Is lung cancer contagious?

The mortality rate of lung cancer is extremely high. I believe everyone is afraid of contracting this disease. Many people do not know the common sense of the disease, so they think that lung cancer is contagious. This is totally unfounded. Let's ask experts to tell you whether lung cancer is contagious.

In simple terms, infection is the transmission of a disease from one person to another through some means. Infection requires three conditions: a source of infection, a transmission route, and a susceptible population. Clinical data show that cancer patients themselves are not the source of infection.

Although lung cancer is not contagious, it can spread and metastasize in the patient's body. Cancer cells are a group of abnormal cells that have lost control and grow in an invasive manner. They not only destroy adjacent normal tissues and organs, but can also metastasize to all parts of the body through lymphatic and blood circulation, absorbing a large amount of nutrients, growing and proliferating rapidly, leading to systemic failure of the patient and even death. Despite this, cancer cells will not transfer from one person to another.

Lung cancer is not contagious, so there is no need to worry that the cancer cells of lung cancer patients will be transferred to your body. Only by correctly understanding lung cancer can we correctly treat lung cancer patients.

Through the above introduction, everyone should have some understanding of the contagiousness of lung cancer. I hope that after understanding this, friends can better care for lung cancer patients.
