Jumping from a couple of days of nausea upon waking to brain cancer seems to be a very big leap to me.If this continues you must see a doctor. Sorry to alarm you but early morning sickness can be symptomatic of brain cancer.
I’m so sorry to hear about your granddaughter @Waffle it must be really difficult and upsetting for all of your family to deal with, you are totally correct that getting anything, including headaches checked out if they persist. But we have to be careful of jumping to conclusions and assuming on the forumOnce again I’m sorry. I did not want to be alarmist but my granddaughter was diagnosed with brain cancer at age two years and we have been going through a difficult time. Her earliest symptom was early morning nausea which I found out is a symptom of brain cancer.i am aware that there can be other causes of early morning nausea but if it continues for a long time it is best to get it checked out by a doctor.
