Too Young for Rectal Cancer? A Growing Number of Americans Aren’t
What decades of screening got right for older adults, and what younger generations are missing.
For years, rectal cancer carried an unspoken label.
It was something that happened later. Something tied to aging, retirement, and routine screenings that began after fifty. Younger bodies, we believed, were largely spared.
The numbers no longer agree.
In the United States, rectal cancer remains a serious disease among older adults, but a quieter, more unsettling trend has emerged: rates among adults under 50 are rising, steadily and consistently. This is not speculation. It is documented, measured, and confirmed by national cancer data.
What Data Tells Us..
Rectal cancer is part of the larger group known as colorectal cancers, which include cancers of the colon and rectum. Together, they form one of the most common and deadly cancer categories in the country.
According to the American Cancer Society:
- Nearly 50,000 Americans are expected to be diagnosed with rectal cancer in 2026
- When combined with colon cancer, over 150,000 new colorectal cancer cases occur annually in the U.S.
- Colorectal cancer remains the third most commonly diagnosed cancer and a leading cause of cancer-related death
For decades, most of these cases occurred in people over 60. That pattern shaped screening rules, public awareness, and even how symptoms were interpreted.
And for older adults, screening worked.
***
Among Americans aged 65 and older, rates of colorectal cancer have declined significantly since the mid-1980s. This is largely credited to routine screening, early detection, and the removal of precancerous polyps.
Today:
- About 70 percent of U.S. adults aged 50–75 are up to date with colorectal cancer screening, according to the CDC
- Early-stage detection has improved survival rates dramatically
- Many cancers are prevented entirely before they ever form
This is what prevention looks like when it works.
But prevention has an age boundary, and cancer did not respect it.
The Shift No One Expected: Rising Rates Under 50
While rates fall in older adults, they are rising in younger ones.
The American Cancer Society reports that colorectal cancer rates in adults under 50 increased by nearly 3 percent per year between 2013 and 2022. Rectal cancer makes up a large share of these early-onset cases.
Researchers now project that by 2030, roughly one in four rectal cancer cases may occur in people younger than traditional screening age.
That is not a minor trend. That is a generational shift.
Even more concerning, many younger patients:
- Have no family history of colorectal cancer
- Do not carry known genetic syndromes
- Are otherwise considered low risk
Which means warning signs are often missed, delayed, or dismissed.
The Symptoms Young People Are Told to Ignore
In younger adults, rectal cancer is rarely found through screening. It is found through symptoms.
Yet those symptoms are frequently brushed off as stress, diet, hemorrhoids, or being “too young for something serious.”
Studies published in major U.S. medical journals show that rectal bleeding in adults under 50 is strongly associated with colorectal cancer, but diagnostic delays are common.
Symptoms that deserve attention at any age include:
- Rectal bleeding or blood in stool
- Persistent changes in bowel habits
- Narrow stools or a feeling of incomplete emptying
- Unexplained weight loss
- Ongoing abdominal discomfort or fatigue
Ignoring these signs does not make them harmless. It only makes diagnosis later.
Why This Matters Now, Not Later
Rectal cancer does not become dangerous overnight. It develops over time, often from precancerous growths that could be treated if found early.
The problem is not that younger adults are doomed.
The problem is that they are not looking, and often no one is looking for them.
Awareness is not fear. Awareness is protection.
How to Take Care of Yourself, Practically and Honestly
You do not need to panic. You do need to pay attention.
- If you are 45 or older, follow current U.S. screening guidelines
- If you are under 45 with persistent symptoms, do not wait for permission to be taken seriously
- Talk openly with a healthcare provider about symptoms, not just age
- Reduce known risk factors where possible: stay active, eat fiber-rich foods, avoid alcohol, avoid smoking, maintain a healthy weight
Early action saves lives. Late dismissal costs them.
One Last Thing
Rectal cancer is still more common in older adults, and screening has saved countless lives there. But the data is clear: younger adults are no longer exempt.
This is not a reason to live in fear.
It is a reason to live informed.
Cancer does not check birth years.
Neither should awareness.

Elizabeth Smart: From Captivity to Courage
The night Elizabeth Smart disappeared did not announce itself with drama. It arrived quietly, the way danger often does. In the early hours of June 5, 2002, while a Salt Lake City home slept, a man entered through an open window. He moved with confidence, not haste. He carried a knife. He went first to a child’s bed.

The Angry Man in Your House
"If you grow up with an angry man in your house, there will always be an angry man in your house" This statement has caused plenty of controversy online, people say its a statement that blames victims while also undermining those who break traumatic cycles to form health relationships... but if I'm honest now that I'm in my 30s it makes more sense to me than ever, and I'd argue that its not just about fathers and uncles.

Alexander the Great — Part 4: Death, Division, and an Immortal Legacy
Babylon had become Alexander’s administrative center and was intended to be the capital of his vast empire. The city was strategically located and symbolized the blending of Eastern and Western cultures — a key vision for Alexander. He planned new military campaigns, including a possible invasion of Arabia, and began organizing naval expeditions. However, after days of heavy drinking and planning, Alexander suddenly fell ill. Ancient sources describe him suffering from fever, weakness, and the gradual loss of speech. Within roughly ten days, he died. The exact cause of Alexander’s death remains one of history’s great mysteries. Some historians suggest malaria, typhoid fever, or another disease common in the region. Others believe complications from old battle wounds and exhaustion contributed to his decline. There have also been theories of poisoning, though evidence remains inconclusive. Whatever the cause, the sudden loss of such a powerful ruler left a massive empire without clear leadership. Alexander had not named a definitive successor. When asked on his deathbed who should inherit the empire, he reportedly said, “To the strongest.” Whether this statement is accurate or not, it reflected the reality that followed. His generals, known as the Diadochi, began competing for control. At first, they attempted to maintain unity by ruling in the name of Alexander’s unborn son and his half-brother, but tensions quickly escalated into open conflict. The Wars of the Diadochi lasted for decades. Former allies turned against each other, carving the empire into separate kingdoms. Ptolemy took control of Egypt and established a dynasty that would rule for nearly three centuries. Seleucus gained vast territories in the east, forming the Seleucid Empire. Antigonus and his descendants controlled parts of Asia Minor and Greece. Instead of a single unified empire, Alexander’s conquests transformed into a network of Hellenistic states. Despite political fragmentation, Alexander’s cultural influence continued to grow. His campaigns had spread Greek language, art, and philosophy across Asia and the Middle East. This fusion of Greek and local traditions created what historians call the Hellenistic world. Cities founded by Alexander, especially Alexandria in Egypt, became centers of learning and innovation. The Library of Alexandria housed thousands of scrolls and attracted scholars from across the known world. Advances in science, mathematics, astronomy, and medicine flourished during this period. Alexander’s leadership style also left a lasting impact. He encouraged cultural integration, adopting aspects of Persian dress and customs and promoting marriages between his soldiers and local populations. Though some of his Macedonian troops resisted these policies, they contributed to the blending of cultures that defined the Hellenistic age. Trade routes expanded, connecting Mediterranean markets with those in India and Central Asia. Ideas and technologies traveled along these routes, shaping civilizations for centuries. Over time, Alexander became more than a historical figure; he became a legend. Stories about his life were retold in many cultures, each adding its own interpretations. In Greek and Roman traditions, he was portrayed as a heroic conqueror and brilliant strategist. In Persian and Middle Eastern tales, he appeared as a complex ruler, sometimes wise and sometimes destructive. In South Asian folklore, he was remembered as a powerful but distant invader. These varied portrayals demonstrate how deeply his story resonated across different societies. Historians continue to debate Alexander’s character. Some view him as a visionary who sought to unite diverse peoples under a shared culture. Others see him as an ambitious conqueror driven by personal glory. He could be generous and respectful toward defeated enemies, as seen with King Porus, but also ruthless when facing resistance. His execution of close companions, such as the general Parmenion, and his increasing demand for divine honors reveal the pressures and changes he experienced as his empire grew. What is certain is that Alexander transformed the ancient world in an extraordinarily short time. In little more than a decade, he dismantled one of the largest empires in history and replaced it with a new cultural and political landscape. His campaigns opened routes for trade and communication between East and West, influencing the spread of ideas that would shape future civilizations. Even the rise of the Roman Empire was indirectly influenced by the Hellenistic states that emerged from Alexander’s conquests. Alexander’s tomb itself became part of the mystery surrounding his legacy. After his death, his body was placed in a golden sarcophagus and eventually transported to Egypt. It was displayed in Alexandria, where later rulers and visitors reportedly paid their respects. Over time, however, the exact location of his tomb was lost. Despite numerous searches, it has never been definitively found, adding another layer to the legend of the man who conquered so much yet left behind unanswered questions. Part 4 of Alexander’s story shows that while his life ended abruptly, his influence did not. His empire fractured, but his vision of cultural connection endured. He remains a symbol of ambition, leadership, and the complexities of power. Alexander the Great’s journey from a young Macedonian prince to the ruler of a vast empire continues to inspire fascination. His story is not only about conquest but also about the spread of ideas, the blending of cultures, and the enduring impact one individual can have on the course of history.

I feel when Farrah Fawcett had cancer, many were advocating for early detection. As I myself age I am getting more worried about potential health issues. Good article
