Experts say there are three ways for kidney cancer to metastasize

When kidney cancer develops to the late stage, it will metastasize. How much do you know about the metastatic pathways of kidney cancer? I hope the following experts' introduction can help you. Let you know more about the metastatic pathways of kidney cancer .

1. Hematogenous metastasis

Cancer invades the renal vein, causing cancer thrombus to form in the vein, which can metastasize to the lungs, liver, bones, etc. At the same time, the cancer thrombus can extend from the renal vein to the internal spermatic vein (clavicular vein), or the ovary and internal vaginal vein, causing metastasis to the spermatic cord, epididymis, broad ligament of the uterus, vagina, labia, etc. The incidence of cancer cells metastasizing to the renal vein and inferior vena cava is 20% and 10% respectively, which is the metastatic pathway of kidney cancer.

2. Lymphatic metastasis

About 15% to 30% of renal cancer metastasizes via the lymphatic pathway. On the left side, it metastasizes to the renal pedicle, the preaortic and left lymph nodes, and on the right side, it involves the renal hilum, the pre-inferior vena cava lymph nodes, and the lymph nodes between the aorta and the inferior vena artery. It can also metastasize to the neck, causing cervical lymph node enlargement.

3. Direct dissemination

Direct spread can go outward through the renal capsule to the surrounding tissues of the kidney or invade the renal vein and the inferior vena cava. If the renal pelvis is invaded, hematuria may occur clinically. At the same time, renal cancer can also invade the surrounding tissues such as the colon, pancreas, adrenal glands, peritoneum, liver, spleen, etc., which is also the metastatic pathway of renal cancer.

After reading the above brief introduction to the metastatic pathway of kidney cancer, I hope it will be helpful to everyone. Everyone should pay more attention to the metastatic pathway of kidney cancer, learn more about it, pay more attention to prevention in life, and treat it as soon as possible once it is discovered.
