What Are the Different Types of Cancer Viruses?

Tumors are inherited, but the degree of genetic predisposition is different. In fact, all human tumors show a high tendency to occur in a certain population. For example, the incidence of nasopharyngeal cancer in Chinese is much higher than that in Japanese and Americans. In China, the incidence of nasopharyngeal cancer is highest among Cantonese. Cantonese who have migrated to Shanghai for more than 10 years still have an incidence rate of 3.64 times that of local residents in Shanghai. Conversely, foreigners who have migrated to Guangdong have The incidence of throat cancer is still much lower than the local Cantonese. Studies have shown that some cancers are related to a certain genetic change, and the most common genetic mutation and change in human cancer is the tumor suppressor gene p53. Mutations or changes in the p53 gene have been reported in 70% of colon cancers, 30% to 50% of breast cancers, 50% of lung cancers, and all small cell lung cancers.

Cancer virus

Some cancer patients have tumor susceptibility genes. As No. 17

Leukemia is a malignant disease that originates in the hematopoietic system and is characterized by the production and accumulation of a large number of naive and abnormal white blood cells in the bone marrow. Judging from the form, most leukemia cells are immature and morphologically abnormal white blood cells. Functionally, leukemia cells have the same characteristics as tumor cells: leukemia cells proliferate tumour-likely and cannot be controlled, often leading to the suppression and failure of bone marrow hematopoietic function, resulting in patients with anemia, neutrophils and thrombocytopenia; leukemia cells Infiltrate various tissues and organs throughout the body, such as the spleen,

Causes of cancer virus cancer

The occurrence of cancer is multifactorial, and the etiology has not been fully understood so far. Here are four main intrinsic factors and physicochemical biological factors.

(1) Internal factors

Nerve and mental factors: The cerebral cortex plays an important role in the pathological processes of human organs. Long-term stimulation of the nervous system can lead to imbalanced control of the brain, abnormal control of organ cell division and abnormal growth. Note that good mood is an important recipe for cancer prevention!

Endocrine factors: Endocrine is involved in regulating the metabolism and function of the body's organs and tissues. This process is directly related to the occurrence of cancer pathological processes. In particular, many cancers in women are caused by endocrine disorders, so be careful!

Genetic factors: The tumor itself is not inherited. The family inherits the quality of the tumor. Some people's physical qualities are prone to produce more tumor cells under the action of carcinogens, or the immunity of abnormal cells is significantly reduced, leading to cancer. occur.

The body's natural defense mechanism: Cancer not only occurs because of abnormal cells, but also requires the body's immune system to be suppressed. The immune system is your own Ministry of Defense. Under normal circumstances, the Ministry of Defense closely monitors every abnormal cell and eliminates it in time. If the Department of Defense does not work, those "rebellious" cells multiply and cancer will occur.

(Two) physical chemical biological factors

Physical factors: Proven sunlight and UV: Prone to cause skin cancer.

Some fibers (asbestos, glass wool, etc.): lung or malignant pleural tumors.

Ionizing radiation (X-rays): skin cancer, osteosarcoma, lung cancer, leukemia, thyroid cancer, malignant lymphoma.

Chemical factors: Several white chemicals have been found to cause cancer, typical examples are: dioxin and amine nitrite.

Biological factors: parasites and viruses.

What is this guy with cancer virus tumor

It is the patient's normal self-cells that have rebelled. Every normal cell in the human body is born with instructions. What tasks (functions) the cells perform, the boundaries (locations) of growth, and the life cycle are all defined. These instructions are written on the DNA. If the cell does not execute these instructions, it will play a prank, do not follow the instructions, do not adhere to the boundary (invasion transfer), and will not die when it expires. These greedy appetites and those with extraordinary growth rates have become malignant tumors, and have therefore become life-threatening protagonists. The occurrence of tumors is caused by the interaction of many factors in the body such as lifestyle, diet and nutrition, environment, mental mood, viral infection, endocrine and immune function, and heredity.

How cancer viruses deal with tumors

In 1983, Beichuanxun isolated 20 (S) -ginsenoside-Rh2 from red ginseng for the first time. It has been confirmed that ginsenoside Rh2 has anti-cancer activity that induces apoptosis, differentiation and regulates the cell cycle of cancer cells, and enhances the body's natural immune ability to inhibit the proliferation and metastasis of cancer cells.

Yes, fight for the first third! In 1984, a World Health Organization report pointed out that about one-third of malignant tumors can be prevented; about one-third of patients can be cured by early diagnosis and early treatment; and about one-third of patients can be prolonged by treatment. Time to live.

Cancer virus tumors must be diagnosed and treated early

Studies by the Zangfushu Institute of Food Therapy have shown that if several common cancers can be treated early, the 5-year survival rate can reach 70-95%, but the 5-year survival rate of advanced treatment is only 5-10%. The first treatment of tumors is very important, and early treatment is very important. Many patients have recurrence and metastasis of tumors soon after being treated by non-professionals. In professional cancer hospitals, such patients can be cured or survive for a long time, but they are delayed due to wrong treatment. Therefore, if you find a tumor, you should first go to a professional tumor prevention institution or oncologist. Experts remind you to find a cancer specialist hospital or specialist when diagnosing and treating tumors! China has established a three-level prevention and treatment medical network, cancer specialist hospitals and research institutes, oncology departments of general hospitals, tumor clinics, and tumor prevention and treatment teams. It is a major cancer prevention and treatment institution, including provincial and municipal hospitals, and medical hospitals. The affiliated hospitals of Military Medical University all have tumor-related departments.

More important is the early diagnosis of tumors. The tumor marker heat shock protein 90 (Hsp90) was found for the first time in China ^[1] , and its content in blood was positively correlated with the malignancy of the tumor, and it was launched in conjunction with the Ciming physical examination to find a pre-cancerous screening physical examination for early detection of cancer. ^[2]
