Best answer: Why are lymph nodes removed during breast cancer?

That led doctors to believe that removing the axillary lymph nodes could reduce the risk of both cancer recurrence and metastases.

What is the prognosis for breast cancer that has spread to the lymph nodes?

If the cancer has spread to the regional lymph nodes, the 5-year survival rate is 86%. If the cancer has spread to a distant part of the body, the 5-year survival rate is 28%. Survival rates are about 9% to 10% lower in Black women compared to white women.

Effects of removing lymph nodes. When lymph nodes are removed, it can leave the affected area without a way to drain off the lymph fluid. Many of the lymph vessels now run into a dead end where the node used to be, and fluid can back up. This is called lymphedema, which can become a life-long problem.

What are the long term side effects of lymph node removal?

A possible long-term effect of lymph node surgery is swelling in the arm or chest called lymphedema. Because any excess fluid in the arms normally travels back into the bloodstream through the lymph system, removing the lymph nodes sometimes blocks drainage from the arm, causing this fluid to build up.

Does Chemo shrink lymph nodes?
