Is lung cancer contagious?

Lung cancer is a relatively harmful physical disease. It can easily endanger life. The possibility of lung cancer being contagious is very small, but it is not completely impossible to spread. Lung cancer is generally spread through influenza. Cancer cells grow very quickly and can grow and spread with the patient's sputum.

Can lung cancer be passed on to family members?

The chance of lung cancer being transmitted is very low. It is not a contagious disease, but it is not completely uncontagious. Lung cancer is contagious under certain conditions. First of all, the source of infection, the susceptible population, and the transmission route are all indispensable. Otherwise, the disease will not be transmitted. And you should know that there are many differences between lung cancer and tuberculosis. Although both are problems with the lungs, in most cases lung cancer is not contagious. Cancer cells discharged through sputum will rapidly degenerate and necrotize due to the evaporation of water in the sputum. Even fresh sputum requires various nutrients and specific conditions to make cancer cells grow and reproduce in vitro. Scientists often have to go through a lot of hardships to successfully cultivate a living cancer cell, so cancer is not contagious.

In addition, patients with lung cancer must pay attention to the three early steps, namely early detection, early diagnosis and early treatment, and not miss the best time for treatment. Many people choose surgical treatment. Early surgical treatment is often effective. The earlier the treatment, the smaller the chance of recurrence.

However, lung cancer is a hereditary disease, and people with a family history are more likely to develop lung cancer than normal people. Although lung cancer seems to have a familial clustering phenomenon, there is no evidence to date that there are specific susceptibility genes for lung cancer. More and more studies support the view that lung cancer is caused by the interaction between genes and the environment. Genetic variations in carcinogen metabolism, DNA repair, and cell proliferation and apoptosis control genes may be important genetic susceptibility factors for smoking-related lung cancer. Therefore, the key measure to prevent and reduce the occurrence of lung cancer is to quit smoking.

But we need to understand that a heritable disease does not necessarily mean it will be inherited. Infection is an infectious disease caused by the spread of microorganisms including bacteria and viruses among people, such as tuberculosis, hepatitis, etc. Heredity is due to blood relationship, which causes many people in a family to suffer from the same disease. If one of the parents has a certain type of cancer, their children are more likely to develop the same type of cancer. In other words, people with cancer often have a clear family history of tumors. The survey results show that the incidence rate of cancer patients is higher among blood-related patients than among unrelated patients, and higher among close relatives than among distant relatives, while there is no obvious difference between paternal relatives and maternal relatives, indicating that the incidence of cancer is related to genetic factors.

Diet for patients with lung cancer and cough:

Patients with lung cancer and cough can eat more fresh fruits and vegetables. Such as apples, figs, strawberries, lemons, plantains, grapes, oranges, kiwis, walnuts, bitter melon, garlic, winter melon, carrots, cauliflower, tomatoes, spinach, pumpkin, cabbage, etc., which can moisturize the throat and relieve cough symptoms.

Living environment of lung cancer patients with cough

1. The room is well ventilated. 2. Keep the patient in a warm environment and avoid overcooling or overheating. 3. Try to breathe through your nose and use your mouth less. 4. It is best for the patient to sleep on his side. 5. Never eat raw or cold food. At the same time, walk underground as much as possible and take ginsenoside Rh2 Chinese medicine to regulate immunity, prevent complications such as cough, and control the metastasis and spread of cancer cells.

Family members of lung cancer patients need to do the following:

① Actively provide psychological care to enable patients to maintain a good mental state, build up confidence in overcoming the disease, and be prepared to fight the disease for a long time.

② Closely observe the frequency and depth of breathing. If severe breathing difficulties occur, give oxygen immediately and administer intravenous drip of prednisone or dexamethasone.

③ Pay attention to changes in body temperature. For mild fever, you can give a warm water bath, massage the Yongquan point, Hegu point, Quchi point, etc. For severe cases, you can use Chaihu injection, Chuanhuning, Qingkailing injection, prednisone, dexamethasone, etc.

④ Pay attention to changes in cough and accompanying symptoms, such as dry cough without sputum or little sputum that is difficult to cough up; if there is sputum that is difficult to cough up, pat the patient's back gently to help expectorate from bottom to top, and take licorice mixture, saxifrage tablets, and bisodium glutamate orally; in severe cases, suction sputum or perform tracheotomy.
