Every place I have lived people claimed some kind of Cancer epidemic.
Cancer is a disease of the aged, and the common element of the cells is multiploidy or multiples of the normal genome compliment.
Cancer is on the decline inspite of the EPA claim that they find carcinogens everywhere.

From the National Cancer Institute’s article
For the past two decades, both the incidence and mortality of cancer in America has been in decline. Earlier, in the 1990s, the rate of decline was quite rapid, all things considered, largely due to rather astounding reductions in smoking that followed the first Surgeon General’s report in 1964 (cancers from smoking both develop over at least a decade or more, and decline with a similar lag period after quitting).
A new report published in the journal Cancer documents the continuation of this salutary trend. However, the rate of reduction in both death and incidence (new cancers) has slowed quite a bit, again owing largely to the slower fall in smoking rates over the past 10 years or so.
From 2001 through 2010, death rates for all cancers combined decreased by 1.8 percent a year among men and by 1.4 percent a year among women, according to the joint report from some of the nation’s top cancer institutions (including the CDC, the NCI and the American Cancer Society).
“The four major cancers — lung, colorectal, breast and prostate — represent over two-thirds of the decline,” study author Brenda Edwards, a senior advisor for cancer surveillance at the U.S. National Cancer Institute, told HealthDay News.
Let’s see, EPA says cancer is a big problem, and air as well as every other thing they have identified as a carcinogen in their silly rat tests is raising havoc int he population, but the NCI says that cancer is in decline.
Maybe we should reconsider the EPA effort to take us back to those good old days?
three day stool test for blood is a less invasive screen, the GI guys would prefer that to nothing.
colonoscopies are not without some risk, virtual colonoscopies by radiology have become the rage. multiple sensor CT is an amazing technology, you should see some of the computer images that can be created.
the other day we had a guy with a jaw fracture and the computer made his skull a 3 D image to show the fractures– most big jaw fractures have two fracture sites because it’s a ring, and the pictures of the face and skull sans tissue, just bone,were really cool and easy to interpret.
radiologists have shown me vascular abdominal CTs that are incredeble, and CT Angiography is a marvel and now the way to look at blood vessels in your noggin.

There are alternatives to colonoscopy for detection of polyps and cancers. If you have a family history of cancer, that might make a colonoscopy more advised.
This page: http://www.cdc.gov/cancer/colorectal/basic_info/screening/#1 seems to indicate the CDC believes screening does save lives due to early detection. As with all medical procedures, there is a risk/reward ratio. You need to discuss this fully with your physician to how high a risk you have and what procedures might work for you.
looked over the NCI report.
Have no idea about why the incidence of colon cancer is declining but it sure is.
As for survivals we can attribute that to better and earlier treatment, I do believe..
In addition to slower declines in smoking, that might be another large factor slowing the decline.
The population is aging, at least more elderly from the baby boomers. It’s surprising the cancer rate didn’t follow the age increase.
Federal research agencies became official promoters of government propaganda after theSecond World War.
These actions confirm that George Orwell was correct in the predictions made when he started to write “Nineteen Eighty-four” in 1946, the same year that textbooks of
1. Astronomy started teaching that the Sun is a giant ball of Hydrogen, and
2. Nuclear physics and chemistry started replacing Lord Francis W. Aston’s valid “nuclear packing fraction” with von Weizsacker’s invalid “nuclear binding energy”.
Both deceptions became part of the foundation of post-normal science, they are promoted by federal research agencies like NASA and DOE, and are taught in classrooms around the globe today.

I asked because I have never had a colonoscopy (58 year old). I had one scheduled. The drink they gave me did not work and made me very sick. Now they want to try it again with some stuff that is even more likely to make me sick. Then I here from the CDC that there is no proof that it works!
this is one place were vigilance and intervention and surgical treatment can have an impact.
not on incidence but on survival.
I promise I will look at the numbers and revisit that issue.

Why is colorectal cancer on the decline? The CDC says that there has not been a study establishing a decline in mortality due to colonoscopies. So what else is causing the decline? Diet?
