The bladder is an important component of our urinary system, functioning as a reservoir and an excretory organ for urine. The presence of cancer disrupts the regular activities of the bladder.

Bladder cancer has some warning signs and symptoms-

• The most common symptom is hematuria, which is the presence of blood in the urine. The urine may appear normal in color, even with a small amount of blood. However, there may be a significant amount of blood, causing the urine to appear orange, pink, or dark red. This symptom may be intermittent, meaning that blood may be present in the urine one day and then disappear, only to reappear again after a few days or weeks. There may be some pain or no pain associated with the presence of blood in the urine.
• People may feel a burning sensation before, during, or after pee. Men may feel pain in their penises before or after peeing.
• It may happen that someone is feeling the urge to pee but he is unable to pee.
• People may have frequent urination.
• Sometimes, you may have an urge to pee though your bladder is not full and your pee may not be clear.
• People may need to pee several times during the night.
• People may feel pain in the lower back side or one side of the body.

These are the most known warning signs of bladder cancer. It's very essential to visit a doctor if you have any of these symptoms.

Besides the signs and symptoms, it's very important to know about the facts that may trigger bladder cancer. Let’s know about the possible risk factors-

Smoking
When people smoke, some chemicals are excreted through smoke and some are excreted through urine. The deposition of harmful chemicals from the cigarette in the bladder may cause bladder cancer. 

Gender
Due to smoking and occupational chemical exposure, men are more prone to bladder cancer than women.

Age
The risk of bladder cancer increases with age. Most are diagnosed with this cancer are over 55 years old.

Certain chemicals
Exposure to arsenic or certain chemicals used in the manufacture of dye, rubber, leather, and textile may cause bladder cancer.

Previous cancer treatment or family history of cancer
Intake of anti-cancer drugs like cyclophosphamide increases the risk of bladder cancer. If any of your family members had bladder cancer, you may have the possibility of being affected by this cancer. Though this possibility is rare.
