What is Stage 3 Lung Cancer?
Lung cancer is divided into four stages. The stages range from 0 to IV, with stage IV being the most advanced. Stage 3 lung cancer, also known as locally advanced lung cancer, is the third stage of lung cancer. At this stage, the cancer is more advanced and has spread to lymph nodes in the chest, but it has not spread to distant organs. It is important to note that stage 3 lung cancer is divided into three sub-stages, 3A, 3B and 3C, depending on the size and location of the tumor and whether the cancer has spread to lymph nodes.
What Happens if Lung Cancer is Left Untreated?
Lung cancer left untreated will continue to grow and spread to other areas of the body, including the bones, brain, and other organs. This can cause shortness of breath, pain, and other symptoms, depending on where the cancer has spread. As the cancer grows, it can cause fluid to build up in the lungs and chest, leading to difficulty breathing. If left untreated, the cancer will eventually lead to death.
How Fast Does Lung Cancer Spread Without Treatment?
The rate at which lung cancer spreads without treatment depends on the stage of the cancer and the individual’s overall health. Generally, the more advanced the cancer, the faster it can spread. Stage 3A lung cancer is usually slow-growing, while stage 3C is more aggressive and can spread quickly. It is important to note that even if the cancer is left untreated, treatments such as chemotherapy, radiation, and surgery may still be used to slow the growth and spread of the cancer.
What is the Life Expectancy of Someone With Stage 3 Lung Cancer?
The life expectancy of someone with stage 3 lung cancer depends on a variety of factors, such as the location and size of the tumor, the patient’s overall health, and the type of treatment they receive. Overall, the five-year survival rate for stage 3 lung cancer is approximately 12%.
How Long Can Someone With Lung Cancer Live Without Treatment?
Without treatment, the average survival time for someone with stage 3 lung cancer is one to two years. However, some people may live longer or shorter depending on their individual circumstances. It is important to note that even without treatment, some people with stage 3 lung cancer may live for many years if the cancer is slow-growing.
