Bladder cancer staging standards

Bladder cancer adopts TNM staging, T1 tumor, that is, very small tumor, just invades the bladder mucosa layer, T2 can invade the base layer, T3 invades the whole layer, T4 exceeds the bladder and has lymph node or distant metastasis. Grading is the main method of pathology, mainly based on the differences in the nuclear morphology and division of tumor cells, tumor cells are divided into three levels, of which level 1 is well differentiated, level 2 is moderately differentiated, and level 3 is poorly differentiated or undifferentiated. Bladder cancer is a malignant tumor occurring on the bladder mucosa and is the most common malignant tumor of the urinary system.

What are the early symptoms of bladder cancer in men?

There are no specific symptoms in the early stage of male bladder cancer, so it is difficult to detect bladder cancer in the early stage. Patients may show: frequent urination, which is manifested as an increase in the frequency of urination, but a variety of diseases can show frequent urination, such as prostatitis and prostatic hyperplasia in men, or the natural decrease in bladder capacity after aging, which can also show physiological frequent urination, so it is difficult to detect bladder cancer through the examination of frequent urination.

Hematuria is a relatively common symptom that can be found in the early stage of bladder cancer, and it is intermittent, painless, and visible hematuria throughout the whole process. Occasionally, there may be no obvious changes in the appearance of urine.

Is bladder cancer invading the lamina propria serious?

We can make a comprehensive judgment based on the patient's disease and tumor conditions, the depth of infiltration, age, and overall physical condition. Therefore, it is difficult to say whether T3 invasive bladder cancer can be cured. It varies from person to person. Invasive cancer refers to bladder cancer that has infiltrated into the submucosal layer of the lamina propria. Infiltration into the muscular layer is a dangerous manifestation. The bladder mucosal lamina propria is mainly composed of connective tissue, muscle, and blood vessels. The presence of the first stage of the lamina propria indicates that muscular layer invasion is possible.
