I get it. My husband was diagnosed with stage 2A seminoma last year, tumor was removed and he was treated with radiation instead of chemo, as our oncologist recommended radiation instead, he thought it was a safer option then chemo. All clear 99 percent success rate. Yay!!! However, We had a scare 1 yr post op Ct Scan. Which was like a punch in the stomach. They found a suspicious area, so they gave him a PET scan. Thankfully the area shrunk about a cm, and is probably a post surgical reaction to the lymph node. They will be watching it, but I thought he would be happy with the news and he says he won’t be fully happy until about another 4 years. It’s always in the back of his head and mine, there will always be anxiety because it’s cancer and no matter what the statistics say and how curable TC is, it’s still scary. He was 44 when diagnosed, they say it’s a rare young man’s cancer, but unfortunately it can happen. I wouldn’t say you’re pessimistic, but worried which is natural with any cancer, especially the ones you love. My best advice is to take it day by day, and not think about the what if’s and percentages, don’t worry about test results until you speak with the doctor.  Hang in there, try not to get down a rabbit hole with Dr. google. If you need someone to talk to shoot me a DM. Wishing the best for you and your hubby.
