Is malignant tumor a chronic disease

summary

The malignant tumor found in the physical examination of the hospital before was hospitalized at that time, and had a resection operation. But recently, I found that I was dizzy. I went to the hospital for reexamination and diagnosed that it was tumor metastasis to the brain. At present, I use traditional Chinese medicine to recuperate. Now let's learn whether malignant tumor is a chronic disease.

Is malignant tumor a chronic disease

First, I want to tell you that cancer is also a chronic disease. In medicine, cancer is a kind of malignant tumor originated from epithelial tissue, which is the most common type of malignant tumor. Correspondingly, malignant tumors originated from mesenchymal tissue are collectively referred to as sarcomas. A few malignant tumors are not named according to the above principles, such as nephroblastoma, malignant teratoma, etc. Generally speaking, "cancer" refers to all malignant tumors.

Second, tumor is a new organism formed by abnormal proliferation and differentiation due to the loss of normal regulation of local tissue cells at the gene level under the action of various oncogenic factors. Once a new organism is formed, it does not stop growing because of the elimination of the cause of disease. Its growth is not regulated by normal physiology, but destroys normal tissues and organs, especially in malignant tumors. Compared with benign tumors, malignant tumors grow fast, show infiltrative growth, prone to bleeding, necrosis, ulcers, etc., and often have distant metastasis, resulting in emaciation, weakness, anemia, loss of appetite, fever and serious organ function damage, and eventually cause death.

Third, the etiology of malignant tumor has not been fully understood. Many years of epidemiological research, experimental and clinical observation have found that environment and behavior have an important impact on the occurrence of human malignant tumors. It is estimated that more than 80% of malignant tumors are related to environmental factors. Various environmental and genetic carcinogenic factors may cause non lethal DNA damage to cells in a synergistic or sequential manner, thus activating proto oncogenes or (and) inactivating tumor suppressor genes, and changing apoptosis regulatory genes and (or) DNA repair genes, resulting in cell transformation. The transformed cells can proliferate polyclonally at first, and after a long multi-stage evolution process, one clone can expand relatively unrestricted. Through additional mutation, it can selectively form subclones with different characteristics, so as to obtain the ability of invasion and metastasis and form malignant tumor. Therefore, tumor is a genetic disease in essence.

matters needing attention

For patients with malignant tumor this disease, we should have a positive and optimistic attitude to treat this disease, at the same time, we should actively cooperate with the doctor's treatment, to achieve better treatment effect, in daily life, we should also timely correct some bad living habits, develop a good life habits, can be appropriate for some physical exercise, to improve self-confidence The physical quality of the body.
