Rectal cancer up among younger adults

A new study finds rectal cancer rates are rising among adults under 40, the journal Cancer reported Monday.

Using National Cancer Institute data, the study found cancer rates remain low but are increasing among both men and women and across racial groups.

Dr. Joshua E. Meyer, the study’s lead author, says doctors should consider rectal cancer as a real though remote possibility when assessing patients with bloody stools or other abnormal bowel movements.

“We do know that in younger patients there could be a delay in diagnosis,” Meyer said. “When doctors see a patient who is bleeding or has some of these other symptoms I hope doctors put this on the list.”

Hemorrhoids remain the most likely cause of a bloody stool, but misdiagnosing cancer as hemorrhoids could allow the cancer to grow and spread throughout the body, he added

Rectal cancer rates rose an average of 2.6 percent from 1973 to 2005, with the increase starting in 1984, the study found. During the same period, colon cancer rates remained flat.

Meyer, who is in the Radiation Oncology Department at Fox Chase Cancer Center in Philadelphia, said the reason for the increase is unclear. If changes in lifestyle such as a fatty diet were the cause, then colon cancer rates should also be rising, he said.

Rectal cancer remains rare, about one in every 238,000 people during the time period of the study. Colon cancer was almost three times as common.

The journal Cancer is published by the American Cancer Society.

      Then you tell your doctor that he works for you and to run the test. If he refuses, fire him. Geez, how hard is it?

    Those are some insensitive comments. We need to take this seriously– Rectal cancer runs in my family, and I would like to know why it's appearing in younger people.

      First intelligent comment. I am wondering if it might be something in the environment, such as some pollutant.

      You went to a comments section on rectal cancer and expected a mature conversation? LOL, I knew better. This is disturbing, however. This may be due to an environmental pollutant, a food pollutant, or potentially even HPV transmitted through anal intercourse. We need to find out.

    Since HPV (human papilloma virus) can causes cervical cancer, perhaps it can also cause an increase in rectal cancer due to anal intercourse...a sexual history should be included in the work-up..

      The same thought crossed my mind. If there were a large amount of homosexual men and women who have anal sex that are coming down with RC, this would be a primary suspect.

      This is exactly what I thought! I thought it was a no brainer, especially when the article mentioned that something like bad diet would also show an increase in colon cancer, which isn't happening. People are breaking social and sexual taboos and exploring their sexuality more, which is great, but because it is still taboo people don't know how to protect themselves, and thus spread diseases. And BTW Dave, heterosexuals have anal sex, too. If a guy has HPV and has anal sex with his girlfriend, she's the one who could get RC.

    Rectal cancer like all cancers, arise when certain states of inflammation turns on an oncogene, so any condition like constipation, hard stool due to a low fiber diet, and rectal intercourse, among other possible reasons. It has to be taken seriously, because the quality of life in such a patient can be quite terrible. There is no one simple reason, it is multifaceted, but nowadays, more young people are taking risks that are new. Once thought to be a sturdy area, that could take a banging, we wee now it is a delicate zone, not created for abuse.

    While certainly not the only cause of anal and rectal cancers, HPV is certainly high on the list. How did Dr. Meyer miss this as a potential cause?

    Human Papiloma Virus (HPV) transmitted by rectal sex is the most likely culprit.

      Rectal intercourse is not necessarily the vehicle that brings the cancer causing virus from cervix/vagina to the rectum/anus area. They are very close neighbors ! Just sitting and moving move fluid backward and forward. I do hope, it doesn't become a common belief that rectal or anal cancer means that anal intercourse is the culprit with its negative connotation.

    From Wiki: "Examination of squamous cell carcinoma tumor tissues from patients in Denmark and Sweden showed a high proportion of anal cancers to be positive for the types of HPV that are also associated with high risk of cervical cancer (90% of the tumors from women, 100% of the tumors from homosexual men, and 58% of tumors from heterosexual men). In another study done, high-risk types of HPV, notably HPV-16, were detected in 84 percent of anal cancer specimens examined."

      I am glad for you but as young people we are prejudiced against by the medical community. I have had doctor after doctor DENY me for doing a colonoscopy because I am TOO YOUNG. Even my insurance refuses to pay for it because they feel it is not necessary. I am so sick of these insurances deciding for my health what is and is not necessary. I pay them alot every month for health insurance and then they turn around and deny me rights to screen for illnesses?? Obviously its all a ploy. They want you to get sick so you can be a patient for life. They make no money when you have no illnesses. Its all a twisted scheme.

      @ Sam – You need a more aggressive doctor. I'm a bit older than you but still under "typical" colon cancer age. I asked my doctor about it, she asked me why I thought I should be concerned, and I explained a family history, not of cancer but of polyps. Done. For many years I went to an assembly line doctor, then I wisened up.

    Sam, your post is a perfect example of our broken health care system. Until we can free Americans from the profit driven employer finance method of providing health care coverage we are at the mercy of the corporate board rooms.

      A balance has to be struck. Whether it's an employer or government financed system, it has to have the ability to say "no" sometimes. You shouldn't be able to order up a test that costs several thousand dollars unless there is something indicated wrong - symptoms, family history, or whatever. I assume in Sam's case that there was some reason aside from hypochondria that the test was necessary but if that's incorrect, it should be denied...unless it's private pay.

      I pay nearly 300 bucks a month simply to be able to PAY for health insurance. You are paying them to be able to pay them. That is what the premiums are all about. If I feel that I need a test to be sure I am not going to drop dead of something, that is my business. They always get paid for it so why are you concerned? The doctor should have ZERO say in what I feel is necessary to take care of this one body I have.

    If it is HPV related, don't sit on anything anymore. Denmark and Sweden study is missing one portion of critical information: the rate of HPV and its reservoirs in people without cancer. With something as endemic as HPV, you can associate this virus to nearly any disease. Probably a dietary or environmental cause such as hydrocarbon carcinogens from high heat cooking.

    People,
    Be decent. I have family member undergoing Chemo and Radiation at this moment for Rectal Cancer. This is very serious and painful. A family man who had routine scopes over the last 10 years and the Docs missed this slow growing tumor. Now in Stage 3. He has been proactive for years and years, regarding physical exams, and scopes since having a polyp removed in the early 1980's, and now this. Grow up w/ some of these stupid postings and have some humanity. For the folks who have been helpful and clinical in focus, Thank you.

    An anus is built and designed to evacuate the bowels–not for sex. The HPV virus is definitely a contributing factor, however, the increasing number of people having anal sex can not be dismissed as a major contributing factor as well.

    I think that more and more people are doing the unnatural thing and going into the exit door during sexual relations, that this is why there is such an increase in this type of cancer. All the stuff people are doing in that area is not natural, even putting all kinds of objects and chemicals in there.

    There has been an unusually high percentage of people with cancer as the years have passed, and it only seems to get worse. I think we need to stop and ask ourselves what is going on? Is it the water we're drinking? The food we're eating? The common chemicals we run into everyday in plastics? What is going on here? And are there people who know the truth, yet continue to allow these things to occur in the quest for the all mighty dollar? Google it!

    There is a very good reason why this is coming up now. Beginning in the late 80s the number of young people (15-35) engaging in anal sex on a regular or occasional basis increased. What not many people realize is that the same viruses that can cause cervical cancer are also implicated in most cases of anal cancer.

    Hence, changes in sexual attitudes and behaviors are two of the reasons we have seen a rise in anal cancer rates among young people.

    In Stage 0 rectal cancer, the tumor is located only on the inner lining of the rectum. To treat this early stage cancer, surgery can be performed to remove the tumor or a small section of the rectum where the cancer is located can be removed. Radiation treatment, given either externally (beamed in from the outside) or internally (radioactive beads are placed inside the rectum) may be considered. .;...
