I can understand your concern. Treatment depends on spread of subplot cancer.  Whether it is limited to subplot area or spread in logic area.  Lymph node involvement, lymphatic or vascular invasion and grade of tumor.  So please send me your histopathological examination report of biopsy and ct scan report. So that I can help you further. Thanks for using Chat Doctor. Wish you a very good health. </s>
