Alcohol and Colorectal Cancer

There is medical consensus that drinking alcoholic beverages in moderation is not a risk factor for colorectal cancer. The National Cancer Institute,1 the National Library of Medicine,2 the American Society of Clinical Oncology,3 the Memorial Sloan-Kettering Cancer Center,4 and Cancer Research5 have concluded that alcohol (even consumed at high levels) is not a risk factor.

However, the American Cancer Society,6 the Mayo Clinic,7 and the Colorectal Cancer Coalition8 have concluded that "heavy use" or "heavy drinking" may increase the odds of the disease.

Risk factors for Colorectal Cancer

No one knows the exact causes of colorectal cancer. A risk factor is anything that may increase the chance of developing a disease. However, the relationship is not a strong one. A person may have a number of risk factors for colorectal cancer and never develop the disease whereas a person may have no risk factors and get the disease.

There are a number of commonly identified risk factors for colorectal cancer:

Possible Symptoms or Signs of Colorectal Cancer

Colorectal cancer can have any of a number of symptoms. However, in its early stages, there may be no symptoms. Therefore, having regular colorectal cancer screening beginning at age 50 is important.

Symptoms of colorectal cancer can include any of the following:

Having any of these symptoms does not mean that a person has colorectal cancer. However, they should be discussed with a doctor if they last more than two weeks.

Drinking in Moderation is Beneficial

Drinking alcohol in moderation is not a risk factor for developing colorectal cancer. However, the moderate consumption of alcohol is clearly associated with better health and greater longevity than is either abstaining from alcohol or drinking abusively.

Drinking in moderation has been described by the National Institute on Alcohol Abuse and Alcoholism (NIAAA) as a man consuming four drinks on any day and an average of 14 drinks per week. For women, it is consuming three drinks in any one day and an average of seven drinks per week.

A standard alcoholic drink is:

Standard drinks contain equivalent amounts of alcohol. To a breathalyzer, they're all the same.

There is no evidence that any particular form of alcoholic beverage (beer, wine, or distilled spirits) confers greater health benefits than any other.
