@kiastar- Good morning. Sandra sounds as if she has a wonderful support system. Has she been told yet that she has cancer? What does she think is wrong?

Given the wisdom that I see with you, I think that your niece will benefit greatly from your guidance.

My type of cancer is also an NSCLC. It's called Multifocal adenocarcinoma.

These lesions are considered primary, but there are a lot of them. I'm considered "stable" for now. I live in New England and use Mass General. My surgeon has treated me since my first tumor!

I hope that you will stay in touch. Do you think that your niece would like to touch base with COnnect? Since she is her mother's main caregiver we have a wonderful group that would support her.

Please know that I am here if I can be of further help. Stay safe and well. It's been very nice meeting you.
