What are the earliest symptoms of bladder cancer?

The onset of bladder cancer is a multi-factor, multi-gene, and multi-step process. The accumulation of abnormal genotypes and the effects of the external environment ultimately lead to the appearance of a malignant phenotype. Bladder cancer accounts for a large proportion of all cancers, and the incidence rate is on the rise every year. Experts say that understanding the early symptoms of bladder cancer can effectively prevent and treat bladder cancer. So, what are the earliest symptoms of bladder cancer?

The main points are as follows:

1. Frequent urination and urgency:

If cancer cells invade the trigone of the bladder, bladder irritation symptoms may appear earlier. If urinary pain occurs, it is no longer in the early stage.

2. Pain:

It is aggravated by bladder contraction and urine retention. If the tumor is located at the bladder neck, it may cause urethral obstruction; if the tumor invades the urethral orifice, hydronephrosis and ascending infection may occur, and severe patients may develop sepsis and uremia;

3. Hematuria:

Visible hematuria is a unique abnormal urination signal of bladder cancer and it almost always occurs.
