My stepson just found out he has a urachal cyst and his urologist told him it can become urachal cancer. Can a urachal cyst turn into urachal cancer? Would removing the cyst prevent him from getting the cancer?

Can a urachal cyst cause urachal cancer?

Yes, a urachal cyst can become urachal cancer, but this is a rare occurrence.[1][2] One research study showed that urachal cancer was not found in any children with urachal cysts; however, 25% of adults with urachal cysts were found to have urachal cancer. The authors of this study suggested that the longer the urachal cyst remained in the body, the greater the chance it could become cancerous.[2]

How might a urachal cyst be treated?

In many cases, the diagnosis of a urachal cyst is only made when there are complications such as infection. Although some cases of infected urachal cysts have reportedly resolved without any intervention, surgical treatment is generally recommended which involves draining the cyst. Because there is a small risk that a urachal cyst may become malignant (cancerous), additional surgery is often performed to completely remove the urachus.[1][3][4]
