Most cases of renal masses do not show any symptoms, states the Washington University School of Medicine in St. Louis. Doctors usually find the masses accidentally during a diagnosis for another condition. For example, a patient experiencing abdominal pain may undergo a CT scan that happens to identify a mass in the kidney.
A cyst is the most common type of kidney mass, and it is prevalent in people aged 50 and above, states the Washington University School of Medicine in St. Louis. People with cysts do not typically experience any health problems. Radiologists may classify some cysts as simple cysts, meaning they may not need an intervention or a follow-up. However, some cysts can grow large, posing a challenge to radiologists. They may need periodic tests to observe their alterations and growth.
Some patients may develop cancer solid masses, which in most cases can be cancerous, states the Washington University School of Medicine in St. Louis. In such cases, doctors recommend a CT scan or a biopsy to evaluate the masses carefully. If the mass does not show cancer due to insufficient data obtained by the pathologist, a final diagnosis is not necessary but surgery is important. Doctors recommend surgery without a biopsy for cancerous cases.
