Do I have to use rituximab for non-Hodgkin's lymphoma?
Hello, tumor cancer is a new organism formed by abnormal clonal proliferation of cells in local tissues under the action of various carcinogenic factors at the gene level. Tumors are generally divided into benign and malignant types. All malignant tumors are always called cancer. No matter in cell morphology and tissue structure, tumor tissue is different from the normal tissue of its origin, 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. Invasive growth of malignant tumors can not only grow and spread in the primary site (direct spread), but also spread to other parts of the body (metastasis) through various channels. In terms of therapeutic effect, surgery and radiotherapy are both local treatments. Therefore, tumor chemotherapy experts not only pay attention to local tumors, but also pay more attention to the spread and metastasis of malignant tumors. Their viewpoint on tumor treatment is the viewpoint of cell index killing, so they emphasize multi-course and sufficient methods in order to completely kill most tumor cells. Different stages of cancer have different treatments. In the advanced stage of cancer, cancer cells have metastasized, and the hope of treatment for this situation is generally not great. It is recommended to treat according to the doctor's specific advice.
