Kidney cancer rates have 'soared' by 30% over the past decade, according to research.
The latest figures from Cancer Research UK showed the rates of people diagnosed have risen from 9 in every 100,000 to 12 people in every 100,000.
This means that cases hit 10,000 a year for the first time, up from around 6,900 a decade ago.
All age groups have seen an increase, with the largest in those 80 and over, the research found.
Experts believe obesity and smoking are isome of the main reasons for this sharp increase.
Additionally more cases have been detected through new imaging methods, such as ultrasound and computed tomography (CT), which can pick up cancers before patients have noticed any symptoms.
Kidney cancer is the eighth most common cancer in the UK. Each year 4,200 people die from the disease.
