According to media reports on July 13th， a 55-year-old man in Zhengzhou， despite leading a disciplined lifestyle， regular exercise， and abstaining from smoking， was unfortunately diagnosed with lung cancer.
Upon in-depth consultation， doctors discovered that the patient had been living under prolonged emotional stress within his family due to his wife’s constant complaints， leading to his feelings of depression and irritability.
Extensive clinical research has demonstrated that persistent anger， persistent unhappiness， and other negative emotions can significantly impair immune function through both the nervous and humoral systems. This impairment affects the immune system’s ability to identify malignant tumors， thereby creating a favorable environment for cancer development.
In psychology， these negative emotional states are often referred to as “Type C personality，” where the letter C stands for “Cancer.” Individuals exhibiting Type C personality traits have a notably higher incidence of cancers such as lung and breast cancer compared to the general population.
Therefore， maintaining a cheerful and optimistic disposition is as crucial for lung cancer prevention as quitting smoking and excessive drinking. It’s important to note that occasional anger is unlikely to increase one’s risk of developing lung cancer; rather， it is the chronic and persistent experience of such negative emotions that poses a significant concern.
