Is anorectal cancer contagious?

Now we all know that some diseases can be transmitted to each other, such as hepatitis B, tuberculosis, AIDS, etc. In fact, there are many diseases around us that we can't imagine that can also be transmitted, but we don't know much about them, and always think that everything is very safe, but it is not. Now let's take a look at whether diseases such as anorectal cancer are contagious.

According to relevant scientific reports, people who live together for a long time will be infected with many diseases at the same time because of the same eating habits and similar lifestyles. Recently, Ms. Leah from the UK divorced. Her reason was that her husband, Richard, had rectal cancer. Leah was not ignorant of the principle of couples in distress, but she believed that Richard liked red meat, alcohol and spicy food, had a bad temper, insisted on smoking, and became obese year by year. Such a lifestyle would be transmitted to her and her children. In response to this, Guancheng experts proposed that rectal cancer can be transmitted between husband and wife. The following is a brief introduction to the causes of rectal cancer:
Patients with rectal cancer have a typical acidic constitution, and the origin of acidic constitution is precisely excessive intake of acidic foods or incorrect lifestyle habits. Rectal cancer cells are typical acid-loving cells. The formation of an acidic constitution is the cancerization of normal cells, which is the doubling of the growth of already formed cancer cells. Epidemiological studies have shown that the occurrence of rectal cancer is significantly related to economic conditions and dietary structure. The incidence rate is significantly higher in economically developed areas, regions and groups with a high proportion of animal fat and protein in the diet and low fiber content. The exact mechanism of the relationship between dietary structure and the occurrence of rectal cancer is not yet fully understood. It is generally believed that it may be related to factors such as the metabolites of animal fat, bacterial decomposition products, and slowed intestinal peristalsis and increased intestinal toxin absorption due to a low-fiber diet.
So we should not always think that if we feel nothing is wrong with something, then it will really be fine. But at the same time, we should also maintain a healthy mind and learn more about each disease. It always does no harm to know more.
