Hello,
Well, I am surprised if you have no normal worries. What about worrying about your boyfriend or girlfriend, your financial situation, the acne spots on your face, your hair-cuts, - something more appropriate to your enviable age.
It must be nice if you have so few "normal" things to worry about, that you can spare so much time on this desperately unlikely stuff.
It's usually doctors in training who get this, - when we first learn about the really rare stuff, we imagine we have it. But in fact, the mortality rate amongst junior doctors is so low that we get sought out by Insurance industry, wanting to insure our lives!
I think once a doctor graduates, and gets actual experience of how very common, minor illnesses are, - then a minor illness always comes first to mind when a patient presents with some complaint.
When I was in practice as a family doctor, I don't think I saw one new case of lymphoma or mouth cancer. Breast cancer is not so rare, I suppose, I did see that.
I don't quite know what would work for you. When I was younger, I was anxious so took up parachuting and skydiving, and ended up doing 300 parachute jumps altogether. When you're doing that, you only worry about whether your parachute is going to open properly, - everything else seems pretty trivial!
There are other hobbies that offer more of this appearance of danger, - perhaps one of those would concentrate your mind, if skydiving does not appeal. Mountaineering or motorcycle riding, or sub-acqua diving, perhaps.
Another good trick is to get acquainted with the modern concept of a "micromort," - that is a risk of dying of exactly one in one million. This is useful for putting risk into perspective. Skydiving carries a risk of 8 micromorts, - the risk of dying is about 8 per million.
Driving a car for 8 hours a day, actually carries twice that risk, - 16 micromorts. This is quite a good article, and has some intersting tables, (click and return),

Or you can search on <micromort> for other enlightening and interesting figures. Riding a motorcycle for one hour a day, - 60 micromorts.
So on the one hand, I'm suggesting you worry about ordinary things more, and also get something 'dangerous' to challenge yourself with. So as to have some good stories to tell your grand-children.
On the other hand, if you want to read up on medical matters, start more at the "common illness" end of the spectrum; and you could use "micromort" tables to find out what really *is* risky in this world.
Hope this helps.
Best wishes,
