I am so bloody worried. I had a urine and blood test. Bloods came back fine but was waiting on urine test as I had white floaters in my urine. Well today I get a letter from my surgery saying"

We are in receipt of the result of your recent urine test dated 06 Oct 2016 and should be pleased if you would call into the surgery in order to collect the form and bottle require to repeat this urine test"

I'm panicking that I have something that could turn out to be cancer :(
