Are patients contagious before bowel cancer surgery?

As people's living conditions improve, their living standards are getting better and better, but some people do not pay attention to their health due to busy work or other reasons, which leads to colorectal cancer. Colorectal cancer is a malignant tumor among digestive tract diseases. Many people are curious about whether colorectal cancer is contagious. The following editor will show you the relevant knowledge about colorectal cancer, and you will understand.

Colorectal cancer occurs mostly in people aged 40-50, with the median age being around 45. People under 40 account for about 1/3 of all cases, and people under 30 account for about 10%. The age of onset of colorectal cancer in my country is 10-15 years earlier than in foreign countries, and people under 30 account for 11-13% of cases. This is a major feature of colorectal cancer in my country. Like other malignant tumors, the cause of colorectal cancer is not yet clear, and may be related to the following factors.

1. Environmental factors: Among various environmental factors, diet is the most important. The incidence of colorectal cancer is positively correlated with the high fat consumption in food. In addition, it may also be related to the lack of trace elements and changes in living habits.

2. Genetic factors: There have been reports of "familial clustering of colorectal cancer" both at home and abroad. The rate of death from colorectal cancer in patients with family clustering of colorectal cancer is significantly higher than that of the general population.

3. Colon adenoma: The incidence of colon adenoma is quite similar to that of colon cancer. According to statistics, the incidence of colon cancer in patients with one adenoma is 5 times higher than that in patients without adenoma, and the incidence of colon cancer in patients with multiple adenomas is 1 times higher than that in patients with a single adenoma.

4. Chronic colon inflammation: The prevalence of colon cancer is positively correlated with the prevalence of schistosomiasis. It is generally believed that due to schistosomiasis, inflammatory changes in the intestines may lead to cancer in some cases. Other chronic inflammations of the intestines may also lead to cancer, such as ulcerative colitis, which has a 3-5% chance of cancer.

For the treatment of colorectal cancer, we need to know more about the common knowledge of colorectal cancer. Now that we know the cause of colorectal cancer, in order to better treat colorectal cancer, we also need to know more about the early symptoms of colorectal cancer and try to detect the disease as soon as possible. So what are the early symptoms of colorectal cancer?

Main symptoms: changes in bowel habits and blood in stool. Most of them are manifested by an increase in the frequency of bowel movements, unformed or loose stools, and mild abdominal pain before defecation; blood in stool is an important symptom, manifested as bright red or dark red stools, often accompanied by mucus. Abdominal pain is also an early symptom, the pain is mostly in the middle and lower abdomen, the degree is not severe, and it is often ignored as dull pain. As for abdominal distension, abdominal mass, anemia and intestinal obstruction, they are late symptoms of colorectal cancer.

In summary, I believe everyone should understand the answer to whether colorectal cancer is contagious. Everyone must pay attention to the early symptoms of colorectal cancer. Once discovered, do not be lucky and go to a regular hospital for relevant examinations to avoid the occurrence or deterioration of colorectal cancer.
