There is a certain relationship between high specific growth factor and tumor. If high specific growth factor is measured in the body, the possibility of malignant tumors is relatively high, because specific growth factor belongs to one kind of tumor markers, which can be measured in the places where tumor blood vessels are rich in growth, for example, liver cancer, gastric cancer, breast cancer, endometrial cancer, ovarian tumors and so on. In non-tumor diseases, such as inflammatory and proliferative diseases, high specific growth factor can also be measured, for example, hepatitis, cirrhosis, uterine fibroids, tuberculosis, etc. There are also cases of high specific growth factor.
