Who is more likely to be targeted by colorectal cancer?

Pay attention to intestinal health and prevent colorectal cancer

Colorectal cancer is a tumor that occurs in the ascending colon, transverse colon, descending colon, sigmoid colon, and rectum

The prognosis of colorectal cancer is closely related to early diagnosis.

In fact, the occurrence and development of colorectal cancer is a very long process, most of which follow the development process of "adenoma-carcinoma".

Who is more likely to be targeted by colorectal cancer?

Male: Male morbidity and mortality are higher than females, male morbidity is 1.

Age: The risk of cancer increases with age, and the risk gradually increases from the age of 40;

"Wealth disease": its incidence is higher in cities than in rural areas, which is related to economic development;

Genetic family history: relatives of patients with colorectal cancer are at higher risk of the disease;

People with unhealthy life>

Intestinal symptoms in people: such as abdominal pain, bloating, diarrhea, constipation, weight loss and so on

What are the symptoms of colorectal cancer?

Early stage: No specific performance, is a hidden killer

Progression:

1.

2.

3.

4.

Screening start and end age: It is recommended to receive colorectal cancer risk assessment from the age of 40.

Those over the age of 40 who have any of the following manifestations are at high risk:

First-degree relatives have a history of colorectal cancer (including family history of non-hereditary colorectal cancer and family history of hereditary colorectal cancer);

I have a history of cancer or a history of intestinal adenomas or polyps;

The stool occult blood test was positive

Those who have more than two of the following: mucus blood in the stool, chronic diarrhea, chronic constipation, history of chronic appendicitis, history of mental trauma

Colorectal cancer screening methods

1.

Stool occult blood test is the fecal occult blood test we usually use more frequently.

2.

Digital anus examination is a method in which the doctor inserts the index finger into the patient's anus to check for diseases.
It can roughly determine whether there is any disease in the rectum and anus 7-10cm from the anal edge
.
Rectal cancer in China is mostly low rectal cancer, so digital anal examination is one of the commonly used screening methods for rectal cancer
.

3.
Colonoscopy

Colonoscopy plays a unique and irreplaceable role in colorectal cancer screening.
Colonoscopy biopsy is the gold standard for the diagnosis of colorectal cancer, which means that it is the most accurate method to screen for colorectal cancer and precancerous lesions
.
However, because the examination is invasive and requires sufficient bowel preparation and necessary dietary restrictions, there are certain pains and complications during the examination.
At the same time, the lack of colonoscopy equipment and doctors in China often leads to long appointment cycles, so the popular colonoscopy The screening rate is not high
.

4.
SDC2 gene methylation detection

SDC2 gene methylation test is a new type of colorectal cancer screening method, which is suitable for high-risk people who are unsuitable or unwilling or fearful of colonoscopy due to various reasons such as age and disease
.
The simple understanding of the principle is to do a genetic test on the stool to determine whether there is a genetic mutation that causes colorectal cancer
.
It can be detected with only a little feces, and sample collection can be done at home.
It is non-invasive, painless, risk-free, convenient, and highly accurate, especially for early colorectal cancer with a sensitivity of 86.
71%
.
This inspection also implements a model of preliminary screening and then precise screening that is in line with China's national conditions: when the test result is negative, it indicates that no gene mutations related to colorectal cancer have been found, and regular follow-ups are enough; when the result is positive At this time, it indicates that there are gene mutations related to colorectal cancer, that is, there may be polyps, adenomas, precancerous lesions, colorectal cancer, etc.
in the intestine.
At this time, the colonoscopy can be further improved (warm reminder: people with positive test results can Reimbursement of colonoscopy expenses)
.

How to prevent colorectal cancer?

For intestinal health, in addition to early screening, daily health care cannot be ignored:

1.
Follow the healthy diet guidelines, control energy intake, especially the intake of red meat such as pigs, cattle, and sheep, and increase the intake of dietary fiber, whole grains, and dairy products;

2.
To quit smoking and limit alcohol;

3.
Exercise regularly, reduce sitting and move less;

4.
Develop good bowel habits;

5.
Maintain a suitable weight;

6.
Participate in activities that are beneficial to mental health and relieve stress;

7.
Avoid drug abuse and unnecessary drugs;

8.
Healthy people should be screened for early diagnosis and treatment:

Occult blood examination: once a year;

Digital anus examination: once a year;

SDC2 gene methylation detection: once every 1-3 years;

Colonoscopy: once every 3-5 years
