If blood work, neurology report were all normal and physician did an examination and doeant suspect a brain tumor, am i most likely safe?

Yes: I assume that you do not have unexplained nausea or seizures. Good luck.

Can't tell you: I don't have enough information to advise you about this. When a brain tumor is a serious clinical consideration, usually an MRI scan will be done as the best test to find one if it is there. You don't describe that, but it could be because your doctors have too little reason to suspect a brain tumor. You should have a full discussion of this with your doctor, who has all the data.

Yes: You are not likely to have a brain tumor after a thorough eWorld up. If your doctor thought you had a brain tumor I expect he would have ordered a CAT scan or MRI. If you are very anxious about a tumor, speak to your doctor about one of these imaging tests
