For patients with early bladder cancer at the age of 75, surgery is still indicated; for some patients with advanced bladder cancer, the chance of surgery may have been lost. Bladder cancer refers to all kinds of malignant tumors of bladder, which can be staged according to the size of the tumor, regional lymph node metastasis and distant metastasis. Clinical treatment plans are usually formulated in conjunction with tumor staging, and age is not a direct factor guiding treatment. For early stage bladder cancer, the tumor diameter is relatively small, the tumor invasion site is small, the metastasis of regional lymph nodes and distant metastasis have not occurred, surgical resection is generally effective, and there is a great significance of surgery for patients at the age of 75 years old. For advanced bladder cancer that has developed distant metastasis, basically the chance of surgery has been lost, the effect of surgery is generally poor, and surgery is of little significance, radiotherapy, targeted therapy, etc. can be carried out to prolong the survival cycle. Age is not the main factor to decide the treatment method. When bladder cancer is found, it is recommended to seek medical treatment in time and standardize the treatment under the guidance of professional doctors to avoid delaying the condition.
