4 warning signs of cancer in smokers

Cigarettes contain about 7,000 harmful substances, of which more than 60 are capable of causing cancer. Some research evidence shows that passive smoking also increases the risk of developing bladder cancer, according to the health website Medical News Today (UK).

Smoking increases the risk of bladder cancer

In addition to smoking, other factors that increase the risk of bladder cancer are old age, frequent exposure to harmful chemicals, radiation, recurrent urinary tract infections, chronic cystitis, having had cancer or having a family member with bladder cancer.

Smokers should watch out for the following warning signs of bladder cancer:

Blood in urine

This is one of the warning signs of bladder cancer. Blood will make the urine pink, red or brown. There are cases where blood clots will appear in the urine, usually very small clots that can only be detected by medical testing.

Change in urination habits

Bladder cancer will cause abnormalities in urination habits, such as increased urination, urgency or pain when urinating. These are also common symptoms of urinary tract infections. Therefore, patients can easily be confused. To determine the cause of the disease, it is necessary to go to the hospital for examination.

Pelvic, abdominal and back pain

Persistent pain and discomfort in the pelvic area, lower abdomen or back can be a sign of bladder cancer. Smokers should see a doctor if the pain persists without finding a specific cause or if they have taken medication or tried many methods without relief.

Unexplained weight loss

Weight loss is a warning sign of bladder cancer when the patient loses more than 5% of their total body weight in 1 month. However, this weight loss is unexplained, meaning the patient is not dieting, exercising or using other weight loss methods. This is also a notable symptom not only of bladder cancer but also of many other types of cancer, according to Medical News Today.
