Is lung and pancreatic cancer contagious?

In reality, "talking about cancer is a fear" is a true reflection of people's fear of cancer. In people's conventional thinking, cancer is not only difficult to treat and endangers the patient's life, but also contagious. Lung and pancreatic cancer is called the "king of cancer", so, is lung and pancreatic cancer contagious? Let's ask an oncologist to give you a detailed introduction:

Experts pointed out that to understand whether lung and pancreatic cancer is contagious, we must first understand the causes of lung and pancreatic cancer, then understand the transmission principles of infectious diseases, and finally verify whether lung and pancreatic cancer is contagious through actual cases.

First, let's take a look at what factors induce lung and pancreatic cancer. According to research, the onset of lung and pancreatic cancer is generally closely related to lifestyle and diet. For example, alcoholism, drinking too much strong coffee, eating high-fat, high-animal protein foods, and smoking are considered to be the main causes of lung and pancreatic cancer. In addition, patients with diabetes and chronic pancreatitis are more likely to develop lung and pancreatic cancer than the general population.

Secondly, how do infectious diseases spread? Cancer is a group of abnormal cells that grow out of control and in an invasive manner. It not only destroys adjacent normal tissues and organs, but can also spread to all parts of the body through the lymphatic system and blood circulation, and absorb a large amount of nutrients, grow and proliferate rapidly, causing the patient's systemic failure and even death. Although cancer cells can spread or metastasize everywhere in the patient's body, they will not be transmitted from one person to another like bacteria and viruses. To oneself, other people's cancer cells are a kind of foreign body, and the body can destroy other people's cancer cells through its powerful immune rejection ability. Therefore, it can be seen that lung and pancreatic cancer is also a malignant change of cells, so it is impossible for lung and pancreatic cancer to be transmitted.

Finally, how can we prove this with actual cases? People have done experiments like this, putting animals with lung and pancreatic cancer together with healthy animals, and after a long period of observation, no direct transmission was found. In the hospital, different types of cancer patients lived in the same ward for a long time; cancer patients and non-cancer patients lived in the same ward for a long time, and no direct transmission was found. Medical staff had long-term contact with cancer patients, and their cancer incidence rate did not increase. A cancer patient lived with his family for a long time, and no transmission occurred. Based on this, it can be considered that cancer is generally not contagious.

Through the detailed introduction of oncologists on "Is lung and pancreatic cancer contagious?", we can understand. In recent years, with the increasing incidence and mortality of various cancers, people are too afraid of cancer, and then there is a saying that cancer is contagious. Through the detailed explanation above, please believe that no cancer is currently contagious. If people are unfortunately diagnosed with lung and pancreatic cancer, what should they do? Experts point out that due to the difficulty of surgical treatment of lung and pancreatic cancer, the postoperative prognosis is poor, and radiotherapy and chemotherapy are not very sensitive to adenocarcinoma, the treatment effect is poor, and the toxic side effects are large, so it is recommended that patients with lung and pancreatic cancer take traditional Chinese medicine for treatment.
