thought.
Hi and welcome to the forum! I am glad that I can help you.
You would like to know whether burning pain in the right lower back may be a symptom of colon cancer.
Colon cancer is a condition that is characterized with anemia, constipation, ileus (sudden stoppage of the peristalsis due to colon obstruction), weight and appetite loss. Usually, any type of cancer is silent (meaning no presence of pain). Colon cancer is not common in young individuals unless there is a family predisposition for polyposis or colon cancer. Pain in the lower back is usually due to a kidney condition: infection or kidney stones.
Urinary infections are characterized with a frequent need to urinate, pain in the waist or discomfort during urination, changes of the urine (piuria or milky urine) etc. In females, pain may appear during menstruation due to ovarian dermatome (the skin has sensitive nerves coming from the same spinal nerve that serves the ovaries).
According to the data that you described, it is not likely that you experience the back pain due to underlying colon cancer. You may consider having a laboratory test of your urine as well as a bacterial culture with antibiogram to rule out possible urinary infection.
