Colorectal cancer there are many, but we usually refer to the higher incidence of colon and rectal cancer.
Currently, the incidence of colorectal cancer is also rising, and even has evolved into the most commonly diagnosed cancer in Singapore. But if early detection, cancer is the most easily curable cancer. Benign colorectal polyps by general evolved. These grain-like polyps can grow to the size of people's fist. In these benign polyps removed before they become malignant, the best way to prevent colorectal cancer, the survival rate of up to 90%.
However, the vast majority of patients with colorectal cancer symptoms in the surge of 2 to 3 months before going to hospital examination. By then, the cancer had spread. Once the lead to complications such as intestinal obstruction or intestinal perforation, the patient's survival will be greatly reduced. Unfortunately, 40% of hospital patients with colorectal cancer for the first time to check already ill, and this is because most people do not attach importance to the cause and prevention of colorectal cancer due.
There are many causes of cancer, mainly in the following two points:
Cause a cancer, long-term consumption of high fat, high protein food.
These foods stay longer in the large intestine, easy to form carcinogens. Therefore, doctors suggest that you reduce the intake of animal fat, eat more vegetables and fruit, and fiber, starch rich foods. Such as potatoes, cereals, rice, pasta and so on.
Also, do not forgetful to maintain body weight, and often sports.
Second cause cancer, genetic.
25% of colorectal cancer in a family history of colorectal cancer; the vast majority of members of some families prone polyps, if left unchecked, then the incidence of colorectal cancer is also 25%. People over the age of 50 should take all measures to prevent colon cancer. Because, over the age of 60 have a 50% president of colorectal polyps.
And we do not know what sizes of polyps will develop into cancer. Therefore, we have to schedule inspections.
Two main types of colon cancer screening method:
First, a variety of colonoscopy.
Second, fecal occult blood stool test experiment.
Colonoscopy is a fine camera with a small catheter inserted into the patient's colon through the anus, the correct rate is relatively high. But the patients are suffering, but in degrees higher.
Stool tests will not have any pain of course, nothing more than the correct rate is not high, only about 60%.
Colorectal cancer symptoms in view of the above points, we at least pay attention to:
First, your parents or brothers and sisters in direct support of these colon cancer is found, do you have to schedule colonoscopy.
Second, less than 50 years of age found that colorectal cancer is non-immediate support, you can allow doctors to decide whether to do colonoscopy.
Third, if the following symptoms for two weeks or more than two weeks, you have to go to hospital checked:
change in bowel habits, such as diarrhea or constipation often recently; stool with mucus; and previous match, stool form thinner.
often with bright red blood or dark red stool blood and mucus.
not excrete stool tenesmus always feel complete.
many parts of abdominal pain and sadness in the lower abdomen, varying degree of severity, mostly for pain, or pain.
along with fatigue and anemia are often unable to explain the sudden drop in weight.
