If you are suffering from colon polyps, most of them have a family history, and having a colon resection will not affect your life expectancy. However, if the colon resection is done because of colon tumor, and the tumor is prone to hematogenous metastasis or infiltration of neighboring organs, which is not easy to completely eradicate, it may affect the life expectancy. Even the tumor needs to see whether practical and effective control methods are taken after the surgery. If chemical drug treatment or Chinese medicine or herbal medicine treatment is given later to achieve good results, the impact on life expectancy will be smaller, and the survival rate and quality of life can be improved.
