My69 year old husband is diabetic, high blood pressure and having treatment for Prostate Cancer Treatment for cancer is Lucrin and Bicatilmide.This has been for 5 years. He has a very large swelling on the right side of his neck, and growing larger, at least 5cm x 3cm. I am not at all convinced, that, he was told, to leave alone, due to the fact that this very hard tissue surrounds the cartoid artery. Due to the medication, and the lack of testosterone, he is very lethargic and I find that he has concentration lapses, sleeps a great deal. What should I do next..!
