Colorectal Cancer: Quick Facts and Why Exercise Matters
Colorectal cancer is the third most common cancer in the UK, but many people still think it only affects the elderly. The truth is, it can show up in anyone over 40, and catching it early makes a huge difference. In this guide we’ll break down the main signs, explain how screening works, and show you simple ways to lower your odds – especially by staying active.
Spotting the Warning Signs
First up, what should you be looking for? The most common red flags are changes in your bowel habits. If you notice persistent diarrhea, constipation, or a feeling that you haven’t fully emptied your bowels, it’s worth a chat with your GP. Blood in the stool is another big one – even a tiny amount can signal trouble. Some people also feel abdominal pain, unexplained weight loss, or constant fatigue. These symptoms can feel vague, but the key is to treat them as a cue to get checked, not to ignore them.
Don’t fall into the “it’s probably nothing” trap. Most of us have a busy life and may push a doctor’s visit to the back of the list. However, a quick appointment can rule out serious issues or point you toward a colonoscopy. Early detection boosts survival rates from about 50% to over 90% when the cancer is caught at stage I or II.
Screening Saves Lives
The National Health Service offers a free bowel screening program for everyone aged 60‑74, and many regions now include people starting at 50. The test is simple: you receive a kit in the mail, collect a small sample of stool, and send it back. If the lab finds abnormal cells, you’ll be invited for a colonoscopy where doctors can remove polyps before they turn cancerous.
If you’re under the official screening age but have a family history of colorectal cancer, talk to your doctor about getting screened earlier. Having a first‑degree relative with the disease can double your risk, so personalized screening plans are a smart move.
Now, where does exercise fit in? Regular physical activity does more than keep your weight in check – it directly lowers the risk of colorectal cancer. Studies show that folks who jog, cycle, or even brisk‑walk for at least 150 minutes a week cut their odds by up to 25%. Exercise helps your gut move faster, reducing the time harmful substances sit against the lining of your colon.
Here’s a quick plan you can follow without needing a gym membership:
- Walk or bike to work: Turn a daily commute into a mini‑workout.
- Take the stairs: One extra flight every few minutes adds up.
- Mini‑sessions: Three 10‑minute walks during lunch, after dinner, and mid‑morning keep you moving.
- Join a local sports club: Northwich Multi‑Sports Hub offers football, badminton, and fitness classes that make exercise social.
Pairing these habits with a balanced diet rich in fibre, fruits, and vegetables gives your colon the best environment to stay healthy. Aim for at least five portions of fruit or veg a day and cut back on processed meats.
Bottom line: Knowing the signs, getting screened on schedule, and staying active are three low‑effort steps that dramatically lower your colorectal cancer risk. If something feels off, trust your gut (pun intended) and book that appointment. Your future self will thank you.
