My dad was diagnosed with stage 4 lung cancer 3 weeks ago. He’s had all the scans and biopsies but is yet to see the oncologist and start treatment. He is extremely anxious and can see him mentally deteriorating, he just wants to start his treatment to know something is being done. His worry is that each day he goes without treatment, the worse the cancer gets and will spread further. How long do people generally wait from diagnosis to actually starting treatment? And is he likely to see an improvement in his cough, lack of energy and night sweats?
