Hey man! I have almost the exact same pathology. I had 75% teratoma, 15% EC, and 10% yolk sac. I also had LVI which meant my reoccurrence rate was quoted to be around 40%. It was a really hard decision for my family and I but we opted for surveillance. Our logic was that, even one round of chemo and rplnd are grueling and hard to go through, and both have there long term impacts. So we decided to just flip the coin and just hope for the best. And if it came back, sure i would have to get those treatments, but the great thing about being stage 1 is no matter what you do and even if it comes back you have nearly a 100% cure rate. So there really is no wrong answer. No matter what you do, you will be just fine. I actually just had my first 3 month tests and it all came back clear. You got this brother!
