Bladder tumor is a common tumor of the urinary system. Tumors inside the bladder are malignant in most cases, so early detection, early diagnosis and early treatment of this disease should be done. Here, we will talk about how to deal with this disease. First of all, how to detect it as early as possible? Usually, patients start with blood during urination, which is often referred to as hematuria. This kind of hematuria often does not have any other accompanying symptoms and can be observed with the naked eye, which is called painless hematuria by professional doctors, and it often disappears on its own after having hematuria for a period of time and then reappears, which means that hematuria has intermittent characteristics and tends to give people a feeling that the disease has gotten better, so anyone who finds hematuria once should not take it lightly and must go to the hospital to see a doctor. Do not be afraid of trouble and let nature take its course, otherwise the discovery of the disease will be delayed. Sometimes patients may also have symptoms of painful urination and increased frequency of urination because of the accompanying infection. Once hematuria is found, everyone should look at the urine carefully to see if there are blood clots, the shape of the clots, and to observe whether the hematuria is present throughout urination or at the beginning or end of urination, and tell the doctor what you have observed, which can be useful in identifying whether the hematuria is caused by other diseases and can be helpful in determining the general location of the tumor. When you go to the doctor, you should also explain to the doctor whether you were taking any special medications before you found hematuria (such as whether you are taking anticoagulants such as aspirin), all of which will help the doctor’s diagnosis. Secondly, how can the diagnosis be confirmed as early as possible? The easiest test is ultrasound. It is important to keep urine when doing ultrasound, if there is no urine inside the bladder it will affect the diagnosis of bladder tumor by ultrasound. Generally ultrasound can find bladder tumor of 1 cm or more, sometimes it can find tumor of 0.5 cm or more. If ultrasound does not find abnormalities, CT or MRI can be done, both of which are more likely to detect small tumors than ultrasound. The most direct and valuable test is cystoscopy. Of course, cystoscopy is an invasive test and many patients are afraid to do it, but patients with bladder tumors must have it done. The pain of cystoscopy done by a skilled doctor is completely bearable, and many hospitals are now carrying out painless cystoscopy, which allows some patients with less guts to be painless during cystoscopy. Generally bladder tumors can be clearly identified through cystoscopy, and a biopsy specimen can be taken for pathological confirmation of the diagnosis. When a bladder tumor is detected through various tests, the patient should be treated as soon as possible. Currently, surgery is the most effective method. For early stage tumors, minimally invasive surgery can be used nowadays, which is to remove the tumor completely under cystoscopy with laser or various electric knives, such surgery will cause little damage to the patient and has good efficacy. For more advanced multiple tumors or tumors that are difficult to be removed locally, a major surgery is often done, which is a radical surgery to remove the whole bladder. Although this surgery is traumatic, the operation time is long and the quality of life is somewhat reduced after the operation, the therapeutic effect on bladder tumors is certain. After total removal of the bladder, a section of intestine is usually used to replace the bladder, and there are various surgical methods to replace the bladder with intestine, each has its own advantages and disadvantages, the specific method used The specific method should be decided by both professional doctors and patients. Adjuvant treatments for bladder tumors include chemotherapy and radiation therapy. It should be said that both treatments are effective for most bladder tumors. Nowadays, some patients with tumors that originally required total cystectomy have preserved their bladders by local surgery with chemotherapy and radiotherapy, and the long-term results are quite good. Patients with too advanced tumors can be palliatively treated with chemotherapy and radiation therapy, which is useful for prolonging life and relieving symptoms. How to prevent recurrence after surgery? Bladder tumor a tumor that is prone to recurrence, patients with local resection should have regular bladder perfusion with medications to help reduce the probability of bladder tumor approach. The drugs for perfusion are immune agents such as BCG, interleukin 2, etc. There is also a large group of drugs which are our most commonly used chemotherapy drugs, such as Famasin (a classic drug for perfusion chemotherapy for non-muscle invasive bladder cancer), mitomycin, etc. These are used for bladder perfusion after surgery to prevent bladder cancer recurrence, and the effect is quite good. Cystoscopy must be reviewed regularly after surgery, which is usually done once every three months in the near future, and the interval between cystoscopies is gradually extended with time. Both patients with local surgery and total cystectomy should have regular outpatient follow-up to detect recurring tumors early through ultrasound CT and other examinations. What should patients with bladder tumor pay attention to in their daily life? The focus should be on avoiding smoking including second-hand smoke, eating as little pickled food as possible, drinking more water, life should be regular and maintaining an optimistic attitude towards life. All this is meaningful to reduce the occurrence and recurrence of tumor. With the continuous progress of medicine, the treatment of bladder tumor will continue to develop, and patients with bladder tumor will definitely live longer and better quality lives.
