People are under increasing pressure. As a result, stress problems have become more common. Stress not only affects mental health, but also increases the risk of diseases including cancer.
Stress increases cancer risk
Chronic stress causes the endocrine system to continuously release cortisol, which leads to a decrease in immunity. As a result, the risk of infectious diseases and cancer increases.
In addition, when stress becomes chronic stress, you are more likely to feel depressed or even depressed. When the mood is low, the ability to cope with the disease will be significantly reduced. One of the reasons is that due to the low activity of NK cells (natural killer cells), the ability of patients with depression to increase lymphocytes will also decrease.
In many studies, the mortality rate of depression patients with cancer is much higher than that of patients without cancer.
Specifically, research published in the Journal of Clinical Investigation has shown that a stress hormone called adrenaline triggers a series of biochemical reactions that are conducive to the growth and spread of breast cancer. This study is considered to be the first scientific evidence of the effects of chronic stress on the development of cancer stem cells.
“You can kill all the cells you want in the tumor, but if the stem cells or stem cells are not destroyed, the tumor will still grow and metastasize. This is one of the studies. The first is to link chronic stress with breast cancer. Said Dr. Keith Kelly, one of the authors of the study.
Researchers at the University of Montreal in Canada conducted a study to assess the association between male cancer and long-term work-related stress.
The results show that within 15-30 years or even 30 years, chronic work-related stress is associated with an increased risk of lung cancer, colon cancer, rectal cancer, stomach cancer, and cancer. Lymph nodes. Hodgkin.
In addition, chronic stress can also promote the production of growth factors that increase blood supply, thereby accelerating the growth of malignant tumors.
Foods that are effective in preventing cancer
Free radicals are chemical molecules that lose one electron. In short, they are “out of balance.” When it loses balance, it tends to take electrons from other molecules to restore balance. This is very dangerous because it will damage other molecules, especially structural molecules. Cell composition.
Therefore, free radicals are closely related to free radicals and are important causes of many dangerous diseases.
Specifically, if free radicals attack lipid molecules in blood vessels, it will cause arteriosclerosis, high blood pressure, stroke…; free radicals attack DNA in the nucleus, which will help change the DNA structure, leading to mutations or cell death , Aging or many different diseases, especially cancer.
Antioxidants are compounds that can help neutralize free radicals. By neutralizing free radicals, antioxidants can prevent or slow down certain forms of cell damage and prevent cancer.
These compounds are naturally found in various foods, most notably fruits and vegetables, but they can also be synthesized and used in supplement form.
Antioxidants decompose active oxygen into water and oxygen, and at the same time eliminate their toxicity. The most typical antioxidants are superoxide disproportionation (SOD), vitamin A (β-carotene), vitamin C, vitamin E, flavonoids, astaxanthin, lycopene…
