It is impossible to generalize whether an 85-year-old man suffering from stomach cancer can be cured or not. In the case that he can tolerate surgery, if the tumor lesion can be completely removed through surgery, then there is a chance to cure stomach cancer; however, if he cannot be operated or if the tumor cells in his body have already spread and metastasized to distant places, then he basically cannot be cured. Stomach cancer is a kind of malignant tumor disease in digestive tract, which is caused by the uncontrollable growth of epithelial cells in gastric mucosa. Since the onset of gastric cancer is not limited to age, 85 years old people may also be jeopardized by gastric cancer. Although the physical function of the elderly is declining year by year, the elderly patients in the early stage of the disease still have the chance to have the tumor lesions completely removed through surgery if they can tolerate the surgery, so as to achieve the goal of curing gastric cancer in the end. However, if the physical condition of elderly patients is so poor that they cannot undergo surgery for radical treatment, or if they cannot remove the malignant tumor lesions completely even with surgery, or if they have distal metastasis and other adverse conditions, the possibility of curing the disease is relatively low, but they often prolong their lives through comprehensive treatment such as radiotherapy and chemotherapy. Whether stomach cancer can be cured or not is closely related to age, clinicopathologic stage and other factors, but age is not the only factor that determines whether stomach cancer can be cured or not. If you are suffering from stomach cancer, please consult the hospital in time, choose the appropriate treatment method under the guidance of doctors, face the disease with positive and optimistic attitude, and cooperate with doctors for treatment.
