The fortune teller said that I had cancer.

In medicine, cancer refers to a malignant tumor originating from epithelial tissue, which is the most common malignant tumor. Accordingly, malignant tumors originating from mesenchymal tissue are collectively called sarcomas. A few malignant tumors are not named according to the above principles, such as nephroblastoma and malignant teratoma. Generally speaking, "cancer" refers to all malignant tumors.

Tumor is a new organism formed by abnormal proliferation and differentiation of cells in local tissues at the gene level under the action of various tumorigenic factors. Once a new organism is formed, it will not stop growing because of the elimination of the cause. Its growth is not regulated by normal body physiology, but destroys normal tissues and organs, which is especially obvious in malignant tumors. Compared with benign tumors, malignant tumors grow rapidly and are invasive, and are prone to bleeding, necrosis and ulcer. , and often transfer to the distance, leading to emaciation, weakness, anemia, loss of appetite, fever and serious organ function damage.

Cancer is a chronic disease that does not lead to immediate death. Through conditioning, you can prolong your life.
