How do tumors in the human body arise and how to avoid them?

Tumors are divided into benign tumors and malignant tumors. Malignant tumor, also known as cancer cell, also known as cancer cell. An escaped cell? . As the name implies, this kind of cell is uncontrolled. Generally, cells can only divide several times in their lifetime, while cancer cells can divide dozens of times without being affected by apoptosis control. Benign tumors grow slowly and do not metastasize, which is harmless to human body. Tumors occur because the genes of cells are changed by some factors, which leads to cell division out of control.

Generally speaking, these factors can be divided into two categories, one is external and the other is internal. External factors include physical factors, chemical factors and biological factors. Among them, physical factors include ultraviolet rays, and chemical factors include ammonium nitrite and Aspergillus flavus. For example, we usually eat pickles with ammonium nitrite, but the dosage is not much, which will not have much impact on our health. Biological factors, such as some vampires and viruses, can be the cause of tumors. Internal factors, such as one's own emotions and hormone secretion, frequent emotional excitement or imbalance of hormone secretion may affect the formation of tumors.

So how to prevent tumors scientifically? First of all, we need to keep good eating habits. Deteriorated food usually contains various mycotoxins that can cause cancer, so we should avoid eating these foods. Cruciferous vegetables such as broccoli can prevent breast cancer, and tomatoes can prevent skin cancer. So eat more fruits and vegetables. Secondly, we should smoke less or give up smoking. The smoke in tobacco contains a variety of carcinogenic chemicals, which can lead to lung cancer, laryngeal cancer and esophageal cancer. At the same time, you should also drink less or give up drinking. Alcohol in wine can damage DNA and increase the risk of head and neck cancer, esophageal cancer, liver cancer and other cancers.

To sum up, maintaining good eating habits, eating less unhealthy foods such as barbecue and frying, smoking less, drinking less, exercising more, keeping physical and mental health and not being too excited can reduce the possibility of tumor occurrence.
