I am also grateful for you post. I have serous endometrial cancer, stage 4, and was given a very dire prognosis in January . I was given 'non-curative" chemotherapy earlier this year but denied radiotherapy "because it wouldn't extend my life". I traveled to Australia (from New Zealand) to get it where attitudes were more positive and technology more advanced. I have recently been prescribed Lexatrole, replacing Tamoxafen. Letrozole is an aromatase inhibitor, like Aromasin. My tumour was estrogen sensitive and I am post-menopausal. I had to have a bone scan before I started Letrozole , and will have regular ones, as a thinning of the bones is one risk with it. I continue to feel well and am doing my normal activities. I am currently training for a 300 km bike trail from Mount Cook to the sea over 5 days. I look forward to making my 80's like you!!
