Please can someone give me some answers or advice please.
Hi JENJEN4 and a very warm welcome to the online community which I hope you'll find is both an informative and supportive place to be.
I don't have any experience with "loss of fatty hilum in lymph nodes" but can see that you've joined the head and neck cancer group so wondered if it was related to cancer that you've been diagnosed with in that area of your body. If this is the case, then starting a new post in that group should mean that you'll get group members from there popping on to help if they can.
It would be great if you could put something about your diagnosis and treatment into your profile as it really helps others when replying to you and also when looking for someone on a similar pathway. It also means that you don't have to keep repeating yourself. To do this click on your username and then select 'Profile'. You can amend it at any time and if you're not sure what to write you can take a look at mine by clicking on my username.
