hi carmen,
i cant give you much in the way of career advice, sorry, but i can give a little about your tumor.
first of all, i am sorry to hear that you have a tumor. secondly, don't panic. and third, do your best to stay positive.
there are options for this condition. you will need a good state of mind to be able to filter through all the information and make decisions for yourself and your family.
there are a lot of good people on this forum.... i am new at this, recovering from surgery recently, and the people on this site have been very supportive. i did not have any options, i had to have surgery and have it soon, because i was diagnosed very late in the game. however, it seems as if you caught yours pretty early, therefore giving you some options.
dont be bashful about asking questions on this forum, because not only are these people supportive, but some are very knowledgeable.
