The kidneys are responsible for filtering and flushing out unhealthy liquid waste from the body. However, kidney cancer—a relatively uncommon but serious disease that might often go undetected until it reaches advanced stages—could disrupt this cleansing process. It could also lead to more severe complications. Recognizing the signs and symptoms of kidney cancer is vital for early diagnosis and treatment. This post explores the most common signs of kidney cancer.

Blood in the urine (hematuria)
While hematuria may have various causes, including urinary tract infections, kidney stones, or injury, it should never be ignored. Even a small amount of blood in the urine warrants immediate expert attention.

Persistent back pain
Persistent or chronic back pain, particularly in the area around the kidneys, could be a warning sign of kidney cancer. This pain may be dull and aching, sometimes mistaken for muscle strain. If back pain persists despite rest and usual treatments, one must consult a healthcare provider for evaluation.

Fatigue
Kidney cancer may lead to constant and debilitating fatigue. This persistent tiredness often interferes with one’s daily activities and might be an early indicator of the disease.

A loss of appetite
A sudden or persistent loss of appetite is another sign. This, coupled with a sudden reduction in fitness levels, may point toward an underlying health issue that requires attention.

Swelling in the abdomen or lower extremities
Kidney cancer may sometimes cause swelling in the abdomen or lower extremities. This swelling, known as edema, occurs when excess fluid accumulates in tissues. It could be uncomfortable and is often associated with advanced kidney cancer.

Palpable mass
Patients may feel a palpable mass or lump near the abdomen. This mass may represent the tumor itself or an enlargement of the affected kidney. Any unexplained lumps or masses should be promptly evaluated by a healthcare professional.

High blood pressure
Kidney cancer might affect blood pressure regulation. Elevated blood pressure that is difficult to control with treatment may indicate kidney cancer or related kidney problems. Monitoring blood pressure is essential, especially if it remains consistently high.

Anemia
Anemia, characterized by a low red blood cell count and reduced hemoglobin levels, could result from kidney cancer. Anemic individuals may experience weakness, fatigue, and paleness, among other symptoms.
