Analysis of specific symptoms of bladder cancer

Although some bladder cancer patients have obvious symptoms when they develop the disease, there are still some people who are different. They do not have any obvious symptoms in the early stages, which is very unfavorable for our treatment. For those who have already suffered from the disease, we cannot change this reality, but it is still necessary for you, a healthy person, to understand its symptoms.

1. About 75% to 78% of bladder cancer patients suffer from hematuria. The symptoms of bladder cancer can be painless or intermittent, and sometimes stop on their own. Painless macroscopic hematuria is the most common symptom, which can occur in more than 80% of patients, of which 17% have severe hematuria, but 15% may only have microscopic hematuria at the beginning. Hematuria is mostly intermittent throughout the whole process, and can also be manifested as initial hematuria or terminal hematuria. Some patients may discharge blood clots or necrotic tissue. The duration of hematuria and the amount of bleeding are related to the malignancy, stage, size, number, range, and morphology of the tumor, but they are not necessarily proportional. Carcinoma in situ often manifests as microscopic hematuria, and hematuria in urachal carcinoma of the bladder may not be obvious. Bladder tumors of non-urothelial origin may not have hematuria if the lesions do not penetrate the bladder mucosa.

2. Many bladder cancer patients experience bladder irritation symptoms such as frequent urination, urgency, and pain during urination in the early stages of cancer. If the tumor ruptures, is infected, and the bladder muscles spasm, the symptoms of bladder cancer may be more obvious in the early stages. They may also be accompanied by chills and fever.

3. If the bladder cancer tumor invades widely and deeply, pain may occur, which is aggravated by bladder contraction and urine retention. If the bladder cancer tumor is located at the bladder neck, the symptoms of bladder cancer may cause urethral obstruction and even urinary retention. If the tumor invades the urethral orifice, hydronephrosis and ascending infection may occur, and in severe cases, sepsis may occur.

We must pay attention to our own health. Although material conditions are better now, this is not entirely a good thing. The environment and other aspects still have a great impact on us. If we are not careful, we will suffer from diseases such as bladder cancer.
