Hello @linpvc, The edges of the nodule are slightly spiculated, or slightly jagged, not smooth or rounded. Keep in mind, that these scans are read by human radiologists, and they can have different opinions. In seeing radiology reports over the past 4 years, some will choose to mention certain things, while others are more brief. "Slightly" should be taken into account, the radiologists didn't say that this is fully spiculated. That's good.
From taking a look at some of your other posts it looks like this nodule has grown in the past 6 months. That growth along with the slight spiculation adds to the risk and concern. The only way to know what it is for sure, is to get a sample of it for the pathologists. It sounds like you are on the right track for that procedure. That's great! It's never easy to wait for appointments though. How are you handling the down time between appointments? Have you come up with methods to keep your mind off of this?
