“Bad habits are more addicted”, Quitting smoking can reduce the risk of bladder cancer in older women, says a study, adding that the most significant reduction in risk happened in the first 10 years after desisting.
Why smoking cigarettes are injurious to health?
Cigarettes are made from tobacco. The tobacco plant is the only plant ever discovered to contain the drug called nicotine. Nicotine is a very strong poison that can kill a human in less than an hour if even a small amount is injected into the blood-stream. But in cigarettes, it contains very tiny amounts of nicotine that are not deadly but are still very harmful to our health.
Why smoking is Addictive?
Smoking is said to excite pleasing and enjoyable emotions and smokers claim that it helps boost their mood. This is because cigarettes contain the addictive substance nicotine that stimulates dopamine in the brain, which is responsible for the pleasurable sensations. Smoking harms nearly every organ of the body. If this information helps you to quit smoking then read – cigarette smoking causes 87 percent of lung cancer deaths.
The researchers used various statistical models to analyze the association between the years since quitting smoking and the risk of bladder cancer.
The researchers covered data from 143,279 women in which all of whom had supplied information on whether they had ever smoked cigarettes, how much they had smoked and whether they were current smokers.
The researchers found that 52.7 percent of the women were categorized as “never smokers,” 40.2 percent as former smokers, and 7.1 percent as current smokers.
“Although bladder cancer is a fairly rare cancer type, representing an estimated 4.6 percent of new cancer cases in 2019, it is the most common malignancy of the urinary system, with high recurrence rate and significant mortality,” said Yueyao Li – Ph.D candidate from the School of Public Health, Indiana University in Bloomington, US.
“Smoking is a well-established risk factor for bladder cancer, but findings on the relationship between duration of smoking cessation and the reduction in bladder cancer risk are inconsistent,” Yueyao Li added further.
Li also said: “Our study emphasizes the importance of primary prevention (by not beginning to smoke) and secondary prevention (through smoking cessation) in the prevention of bladder cancer among postmenopausal women,”.
The study was published in the journal Cancer Prevention Research which found that the steepest reduction in risk occurred in the first 10 years after quitting smoking, with a 25 percent drop. The risk continued to decrease after 10 years of discontinuing of smoking.
If you are addicted or have just started then there can’t be a better time to leave it right now. Smoking is hateful to the nose, harmful to the brain, and dangerous to the lungs.
