I. Alcohol Not a Risk Factor

The consensus of scientific medical opinion is that alcohol does not increase the risk for bladder cancer. To the contrary, it appears that drinking alcohol may reduce the risk of developing the disease.

Major medical groups have examined all researrch evidence about alcohol and cancer. They conclude that drinking does not increase the risk of developing the disease. The organizations include these.

  • National Cancer Institute1
  • American Cancer Society2
  • Cancer Research UK4
  • American Society of Clinical Oncology3
  • Mayo Clinic5
  • Sloan-Kettering Cancer Center6
  • and other organizations7

II. Research Evidence

The research evidence is extensive. It incluses these.

alcohol and bladder cancerA study of over 120,000 subjects in the Netherlands. It found no relationship between drinking and bladder cancer.8

Analysis of high alcohol intake northern Italians. It found no association, even at high levels of consumption.9

Researchers made a very large study in Massachusetts. They found no association, except that beer significantly reduced bladder cancer risk.”10

Doctors did a population-based case-control study in Los Angeles County. They found that “alcohol consumption was strongly associated with reduced risk of bladder cancer.” For example, those who consumed more than four drinks per day had a 32% reduced risk of bladder cancer. That’s in comparison to those who did not drink alcoholic beverages.11

It appears that drinking alcohol may reduce the risk of bladder cancer. However, more research is necessary to be certain.

III. Symptoms

Symptoms of bladder cancer can include

  • Blood in urine
  • Frequent urination
  • Urinary tract infection
  • Abdominal pain
  • Back pain12

Having any of these symptoms does not mean that a person has bladder cancer. However, a person with any of these problems should discuss it with a doctor.

IV. Alcohol May Reduce Risk

Drinking alcohol is not a risk factor for developing bladder cancer but it may reduce the risk. In any case, the moderate consumption of alcohol is clearly associated with better health and greater longevity. That’s in comparison to either abstaining from alcohol or drinking abusively.

The National Institute on Alcohol Abuse and Alcoholism (NIAAA) had described drinking in moderation. It’s a man consuming four drinks on any day and an average of 14 drinks per week. For women, it’s consuming three drinks in any one day and an average of seven drinks per week.alcohol and bladder cancer

A standard alcoholic drink is:

  • A 12-ounce can or bottle of regular beer
  • A 5-ounce glass of dinner wine
  • A shot (one and one-half ounces) of 80 proof liquor or spirits.

Standard drinks contain equivalent amounts of alcohol. So to a breathalyzer, they’re all the same.

There is no evidence that any particular form of alcoholic beverage confers greater health benefits than any other. That is, neither beer, wine, nor distilled spirits has an  overall health superiority over the others.
