Blood Drug Testing

i have brain cancer but normal blood chemistry & CBC results?

i was diagnosed with acute lymphoblastic leukemia for almost a year now and undergoing monthly chemotherapy. doc said im nearing remission and have normal CBC results for a month now. but last month i experienced a month long head ache, so sever i thought i was dying. i had my CSF checked via lumbar puncture by another doctor. found out (+) to brain cancer with 28WBC (normal is 5-10), 99% lymphocytes, 1% segmenters. in short i have brain cancer so she gave me chemo via the same lumbar puncture( intrathecal, as she mentioned) what i am curious about is the fact that my CBC results are already a month long within normal range. and until the very moment i was hospitalized for severe headache CBC and blood chemistry(electrolytes, BUN, crea, etc) are all perfectly normal how come i was nearing remission, have normal labortory tests results, and yet (+) to brain cancer???? pls help me understain how come this happend and why is it possible? i am not in denial

1. my son had brainstem glioma (cancer) and every test done showed nothing until the cat scan , which made them do a mri , which showed the tumors . he had 2 tumors both in the pons.during chemo , all his tests were fine , his platelets never even caused any problems . he didnt lose his hair and was never sick. cancer is a strange disease , there is just so much that we dont understand yet. i will keep you in my thoughts and prayers........
2. What did your MRI of the brain show? It is possible to have the cancer spread to central nervous system(brain+spinal cord+surroundings) and have it in remission elsewhere. Brain etc. is behind the so called blood brain barrier and is immunologically also somewhat different from other parts of the body.So it is possible, unfortunately. Often blood tests are normal, when we have a so called primary brain tumor like glioma which is not at all anywhere else than in brain. If I understood correctly, your tumor was first elsewhere and then went to brain etc.?
3. Yes its normal. don't forget to take Green tea ! It helps against leukimia
