Symptoms at Diagnosis
While kidney cancer is generally asymptomatic, about 1 in 10 people do experience symptoms like pain in the side of the body or blood in the urine. This could be a sign that the disease has advanced. Some people can also experience so-called paraneoplastic syndromes. These are reactions the body can have to any type of cancer and may include high blood pressure, weight loss, fever, anaemia, muscle mass loss, and loss of appetite. Syndromes more commonly associated with kidney cancer include changes in liver enzymes and blood platelets. These changes are usually discovered during tests and normally do not cause any symptoms.
Bone pain or a persistent cough could be signs that the cancer has spread through the body. This is known as metastatic disease.
Terms your doctor may use:
- Benign tumour: a non-cancerous growth which will not spread to other organs
- Malignant tumour: a cancerous growth which either grows continuously or in spurts. Malignant tumours can metastasize, which means they spread throughout the body
- Metastatic disease: when a tumour has spread to other organs or lymph nodes
- Renal: related to the kidney
