Yesterday, I saw my oncologist for one of my every-three-month follow-up visits. As always, I went armed with my list of questions -- which is really my list of worries -- and one by one, I rattled them off. On a little sticky note, I had written:

• Lymph node
  
• Digital mammogram
  
• Next MRI
  
• Heart
  
• Colonoscopy

And this is what my doctor had to say about my concerns of the day:

The pathology results are in -- the five small polyps removed from President Bush's colon on Saturday are not cancerous.

White House Press Secretary Tony Snow announced today that microscopic evaluations of the five polyps confirm the preliminary diagnosis: tubular adenoma -- or as Snow called them: "garden variety polyps."

Nearly two-thirds of all polyps are adenomas, the vast majority of them tubular adenomas. It is not uncommon to find these polyps in routine colonoscopies.

President Bush is keeping up with his colon cancer screenings. Good thing -- because five small growths were found and removed during his latest scan on Saturday.

The polyps found inside his large intestine were all less than one centimeter in size and did not appear suspicious. Still, they were sent to the National Naval Medical Center in Bethesda, Md., to be microscopically examined for signs of cancer. Polyps can turn into cancer, so finding them early is the best way to prevent the disease and improve the odds of surviving it. It takes 48 to 72 hours for pathology reports to come back, but the majority of polyps this size are unlikely to be cancerous.

Bush is no stranger to polyps. In 1998, after a similar scan, two polyps were found. In 1999, two more surfaced. And while none were found during his 2002 screening, he has become a prime candidate for regular examinations. For the general population, colonoscopy tests are recommended every 10 years.

A report in Gastroenterology advises that if you need a repeat colonoscopy due to an incomplete colonoscopy, you should find a specialized medical center for the procedure.

An incomplete colonoscopy occurs when the full length of the colon, up to the point where it joins the small intestine, cannot be examined. Being a woman and being elderly increases the chance of having an incomplete colonoscopy. Having the procedure done in a private office also increases this likelihood.

Dr. Hemant A. Shah and a research team from the University of Toronto found that out of more than 331,000 colonoscopies, 13.1 percent were incomplete.

Individuals who underwent colonoscopy in a private office were more than 3 times as likely to have an incomplete procedure as those having their procedure in an academic hospital.

It seems like the rates of many cancers are skyrocketing lately, so it's refreshing and inspiring to hear that all our medical advances have paid off -- That's Fit recently reported that screening technology has lead to a significant drop in the rates of Colorectal Cancer.

The screening process for colorectal cancer typically consists of a colonoscopy or a sigmoidoscopy, and it's recommended that men and women over the age of 49 should get screened for Colorectal cancer regularly.

Getting screened for cancer isn't always the most pleasant thing, but it's worth it to save your life.

Prescription weight-loss drug Xenical hit drugstore shelves on Friday with a new name -- Alli (pronounced: "Al-eye") and with a new non-prescription strength. The newly-named drug is to be more effective with less unpleasureable side effects. Still, there's a problem surrounding this drug, regardless of its name. It's thought to cause colon cancer.

The nonprofit group Public Citizen says Alli, made by GlaxoSmithKline, has been shown in mice studies to cause pre-cancerous lesions in the colon. Since there are no long-term studies on humans, this group believes the FDA should not have approved the drug for non-prescription use. It's not clear whether or not the pre-cancerous spots will lead to colon cancer but the mere suggestion that it might is enough, says a Public Citizen spokesperson.

"What we do know is that these lesions occur much more frequently in people who do get colon cancer," he said. "Why do we recommend that everyone get a colonscopy at the age of 50? Because you pick up on these polyps when you do one. And, even though not all of the polyps are pre-cancerous, no (doctor) does a colonscopy without removing every single polyp that is found. And you do this because you know if you don't, it greatly increases the chances of getting cancer."

In the January issue of the Journal of the National Cancer Institute, findings were published that says calcium seems to protect high-risk people from developing polyps in the colon. Polyps are growths in the colon and some can become cancerous over time.

Patients, who had a history of benign polyps, either took 1,200 milligrams of calcium in supplement form or received a placebo daily for four years. In this study it showed that calcium use was associated with a 17 percent lower risk for polyp recurrence.

"It really does look like calcium interferes with carcinogenesis in the large bowel" researcher John A. Baron, MD, tells WebMD. "The fact that this reduction in risk persisted for years after people stopped taking calcium is amazing".

Baron also stated that it is still not clear if the benefits outweigh the risk since some studies have linked calcium treatment with an increase in prostate cancer risk.

On the flip side a University of Arizona epidemiology professor Maria Elena, PhD, worries that the findings will make people think that all they need to do to protect themselves from colorectal cancer is to increase their calcium intake, which in men high doses can be dangerous.

The best way to prevent colon cancer is to get a colonoscopy when you turn fifty and make sure you have follow-ups. That is not as easy as popping a pill but its true.

The American Cancer Society recommends that adults aged 19 to 50 take in 1,000 milligrams per day of calcium and that those over 50 get 1,200 milligrams. The guidelines stress that the calcium should come primarily from food sources and not supplements.

In 1971, when it was evident cancer deaths were rising, President Nixon and Congress declared a war on cancer. Finally, after 35 years, it seems we are winning the war.

Experts say the absolute decline in cancer deaths is quite amazing -- because our population is both growing and aging, both of which could contribute to an increased cancer death rate. But prevention, early detection, and early treatment are working wonders and are saving lives for three of the most common cancers -- breast cancer, prostate cancer, and colorectal cancer. More and more men are also surviving lung cancer due to cessation of smoking more than 20 years ago. The female lung cancer death rate is not declining, however, due to continued high rates of smoking.

The highest drop in deaths among the major cancers was for colorectal cancer -- thanks to effective screening methods. Deaths dropped by 1,110 for men and 1,094 for women.

According to an American Cancer Society review of U.S. death certificates, cancer deaths declined by 369 between the years 2002 and 2003. Between 2003 to 2004, the decrease was 3,014 -- more than eight times greater.

Experts predict cancer deaths will continue to decline over the years -- although some expect the obesity epidemic, which increases risk for all cancers, to pop the cancer death rate back up in the long run.

Battling cancer can at times feel like slowly paddling upstream against currents that are both forceful and unforgiving. Sometimes reprieve comes only when we find others in the same boat, others submerged in their own rough waters, others who truly know what it's like to navigate a dreadful disease.

I am lucky -- in an odd sort of cancer way -- because I had breast cancer. Many women have breast cancer. And while this really is a horrible fact, it makes for a great sea of support. At times when I felt I was drowning in cancer, I reached for my lifeguards -- the women who paddled before me, the women paddling alongside me -- and they coached me, guided me, saved me from one the worst side effects of cancer. Isolation.

I have rarely felt isolated in my cancer journey and as a result, I have not thought much about this lonely cancer consequence. But I am thinking about it now -- thanks to a reader who has courageously shared her story with me, in hopes of locating someone in her same boat, in hopes of creating connections with other survivors who share the challenges of her disease.

Tanya has anal cancer. She was diagnosed one year ago -- during a routine colonoscopy -- with squamous cell carcinoma in-situ in her anal canal, on the wall between the anus and vagina. Previous abdominal discomfort, much like dull menstrual pain, preceded Tanya's screening but she was sure it was due to menopause. She was 53 at the time.

But it wasn't menopause. It was cancer. And it was devastating for Tanya who was spared radical surgery in exchange for a combination of radiation and a chemotherapy called the Nigro Protocol. First came a mitomycin push followed by four to five days of 5-Fluorouracil. Radiation came next -- for six weeks -- and then Tanya endured another round of the same chemotherapy regimen.

"The treatment was brutal," Tanya says. "By the end of the sixth week, I was in a lot of pain, especially since the affected area had a lot of traffic and could not exactly be decommissioned and allowed to heal."

Although she was told by her oncologist she tolerated her treatment well, Tanya says it was pure hell.

Tanya's treatment ended in March and an August biopsy revealed she is doing just fine. Her cancer appears to be gone. What is not gone, however, is the discomfort that still plagues her -- both physically and emotionally. And while the physical scars are simply terrible -- she feels pain during urination and bowel movements and is currently unable to have intercourse with her knight-in-shining-armor husband -- the emotional isolation is overwhelming distressing.

"I have not shared this experience with too many people since I feel awkward discussing that part of my anatomy and because the condition is so uncommon," Tanya says. "I would, however, be most grateful to discuss any or all of this with someone who has been through the same experience."

If you have been in Tanya's same cancer boat, have paddled similar waters, or know someone with whom she might connect, please consider contacting this brave survivor at sultana@cyberight.net.

A colonoscopy camera lets the physician check for abnormalities inside the colon. These can include cancerous or precancerous growths. The doctor guides a flexible scope though the colon, that can take about seven minutes, he then spends on average another six minutes withdrawing the scope evaluating inside of the colon.

The New England Journal of Medicine published a study that found colonoscopies that took a longer time to complete found more abnormal growths. Faster testing was shown to miss some abnormalities. Doctors who spent more than six minutes withdrawing the colonoscopy tube found more abnormal growths than those who withdrew it in less than six minutes.

The study did not have a conclusive answer as to exactly long physicians should spend withdrawing the tube. Other experts say to keep it in the range of six to ten minutes.

I know this is the last thing you want to say to your physician-- "Can you keep that up there a bit longer please?', but it might just save your life.

The earlier a cancer is detected, the greater the chances for cancer survival. One of the problems in surviving colon cancer is that people are reluctant to undergo colonoscopies, and therefore, colon cancer is not always detected in its earliest stages before symptoms develop.

Mount Sinai School of Medicine and EXACT Sciences Corporation are publishing study findings that show a DNA stool test can accurately predict colorectal cancer 88 percent of the time, regardless of where in the colon the cancer is located.

"This study confirms that stool-based DNA technologies can achieve high sensitivities for detecting colorectal cancer," stated Steven Itzkowitz, M.D., principal investigator and Professor and Associate Director of Gastroenterology at Mount Sinai School of Medicine. "For those individuals who are unwilling or unable to undergo colonoscopy, stool DNA testing offers a valuable and patient-friendly screening option. These results also underscore that as new markers and technologies are developed and validated, they can readily be incorporated into existing stool DNA tests to improve cancer detection and, ultimately, patient outcomes."

According to statistics, colorectal cancer is the second leading cause of cancer deaths in the U.S. and more than half of the over 80 million people over the age of 50 have never been screened. I agree with the researchers who suggest that it is time to develop new non-invasive technologies for colorectal screening.

According to the findings of a study done by researchers from Indiana University, five years after a colonoscopy which detected no precancerous growths or polyps, the risk of having a potential cancer is very low.

The results of the study were presented at the 71st Annual Scientific meeting of the American College of Gastroenterology (ACG). The study also found that the risk of advanced adenomas, a type of colon polyp more likely to become cancerous, while still low, was higher in men than in women. These findings suggest that a longer follow up screening may be safe.

Among the 2,436 patients in the screening program, 1,256 returned for screening after five years. No cancers were found in any of the patients. ACG recommends that for average risk individuals, colorectal cancer screening tests should begin at age fifty. For high risk individuals however, screening colonoscopy should begin earlier and be performed more frequently. For both average and high risk individuals, all potential pre-cancerous polyps must be removed.

Virtual colonoscopies, using a three-dimensional computed tomography colonography, is a non-invasive procedure for colorectal cancer screening and as accurate as the traditional very invasive procedure, according to the conclusion of a study conducted by University of Wisconsin researchers.

"Virtual colonoscopy produces precise and detailed 3-D fly-through images of the entire colon's interior without having to insert a scope -- there is essentially no risk of bleeding or of perforating the colon," stated Dr. Perry J. Pickhardt.

Virtual colonoscopies take an estimated ten minutes to perform, as the patient passes through a scanning machine. The researchers suggest that this new way of testing might bring more reluctant patients -- who avoid the invasive and uncomfortable colonoscopies available now -- in to be screened. Oh, ya think? Virtual colonoscopy is the screening test I would choose. Who wouldn't? Of course, if polyps or cancers are found, they must be removed by optical colonoscopy.

I cannot imagine anyone who would forego a colonoscopy if they can be offered the virtual colonoscopy screening. I certainly hope this becomes a standard in every part of the country.

Why do we shy away from the colonoscopy? It just seems like such a fun experience! Well, I'm sure it will never be that but music seems to help with anxiety and the need for higher doses of medication before the procedure. There is a 90% cure rate when colon cancer is caught in its earliest stages.

We know that music can soothe us, lift our spirits, make us sad, give us energy and many other emotional responses. Its seems like a given that it would help patients better tolerate scans and procedures. If the tests are more anxiety free then more of us might actually make those appointments we keep putting off.

A study done by the doctors at Temple University in Philadelphia showed that music played during a colonoscopy procedure made some patients able to relax enough to require less sedation, without sacrificing comfort.

According to Benjamin Krevsky, M.D., M.P.H., "Over all, colonoscopies are very, very safe and while the risk of sedatives are relatively small, in general, less medication is always better. Offering music has no down side, it may prove beneficial, and patients appear to be satisfied with the procedure."

I myself am guilty of putting off the colonoscopy. Since I was diagnosed with breast cancer my oncologist has been recommending the procedure. ok, so ..

What kind of music goes with a colonoscopy? hmmmm...

Katie Couric spent her summer traveling the country visiting with future CBS news fans and raising money for cancer awareness. Couric, whose husband Jay Monahan died of colon cancer in 1998 at the age of 42, has become a prominent spokesperson for colon cancer awareness. She underwent a colonoscopy on-air in March 2000 and inspired many others to get checked. In October 2005, in honor of Breast Cancer Awareness Month, Couric broadcast her own mammogram on the Today Show in hopes of motivating women everywhere to get schedule their own mammograms. Her influence on both cancer fronts -- known as the Couric Effect -- demonstrates the fact that one powerful person can draw much attention to important causes. And perhaps her influence -- soon to arrive on television screens everywhere -- will continue as she takes the driver's seat on the CBS Evening News beginning September 5 at 6:30 PM.

On her second day of work in her new job, Couric will interview President Bush at the White House as part of a primetime special. Other story plans include digging deeper into the stories of the day and answering questions viewers might have on all topics. Hopefully, cancer issues will continue to take priority in Couric's life so that we all may benefit from her advocacy.
