The timescale for the rest of my live with lung cancer metastasis bone and liver cancer. I was diagnosed early 2014 and I am 58 years old female?

Longevity. I am sorry to hear about your condition. The best person to ask is the oncologist (o) who is familiar with you and your case, as the o knows you best of all. There are different types of lung cancer and without knowing the type and the severity of the metastatic lesions, your answer will be best answered by your o or another o. Good luck.
