Cancer is a very serious malignant tumor. Patients with cancerous lymphangitis indicate that they have reached the middle to late stage of cancer, and the cancer cells have metastasized through the lymphatic vessels. For the treatment of advanced cancer patients, a comprehensive treatment approach is mainly adopted, which requires chemotherapy radiotherapy, targeted drug therapy, biological therapy, stem cell transplantation therapy, immunotherapy, Pd-1 therapy and so on. As long as the growth and development of tumor can be controlled and spread, patients can reduce symptoms, survive with tumor and prolong life expectancy. With active treatment, patients with advanced cancer can generally extend their life expectancy by 1-3 years.
