If you see blood in your urine, even if it is just once, it could be a sign of cancer, a public health campaign warns.
Kidney cancer diagnoses have risen by a third in the past 10 years in England.
And the death toll has increased by 7%, with about 3,500 people dying from kidney cancer in England in 2011.
Public Health England (PHE) says the rise is linked to unhealthy lifestyles - smoking and obesity both raise the risk of kidney cancer - but early diagnosis could drive down death rates.
When kidney cancer is diagnosed at the earliest stage, the one-year survival rate is close to 97%, compared with about 32% at a late stage.
Visible blood in the urine is a symptom in more than 80% of bladder cancer patients and in most of those with kidney cancer.
Possible warning signs of cancer
- Blood in urine
- Needing to urinate very often or suddenly
- Pain while urinating
- Pain below the ribs that doesn't go away
If you notice blood in your pee, even if it's just once, tell your doctor.
