I have just been fast tracked for colposcopy by my GP . It came back with no issues but as my husband was diagnosed with prostate cancer last year I am continuously worried even without symptoms now about possible bowel cancer. 
my fob fit test last September was negative and as I said I have no symptoms at all but it is constantly on my mind 

is this normal to have these worries 

it seems so illogical and there are times I tell myself it is highly unlikely that I do have it but due to recent events I cannot stop thinking about this
