Colon cancer has long been considered a disease that primarily affects older adults. However, recent studies have shown a concerning rise in the incidence of colon cancer in people below the age of 50.

While the exact causes of this trend are not yet fully understood, there is evidence to suggest that certain drugs may be contributing to the development of colon cancer in younger populations. Here is a comprehensive list of drugs that have been linked to an increased risk of colon cancer in people under the age of 50.

1. Nonsteroidal anti-inflammatory drugs (NSAIDs)

NSAIDs are commonly used to treat pain, inflammation, and fever, and are available both over-the-counter and in prescription-strength formulations.

While these drugs have been shown to have a number of health benefits, such as reducing the risk of heart attack and stroke, they have also been linked to an increased risk of colon cancer in younger populations.

Research has shown that regular use of NSAIDs, particularly at high doses, can damage the lining of the colon and increase the risk of cancerous growths.

In one study of over 85,000 women, those who regularly took NSAIDs were found to have a 40% increased risk of colon cancer compared to those who did not use the drugs.

2. Antibiotics

Antibiotics are prescribed to treat bacterial infections, but they can also have unintended effects on the body’s microbiome, the complex ecosystem of bacteria that exists in the gut.

This can lead to changes in the gut environment that promote the growth of cancerous cells.

A study published in the journal Gut found that people who had taken antibiotics in the past were significantly more likely to develop colon cancer than those who had not.

The risk was most pronounced in those who had taken multiple rounds of antibiotics or who had taken the drugs at a young age.

3. Hormone replacement therapy (HRT)

HRT is used to alleviate the symptoms of menopause, such as hot flashes and vaginal dryness. However, research has shown that long-term use of HRT can increase the risk of a number of health problems, including breast cancer, stroke, and blood clots.

There is also evidence to suggest that HRT may contribute to the development of colon cancer in younger populations.

A study published in the Journal of the National Cancer Institute found that women who had used HRT for more than 10 years were at a significantly increased risk of colon cancer compared to those who had not used the drugs.

The risk was highest among women who had used estrogen-only HRT.

4. Accutane

Accutane, also known as isotretinoin, is a powerful medication used to treat severe acne. While the drug can be highly effective in clearing up acne, it has been linked to a number of serious side effects, including an increased risk of colon cancer.

In one study of over 1,000 patients who had taken Accutane, researchers found that the drug was associated with a higher risk of colorectal adenomas, a type of growth that can lead to colon cancer.

The risk was highest among patients who had taken the drug at a young age.

5. Proton pump inhibitors (PPIs)

PPIs are commonly used to treat acid reflux and other gastrointestinal conditions. While the drugs are generally considered safe and effective, there is growing concern that they may contribute to the development of colon cancer in younger populations.

One study published in the journal BioMed Research International found that use of PPIs was associated with an increased risk of colon cancer in people under the age of 50. The risk was highest among those who had taken the drugs for more than a year.

6. Antipsychotic medications

Antipsychotic medications are used to treat a variety of mental health conditions, including schizophrenia and bipolar disorder. However, these drugs have been linked to a number of serious side effects, including an increased risk of colon cancer.

In one study of over 100,000 patients who had taken antipsychotic medications, researchers found that the drugs were associated with a higher risk of colon cancer.

The risk was highest among patients who had taken the drugs at a young age or who had taken them for more than a year.

7. Metformin

Metformin is a commonly prescribed medication used to treat type 2 diabetes. While the drug is generally considered safe and effective, there is some evidence to suggest that it may contribute to the development of colon cancer in younger populations.

A study published in the Journal of the American Medical Association found that regular use of metformin was associated with an increased risk of colon cancer in patients under the age of 50.

The risk was highest among those who had taken the drug for more than five years.

8. Acid-reducing medications

Acid-reducing medications, such as histamine-2 receptor blockers (H2 blockers) and proton pump inhibitors (PPIs), are commonly used to treat acid reflux, ulcers, and other gastrointestinal conditions.

While these drugs can be highly effective at relieving symptoms, they have been linked to an increased risk of colon cancer in younger populations.

One study published in the journal Alimentary Pharmacology and Therapeutics found that use of H2 blockers was associated with an increased risk of colon cancer in people under the age of 50.

The risk was highest among those who had taken the drugs for more than a year. Another study published in the journal Gut found that use of PPIs was associated with an increased risk of colon cancer in people under the age of 50.

9. Anti-diabetic medications

Anti-diabetic medications, such as sulfonylureas and insulin, are commonly used to treat type 2 diabetes.

While these drugs can be highly effective at reducing blood sugar levels, there is evidence to suggest that they may contribute to the development of colon cancer in younger populations.

A study published in the Journal of Clinical Oncology found that use of sulfonylureas was associated with an increased risk of colon cancer in people under the age of 50. The risk was highest among those who had taken the drugs for more than five years.

Another study published in the same journal found that use of insulin was associated with an increased risk of colon cancer in people under the age of 50.

10. Statins

Statins are commonly used to lower cholesterol and reduce the risk of heart disease.

While these drugs have been shown to have a number of health benefits, there is some evidence to suggest that they may contribute to the development of colon cancer in younger populations.

A study published in the journal Cancer Epidemiology, Biomarkers and Prevention found that regular use of statins was associated with an increased risk of colon cancer in people under the age of 50.

The risk was highest among those who had taken the drugs for more than five years.

Conclusion

While the exact causes of the rise in colon cancer among younger populations are not yet fully understood, there is evidence to suggest that certain drugs may be contributing to the trend.

If you are taking any of the drugs listed above, it is important to talk to your healthcare provider about the potential risks and benefits of the medication. Your provider can help you weigh the risks and benefits of your treatment options and develop a plan that is right for you.
