Squib

Hello I was diagnosed with breast cancer in its early stages or though I thought and was told. However after successful operation to remove all lymph nodes I was told although at the moment I am cancer free there is a very high probability of it returning and have suggested radiotherapy and chemotherapy as a precaution. My problem is this, I am 70 years old, my m7m died of cancer at 56, my brother at 75. I am also due to travel to Australia next month when treatment is meant to start. I know I will be quite ill during treatment , without it I’ve got about 18 months to live. Do I just go ahead and live life to the full or have treatment. I have grown up daughters and grandchildren (all grown up) . My daughters have said it’s my decision but they don’t think I will handle the chemo plus I am due to fly to Australia in November to see my relatives and although I can hav3 treatment when I get home I’ve been told it won’t be so affective. I am frightened, scared but mostly don’t want m6 daughters to suffer like I did when I list my mum and my brother to cancer. HELP
