Waiting for biopsy

Had a hospital appointment to see my consultant on a Tuesday regards to some chest X-rays had done. Was told a shadow on my chest wall had shown on the x-ray and  was a concern for fast it seems to have spread. Said a biopsy needs to done and wanted me to go back on the Thursday for a opp to be done on the Friday morning...was told I'll be but sleep then a camera would be incerted down my wind pipe and then I'll have a cut bottom of my kneck for them to do the biopsy.. I'm still waiting on results.. I have been going out my mind with worry because of how fast things have been done.
