In small cell lung cancer ‘extensive stage’, the average life expectancy is believed to be 9 to 12 months; and if the person does not opt for proper treatment, it can go down to 4 to 6 months. Approximately 15 percent of the people diagnosed with lung cancer suffer from small cell lung cancer ( SCLC ).

Stage four of liver cancer is fatal as it advances to several body organs like lungs, gall bladder, bones and even brain too. Prognosis of this stage is poor. The life expectancy of the patient will also be reduced to not more than one month.

Questions about life expectancy are often the first ones asked when someone is diagnosed with stage 4 non-small cell lung cancer, the most advanced stage of the disease in which cancer has spread (metastasized) from the primary tumor to distant organs. The median survival time for those with stage 4 lung cancer is around four months, which means that 50% of patients will still be alive four months after their diagnosis.

For stage 3b you have a 64 percent chance of surviving at least 5 years. For the most severe case of stage 3, stage 3c, the survival rate is 44 percent.

70% of cases at diagnosis have already spread to other areas of the body which places the cancer in a Stage 4 category. The 5 year survival rate for Stage 4 Neuroblastoma is 30%. 60% of patients with Neuroblastoma will relapse. Once in relapse, the survival rate drops to less than 5%.

It is important to understand that patients who have lung cancer spread to brain usually have a median survival of 4 months, after which 50% of patients die. However, people with a few metastases may live beyond this time.

With primary liver cancer, a person does not develop cancer of the lungs at the same time as he develops cancer of the liver. Instead, cancerous cells from the liver move to the lungs. The cancerous cells spread through the patient’s lymph fluid or blood.
