Beer And Radiation: What's Safe To Drink?

Drinking alcohol after radiation treatment is generally not recommended by doctors, as it can cause irritation and discomfort, especially if the treatment is focused on the head, neck, throat, oesophagus, or stomach. Alcohol can also interfere with chemotherapy drugs and increase their side effects, as both alcohol and drugs are metabolised by the liver. Excessive drinking is associated with weight gain, which is a significant risk factor for cancer. However, some studies suggest that drinking wine may promote heart health.

Alcohol can irritate the stomach lining, which is also irritated by radiation therapy

Radiation therapy can irritate the lining of the bowel or stomach and affect the way the bowel works. These changes are usually temporary, but for some people, they can be permanent and negatively impact their quality of life. Radiation therapy can cause inflammation and swelling in the lining of the rectum, known as radiation proctitis. Symptoms may include blood and mucus in bowel movements, discomfort when opening the bowels, and the urgent and frequent need to empty the bowels.

Alcohol can irritate the stomach lining in a similar way to radiation therapy. It can increase the amount of acid in the stomach, causing gastritis, which is inflammation of the stomach lining. Alcoholic gastritis is caused by drinking too much, too often, and it can irritate and erode the stomach lining. This can trigger gastritis symptoms such as a burning ache in the stomach, constant pain between the navel and ribs, belching, hiccupping, and a bloated feeling in the stomach. If left untreated, gastritis can lead to serious problems such as anemia, peptic ulcers, gastric polyps, and stomach tumors.

Therefore, consuming alcohol after radiation therapy can potentially irritate the stomach lining further and exacerbate any side effects from the treatment. Alcohol can also interfere with the healthy production of blood cells and platelets and add to the sedative effects of medications taken to control pain or nausea.

It is important to consult a healthcare professional for advice on alcohol consumption during and after radiation therapy, as individual circumstances may vary.

Alcohol interferes with the healthy production of blood cells and platelets in the bone marrow

Alcohol has a detrimental impact on the healthy production of blood cells and platelets in the bone marrow. It interferes with the bone marrow's ability to produce white and red blood cells, leaving individuals fatigued, weak, and susceptible to infections. White blood cells are critical for the body's defence against infections, while red blood cells are essential for energy and oxygen transport.

Additionally, excessive alcohol consumption can lead to the destruction of both types of blood cells. The bone marrow also produces platelets, which are responsible for blood clotting. Alcohol use can affect the shape and function of platelets, causing a decrease in their count, known as thrombocytopenia. This can put individuals at risk for excessive bleeding and strokes.

The toxic effects of alcohol on the bone marrow are dose-dependent, and severe impairment of blood cell production usually occurs in individuals with severe alcoholism. Alcohol can cause characteristic structural abnormalities in blood cell precursors, resulting in non-functional mature blood cells. As a result, individuals may suffer from moderate anemia, reduced white blood cell counts, and a decrease in platelet numbers.

Abstaining from alcohol can reverse the negative effects on bone marrow function and blood cell production. Seeking proper treatment for alcohol use disorder is crucial to restore healthy blood cell and platelet production in the bone marrow.

Drinking alcohol during cancer treatment can worsen side effects and interact with medication

Alcohol can negatively impact cancer treatment in several ways. Firstly, it can interfere with the healthy production of white blood cells, red blood cells, and platelets in the bone marrow, which is particularly detrimental for patients with blood and marrow cancers, as their bone marrow function may already be compromised. Alcohol also acts as a sedative, exacerbating fatigue and interacting with pain or nausea medication. It can irritate the stomach lining and gastrointestinal tract, worsening the side effects of radiation therapy or chemotherapy. Furthermore, since chemotherapy drugs are excreted through the liver, drinking alcohol can cause additional stress and potential damage to this organ.

For these reasons, it is generally recommended to avoid drinking during cancer treatment, especially for those undergoing radiation to the head, neck, throat, esophagus, or stomach, as alcohol can cause physical irritation and discomfort in these areas. However, for those receiving radiation to other parts of the body, drinking in moderation may be acceptable. It is important to discuss alcohol consumption with your doctor, as stopping alcohol abruptly can also lead to serious health effects.

Alcohol consumption is associated with a higher risk of developing several types of cancer

While it is not strictly impossible to drink beer after radiation therapy, it is generally advised against. Alcohol can cause irritation to the stomach and gastrointestinal tract, similar to the irritation caused by radiation therapy and chemotherapy. It can also worsen oral mucositis or mouth sores.

In addition, alcohol can interfere with the healthy production of white blood cells, red blood cells, and platelets in the bone marrow. For patients with blood and bone marrow cancers, this can be particularly harmful. Alcohol also puts additional strain on the liver, which is already working hard to process the toxins from chemotherapy.

For these reasons, it is recommended that you consult your doctor about alcohol consumption during cancer treatment. They will likely advise that you limit your alcohol intake or abstain completely, especially if you are undergoing radiation to the head, neck, throat, oesophagus, or stomach.

Alcohol Consumption and Cancer Risk

The types of cancer most strongly associated with alcohol consumption include cancers of the oral cavity, pharynx, oesophagus, and larynx. There is also a statistically significant increase in risk for cancers of the stomach, colon, rectum, liver, female breast, and ovaries. Even at relatively low levels of alcohol consumption (two standard drinks per day), the risk of these cancers is significantly increased.

In addition, concurrent tobacco use, which is common among drinkers, enhances alcohol's effects on the risk of cancers of the upper digestive and respiratory tract. The combination of alcohol and tobacco increases the risk of these cancers more than would be expected from simply adding the individual risks of each substance.

While some studies have suggested that moderate alcohol consumption may have health benefits, such as a reduced risk of certain types of heart disease and stroke, any potential benefits are likely outweighed by the increased risk of cancer and other negative health effects. The optimal number of drinks to consume per day to minimise the overall risk to health is zero.

Therefore, it is important to limit or eliminate alcohol consumption, especially for those undergoing cancer treatment or those who are at a higher risk of developing alcohol-associated cancers.

Beer may reduce radiation-induced chromosome aberrations in human lymphocytes

Radiation therapy for cancer often requires patients to make changes to their daily routines and lifestyle habits. It is generally recommended that patients limit alcohol intake during cancer treatment, before, during, and after. This is because alcohol can interfere with the healthy production of white blood cells, red blood cells, and platelets.

However, a study by Manami Monobe et al. found that drinking beer may reduce radiation-induced chromosome aberrations in human lymphocytes. The study, published in the Journal of Radiation Research, investigated the effects of beer drinking on radiation-induced chromosome aberrations in blood lymphocytes. Human blood was collected before and after drinking a 700 ml beer and was then irradiated with X-rays or carbon ions. The results showed that the relation between the radiation dose and the aberration frequencies was significantly lower for lymphocytes collected 3 hours after beer drinking than those before drinking. A decrease in dicentric formation was detected as early as 30 minutes after beer drinking and lasted for at least 4.5 hours.

The study concluded that beer could contain non-ethanol elements that reduce chromosome damage induced by high-LET radiation. Beta-pseudouridine, a component of beer, was found to reduce radiation-induced chromosome aberrations. Further studies are needed to fully understand the mechanisms involved and the potential benefits of beer consumption during radiation therapy.
