Is stomach cancer contagious if it spreads to the lungs in the late stage?

Gastric cancer will have a certain impact and harm on the health and life of patients. Nowadays, people live at a fast pace, which leads to many friends not being able to eat normally, which leads to the occurrence of gastric diseases. In severe cases, gastric cancer occurs. Then, if gastric cancer spreads to the lungs in the late stage, will it be contagious?

Gastric cancer is one of the most common malignant tumors of the digestive system. Gastric cancer can occur at any age, but the general trend is that the incidence rate increases with age. Gastric cancer in young people is often more malignant than in middle-aged and elderly patients, and should be given high attention. Since gastric cancer is extremely common and harmful in my country, relevant studies believe that its cause is related to eating habits, genetic factors, stomach diseases, etc.

Is gastric cancer contagious if it spreads to the lungs in the late stage? Professional doctors point out that many clinical studies have shown that cancer is not contagious, but there are different views on gastric cancer in clinical practice. On the one hand, it is believed that gastric cancer is not contagious. The simplest reason is that tumors are not infectious. They cannot introduce cancer-causing genes into other people's bodies through any means to cause tumors. Even if tumor cells are transplanted into other people's bodies, they are difficult to survive because of the existence of rejection reactions.

Although it is currently believed that the occurrence of certain cancers is related to certain viruses, such as cervical cancer, nasopharyngeal cancer, and leukemia, it has not yet been confirmed that infection with certain viruses will definitely lead to certain cancers. On the other hand, it is believed that gastric cancer is a contagious disease. Because Helicobacter pylori can cause gastritis and peptic ulcers, this oral bacteria has turned gastric cancer into a contagious disease.

According to relevant data, the risk of gastric cancer in people infected with Helicobacter pylori is 2.7 times that of uninfected people. In addition, eating together and not paying attention to dietary hygiene and regularity will increase the chance of infection with this type of bacteria, leading to a high incidence of gastric cancer.

Is advanced gastric cancer contagious?

1. Internal factors: mental and neurological factors, endocrine imbalance; genetic factors; immune deficiency

2. External factors: chemical carcinogens; physical carcinogens. It is now known that most cancers are caused by carcinogens in the environment, and chemical and physical carcinogens are not contagious. The most suspicious are biological carcinogens. Mycotoxins are known to be carcinogenic, but mold only contaminates food and then causes cancer in people through the toxins it produces. The toxins themselves are not contagious. The problem of viruses may be a little more complicated.

3. Cancers suspected to be caused by viruses include the following: ① leukemia, liposarcoma ② breast cancer, ③ nasopharyngeal carcinoma, cervical cancer, African childhood lymphoma. Serological tests have proven that they are related to EB virus, herpes-like virus, herpes simplex virus, ⑿ tube "Ju Xie Qiu" liver cancer, and hepatitis B virus. Although viral antigens or anti-viral antibodies can be found in patients, there is no conclusive evidence to show that cancer is caused by viruses.

Through the introduction above, we know that gastric cancer is not contagious. No matter how gastric cancer occurs, it will bring certain risks to the life and health of patients. Therefore, we must pay attention to the occurrence of gastric cancer in our daily life and actively treat it.
