What does tumor heterogeneity mean?

The heterogeneity of tumor refers to the differentiation degree of tumor, and also reflects the malignant degree of tumor from the lateral aspect. The more obvious the heterogeneity, the higher the malignant degree of tumor, the easier it is to show metastasis and invasion of other parts. Most malignant tumors are more obvious, easy to show metastasis and invasion, especially for pancreatic cancer of digestive system, liver cancer, and malignant tumors of blood system. The malignant degree is relatively high. In clinical treatment, it is also necessary to choose the corresponding treatment method according to the stage of the tumor and the location of the disease. For most solid tumors, surgery is the main treatment method after diagnosis.
