@scareddad46, It is not unusual to feel scared and overwhelmed in this type of situation. The waiting is often difficult. I'm glad that your doctor is following up with a CT next week, which shows that she is taking this seriously. I would also take into account that she notes that you are low-risk for this to be cancerous. Of course, low-risk doesn't mean no-risk, and honestly sometimes no-risk people get cancer too. The only way to know more is to start with the scan next week.
Take a deep breath and try to do some things that may help take your mind off of it. Think of things that you enjoy and may be a distraction; go for a walk in nature, go to a movie, connect with a friend. Try to focus on what you know today, IE. there is something on the initial scan that needs follow up, but we don't know that it's cancer. Try to keep your mind from going to the worst-case scenario. Please keep us posted.
