October 30, 2025Colorectal Cancer Symptoms, Stage 4, Metastasis, Young People & Back Pain: The Truth Every New Yorker Must Know
A Lifesaving Guide from Vanguard Gastroenterology, NYC
You're 38. You hit the gym. You grab a green juice on your commute. You feel invincible. Then one day, you see blood in the toilet. You think: “Hemorrhoids.” Six months later, you’re in an oncologist’s office hearing: “Colorectal cancer, stage 4.”
This isn’t a worst-case scenario. It’s the reality we see every month at Vanguard Gastroenterology in Midtown Manhattan. And it’s why we’re sounding the alarm: Colorectal cancer doesn’t care how young, fit, or busy you are.
But here’s the hope: This cancer is 95% preventable. One simple procedure — a colonoscopy — can stop it before it starts. Let’s break down everything you need to know about colorectal cancer symptoms, colorectal cancer stage 4, colorectal cancer metastasis, colorectal cancer in young people, and why colorectal cancer back pain might be your body’s final warning.

What Is Colorectal Cancer and Why It Starts Silently
Colorectal cancer begins as a tiny, harmless polyp — a mushroom-shaped growth on the inner lining of your colon or rectum. Most stay benign. But over 10 to 15 years, a small percentage turn cancerous.
That’s the power of a colonoscopy: We find these polyps long before they become cancer and snip them out during the same 30-minute procedure. No hospital stay. No scars. Just “cancer prevented’.
But most people wait until colorectal cancer symptoms appear. By then, the cancer may have already spread.
Colorectal Cancer Symptoms: Are You Ignoring These Red Flags?
Early colorectal cancer symptoms are often absent or subtle. 50% of patients have zero signs until the disease is advanced. When colorectal cancer symptoms do show up, they’re frequently mistaken for “normal” digestive issues:
- Blood in stool — bright red or dark and tarry
- Persistent bowel changes — diarrhea or constipation lasting more than two weeks
- Feeling of incomplete emptying after using the bathroom
- Unexplained weight loss — clothes suddenly fitting loosely for no reason
- Chronic fatigue — the kind coffee can’t fix
- Abdominal cramping or bloating that won’t go away
But one of the most overlooked colorectal cancer symptoms is…
Colorectal Cancer Back Pain: The Symptom No One Expects
Yes — colorectal cancer back pain is real.
When a tumor grows in the lower rectum or sigmoid colon, it can press on the sacral nerves — the bundle running along your lower spine. The result? Persistent, deep lower back pain that:
- Gets worse when you sit or lie flat
- Doesn’t improve with stretching, Advil, or physical therapy
- Feels like a constant ache in your tailbone or pelvis
This type of colorectal cancer back pain is often misdiagnosed as sciatica or muscle strain — delaying critical diagnosis.
Back pain + any digestive change = urgent evaluation.
Colorectal Cancer in Young People: The Crisis No One Saw Coming
Colorectal cancer in young people is the fastest-rising cancer trend in America. You’re in your 30s. You don’t smoke. You’re not overweight. You’re safe, right?
Wrong.
The numbers are alarming:
- Adults born after 1990 have 2x the colon cancer risk and 4x the rectal cancer risk vs. 1950
- 1 in 5 new cases now occur in people under 55
- Colorectal cancer in young people is now diagnosed in individuals as young as 27 — even those with no family history
Why? Blame the modern lifestyle:
- Ultra-processed diets (daily deli sandwiches, sugary drinks)
- Chronic constipation (most New Yorkers eat less than 10g fiber/day vs. 30g recommended)
- Alcohol (3+ drinks/week doubles risk)
- Vaping (emerging data links to rectal cancer)
- Undiagnosed Lynch syndrome or FAP
The American Cancer Society now says: Start screening at 45. But if you’re younger and have colorectal cancer symptoms or family history, don’t wait.
Colorectal Cancer Stage 4: When Cancer Spreads Beyond the Colon
Colorectal cancer stage 4 is the most advanced form — when the cancer has undergone colorectal cancer metastasis and spread to distant organs.
Where Colorectal Cancer Metastasis Goes (and What It Feels Like)
- Liver: Yellow eyes or skin, swollen belly, nausea
- Lungs: Chronic cough, shortness of breath
- Bones: Severe back or hip pain, spontaneous fractures
- Brain: Headaches, seizures, confusion
When colorectal cancer metastasis reaches the spine or pelvis, colorectal cancer back pain becomes unrelenting — a constant, gnawing ache that wakes you at night.
At colorectal cancer stage 4, treatment focuses on extending life with:
- Immunotherapy (Keytruda — 50% response in MSI-High tumors)
- Targeted therapy (anti-EGFR, anti-VEGF)
- HIPEC surgery (heated chemo in abdomen)
- Liver or lung resection (if isolated)
Survival has doubled in 10 years. But colorectal cancer stage 4 is preventable. One colonoscopy could have stopped this journey before it began.

Frequently Asked Questions (FAQs)
Q2: What is colorectal cancer stage 4?
Colorectal cancer stage 4 means the cancer has spread (colorectal cancer metastasis) to organs like the liver, lungs, or bones. Treatment extends life, but colonoscopy prevents stage 4 entirely.
Q3: What is colorectal cancer metastasis and where does it spread?
Colorectal cancer metastasis occurs when cancer cells travel from the colon to distant organs — most commonly the liver, lungs, bones, or brain. Back pain is common when the spine is involved.
Q4: Can colorectal cancer affect young people?
Yes. Colorectal cancer in young people under 50 is rising rapidly due to diet, lifestyle, and genetics. If you’re under 45 with symptoms or family history, early colonoscopy is critical.
Q5: Why does colorectal cancer cause back pain?
Colorectal cancer back pain occurs when tumors press on sacral nerves or spread to the spine/pelvis, causing constant lower back or tailbone pain unrelieved by rest or medication.
