When do HP bacteria cause stomach cancer?

The proportion of people with HP bacteria is now quite high. Many people who test positive for HP bacteria often think about the risk of cancer. How bad is this problem? When do HP bacteria cause cancer for humans?

It should be noted that HP bacteria are very contagious . In addition to the gastric mucosa, it also exists in saliva, plaque on the teeth and oral cavity of patients. Therefore, HP bacteria are mainly transmitted from person to person by sharing bowls, kissing directly, eating together .

HP bacteria are very contagious.

Associate Prof. Dr. Nguyen Duy Thang, Director of the Institute of Gastroenterology and Gastroenterology, said that children are at high risk of HP infection due to the mother's habits of rice and porridge.

HP bacteria also exist in human feces, so it can be spread through hands because after going to the toilet do not wash or through intermediate animals such as mice, cockroaches .

In addition, HP bacteria in the stomach can be infected during the implementation of gastroscopy operations in medical facilities because the test equipment is not cleaned.

Many people think it is harmful to have HP bacteria in their stomachs. Is it really like that? In fact, scientific studies show that in some cases, HP bacteria are not harmful . Without causing symptoms such as abdominal pain, flatulence, indigestion, vomiting . the presence of HP bacteria is like a symbiotic bacterium, sometimes with some good effects on the body .

For example, people with HP are less likely to have infections, especially intestinal infections, which are secreted by HP to inhibit other bacterial growth. In addition, symptoms of reflux or allergies such as pollen, pollen dust . will also be reduced if the presence of HP bacteria in the stomach is present.

Some roads spread HP bacteria from one person to another.

But some people worry that having HP bacteria in their stomachs will lead to cancer. However, according to Dr. Nguyen Duy Thang, HP bacteria is one of the causes of stomach cancer, not everyone with HP bacteria has stomach cancer.

According to the research of K hospital - the current leading hospital on cancer in Vietnam - there are 200 different types of HP, only some of them carry CagA gene with high virulence, increasing the risk of cancer. When infected with HP bacteria, patients can test HP bacteria belonging to the group of virulence carrying CagA gene. In fact, up to 80% of people over age 50 carry HP bacteria but not everyone develops cancer. Therefore, experts recommend that people should not be too worried and should go to reputable medical centers to test to see if they have HP infection and which strain to take appropriate treatment.

Only when HP bacteria appear clinical symptoms (abdominal pain, flatulence, dyspepsia, vomiting .), the treatment is important to reduce the risk of harm it causes. This is necessary to prevent complications such as gastrointestinal bleeding, gastric perforation and stomach cancer. Therefore, early detection and treatment of HP infection should be detected.

According to experts, if detected early, the cure rate is 50% ; It is difficult to cure when relapse without first treatment right away. Note that failure to comply with treatment may result in HP bacteria being resistant to many antibiotics, leading to more difficult and time-consuming treatment later (in Vietnam, many people have psychological drinking. The drug does not support the disease but does not go for re-examination so it is easy to lead to this phenomenon).

Prof. Dr. Nguyen Duy Thang recommends that HP bacteria will die in acidic environment and will thrive in high alkaline environment . Therefore, people with this bacterium should limit eating sour, spicy foods, limiting alcohol, beer, coffee, smoking . And to avoid antibiotic resistance, people should not be self-sufficient. intention to buy anti-HP antibiotics .
