There is much reason for lung cancer. Due to different reasons, survival rate occurs in different ratio. Survival rate affected by the following factors:
Age is the main factor of the survival rate in people. Young patients have a good immune system than old age patients. Therefore, treatment response is good in young patients of cancer than old patients. In addition, the survival rate increases in young patients.
- General health
It also affects the survival rate. If you have good health at the diagnosis time, you can survive for a long time. If you have good health then you can bear severe side effects of the treatment. It causes to increase the survival rate.
Gender also affects the survival rate. Females have more chances to survive than males patients in lung cancer. This occurs in every stage of lung cancer.
