My Aunt age 87...fit, well, strong and positive has just been diagnosed High Grade B Lymphoma. Confined to left neck and shoulder, offered chemo but afraid of side effects. She would prefer a short time without illness than a prolonged time feeling unwell. At first visit, before Petscan she asked 'how long' and was told 6 months. I want her to try the chemo but have been told it is 'her body her decision'. Told If it goes wrong I will get the blame but I feel guilty for not guiding her. does anyone know the likely prognosis without treatment and what will happen as it progresses.
