Hi Barbara! My ovarian cancer (stage 3C), in the beginning, was also detected in a lymph node at my aorta three years ago. I had a complete hysterectomy with removal of this lymph node. Since then, my cancer had returned and showed up in various other lymph nodes. However, the chemo can kill the cancer in the lymph nodes as well. I have been receiving chemo again now for two years even tho there has been lymph node involvement with no spreading of the disease. The key is to keep up with all follow-up visits for early detection of any recurrence of the disease and start treatment ASAP. I also advise thinking positive and just eat as healthy as possible. They typically recommend a diet high in fruits and vegetables. Dietary protein is also very important while on chemotherapy. I wish your sister and yourself the best of luck! Debbie
