How long would a person live if small cell carcinoma?

Confined to chest. Or limited disease, there is a hance of cure. If presenting with metastasis, there is a chance of surviving well for many, but few make it beyond 2 years. Small cells can occur at other organs. You need to see a medical and a radiation oncology doctor while your work up proceeds. (head mr, bone scan, chest/abd ct + contrast thru adrenals).
