oh wow. Is this tumor cancerous? If its a threat to you then i hope you find a good understanding adult to talk to. And talk to your doctor about all your choices. Good luck . I hope all goes well for you.
A brain tumor sounds pretty serious and if it makes you black out then that can't be good for you at all and probably worse if you were pregnant since you could really hurt yourself. If it makes you black out then what are the chances of it doing more damage to your brain? Have you talked to your parents about your pregnancy?
No one can tell you what to do...it's your decision and you have to weigh out what is best for you.
you would better having surgery 12 weeks into pregnancy, people have had brain tumours removed in pregnancy and been fine, if it gets too bad you may be made to choose you or your baby if they refuse to operate, ask your doc what the risks are to you if you keep baby and wait for surgery? and why cant thet operate whilst your pregnant
What do your parents think? Honey I would start there. No one however, can tell you what to do with your baby or your body. Are you ok with abortion? Can you get a second opinion on surgery and pregnancy? Are there specialists that you can go to for answers?
This seems like an awful lot for you to have to go through at such a young age. I hope that you are able to talk to your family, your Mom is going to be the best person for help. I will be thinking of you and wish you the best.
