Do all colon cancer patients have rectal bleeding?

Do all colon cancer patients have rectal bleeding?

Not always.: Early in colon cancer, there are typically NO symptoms until the cancer tumor grows large enough that it begins to cause problems in the digestive tract. Small, asymptomatic cancers can be found by screening colonoscopy.

Do colon cancers continue to bleed or do they stop? Haven't had rectal bleeding for over a year but did have bright red rectal blood before. I'm 26.

Typically yes: If the bleeding you had one year ago was due to colon cancer, you would have had a number of progressive symptoms by now, so I wouldn't worry (plus colon cancer is very uncommon at age 26). If however bleeding recurs or persist have it evaluated. ...Read more

Had rectal bleeding for a few weeks 2.5 years ago. No bleeding since. Dr said it was likely fissure that healed. Would colon cancer continue to bleed?

Rectal bleeding: If your rectal bleeding has come back, then okay to get in to your doc for evaluation. More likely this is a hemorrhoid or recurrent fissure. Cancer in your age group is very low incidence. However, an exam under anesthesia will lead to a diagnosis, and treatment. Good luck. ...Read more

Is rectal bleeding associated with prostate cancer?

Possibly: Depending on the stage of the prostate cancer, rectal bleeding can be present. However, if it an early stage prostate cancer, rectal bleeding is generally not associated with prostate cancer. Also, previous radiation treatment for prostate cancer may cause rectal inflammation and cause subsequent rectal bleeding but this generally resolves over time. ...Read more

Bright red rectal bleeding stopped 2.5 years ago -- had sigmoidoscopy then and didn't see anything. Does cancer usually continue to bleed?

Bright red rectal bleeding stopped 2.5 years ago -- had sigmoidoscopy then and didn't see anything. Does cancer usually continue to bleed?

Hemorrhoids: Bright red blood may signify a hemorrhoid and that was self limiting. The sigmoidoscopy showed that no cancer was present in the sigmoid colon. Your doctor wanted to know your family history of cancer and cancer would continue to have episodes over 2+ years. Talk with your doctor to discuss your concerns. People need a screening colonoscopy at 50 or sooner with a risk factor. ...Read more

Dr diagnosed external hems 4 weeks ago. Had rectal bleeding 3 times last week. Rectal exam showed none today. Was blood caused by rhoids or cancer?

Dr diagnosed external hems 4 weeks ago. Had rectal bleeding 3 times last week. Rectal exam showed none today. Was blood caused by rhoids or cancer?

Probably: If the blood was bright red and not mixed with stool, it is quite likely that you bled from the hemorrhoids. However to be sure, I recommend that a proctologist or colorectal surgeon start with a simple flexible sigmoidoscopy which visualizes the descending colon and would be good evidence in ruling out internal hemorrhoids, benign polyps, ulcerative colitis, or malignant growths. ...Read more

Likely not: There are many reasons for rectal bleeding, including internal hemorrhoid, inflammatory bowel disease and diverticulitis, among others. Colon cancer is certainly a reason, but at your age, unless you have a huge family history of colon cancer, it is way down on the list. You should get a colonoscopy for sure, but don't go into it with the worst case assumption ...Read more

Is rectal bleeding a sympt of ovarian cancer? I am getting conflicting info on the web. I read o cancer doesn't erode into the organs so it doesn't cause rectal bleeding. That was from a gyn oncologis

Extremely unlikely: Ovarian cancer can, with enough time, can invade into the rectum and cause bleeding, but it would have to be at advanced stage at that point. In reality, it's rare for ovarian cancer to present with rectal bleeding, especially at your age. Far more likely there is a gastrointestinal issue. See your doctor to be evaluated for this. ...Read more

I passed a very hard stool just before christmas which caused me slight rectal bleeding and piles, I also have anxiety and am very worried it's cancer?

Well first, take a: Deep breath in and then blow out some of your fear. Statistically, the bleeding was most likely related to your constipation/ hemorrhoids. If you have more than that 1 episode then just get it checked by your doctor. For the hemorrhoids - you need to keep stool soft. Drink at least 64 oz of water a day. Try to work the junk food out of your diet and instead enjoy at least 5 servings of vegetables. ...Read more

BRBPR due to...: This may just be hemorrhoids from straining but bleeding from rectum (brbpr) may also indicate anal fissures, proctitis (due to infection, inflammatory bowel disease, radiation therapy, stercoral ulcers, rectal prolapse, trauma, etc.) or a bleeding source further upstream.

Would bowel cancer alter blood tests? Abdo pain, rectal bleeding and back ache for 12 mnths. Dr won't refer for colonoscopy as I'm 27 + blood test ok

See different doctor: Rectal bleeding warrants investigation. It is unlikely that you have colon cancer and colonoscopy is probably not required, however, you still need to be evaluated for the cause of rectal bleeding. It may be hemorrhoids, even that needs to be treated. If your current doctor is providing satisfactory care, it is reasonable to see another doctor.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex. ...Read more

Loosed/mushy stools for months, constant bloating, fatigue, loss of appetite & weight. No rectal bleeding or pain. Anxious about colon cancer. I'm 25.

Rare but possible: At 25 it would be very unusual to develop colorectal cancer and almost always would be related to an inherited family predisposition like having 2 or more first degree family members with colorectal cancer, ovarian or endometrial cancer or someone with a lot of polyps. At your age these symptoms are usually not cancer but you absolutely see your doctor for a check up ...Read more
