There isn't a magic wand. I was discussing this with a friend yesterday who also is living with cancer. She said people shouldn't consider themselves cured after treatment for early stage cancer. Once you have it, there is no cure. They can treat it until there is no sign of cancer to be found through surgery, radiation, chemotherapy, and other therapies. They can run out of tests to find it. They can tell you that you are done with treatment. They can tell you that you have a good prognosis. But they can't tell you, you don't have any cancer cells left in your body.
Once you have a cancer diagnosis, early stage or not, you can't assume that you are safe once treatment is done. You have to be vigilant and get follow up tests and treatments. You can live a normal life but you can't escape the fact that it was in your body once and they didn't cured it - they removed any signs of it and can't find any more - but they have no way of knowing if they got it all.
Am I being grim and morbid? Or am I facing facts? My friend was telling me this because another friend of her's just died who was diagnosed with early stage breast cancer just three years ago. She was treated but it came back. There is no magic wand.
