Why don't cancer cells find the heart? There are no more than 2 reasons, but heart disease must be prevented
Everyone is afraid of cancer. The cancers with the highest incidence are lung cancer, stomach cancer, colorectal cancer, breast cancer and cervical cancer. Have you never heard of heart cancer? Many people wonder why the heart is not prone to cancer?
- There is no epithelial tissue on the heart
Cancer grows in three ways, one is expansile growth, one is invasive growth, and the other is exophytic growth. The reason for cancer is that electrons in cells are robbed, and cells that lose electrons will snatch electrons from other cells, thus entering a vicious circle, resulting in the production of too many misshapen protein molecules. At the same time, it will also lead to gene mutation, which will eventually form cancer cells and cause cancer. Gene mutations generally occur in epithelial tissues, such as the lungs, liver, kidneys, and breasts, which have epithelial tissues, so the possibility of canceration is high. Fortunately, there is no epithelial tissue on the heart, so cancer is rare. In addition, cardiomyocytes are terminally differentiated cells and contain genes that are extremely unlikely to go wrong, giving cancer cells no chance at all to grow.
- The blood flow of the heart is fast
The heart has the fastest blood flow of all organs, and cancer cells have no way to stay. In addition, the heart and blood vessels form a closed circulatory system, making it difficult for carcinogens to enter.
- Maintain moderate exercise
Arrange work and rest reasonably, pay attention to the combination of work and rest, and reduce stress by playing Tai Chi, meditation or yoga. Practicing yoga can reduce the inflammatory response of the body and reduce the damage to the heart.
- Active weight control
The fatter you are, the higher your risk of heart disease. Because people who are obese have high body fat content. A high-fat diet causes the body to store more and more fat, wrapping too much fat around the heart, which affects heart health. Therefore, it is necessary to control calorie intake and participate in physical exercise to maintain a normal weight.
- Control blood pressure
High blood pressure is a high risk factor for heart disease. When blood pressure is abnormally high, it will increase the pressure on the normal operation of the heart. Generally, the daily intake of salt should not exceed 6 grams. At the same time, we should also be alert to the invisible salt in the diet, such as soy sauce, potato chips and ham sausage. .
- Maintain a regular diet
Reasonably arrange three meals a day, and usually eat more foods that can protect the heart, such as red dates, kumquats, longan, grapes, black fungus, etc. Minerals related to the heart include potassium, magnesium and calcium. It is necessary to supplement minerals reasonably, pay attention to a diversified diet, and eat a small handful of nuts every day.
- Learn to release stress
Excessive mental stress or irritability can affect hormone secretion and the normal operation of other organs. Therefore, it is necessary to maintain a happy mood and face gains and losses correctly.
Usually participate in physical exercise such as cycling, walking or jogging, etc., and the daily exercise time should not be less than 30 minutes, at least 4 to 5 days a week. Eat at least 500 grams of vegetables and 200 grams of fruits every day, and control the body mass index between 18 and 25. Being too fat will increase the burden on the heart and cause myocardial hypertrophy. In addition, we must quit the bad habit of smoking, because the nicotine, nicotine and tar in cigarettes will stimulate the heart conduction system and increase the burden on the heart.
In addition, do not drink alcohol, alcohol will directly damage the heart muscle, make the atrium enlarge, interfere with the normal rhythm of the heart, and cause atrial fibrillation. Stay away from highly polluted environments, because air pollution will block the oxygen supply in the blood, making the blood more likely to clot and increasing the risk of cardiovascular disease. When there is unexplained chest tightness, it is necessary to go to the hospital for a heart examination in time.
