How long does it take to die from lung cancer without treatment?

As an expert in the field of oncology, I can provide you with information on the survival rates and prognosis of lung cancer. It's important to note that the duration of life after a lung cancer diagnosis can vary greatly depending on the type, stage, and individual factors of the patient. Lung cancer is generally categorized into two main types: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). The survival rates for these types differ significantly. For Small Cell Lung Cancer (SCLC), the overall 5-year survival rate for both stages (limited stage and extensive stage) is only about 6 percent. Without treatment, the average life expectancy for patients with extensive disease is 2 to 4 months, and with treatment, it is 6 to 12 months. For Non-Small Cell Lung Cancer (NSCLC), the survival rate is influenced by the stage at which the cancer is detected. If caught early (stage I), the 5-year survival rate is much higher compared to later stages. However, without treatment, the progression of the disease can lead to a significantly shorter life expectancy, although the exact timeframe can vary widely based on the specifics of the case. It's crucial to emphasize that these are general statistics and individual outcomes can differ. Treatment can significantly improve survival times and quality of life, even if a cure may not be possible. Early detection and a proactive approach to healthcare are key factors in managing lung cancer.

Small Cell Lung Cancer - The overall 5-year survival rate for both stages of small cell lung cancer (limited stage plus extensive stage) is only about 6 percent. Without treatment, the average life expectancy for extensive disease is 2 to 4 months, and with treatment is 6 to 12 months.
