My dog Sadie has a mass in the middle of her lung and after ultrasounds and x-rays a cell biopsy was sent off on Friday afternoon to see what it is. We were told the results should be with us on Tuesday but its now Wednesday and nothing. I phoned the vets who said they would hurry it up, but how long do the results normally take to come through? We have also been told that they may not get any diagnosis because its only a cell biopsy and if they cannot get anything from the cells, she may have to be referred for a full biopsy and a CT scan. Its very worrying.
