Bevacizumab, ramucirumab, and aflibercept are drugs that can cause a lot of protein in the urine. This is called proteinuria. Doctors have known this for a while. But what they don't know is if these drugs can also hurt the kidneys. This is a big question. It needs more study.

These drugs are used to treat cancer. They stop blood vessels from growing. This can help stop cancer from spreading. But they can also cause side effects. One of these side effects is proteinuria. This is when the kidneys leak too much protein into the urine.

Proteinuria can be a sign that the kidneys are not working well. But does this mean the drugs are causing kidney damage? Or is it just a side effect that goes away? This is what doctors are trying to figure out.

There have been some studies. But they are not enough. Doctors need more information. They need to know if these drugs are safe for the kidneys. They also need to know if there are ways to prevent kidney problems.

This is important. Because these drugs are used a lot. And many people have kidney problems. So, doctors need to be careful. They need to watch their patients closely. They also need to keep studying these drugs.

In the meantime, people taking these drugs should talk to their doctors. They should ask about their kidney health. They should also tell their doctors if they have any side effects. This can help doctors keep them safe.
