Can Chinese medicine treat tumors?
1. Tumor tissue is different from its normal tissue in cell morphology and tissue structure to varying degrees, and this difference is called atypical. Atypical is the morphological manifestation of abnormal differentiation of tumor. Small heteromorphism means high degree of differentiation, while large heteromorphism means low degree of differentiation. Distinguishing the size of this dysplasia is the main histological basis for diagnosing tumors and determining their benign and malignant. The atypia of benign tumor cells is not obvious, and it is generally similar to its source tissue. Malignant tumors often have obvious atypia.

Third, the tumor nucleus is larger than the normal nucleus, and the size, shape and staining of the nucleus are different. And there may be binuclear, megakaryon, multinuclear, exotic nuclei and dark nuclei (due to the increase of DNA in the nuclei). Chromatin is coarsened and unevenly distributed, and often accumulates under the nuclear membrane, which makes the nuclear membrane appear hypertrophy. The increase of mitotic images, especially when asymmetric, multipolar, frustrated and other pathological mitoses appear, is of diagnostic significance to malignant tumors. The abnormal nuclear changes of malignant tumor cells are mostly related to polyploid or non-integer ploidy of chromosomes.
Generally speaking, the ultrastructure of benign tumors is basically similar to the tissue from which they originated. Malignant tumor cells show different atypia according to their differentiation degree. Generally speaking, malignant tumor cells are usually absolutely or relatively obviously enlarged, and the nuclear membrane may be invaginated or protruded, making the nuclear morphology irregular or even forming a single nucleus. Cytoplasmic organelles are usually reduced in number, stunted or abnormal in shape. Cell connection is often reduced, which is beneficial to tumor infiltration and growth.
