Kidney cancer care now keeps more of the kidney and has drugs for spread

If you or someone you love ever hears the words kidney cancer, here is good news. Care today often means taking out only the tumor and keeping the rest of the kidney. And when the cancer has spread, there are drugs that help people live longer.

That is the picture in a new expert review of how kidney cancer is found and treated. Many cases are now spotted by chance, on scans done for another reason. That is a real advantage, because it means doctors can often act early.

How the study worked

This is a review, not a new experiment. Experts pulled together what is known about renal cell carcinoma, the most common form of kidney cancer, and published it on Oct. 26, 2026, in The BMJ. Because it summarizes existing research, it does not test anything new, and it notes that some tumors resist treatment and that doctors still lack tests to predict who will benefit most from each option.

What they found

Renal cell carcinoma is diagnosed in people all around the world every year. The review shows how much the toolbox has grown for them.

Finding it. Doctors look at the tumor under a microscope, and they now also sort it by its molecular subtype. Diagnosis relies on a CT scan or an MRI, plus a biopsy for selected patients.

Treating a tumor that has not spread. Removing the kidney, called nephrectomy, is still the standard. For smaller tumors, partial nephrectomy is an option. It removes the tumor and leaves the rest of the kidney in place. For selected patients, doctors can also use ablation or targeted radiation.

When it has spread. In metastatic disease, combinations built on immune checkpoint inhibitors have extended overall survival. In some patients the response lasts a long time.

What are immune checkpoint inhibitors?

Your immune system has built-in brakes so it does not attack healthy tissue. Some cancers use those brakes to hide. Immune checkpoint inhibitors release the brakes, so your own immune system can go after the cancer. Pembrolizumab is one of these drugs.

What you can do today

You do not need to wait for a diagnosis to be ready. Take two minutes to write these two questions on a note in your phone, so they are there if you or someone close to you ever has a scan that finds a kidney mass:

1. Can this be treated while keeping part of the kidney?
2. Should I be seen at a center with experience in kidney cancer?

Then, if a scan ever does find something, you walk into the appointment with your questions already in hand.
