Thank you all for the prayers and kind words. I have an update, I'll try to make sense but bear with me since I am not a doctor.
Son had surgery on Thursday. They removed the cancerous lymph node and test results showed it to be a highly aggressive form of Lymphoma. The good news is, further testing in the way of full body scans, bone marrow and the like showed no evidence of additional masses, tumors, etc.
He began an aggressive regimen of treatment today, which the doctor's are highly confident and optimistic that he can be cured. He has all of the right factors in his favor, so please keep him in your thoughts. He is looking at a minimum of six months treatment.
His biggest disappointment was that the Navy transferred him from his ship to Limited Duty status.
Thank you again for your thoughts and concerns. Hopefully, with help he will beat this.
