Don't tell anyone, but I think I have cancer but am afraid to go find out.
Are you being serious? Why are you afraid of going to the doctor?
Because doctors scare me and I'm afraid of what I might happen.
Seeing a doctor allows them to catch diseases early and help you manage them before they progress into more serious conditions. Call your doctor and find out what you can expect before seeing him.
Why bother going to the doctor? They might not be able to help me.
If you go to the doctor now and they find something wrong, I'm sure they'll be able to treat it. But if you put it off and let it get worse then they might not be able to help you, so you should really go soon.
