Colorectal is the second most common cancer in China, how high is its mortality rate?

When it comes to cancer, it's a disease that scares people. Once you have cancer, not only does it cost a lot of money, but there is no guarantee that it will be completely **. About this cancer of the colorectum,Colorectal mortality is also high, and if not well cared for, it may increase.

1. Causes of colorectal disease.

The causes of colorectal disease are closely related to genetic factors, and if one of the parents has colorectal disease, then the chance of having a child with colorectal disease is very high. According to statistics, genetic factors may play an important role in about 20% of colorectal cancer patients. In addition to genetic factors, there is also a certain relationship with external factors.

For example, it has a certain relationship with our dietary habits, if we regularly consume high animal protein, high fat is a factor in the high incidence of colorectal cancer. If there is chronic ulcerative colitis, this condition can also induce colon cancer, which is at least about 5 to 10 times more likely to become cancerous than the normal population.

2. How to prevent colorectal cancer?

Nowadays, more and more people are suffering from colorectal cancer, so it is important to learn how to prevent colorectal cancer. If you want to prevent colorectal cancer, you should develop a good diet and lifestyle habits, and eat a low-fat diet with a high-fiber diet as the main one. Then, don't smoke or drink.

At ordinary times, we should also do some exercise appropriately, exercise can enhance our body's immunity, and can avoid a lot of cancer. <>

In addition, regular check-ups are one of the important ways to prevent any cancer, cancer does not have any symptoms in the early stage, so only when you go for a check-up will you find out the problem, and detect and treat early cancer or precancerous lesions. If there are first-degree relatives with colorectal cancer in the family history, this must be paid attention to, and the colonoscopy must be checked regularly, because colorectal cancer and genetic factors are very related. The above is just my personal opinion.

It is very high and has a relatively strong lethality, so the mortality rate is very high, and this mortality rate allows us to better understand the horror of this matter.

I think it already has a high mortality rate, ranking second among common cancers.

The mortality rate is relatively high, because it is not difficult to treat, and most of the cases are found at an advanced stage, so the mortality rate is very high.

Colorectal cancer is one of the most common malignant tumors in the world, with the world's highest incidence and mortality, and the incidence and mortality of malignant tumors of the digestive system. In recent years, the incidence of colorectal cancer in China has been on the rise, and it has become a malignant tumor of the digestive system in China. According to relevant data, the 5-year survival rate of colorectal cancer in China is much lower than that of the United States, Japan and South Korea, and more than 85% of colorectal cancer cases have progressed once they are detected.

Why are most colorectal cancers detected late?

<> advanced colorectal cancer can present with gastrointestinal symptoms such as changes in bowel habits, constipation, diarrhea, blood in the stool, abdominal pain, bloating, and intestinal obstruction, as well as systemic manifestations such as anemia, fatigue, fatigue, and fever. However, early-stage colorectal cancer may be asymptomatic. These symptoms can be easily confused with those of hemorrhoids and other diseases and can easily be seen as common by patients.

Therefore, once colon cancer is detected, it is often in the middle and advanced stages, and the best chance is missed.

For colorectal cancer, early screening is the best way to prevent it, and the rate of early detection and early detection is relatively high! Even after a combination of surgery, radiotherapy, chemotherapy and targeting**, the 5-year survival rate for patients with advanced colorectal cancer is significantly less than 40%. In contrast, the 5-year survival rate after early colorectal cancer** is more than 95% and can even be completely**.

However, the current diagnosis rate of early colorectal cancer in China is less than 10%, which is related to the lack of awareness of early screening among Chinese residents.

Colorectal cancer screening should only be considered if there are particularly uncomfortable symptoms. Early detection of colorectal cancer is difficult because people give up screening due to lack of experience such as colonoscopy. It is important to know that colorectal cancer rates are generally higher in developed countries than in developing countries due to obesity and poor diet.

However, despite the high incidence of colorectal cancer in the United States and some European and American countries, mortality has continued to decline over the past 25 years due to widespread screening, with a decline of 47% in men and 44% in women.

The mortality rate of colorectal cancer in China is very high, ranking second in the mortality rate; Because the symptoms of bowel cancer are not very serious at the beginning, many people do not pay attention to it, so they do not go for examination, and wait for the symptoms to be serious before going for examination, which is already at an advanced stage at this time.

Colorectal cancer is asymptomatic in the early stage and is good at camouflage.

In the later stage of colorectal cancer, it can show changes in bowel habits, gastrointestinal symptoms such as constipation, diarrhea, blood in the stool, abdominal pain, abdominal distension, and intestinal obstruction, as well as systemic manifestations such as anemia, fatigue, fatigue, and fever. However, early-stage colorectal cancer may have no obvious symptoms.

These symptoms are easily confused with the symptoms of other diseases such as hemorrhoids, and are easily treated as ordinary diseases by patients, so once intestinal cancer is found, it is often in the middle and advanced stages, and the best opportunity is missed.

The Chinese people do not have a strong awareness of screening.

For colorectal cancer, early screening is the best way to prevent it, and the rate of early detection, early **, ** is relatively high! For advanced colorectal cancer, the 5-year survival rate of patients with advanced colorectal cancer is still significantly lower than 40% even after surgery, chemoradiotherapy, targeted treatment, etc.**; Conversely, the 5-year survival rate after early colorectal cancer** can exceed 95% or even completely**.

However, at this stage, the diagnosis rate of early colorectal cancer in China is less than 10%, which is related to the fact that Chinese residents do not have a strong awareness of early screening.

The mortality rate is very high, more than 50%. Because the early symptoms of colon cancer are not obvious, patients may be mistaken for other gastrointestinal diseases, thus delaying**.

In 2020, WHO data showed that the incidence of colorectal cancer in China has surpassed that of gastric cancer, ranking second. And colorectal cancer also has the second highest mortality rate globally, after lung cancer.

Cancer has a certain "insidiousness", and bowel cancer is no exception. For patients with bowel cancer, it is diagnosed at an advanced stage, and it is often not possible to detect abnormal signals in the body at an early stage. In fact, the arrival of bowel cancer did not come quietly.

There are some inconspicuous abnormal symptoms that are likely to be overlooked by you.

First of all, frequent farting, fart odor may be an abnormality in the intestines. After the appearance of bowel cancer, it may cause intestinal blockage, affecting the digestion and absorption of food in the intestines. When food residues are retained in the intestines, they will continue to react with intestinal bacteria and produce more gas, that is, fart.

The smell of farting is also indicative of gut health. On the premise of not eating high-protein, high-starch foods, the smell of farting is very smelly, there is a smell of ammonia, and the fishy smell of fish should also be alert to bowel cancer.

Secondly, the state of bowel movements may also indicate bowel cancer. When cancer cells appear in the intestines, it can lead to damage to the intestinal mucosa, erosion, bleeding, and blood mixing in food residues to form stool. At this time, the stool may be dark red or even pus-like.

Also, bowel habits can be easily overlooked. Everyone has their own bowel habits. Some people have a bowel movement once a day, while others only have a bowel movement every 2-3 days.

But from a scientific point of view, 2-3 bowel movements per week and 2-3 bowel movements per day, as long as a certain pattern is formed, there is nothing wrong with it. But when you are used to having 2-3 bowel movements a week2, and suddenly it changes to 2-3 times a day, it is not normal.

Affected by tumors in the intestine, it can cause changes in people's bowel habits. Bowel movements will become more and more irregular, and bowel movements will not be clean, not bowel movements for a long time, and many times a day. If these abnormalities are detected, it is best to screen for bowel cancer in time.

Colorectal cancer is a type of tumor that is at an advanced stage once it is detected. People's unreasonable eating habits and work and rest habits may induce colorectal cancer, so we must be vigilant.

There are a lot of diseases in this disease, and they are related to people's daily diet, which may be ignored by many people.

Colorectal cancer is a malignant tumor that occurs in the rectum and other areas. Many people think that colorectal cancer has nothing to do with them, but this idea is wrong, and the incidence of colorectal cancer has always been very high. The incidence of colorectal cancer is concentrated in the middle-aged and elderly population, and the incidence of colorectal cancer in men is higher than that in women.

Lifestyle habits: Many people have bad habits such as irregular diet and irregular life and rest in their lives, so they have a certain malignant impact on the large intestine and lead to colorectal cancer. Diet is not balanced:

Many people have a diverse diet, mostly based on a Western dietary pattern, mainly high-protein and high-fat foods, and less fruity and vegetable intake. It increases resistance to bowel peristalsis and is easy to induce colorectal cancer. Genetic factors:

Some people have a history of colorectal cancer in their families, and their offspring may also have the potential to induce colorectal cancer. Environmental factors: Being in a stressful environment can also induce colorectal cancer.

Personal mentality: Long-term depression will lead to changes in body functions and can also induce colorectal cancer.

The symptoms are: pulling blood, people suffering from rectal cancer, the early symptoms are blood in the stool, and it often occurs, not once or twice, after this situation occurs, it is necessary to pay full attention to it, seek medical attention in time, see the situation, and ** early.

The main symptoms of colorectal cancer are abdominal pain, blood in the stool, anemia, weight loss, and patients may also experience symptoms such as obstruction, cramping pain, and changes in bowel habits.

Patients with colorectal cancer may also have symptoms such as pernicious anemia, weight loss, fatigue, nausea, and vomiting when it is severe. However, symptoms vary from patient to patient.

Changes in the habits of the intestines. For example, if you suddenly start having diarrhea or constipation, or if your stools are getting thinner, it may be caused by a tumor that narrows your intestines. If the condition is more than four weeks, you should go to the hospital for a check-up.

Rectal bleeding or blood in the stool. It does not mean that blood in the stool is necessarily bowel cancer, and the vast majority of bleeding cases are not related to tumors. For example, if the blood is black, it may be bleeding from the stomach.

If the blood is bright red, it is most likely bleeding caused by hemorrhoids. In fact, bleeding caused by colorectal cancer is usually chronic, the amount of blood is usually small, and it is not easy to see in the stool, which may cause anemia symptoms over time.

Persistent abdominal discomfort, such as cramping, gas, or pain.

It always feels like the intestines are not completely empty.

Weakness, fatigue, unexplained weight loss.
