Possibly repeat test: Occult testing often leads to false positives. Abnormal test results may occur after eating meat, a nosebleed or gum bleed. It does not necessarily indicate internal bleeding. With stage iiib lung cancer and severe copd, i suspect your doctor believes there is really no benefit to further testing due to these very severe illnesses that will probably limit lifespan. ...Read more

Had a total thyroidectomy due to cancer. Now have pain on right side above chest with bloody stool and throwing up blood. Is the cancer causing it?

Seems unlikely: Hi. Was your thyroid cancer treated (surgery, radioactive iodine, TSH suppression)? What is your thyroglobulin (stimulated, and with TSH suppressed)? Not clear where your pain is; is it in the neck? Can you feel a mass? I think I can pretty well guarantee you that vomiting blood and having bloody stool have nothing to do with thyroid cancer. See your doc about the bloody vomit & stool & neck pain. ...Read more

Blood in stool past 2 weeks, no pain, does seem to have anal fissure that is healing but still some blood streaks should I be about cancer?

Blood in stool  past 2 weeks, no pain, does seem to have anal fissure that is healing but still some blood streaks should I be  about cancer?

Cancer not common: Blood per rectum is abnormal. Seems that you have explained it with the fissure. If you continue to be constipated, you shouldn't ever have to force out a bm, the fissure won't heal. Still advise you see GI doc for full colonoscopy. As often as 1 out of 3 times the full endoscopy wll find an additional problem. Usually polyps, but rarely (at your age) a cancer. ...Read more

How quickly do colorectal cancers progress once symptoms like blood in stool show? no symps just always have high anxiety about getting cancer.

How quickly do colorectal cancers progress once symptoms like blood in stool show? no symps just always have high anxiety about getting cancer.

Surveillance: The fact that you are worried -- whether or not the actual risk is worth it -- is a reason itself to begin getting occasional colonoscopies. If there's a family history, all the more reasons. In the absence of the non-polyposis colon cancer family syndromes, colon cancers are usually preceeded by benign polyps removable for cure. Ask whether you can start intensive surveillance now. ...Read more

Small cracker crumb size speck of bright blood in stool only, painful 2 pass happened 1 other time in teen no diaherra. Cause? Cancer??

Probably Hemorrhoid: Cancer is very unlikely. If you have a history of constipation, you may have developed a hemorrhoid. Generally, people will notice a speck (or sometimes more) of bright red blood on the toilet paper after a hard bowel movement. If there is blood in the stool (red or black/tarry which is older blood) or a substantial amount of blood, you should see a doctor to rule out other causes. ...Read more

Get evaluated: Blood in the stool can be due to bleeding hemorrhoids or a small tear from passing a large stool. His sitting for a living with little exercise is a risk for constipation. Blood in stools is also a possible sign of colon cancer. I recommend he be evaluated to determine the cause of his symptoms. Prostate cancer can be evaluated by blood test and exam. ...Read more

When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
