How can colorectal cancer be screened early? What should be done for early screening of rectal cance

Rectal cancer screening, generally speaking, there will be no symptoms in the early stage of rectal cancer, once the patient has clinical manifestations and symptoms, it is often at an advanced stage, and the chance of getting the best at this time is relatively low. How to detect early rectal cancer and cancer screening: 1. Check whether there is hidden blood in the stool that cannot be seen by the naked eye, if possible, further examination, the cause of occult blood may be rectal cancer or colon cancer.

2. The finger examination of the rectum is called the finger anus, and the fingers are touched to see if there is a lump in the rectum. 3. Colonoscopy, CT, color ultrasound, etc. 4. Of course, a very important part of rectal cancer screening is blood examination.

High-risk groups are many times more likely to develop colorectal cancer than the general population, and fecal occult blood testing or colonoscopy should be added to the annual physical examination.

If there is a change in stool quality and habits, abdominal pain, blood in the stool, a mass in the intestine or abdomen, acute and chronic intestinal obstruction, intestinal perforation, anemia, fatigue, emaciation and low-grade fever, etc., go to the hospital in time for digital anorectal examination, colonoscopy, CT and biopsy.

The most important screening for early colorectal cancer is regular colonoscopy and fecal occult blood, and the symptoms are basically absent or very atypical in the early stage.

Usually you should develop the habit of doing physical examinations, conduct early screening through physical examinations, and be able to understand the condition of the body as soon as possible, and be able to make certain measures to respect the ants.

Be sure to go to the hospital in time to receive **, and then you should also take corresponding precautions, and you should have a comprehensive examination.

In order to detect rectal cancer at an early stage, regular stool check-ups and colonoscopy should be performed, and the interval between examinations should be shortened if there is a history of cancer in the family.

Rectal cancer is one of the major malignancies today. Screening not only reduces the risk of disease, but also helps diagnose and ** in the early cavity stage. The prognosis of rectal cancer is closely related to early diagnosis, most early-stage colon cancers can be **, with a 5-year survival rate of up to 90%, while the 5-year survival rate of advanced rectal cancer is less than 10%.

The main screening methods are fecal occult blood test and gold standard colonoscopy.

People with a family history of cancer, such as breast cancer, liver cancer, and stomach cancer, are at high risk of cancer. Digestive tumors, such as colorectal cancer, may be associated with similar dietary habits within families. People who have been exposed to carcinogens for a long time, such as long-term smoking, drinking, staying up late, eating barbecue and pickled foods, or being exposed to formaldehyde, benzene, and radioactive substances are also at high risk of cancer.

For the above people, they should pay more attention to their own symptoms, and screening is even more important.

If your parent, sibling or child has been diagnosed with colorectal cancer, get screened earlier and more often. In the past, we recommended screening at age 50, but for some people it is too late. We want to encourage more high-risk people to get screened, regardless of their age group.

It is recommended that if you have an immediate family member with a history of colorectal cancer, then you should have a colonoscopy screening between the ages of 40-50 or ten years before the first diagnosis of colorectal cancer in your immediate family. For example, if a parent is diagnosed with colorectal cancer at age 45, you should start screening at age 35. "If you have a family history of colorectal cancer in a first-degree relative, your risk of developing the disease doubles.

Colorectal cancer is a type of cancer that can be screened out, and through screening, we can improve the prognosis. Similar screening recommendations apply to people with an immediate family member with a history of precancerous hail grinding (which can develop into cancer without **). However, if a second-degree relative, such as a grandparent or uncle, aunt, or aunt, has a history of colorectal cancer, then it is recommended that the screening age be the same as that of the general risk group, starting at age 50.

But start screening high-risk people at an earlier age, even if they're in their 20s or 30s. This shift also requires doctors to ask about a family history of colorectal cancer to ensure that as many people as possible are screened.

The first point is that if the intestines are particularly painful, it is likely to be a manifestation of colon cancer, the second point is that if you feel that the stomach is very dirty and uncomfortable, you must go to the hospital for examination in this case, and the third point is that you feel that the intestines always want to defecate and it is very unsmooth, in this case it may also be a manifestation of rectal cancer.

At present, there is no special method for early detection of colorectal cancer, but if we can be vigilant, pay attention to the "ten warning signs" of colorectal cancer in the early stage, and carry out "one finger and three examinations" in time, colorectal cancer can be detected earlier.

Be sure to have a physical examination every year, do colonoscopy, when you find that your stomach is swollen and painful, and your stool is bloody, then you should go to the hospital in time, otherwise the consequences are really serious.

I have to go to the hospital every year for regular check-ups, and if I have pain, I should ask the doctor in time so that cancer can be detected.

On your own side, you must pay close attention to the shape and color of your stool every day, as well as the frequency and difficulty of bowel movements. Once there is a significant change in these four aspects, it is necessary to be alert to rectal cancer. In addition, rectal cancer can be detected early through regular medical checkups.
