Madam , 1st of all life and death is in the hands of god ,,, so no one can tell you ever how long will you live ,,, but what i can tell you is some statistical facts based on patients diagnosed with Papillary carcinoma of the Thyroid gland ,,
before this i want to bring you some good news i hope:
the treatment for this type of cancer is surgical resection and it is curative in most of the cases
even if the caner cells metastasized (usually to the cervical lymph nodes) they are very responsive for Radiotherapy with Iodine 131...
now the prognosis is EXCELLENT , 20 years survival = 90%
which means , after the time of diagnosis with 20 years you will find patients with this type of cancer are still alive and if they died it is probably due to another cause rather than the actual cancer ,,
so you are lucky to get this type of cancer , because other types like the anaplastic carcinoma of the thyroid is very aggressive and rapidly fatal
