I am 31 years old and have been diagnosed with a yolk sac tumour. I had to have an emergency operation when it became a erupted mass in my stomach. they thought it was a cyst at first then after 2 weeks i had the awful news of what it was. I have just got out of hospital after my first week of chemo and i found it really hard. My doctor is now advising that I should consider a hysterectomy as he doesnt think its all been removed. I have no children and my head is all over the place. Has anyone else experienced this type of ovarian cancer and treatment. Apparently its a rare germ cell type but if its caught quick enough the prognosis is good. My ca125 has increased to 825 last week but the ct scan shows it hasnt spread anywhere else.
