Whenever I have a little problem, like a simple headache, an itch, a sore, or even just a general uncomfortable feeling the first thing I always think of is "it's cancer". And then the next couple of hours or even days I can't focus on anything because I keep weighing the odds and deciding if it's worth going to the doctor for or not. If I decide it's not worth it I feel really bad - a mix of guilt and fear - but on the other hand you can't really go to a doctor saying "I think I have slightly more trouble breathing than usual and I have to cough like 3 times a day". On top of all that I'm only 20 years old so the chance of me having cancer is only 1% or so. But still my body won't listen to reason, and I still feel guilty and bad for not going to the doctor, I can't help it.
So what I want to ask is if there is like a general test for cancer that I could take once every x years. I know the answer is probably no as there are a million types of cancer, but even if it's just a test for metastasising cancer, that would take the feeling of guilt away. I wouldn't mind if it's a little expensive but of course it can't be outrageous.
Or if you had any other related advice it would always be welcome of course.
