The main concern with kidney cancer is that its symptoms usually do not occur until the disease has advanced beyond the curative stages.
Common Signs and Symptoms
The most common symptom of kidney cancer is blood in the urine, or hematuria. Blood in the urine is usually accompanied by pain in the flank side of the body and an abdominal mass.
Other common symptoms associated with kidney cancer include:
- Abnormal urine color
- Pain in the loin
- Weight loss
- Enlargement of one testicle (which is known as varicocele and it is usually the left testicle)
- Vision abnormalities
- Excessive hair growth in females
- Elevated calcium levels
- Paraneoplastic disease
One of the most common associated disorders with kidney cancer is the development of urinary tract infections. A urinary tract infection can occur when bacteria enters the bladder or the kidneys. Because cancer has taken over the kidneys, a bacterium is more prone to enter the system and cause such an infection.
