Kidney cancer can cause early symptoms such as blood in the urine, flank pain, a lump, fatigue, and weight loss.

Nguyen, 29, had late-stage kidney cancer despite having no symptoms, leading doctors to remove his left kidney.

Kidney cancer often progresses silently in its early stages, with most cases discovered incidentally during abdominal ultrasounds or CT scans performed for other reasons.

People often dismiss early signs of kidney cancer, such as blood in urine, back pain, weight loss, fever, fatigue, swelling, or night sweats.

Nguyen Dinh Thuong, 14, diagnosed with kidney cancer, nearly gave up due to financial hardship until the Sun of Hope program (Hope Foundation - VnExpress) provided support for his treatment and recovery.

Smoking, excess weight, an unhealthy diet, and prolonged use of pain relievers can increase the risk of kidney cancer.
