Scared...

So today my baby had an appointment today and long story short. Her doctor had discovered lymph nodes on both sides of her groin. And the confusing part is why are they inflamed when she not showing any type of illness ?? She has even gotten sick to even be developing lymph nodes especially down there. Today we have to go to the hospital to get her blood work done asap !! So they can get the results back today to see what's causing this. I'm so scared ... I have been even doing research on lymph nodes and all I'm reading is the worst that it's possibly linked to cancer. And I'm even more terrified since I done research on this. I hope there's nothing wrong with my baby girl. She is the love of my life and if anything ever happened to her I would definitely loose myself💯💯. So there saying she might have too have surgery if there is wrong with her or not to get them remove. Has anybody had a similar situation on this ?? If so what was your experience on this ? How did you handle it ?
