Could Hemorrhoids be a Sign of Cancer?

Posted on May 19, 2025

Hemorrhoids are merely swollen, inflamed vessels that form in and around the anal opening. However, certain hemorrhoid symptoms are similar to the symptoms of anal cancer and other diseases or conditions such as diverticulitis. As such, some people may conflate the side effects of hemorrhoids with cancer. But there are simple ways to detect the differences, and this post will help lead you to specialists, such as Hemorrhoid Doctors in Texas, who can give you a proper diagnosis.

Symptoms of Hemorrhoids

Hemorrhoids can form externally, meaning outside of the anus, causing itching, swelling and discomfort.  And, when they form internally, they may not be painful but hemorrhoid symptoms there may include rectal bleeding, the leakage of mucus, itching or even protrusion.

Symptoms of Diverticulitis

Diverticulitis is a condition describing an infection of your diverticula (these are small pouches found in the lining of your colon.) Symptoms include abdominal pain and distension, fever, and changes in bowel habits; some of these overlap with symptoms of colorectal or anal cancer.

Symptoms of Anal Cancer

Again, while hemorrhoids aren’t a sign of cancer, the two conditions share common symptoms. In fact, according to the American Cancer Society, symptoms of anal cancer include bleeding from the anus, abnormal discharge from the anus and itching around the rectum, all symptoms that are also associated with hemorrhoids. However, unlike hemorrhoids, anal cancer can also cause:

  • A lump or mass to form at the opening of your anus
  • A feeling of pain or fullness in your anal region
  • Changes to your bowel movements
  • Loss of control over your bowels
  • Swelling of the lymph nodes in your anus or groin

Hemorrhoids & Cancer: When to See a Doctor

Mild hemorrhoid symptoms may be resolved with homecare and lifestyle changes, including increasing your fluid and fiber intake to reduce constipation, making it easier to pass bowel movements and reducing pressure on your anus and rectum. At the same time, you should avoid sitting on the toilet for too long, or straining to pass a bowel movement. And, even if your stools are loose, try to address diarrhea as frequently passing stool can also irritate your anal region and contribute to hemorrhoid development.

However, if your symptoms persist or worsen, or if you experience any rectal bleeding, you should see a doctor right away. When you see a healthcare professional, you can distinguish hemorrhoids and cancer symptoms. Then, if internal hemorrhoids are to blame for your discomfort, you can request a consultation with the Texas Hemorrhoid Institute to discuss your treatment options.
