Is lung cancer contagious? Experts explain common knowledge about lung cancer

Lung cancer is a very harmful cancer, and cancer often brings death, which makes many people afraid of the arrival of cancer. In addition, many people in life do not know much about lung cancer, and even have some misunderstandings. So, is lung cancer contagious? Based on this question, let's take a look at the introduction of relevant content made by experts:

Experts explained that many people have a very poor understanding of lung cancer, which is why they ask if lung cancer is contagious. From the above, we know that lung cancer is a non-communicable disease but it is also a disease that is influenced by genetics.

Next, we will explain in detail the principles of whether lung cancer is contagious: cancer cells in the patient's body are a group of abnormal cells that have lost control and are invasive and long-lived. They not only destroy adjacent normal tissues and organs, but can also spread to all parts of the body through lymphatic and blood circulation, absorb a large amount of nutrients, grow and proliferate rapidly, and cause the patient's whole body to fail and even die.

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 matter, and the body destroys the cancer cells through its powerful immune rejection ability. Therefore, other people's cancer cells cannot survive in one's body.

The survey results show that the incidence of cancer patients is higher in blood relatives than in non-blood relatives, higher in close relatives than in distant relatives, and no significant difference between paternal and maternal relatives, indicating that the incidence of cancer is related to genetic factors. It has been confirmed that several tumors such as retinoblastoma, colon polyposis syndrome, Wilms tumor and neuroblastoma have a significant genetic tendency. Other cancers related to genetics include: gastric cancer, nasopharyngeal cancer, colon cancer, breast cancer, kidney cancer and esophageal cancer.

Experts remind you: If there is a family history of cancer in your family or family members, regular check-ups and arranging key protective measures are an effective prevention method, which has important clinical significance for the early detection, early diagnosis and early treatment of tumors.

Regarding the question of whether lung cancer is contagious, as mentioned above, we must know that the answer is no. We hope that through the above introduction, everyone can treat lung cancer and lung cancer patients correctly. Don’t let lung cancer patients endure the prejudice of the outside world while enduring the disease. We must let patients live a happier life.
