What is Kidney Cancer

Kidney cancer is a group of diseases characterized by the uncontrolled growth of malignant cells within the kidneys, the organs responsible for filtering waste from the blood. While there are several types, the most common form in adults is renal cell carcinoma, which originates in the lining of the kidney's tiny tubes (tubules). Early detection is critical for effective treatment, as kidney cancer can often be managed surgically if caught before it spreads to other parts of the body.

What are the primary types of kidney cancer?

Kidney cancer is categorized based on the appearance of the cancer cells under a microscope. The most frequent classification is renal cell carcinoma (RCC), accounting for approximately 90% of all cases. Other, less common types include:

• Clear cell renal cell carcinoma: The most prevalent subtype of kidney cancer.


• Papillary renal cell carcinoma: Characterized by finger-like projections in the tumor.


• Chromophobe renal cell carcinoma: A rarer, typically slower-growing form.


• Transitional cell carcinoma: Originates in the renal pelvis where urine collects.

Who is typically affected by kidney cancer?

Kidney cancer most frequently occurs in adults between the ages of 50 and 70. It is statistically more common in men than in women. While the exact cause is often multifactorial, risk factors include smoking, obesity, high blood pressure, and certain genetic syndromes such as Von Hippel-Lindau disease. Currently, four members within the DiseaseMaps.org community are navigating their journey with kidney cancer, highlighting the importance of shared experiences in managing this diagnosis.

What is the underlying mechanism of kidney cancer?

The pathophysiology of kidney cancer begins when genetic mutations within the kidney cells disrupt the normal cycle of cell division. These mutations cause cells to multiply uncontrollably, forming a tumor that can interfere with the kidney's ability to filter blood. Unlike benign cysts, these malignant growths have the potential to invade nearby tissues or travel through the bloodstream to other organs if not addressed early.

Next steps

• Consult a urologist or an oncologist to discuss diagnostic imaging, such as CT or MRI scans.


• Review your family history to determine if genetic counseling is necessary for hereditary forms of kidney cancer.


• Join the DiseaseMaps.org community to connect with other patients and caregivers for emotional support.


• Discuss current clinical trials and treatment protocols with your care team.
