The word "cancer" first appeared in Wei Ji Bao Shu written by a Buddhist in the Northern Song Dynasty (1 170): "There are five cases of carbuncle, one of which is cancer ..." Cancer has the same original meaning and pronunciation as rock and roll. Traditional Chinese medicine often uses the original word "rock" as the name of the disease, which means that the texture is hard and the surface is uneven, which looks like a rock.
Cancer is a malignant tumor formed by the malignant proliferation of cells in human and animals due to some factors. It is produced because the mechanism of controlling cell growth and proliferation is abnormal. Cancer cells not only grow out of control, but also locally invade the surrounding normal tissues, and then transfer to other parts of the body, causing greater harm.
Basic classification of cancer:
1 malignant epithelial cell tumor
Lymphoma and leukemia
Sarcoma 3
4 mesothelioma
5 glioma
6 germ cell tumor
Placental tumor
There are many kinds of cancer, and the severity of the disease depends on the location of cancer cells, the degree of malignant growth and whether there is distant metastasis. Now there is a breakthrough in treating cancer in the world. As long as patients are optimistic and actively cooperate with the treatment, I believe that more cancer patients will be cured in the future.
