Colon cancer, rectal cancer increase among generation X, generation Y
The disturbing information first came to attention with the launch of an American Cancer Society study published in the Journal of the National Cancer Institute. The studies found that the majority of colon and rectal cancers, nearly 90 percent, are still found in people 50 and older.
But the researchers also report that while colorectal cancer
rates have declined steadily among people born between 1890 and 1950, they have
risen dramatically with each generation since 1950, about 1 to 2 percent a year
for adults in the range. From 20 to 30 years old. .
That means a person born in 1990 would have twice the risk
of colon cancer and four times the risk of rectal cancer at the same age as if
they were born in 1950, according to researchers from the American Cancer
Society and the National Cancer Institute. Cancer, who helped fund the studies.
A 2020 report show that colorectal cancer is expected to
cause more than 50,000 deaths by 2020, including 3,640 deaths in people under
the age of 50.
When these cancers appear in young adults, they are usually
diagnosed at a much later stage. Doctors often mistake symptoms for something
else, like hemorrhoids, as rates of colorectal cancer in this age group used to
be rare.
Although colonoscopies, which check for precancerous growth
(polyps), are recommended for adults over the age of 50, there is no standard
recommendation for younger adults at this time, because, until now, there has
never been a real needs.
What are colorectal cancer?
Colorectal cancers is used to describe cancer that begins in
the colon or rectum, which are part of the large intestine. They are often
grouped together because they both share many similar characteristics.
Colorectal cancers generally begin with the growth of polyps
along the lining of the colon or rectum. That's what colonoscopies looks for.
Most polyps are benevolent, but some can ultimately turn into cancers.
According to the Americans Cancer Society, the wall of the
colon and rectums is made up of layers, and colorectal cancer begin in the innermost
layer, although it can grow outward. Once cancer cells are in the walls, they
can grow into blood vessels or lymph nodes, traveling out of the colon or
rectum and to the rest of the bodies.
The stage of a person's colorectal cancers depends on how
far the cancer cells have gotten into the wall and whether it has spread to
different parts of the body.
