I believe that when mentioning cancer, everyone may feel afraid when they hear this word, because once the human body has become cancerous, life has entered the countdown stage, and it has indeed taken the lives of countless people and has become one of the killers that threaten human health.
The World Health Organization speculates that by 2020, 15 million new cancer patients will be added worldwide each year. At present, the incidence of malignant tumors in the mainland is 285.91 people / 100,000, calculated according to the population of 1.3 billion, which is 3.72 million new cancer cases in the country every year, 6 people are diagnosed with cancer every minute in the country, and 5 people die of cancer every minute.
As we all know, even if the current medical skills have been greatly improved, once there is cancer, and it is a more difficult cancer cell, it can only be maintained through conservative treatment to maintain the delay of life, and it is difficult to achieve a cure effect.
What is cancer
Cancer, also known as malignancy, is an abnormal growth of cells, there are more than a hundred types, including breast cancer, skin cancer, lung cancer, colon cancer, prostate cancer and lymphoma and so on.
Specific symptoms vary greatly depending on the tumor, and cancer treatment may include surgical therapy, chemotherapy, radiation therapy, and the like. Normally healthy cells in our bodies divide and replace themselves in a controlled manner, but cancer begins when cells change in some way so that their proliferation is out of control, and tumors are lumps made up of clusters of such abnormal cells.
Most cancers form tumors, but not all tumors are cancerous, benign or non-cancerous tumors do not spread to other parts of the body, nor do they produce new tumors, malignant or cancerous tumors crowd out healthy cells, interfere with human function, and absorb nutrients from human tissues.
Cancer is a process that spreads or metastasizes directly, causing malignant cells to pass through lymphatic vessels or blood vessels, eventually forming new tumors in other parts of the body.
How long does it take to become inflamed to cancer
There are also many people in life who initiate a situation, in fact, if there are some serious ones, if you don't pay attention, then it is likely to turn into cancer.
It may take about 10 to a few decades or so, so if a malignant change can occur in the short term, the shortest time is 2-3 months, which also varies from person to person.
But we can not take lightly some inflammation, inflammation according to the length of the course of the disease and the severity of the onset of acute inflammation and chronic inflammation, in acute and chronic inflammatory diseases, acute inflammation generally does not cause malignant tumors.
In the process of long-term existence and recurrence, chronic inflammation can easily lead to proliferative changes in tissue and organ cells and induce the occurrence of malignant tumors.
Reminder: 3 types of inflammation should not be "dragged"
1. Enteritis
Enteritis cancerous in general, if it is an inflammatory lesion such as duodenitis or chronic duodenal ulcer, it is generally not cancerous.
However, if it is colorectitis, long-term chronic inflammatory stimulation or dysplasia with glands or atypical hyperplasia, especially severe atypical hyperplasia, it is prone to cancerous tendencies.
In addition, Crohn's disease is more common in the clinic, which will be accompanied by inflammatory lesions, ulcers and other changes. The incidence of cancer was 6-20 times higher than in the normal control group, and the cancer rate of Crohn's disease in the large intestine was 20 times higher than that in the normal control group.
2. Hepatitis
Hepatitis may evolve into liver cancer under certain conditions, if it is only mild inflammation, after timely treatment, the inflammatory response is controlled, the disease will not develop in depth, and the possibility of evolving into liver cancer is much smaller.
However, if hepatitis is not treated in time or the treatment is not complete, the treatment method is not correct, causing the repeated delay of hepatitis activity, over time it will stimulate the proliferation of liver fibrous tissue, and gradually form cirrhosis, on the basis of cirrhosis, it is very likely that there will be cell malignancy, that is, transformation to cancer.
Therefore, hepatitis evolves into cancer to go through a relatively long period of progression, basically through the stage of cirrhosis will evolve into liver cancer, so after having hepatitis must be timely and correct treatment.
3. Pancreatitis
Pancreatitis may become cancerous, especially if the history of pancreatitis is relatively long. Long-term inflammatory stimuli may pose a risk of cancer, which requires aggressive treatment of pancreatitis to avoid causing greater damage.
Acute pancreatitis generally requires fasting, gastrointestinal decompression, intravenous electrolyte and energy supplementation, and maintenance of circulatory stability and water-electrolyte balance. Secondly, antispasmodic analgesia, inhibition of pancreatic exocrine and pancreatic gastric duct decompression, anticholine drugs and somatostatin can be used as histamine receptor antagonists.
Scientists agree that cancer may be linked to the following factors:
First: genetic factors, cancer is now considered a polygenic disease, people with a family history of tumors have a significantly higher chance of developing cancer than people without a family history of tumors.
Second: physical and chemical factors, including physical factors and chemical factors, physical factors in ionizing radiation is considered to be an important cause of cancer, chemical factors in toxic chemicals, such as formaldehyde, radon, toluene, xylene, etc., and tumorigenesis is very closely related.
Third: biological factors, the biological factors that are more closely related to cancer are viral infections, and several classic clinical examples include: the relationship between human papillomavirus infection and cervical cancer, the relationship between Epstein-Barr virus infection and nasopharyngeal cancer, and the relationship between hepatitis B virus infection and liver cancer, which all support the theory.
Fourth: psychological factors, people's psychological factors can not only lead to the occurrence of cancer, but also can affect the treatment effect of cancer. Long-term psychological pressure, depressed people have a higher risk of cancer.
Fifth: Some other factors, such as air pollution, bad living habits, etc., are related to the occurrence of cancer.
