According to the survey, not only many young people are troubled by lung cancer, but also many elderly people suffer from lung cancer.
Why do elderly people suffer from lung cancer? In fact, this has a lot to do with the physical fitness of the elderly.
Today we will introduce the reasons why the elderly suffer from lung cancer, hoping to help everyone learn more about lung cancer.
Immunity decrease causes lung cancer
Modern medical research shows that the thymus gland begins to shrink after 50 years old.
As the thymosin associated with cell immunity begins to decrease, the immune function gradually decreases.
Therefore, its resistance and defense ability to tumors decreases significantly, which reduces the ability of human immune cells to eliminate some mutant cells, and ultimately leads to the occurrence of tumors.
Smoking history causes lung cancer
The occurrence of lung cancer is often related to long-term smoking and passive smoking, long-term adverse environmental factors and occupational factors.
It has a relatively long so-called “latent period”. Therefore, only after decades of adverse stimulation can tumors occur. As a result, the number of patients with lung cancer among the elderly has increased relatively.
The other disease interference
With the increase of age, the function of various organs declines and complications increase. Some early symptoms of lung cancer, such as cough, hemoptysis, chest pain, and shortness of breath, are often easily misdiagnosed as chronic bronchitis, bronchiectasis, tuberculosis, etc., delaying the diagnosis and treatment of lung cancer.
Lung cancer inheritance
For some patients who are prone to tumors through inheritance, the degeneration of tissue cells with age is also the reason for the increase of lung cancer and other tumors.
Everyone should have some understanding of why the elderly are more likely to suffer from lung cancer. I hope that everyone can do their best to prevent lung cancer.
