Can You Live With One Kidney If the Other Has Cancer?

Yes, it is entirely possible to live with one healthy kidney, even if the other is removed due to cancer. In fact, many people live long, healthy lives with just one kidney—whether they were born with one, donated one, or had one removed surgically because of disease.

When kidney cancer is limited to one kidney, the affected kidney may be partially removed (called a partial nephrectomy) or completely removed (radical nephrectomy). If the remaining kidney is functioning well, it can usually take over the job of filtering waste, balancing fluids, and regulating electrolytes without significant issues.

The human body has a built-in reserve when it comes to kidney function. A single healthy kidney can do around 75% to 80% of the work that two kidneys usually do. After surgery, most people adapt quickly, and kidney function often remains stable long-term.

However, some lifestyle changes may be recommended to protect the remaining kidney. These may include staying well-hydrated, avoiding excessive use of painkillers like ibuprofen, and monitoring blood pressure regularly. Regular check-ups and blood tests help ensure the remaining kidney continues to function properly.

It is important to note that people with certain pre-existing conditions—like diabetes, high blood pressure, or chronic kidney disease—may need closer monitoring after kidney removal. But for most individuals without underlying kidney problems, living with one kidney is safe and manageable.

What Are the Kidneys and What Do They Do?

Introduction The kidneys are essential organs that play a vital role in maintaining overall health and well-being. These two bean-shaped organs, located just below the ribcage on either side of the spine, serve as the body's natural filtration system. Every day, they filter large volumes of blood, removing waste products, toxins, and excess fluid, which are then excreted as urine. While their primary role is to filter blood, the kidneys also regulate blood pressure, balance body fluids, support red blood cell production, and maintain healthy bones. Understanding what kidneys are and how they function provides valuable insights into their importance for health. This article explores the structure, function, and essential role of the kidneys in the body. The kidneys are essential organs responsible for filtering blood, balancing fluids, regulating blood pressure, supporting red blood cell production, and promoting bone health. When kidney function is compromised, it can lead to serio...
