Hi Dan,
sorry about your diagnosis. This is a very knowledgeable and supportive group and you did good in coming here. It appears your biopsy findings are inconclusive, so there is a high chance of your cancer (if it is cancer) being low grade. Has your doctor said your lymp nodes are cancerous? and you are at stage 4? Harmone therapy is definitely a starting point to arrest the cancer while you decide on further treatment. There are experienced members on this forum who will answer your questions shortly in more detail. You will find out if surgery is a viable option for you and also about the various types of Radiation available for your condition.
