Can rectal cancer be transmitted through feces?

There are many people who fight cancer now, and they are very successful. Therefore, even if you have advanced colorectal cancer, you should not give up. You should find a professional hospital for treatment, insist on treatment, insist on taking anti-cancer drugs, and control the spread of cancer cells. Many people think that colorectal cancer is contagious, so can colorectal cancer be contagious through feces? Let's take a look at the following introduction.

Can colorectal cancer be transmitted through feces? Relevant experts have proposed that transmission must meet three conditions: source of infection, route of transmission and susceptible population, all three are indispensable. However, clinical data have shown that cancer patients themselves are not the source of infection, so colorectal cancer is not transmitted through feces.

In the early stage of colorectal cancer, there are no symptoms or the symptoms are not obvious, only discomfort, indigestion, occult blood in stool, etc. As the cancer develops, symptoms gradually appear, manifested as changes in bowel habits, abdominal pain, blood in stool, abdominal mass, intestinal obstruction, etc., with or without systemic symptoms such as anemia, fever and weight loss. Tumor metastasis and infiltration can cause changes in the affected organs. Colorectal cancer shows different clinical symptoms and signs due to different locations of occurrence.

The causes of colorectal cancer are as follows:

1. Environmental factors: Studies have shown that among various environmental factors, diet is the most important, and 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 lifestyle habits.

2. Genetic factors: There are reports of "family-based colorectal cancer" both at home and abroad. The number of blood relatives of colorectal cancer patients who died of the disease is significantly higher than that of the general population. Some colorectal adenomas, such as multiple familial adenomatosis, are autosomal dominant genetic diseases with a family prevalence rate of up to 50%. If not treated, there is a possibility of colorectal cancer after the age of 10. Recently, some scholars have studied the relationship between tumor suppressor genes and colorectal cancer and found that the susceptibility and pathogenesis of colorectal cancer are both related to genetic factors.
