I get very mild headaches at the same time every single night. last for 10-15 min. both of my parents have had brain cancer. could it be cancer?

For peace of mind,: getting yourself to a physician or healthcare provider to order an MRI with contrast on your brain is crucial at this point. There is nothing anyone including a brain cancer expert can tell you that will convince with 99.99% certainty that you do not have brain tumor. It is not likely given the random probability, but do yourself a favor and get it done. Thanks for trusting in HealthTap.
