Following breathlessness and a slight cough I was referred to A + E with suspected blood clot on lung, thankfully no clot was found. A ct scan revealed that fibrosis on left lung shown on previous ct scan was showing some changes. Also a d dimer blood test which is used in diagnosing blood clots showed a very high level. Found out later that this test is also highly indicative of an underlying or undiagnosed cancer. The test is classed as non specific and can be raised in a number of other conditions, none of which apply to me.

I've been advised to return for further ct scan in 3 months but have no further appointments or investigations meantime. I am living in a constant state of dread and fear and can't sleep. 

I would be very grateful if anyone has had any similar experience or advice.  Many thanks.
