Kidney cancer may develop asymptomatic for a long period of time. Although the tumor is growing in your kidney, it causes no significant signs or symptoms that may indicate its presence. In most cases, when you finally experience pain, the cancer is already advanced.
Some kidney cancers are detected during an ultrasound or radiography performed for another medical condition. However, as the cancer is completely installing in your kidney, you may experience severe pain.
Although these symptoms below are not necessarily indicators of kidney cancer, they are often signs that indicate not only that you have the disease but it is already advanced.
- blood in your urine
- perceptible lump or mass in the region of your kidneys;
- persistent abdominal or back pain just below your ribs
- intermittent fever
- unexplained weight loss
- general malaise
