Excluding skin cancers, colorectal cancer is the third most common cancer in women and men in the United States. The American Cancer Society’s estimates for the number of colorectal cancers in the United States for 2023 are:

• 106,970 new cases of colon cancer
• 46,050 new cases of rectal cancer

The rate of colorectal cancer diagnoses has dropped annually since the mid-1980s, largely because more people are getting screened and changing lifestyle-related risk factors.

Colorectal Cancer is Rising Among the Young

From 2011 to 2019, colorectal cancer incidence rates dropped by about one percent annually. However, this downward trend is mostly in older adults. For those under 50, rates have been increasing by one to two percent each year since the mid-1990s.

Colorectal cancer is a significant health concern worldwide, accounting for many cancer-related deaths. As researchers continue to investigate potential preventive strategies, one intriguing area of study is aspirin.

While we lack sufficient data to recommend aspirin to reduce colorectal cancer risk routinely, a new study is encouraging.

Aspirin, a widely available non-steroidal anti-inflammatory drug (NSAID), has been the subject of numerous studies examining its potential role in reducing the risk of colorectal cancer.

This essay delves into the relationship between aspirin use and the risk of colorectal cancer, exploring the evidence, mechanisms, and potential benefits of this medication.

Aspirin and Colorectal Cancer — Background

Multiple studies have suggested a potential link between aspirin use and a reduced risk of developing colorectal cancer. The evidence originates from observational studies and randomized controlled trials.

First, observational studies (such as the Nurses’ Health Study and the Health Professionals Follow-up Study) show a consistent association between long-term aspirin use and a reduced incidence of colorectal cancer.

Second, a meta-analysis published in The Lancet in 2010 found a one-quarter (24 percent) reduction in colorectal cancer incidence among individuals who took aspirin regularly.

How Might Aspirin Reduce Colorectal Cancer Risk?

We have not yet fully elucidated the mechanisms by which aspirin might reduce colorectal cancer risk. There are likely several biological pathways.

For example, aspirin exerts anti-inflammatory effects by blocking the cyclooxygenase (COX) enzymes, especially COX-1 and -2. These enzymes are critical to prostaglandin production, substances known to promote inflammation and cancer development.

Aspirin inhibits COX enzymes, dropping prostaglandin production and attenuating the inflammatory response.

Aspirin — Cancer and Cardiovascular Benefits?

While the evidence suggests a potential protective effect of aspirin against colorectal cancer, it is important to consider the benefits and the potential risks associated with its use.

Aside from reducing the incidence of colorectal cancer, aspirin has also been linked to a lower risk of other gastrointestinal cancers, including the esophagus, stomach, and pancreas.

Additionally, aspirin has well-established cardiovascular benefits, including preventing heart attacks and strokes, further enhancing its potential value.

However, it is important to acknowledge the potential risks of aspirin use, such as gastrointestinal bleeding and hemorrhagic stroke. These risks tend to increase with higher doses and long-term use.

Therefore, individuals considering aspirin for colorectal cancer prevention should consult their healthcare providers to evaluate their risk factors and discuss the potential benefits and risks.

Colon Polyps and Adenomas

A colon polyp is a small clump of cells that forms on the colon’s lining. Most colon polyps are harmless. But over time, some colon polyps can develop into colon cancer. Colon cancer can be fatal when found in its later stages.

Anybody can develop colon polyps. The risk is higher for those 50 or older. Smokers and overweight individuals also have a higher risk. Those with a personal or family history of colon polyps or colon cancer also are at higher risk of developing a polyp.

Colon polyps don’t usually cause symptoms. It’s important to have regular screening tests because the doctor can usually remove early colon polyps safely and completely. The best prevention for colon cancer is regular screening for and removing polyps.

Adenomas are non-cancerous tumors. Tubular adenomas are pre-cancerous polyps in your colon (or rectum), typically found during colonoscopies. Such polyps are your body’s early warning system for colorectal cancer. While approximately half of us will develop tubular adenomas, less than one in ten tubular adenomas, become cancer.

Aspirin and Colorectal Cancer — A New Study

Aspirin is a compelling research area in the context of colorectal cancer risk reduction. A new study assessed the association between regular aspirin or NSAID (non-steroidal anti-inflammatory drugs such as ibuprofen) use at least twice weekly with the risk of developing early-onset adenoma.

A new study demonstrates the following:

Regular use of aspirin or other nonsteroidal anti-inflammatory drugs was associated with a lower risk of early-onset conventional and advanced adenomas.

The researchers explain that aspirin could be an effective strategy in preventing early-onset colorectal cancer.

One of the study authors, Dr. Cassandra Fritz of Washington University (USA), offers a “15 percent reduction for all adenomas and a one-third drop for those with more concerning forms of adenoma.

The analysis focused on data from the Nurses’ Health Study II. The study included more than 32,000 women with at least one colonoscopy before age 50 (1991–2015).

For the clinicians amongst you: High-risk adenomas included those at least one centimeter with tubulovillous/villous histology or high-grade dysplasia or at least three adenomas.

Aspirin Risks: The Drug is Not for Everyone

For selected individuals, daily aspirin is helpful to lower heart attack, clot-related stroke, and other blood flow risks in patients with cardiovascular disease or who have already had a heart attack or stroke. Many medical professionals prescribe aspirin for these uses.

There may be a benefit to daily aspirin use if you have some kind of heart or blood vessel disease or if you have poor blood flow to the brain. However, long-term aspirin use risks may be greater than the benefits if there are no signs of, or risk factors for, heart or blood vessel disease.

The US Food and Drug Administration (FDA) reminds us that every prescription and over-the-counter medication has risks and benefits — even aspirin, a common medicine. Aspirin can cause serious toxicities, such as brain or stomach bleeding and kidney failure.

No medicine is completely safe. By carefully reviewing many factors, your health professional can help you make the best choice.

Please Don’t Forget Colorectal Screening

Colorectal cancer screening plays a crucial role in the early detection and prevention of one of the most common types of cancer worldwide.

Colorectal cancer is highly treatable when caught early. However, it often develops without noticeable symptoms in its initial stages, underscoring the significance of regular screening.

Screening for colorectal cancer is recommended for both men and women starting at the age of 45 or earlier for individuals with a family history of the disease or other risk factors.

Various screening methods are available, including colonoscopy, sigmoidoscopy, fecal occult blood tests (FOBT), and fecal immunochemical tests (FIT).

Colorectal Cancer Screening Benefits

These screening tests help identify precancerous polyps or early-stage cancers that may not yet be causing symptoms. Detecting and removing these abnormal growths during screening can significantly reduce the risk of developing colorectal cancer.

Regular colorectal cancer screening has several important benefits. Firstly, it reduces mortality rates by detecting cancer early when it is more treatable. Early detection often leads to less invasive treatment options, higher survival rates, and better patient outcomes.

Secondly, screening can help identify and remove polyps before they become cancerous, preventing colorectal cancer altogether. This observation highlights the preventive aspect of screening, as it can potentially eliminate or catch the disease at its most treatable stage.

Lastly, screening can provide peace of mind for individuals by assuring them that their colorectal health is being monitored and any issues can be addressed promptly.

Regular screening, combined with a healthy lifestyle that includes a balanced diet, regular exercise, and avoidance of known risk factors such as smoking and excessive alcohol consumption, significantly contributes to the overall prevention and early detection of colorectal cancer.

Key points — Unveiling the Power of Aspirin: Game-Changer for Colon Cancer Prevention?

Question. Does aspirin have the potential to be a game changer for colon cancer prevention?

Findings. A new study shows that the regular use of aspirin or other nonsteroidal anti-inflammatory drugs is associated with a lower risk of early-onset conventional and advanced adenomas.

Meaning. While confirmatory research is needed, the one-seventh (15 percent) reduction with aspirin/NSAIDS in early-onset adenoma — and particularly for the quite substantial one-third risk-reduction in advanced adenoma with advanced histology, we need to think about a precision-based chemoprevention strategy for early-onset precursors of colorectal cancer.

This study does not give us high-level evidence to recommend aspirin for all. Individuals at high risk for colorectal cancer should consult an expert healthcare provider. Of course, screening remains a cornerstone of reducing our risk of dying from colorectal cancer.

The US Food and Drug Administration reminds us that if you use aspirin daily to prevent a heart attack, stroke, or any use not listed on the label — without guidance from your health professional — you could be doing your body more harm than good.

Doctors should no longer prescribe daily doses of aspiring to pre-CVD patients because of the increased risk of bleeding, a risk that increases with age.

We’ve known for a long time that aspirin reduces risk for those who’ve already experienced a heart attack or stroke, and logic and research supported the idea that administering aspirin to a patient prior to a cardiac event would reduce the likelihood and/or severity of CVD or stroke.

Simply put, aspirin works by thinning your blood (an anticoagulant), making the blood less likely to form clots and thinner blood requires less effort to circulate, so the heart doesn’t have to pump as hard. Benefits were seen to extend not only to CVD but also to the incidence of strokes.

Now, the U.S. Preventive Services Task Force, an independent panel of experts, has just released an updated draft recommendation that says most adults should not take aspirin to prevent first heart attacks or strokes.

The newly updated guidance recommends that adults in their 40s and 50s only take aspirin as a preventive measure if their doctors determine they are at higher risk for heart disease and that aspirin may lower the risk without significant risk of bleeding. Previous guidance didn’t address anyone younger than 50.

People ages 60 or older are now advised not to start taking aspirin to prevent first heart attacks or strokes.

So what has changed?

The timing of the new advisory couldn’t have been worse. It follows on the heels of an Israeli study and this study that points to the efficacy of aspirin for treating severe Covid and mounting evidence that a daily dose of aspirin may reduce the risk of infection from the virus.

The new advisory is seen by many as an attempt to smear aspirin as a cheap and effective treatment for Covid, forcing people instead to opt for more costly treatment options. They cite the recent examples of Ivermectin and Hydroxychloroquine to support the pattern, but mistakenly so, as data shows neither drug to be effective.

Aspirin does however appear to reduce the risk of severe Covid for some patients.

Conspiracies, baseless or otherwise, aside, the new advisory is still under review, pending input from providers. We have known for many years that aspirin poses a risk for bleeding in some individuals and that this risk increases for the elderly. Every doctor that prescribes aspirin takes these risk factors into consideration when treating a patient.

Aspirin remains one of the safest and well-tolerated drugs we have at our disposal. Poll any doctor over the age of 40 and you’ll find many drink an aspirin each day, that’s how entrenched the belief in the drug has become and it is available without prescription in almost every country on the planet as an over-the-counter (OTC) medicine.

So how should you as a patient, respond to the latest advice? If you do fall into the new categories (60+) defined as high risk, discuss your medication regimen with your doctor. Patients should be aware that these advisories apply to patients that have not yet experienced CVD or suffered a stroke.

Doctors recommend daily low-dose aspirin for many patients who already have had a heart attack or stroke and the task force guidance does not change that advice.

If you’re self-medicating with aspirin, there are a few things you should consider.

• Don’t simply start using aspirin because you’ve reached a certain age and if you’re over 70, definitely don’t take aspirin unless advised by your doctor.
• If you’re a candidate for CVD, in other words, if you smoke and drink heavily, if you have elevated blood pressure, high BMI, or suffer from obesity and have a family history of CVD, aspirin may benefit you, but again, a doctor is best placed to advise you.
• Aspirin will thin your blood, but won’t address the contributing factors that result in CVD. It won’t drop your blood pressure, lower your cholesterol or help you lose weight. Eventually, these factors will negate any positive effect aspirin may have on your heart.
• You may, inadvertently be compromising your health if you are over 50 and risk ulcers and bleeding. Your doctor is best qualified to properly assess this risk.

Dr. Erin Michos, an associate director of preventive cardiology at the Johns Hopkins Ciccarone Center for the Prevention of Heart Disease, who isn’t part of the task force, had this to say about widely known recommendations that endorsed daily aspirin use for decades;

“We’ve gotten a lot better with other medical therapies, and the aspirin recommendations were developed during trials conducted before statins were widely used and smoking was more widespread. The incremental benefit of aspirin in contemporary medicine does not provide as strong of a benefit for primary prevention as it once would.”

There is no magic medication for negating your risk of heart disease and stroke, and aspirin, although beneficial, won’t make you bulletproof. You will need a multifaceted approach that includes a healthy diet and regular exercise, and yes, perhaps an aspirin a day. Talk to your doctor.

She was only 26 weeks pregnant, and her life was in imminent jeopardy. The doctors recommended immediate delivery. Her baby survived the emergency c section but spent the first three months in the neonatal care unit.

Now that she is pregnant again. She wants to know how to reduce her risk.

Reducing the rate of preeclampsia in pregnant women through daily low-dose aspirin in high-risk patients may save lives and reduce the risk of poor pregnancy outcomes.

The American College of Obstetricians and Gynecologists (ACOG) and the US Preventative Services Task Force (USPSTF) are two leading medical associations that recommend daily low-dose aspirin for women with an increased risk of developing preeclampsia during pregnancy. Low-dose aspirin is an inexpensive and easily-accessible medication that lowers the risk of preeclampsia in high-risk women.

What is preeclampsia?

Preeclampsia is a common blood pressure disorder affecting 2–8% of pregnancies worldwide. Preeclampsia is the cause of 12% of maternal deaths. The USPSTF reports one-third of severe obstetric complications and 15% of preterm births in the United States arise from preeclampsia.

Preeclampsia is a leading cause of US maternal deaths, severe maternal morbidity, maternal intensive care admissions, cesarean section, and prematurity. Each year, preeclampsia and other pregnancy blood pressure disorders cause over 70,000 maternal and 500,000 fetal deaths worldwide.

Preeclampsia is diagnosed when high blood pressure occurs after the 20th week of pregnancy in conjunction with other signs and symptoms. Symptoms include headache, right upper abdominal pain, or visual changes. Signs include swelling, weight gain, urine protein leakage, or fluid retention in the lungs. Lab work may show low platelets, poor kidney function, or an elevation in liver enzymes.

Preeclampsia risk factors include:

• Previous pregnancy complicated by preeclampsia
• Chronic hypertension
• Pregestational diabetes mellitus
• Antiphospholipid syndrome
• Obesity
• Advanced maternal age
• Young maternal age
• Racial disparities — Black women are at increased risk of developing pregnancy-related blood pressure complications.
• Underlying kidney disease
• Pregnancies from assisted reproductive technologies

Low-dose aspirin reduces the risk of preeclampsia

The USPSTF and ACOG recommend the use of low-dose aspirin for women at risk of developing preeclampsia. Any pregnant woman with one or more of the above risk factors may benefit from this low-cost, low-risk intervention to reduce their pregnancy hypertension risk. 

The current clinical trial data shows daily low-dose aspirin reduces the risk of preeclampsia by 24%. The recommendation is to begin low-dose aspirin (81 mg/day) between 12 weeks and 28 weeks of gestation and continue daily until delivery.

The studies also show aspirin use in pregnancy is safe with a low risk to mom and baby. A USPSTF meta-analysis did not show aspirin increased the risk for bleeding complications such as placental abruption, postpartum hemorrhage, or fetal intracranial bleeding. 

The underlying cause of preeclampsia is unknown, but we know it is a complex multisystem inflammatory syndrome. Low-dose aspirin has anti-inflammatory, antiangiogenesis, and antiplatelet properties. These unique features may account for the beneficial effects on placenta development and placenta perfusion. 

An aspirin a day keeps preeclampsia away

Scientists continue to study preeclampsia. Researchers are looking to understand its origins and triggers. Medical studies attempt to find reliable biomarkers and improve diagnostic tools.

In the meantime, we can reduce the risk of preeclampsia by encouraging the daily low-dose aspirin in women who have an increased risk for high blood pressure in pregnancy.
