The first warning sign of kidney and bladder cancer is blood in the urine (haematuria). You may see this as a pink, brown or red discoloration. The discharge is episodic and is usually painless.
You may also feel a burning sensation during urination. You start to experience an increased need to urinate, the frequency increasing during the night. Although you might feel the necessary urge to urinate, you might be unable to pass urine.
You start to experience lower back pain on one side, (area above the pelvis, and below the ribs in the abdomen). The onset of the pain is sudden and can range from a dull ache or a sharp pang, and usually lasts for weeks.
You might start feeling tired more often. This fatigue will be easy to differentiate as it is usually unresolved by sleep and starts to affect your performance during the day.
You may also experience fever, not caused by cold or flu.
The onset of cancer will leave you having a loss of appetite and unexplained weight loss.
During the advanced stages of the cancer, you start to notice swelling in your ankles and legs. You may also experience bone pain.
