Will I be infected if I eat with a lung cancer patient?

1. Will I be infected if I eat with a lung cancer patient?

Lung cancer is not easy to be infected. Infection refers to the spread of bacteria and viruses through a certain way. For example, tuberculosis infection is caused by tuberculosis bacteria entering the body through the respiratory system and is transmitted through the air; hepatitis and AIDS are caused by hepatitis B virus and HIV through intravenous injection or contact. The causes of lung cancer are mostly caused by physical, acid and environmental factors. In other words, lung cancer does not have the basic conditions for infection. Therefore, lung cancer is not infectious, and advanced lung cancer is not infectious.

2. How do tumor cells spread?

In addition to infiltrating surrounding tissues, tumor cells can also invade the body's blood or lymph vessels, and reach other parts of the body through blood and blood circulation to form new tumors. This process is called migration, the former is local migration, and the latter is called distant migration or systemic migration.

3. Several types of possible carcinogens in daily life

In developed industrialized countries, 90% of lung cancer, 25% of coronary heart disease, and 75% of chronic obstructive pulmonary disease are caused by smoking. Smoking may cause cancers of the lungs, larynx, esophagus, bladder, mouth, throat, pancreas, renal pelvis, etc. Some scholars have reported that smoking is also related to the occurrence of cervical cancer, liver cancer, and sepsis. Scientific research in my country has shown that 75% of lung cancer in my country is mainly caused by smoking. About 1/3 of cancer patients are related to smoking.

3.2 Environmental pollution from diet and food ingredients

Because of the different environments, changes in diet, unhygienic diet, food contamination by chemicals, mycotoxins, etc., there is a close relationship with the occurrence of esophageal cancer, gastric cancer, liver cancer, colorectal cancer, etc. Human cancer due to dietary influences accounts for about 35% to 60% of human cancers.
