Why do cancer cells become deadlier when they enter the lymphatic system?

Medically Reviewed by Checkmark Medically Reviewed By: Dr. Sravanthi Sunkaraneni

The main reason that the cancer becomes deadly in the lymphatic system is that it is connected across the body. So, cancer cells can spread quickly from the primary organ to other regions once they reach the lymphatic system. This is called metastasis, and it results in a higher cancer stage with a worse prognosis.

If cancer has spread to lymph nodes, they are removed surgically. Such a surgery becomes complicated when there is no way for the drainage of lymph fluid due to the removal of the affected lymph nodes. This can cause accumulation of the lymph fluid causing swelling. This condition affects the normal circulation of the lymph fluid within the body to cause a medical condition called lymphedema.

Lymphedema is a disease in which swelling occurs in the tissues due to the accumulation of undrained protein-rich lymph fluid. The condition mostly affects the arms and legs but can also occur in the abdomen, neck, chest wall and genitals. Severe lymphedema can increase the risk of skin infections and can also affect the ability to move from one place to another.
