Kidney cancer is one of the most common types of cancer in the United States, with nearly 79,000 new cases diagnosed each year. Unfortunately, it was responsible for the loss of approximately 14,000 lives last year alone. As we observe Kidney Cancer Awareness Month this March, it is crucial to educate ourselves about this disease, its impact on patients and families, and how we can support those affected.
Understanding the Kidneys and Their Function
The kidneys are two bean-shaped organs located on either side of the upper back wall of the abdomen. Their primary function is to filter excess salt, water, and waste products from the blood, which are then excreted as urine. Beyond waste removal, the kidneys regulate blood pressure, produce red blood cells, and maintain overall fluid and electrolyte balance in the body.
When kidney function is compromised, it might result in serious complications, including chronic kidney disease (CKD) and, in advanced cases, end-stage kidney disease (ESKD).

What Causes Kidney Cancer?
It begins when healthy cells in one or both kidneys mutate, causing them to grow and divide uncontrollably. Over time, these abnormal cells form a mass called a renal cortical tumor. The exact cause of kidney cancer is not always clear, but some risk factors have been identified:
Understanding the risk factors may help people take preventive measures, such as maintaining a healthy weight, quitting smoking, and managing blood pressure levels.
What Are the Signs of Kidney Cancer?
Early-stage kidney cancer often presents no noticeable symptoms, making it challenging to detect. However, as the disease progresses, the following signs may appear:
If you experience any of these symptoms, it is essential to consult a healthcare professional promptly. Early detection can significantly improve treatment outcomes.

How Fast Does Kidney Cancer Spread?
It varies depending on the type and stage of the disease. Some forms of kidney cancer, such as renal cell carcinoma (RCC), can grow slowly and remain localized for years. However, aggressive types may spread rapidly to other organs, like the lungs, bones, or liver.
The spread of kidney cancer, known as metastasis, critically determines treatment options and prognosis. Regular screenings and monitoring are vital for patients with a history of kidney cancer or those at high risk.
Advanced Kidney Cancer and Its Impact
When kidney cancer reaches an advanced stage, it can severely impair kidney function, leading to complications such as:
- 1
Chronic kidney disease (CKD) – A progressive loss of kidney function.
- 2
End-stage kidney disease (ESKD) – The final stages of renal failure, where the kidneys no longer function independently.
- 3
Fluid and waste buildup: Causing symptoms like swelling, nausea, and shortness of breath.
At this stage, treatment focuses on managing symptoms and improving quality of life instead of curing the disease. Patients and their families should face difficult decisions about whether to continue aggressive treatments or transition to hospice care.

The Role of Hospice Care in End-Stage Kidney Cancer
For patients with end-stage kidney cancer, hospice care provides compassionate support tailored to their physical, emotional, and spiritual needs. Hospice care focuses on:
At Ascend Hospice Care, we aim to guide patients and families through this difficult journey with love, respect, and compassion. We provide comprehensive care to address the medical aspects of the disease and the emotional and social needs of everyone involved.
How to Observe Kidney Cancer Awareness Month
March is Kidney Cancer Awareness Month, a time to honor patients, caregivers, and those who have lost their lives to this disease. Here are some meaningful ways to participate:
By taking part in these activities, you can help spread awareness, support research, and provide hope to those affected by kidney cancer.
Kidney cancer is a devastating disease that impacts thousands of lives each year. By understanding what causes kidney cancer, recognizing the symptoms, and supporting those in the final stages of renal failure, we can make a difference.
If you or a loved one is facing end-stage kidney cancer, remember that you are not alone. We are here to provide the compassion and dignity you deserve during this challenging time.
