Most people don’t have symptoms of renal oncocytoma VSports最新版本. If you do have symptoms, they might include:.
Experts aren’t sure what causes renal oncocytomas. Genetics (your DNA) probably plays a role, as some people born with hereditary conditions are more likely to get them V体育平台登录.
Certain conditions that run in families make it more likely for you to develop oncocytomas. For instance, tuberous sclerosis complex and Birt-Hogg-Dubé syndrome both cause growths on your skin and other organs VSports注册入口.
Healthcare providers use imaging and biopsies to diagnose renal oncocytoma. They may also do blood tests to check your kidney function V体育官网入口.
You may have already had a growth show up on an ultrasound, CT scan or MRI. To determine whether the growth is an oncocytoma or another, more serious type of tumor (like renal cell carcinoma), your provider might recommend a biopsy of the growth. A pathologist will then look at the tissue to make a diagnosis.

Your healthcare provider may recommend surgery to make an accurate diagnosis or to relieve symptoms. But renal oncocytomas that don’t grow or cause symptoms don’t necessarily need treatment.
If you need to have an oncocytoma removed, recommended procedures could include:
If you have a renal oncocytoma, talk to your provider if you start experiencing symptoms. It might also be helpful to understand whether you need follow-up imaging, and how often.
You may want to ask your healthcare provider:
Most of the time, oncocytomas don’t cause issues. Your provider may recommend scans periodically to make sure the growth isn’t changing quickly or spreading. If it starts to cause symptoms or grow quickly, your provider may recommend surgery to remove it.
Renal oncocytomas typically don’t come back (recur) if a provider removes them. But if you have a genetic condition that causes growths, you might develop multiple tumors or tumors in both kidneys that recur. Your provider can tell you what to expect in your specific situation.
It’s extremely rare for renal oncocytomas to become cancerous or spread to other organs. Oncocytomas with atypical (unusual) features might be more likely to spread than others. Providers can identify these features if you have the tumor biopsied or removed.
About 3% to 7% of all kidney tumors are renal oncocytomas, making them fairly rare.
A cystic oncocytoma is a type of tumor that contains areas of fluid, rather than a growth of solid tissue. They’re an uncommon form of oncocytoma.
One of the risks of medical imaging is that sometimes, providers discover things that would never cause you physical harm. But finding out you have a tumor can cause a lot of stress and worry. It’s normal to want to know if there’s a risk that it’ll spread and whether you’ll need surgery.
Fortunately, oncocytomas are considered noncancerous. It’s extremely rare for them to spread. Don’t hesitate to ask your providers about any concerns you have about monitoring or treatment options.
