Colorectal Cancer: Screening Saves Lives

Colorectal Cancer : Screening Saves Lives

Colorectal cancer—cancer that starts in the colon or rectum—is one of the most common and preventable cancers worldwide. The good news? When detected early through screening, colorectal cancer is highly treatable and often curable. Despite this, many people delay or skip screening altogether.

Dr. Prashanth, a leading GI and Cancer Surgeon in Hyderabad, emphasizes that early screening can literally save lives. In this blog, you’ll learn why screening matters, who should get checked, and what options are available.

Why Screening for Colorectal Cancer Matters

Colorectal cancer often begins as small, noncancerous growths called polyps on the inner lining of the colon or rectum. These polyps can silently grow for years and may eventually turn into cancer if not removed.
The problem? In its early stages, colorectal cancer usually has no symptoms. By the time signs appear, the cancer may have spread—making it harder to treat.
Regular screening allows:
- Early detection of cancer when treatment is most effecti
- Prevention, by removing pre-cancerous polyps
- Better outcomes and survival rates

Who Should Get Screened—and When

Screening isn’t just for people with symptoms or family history. It’s recommended for most adults, starting at age 45, even if you’re feeling perfectly healthy.

Here’s a general guideline:

Average Risk Individuals

Start screening at age 45
Continue until age 75
After 75, discuss risks and benefits with your doctor

Higher Risk Individuals

You may need earlier and more frequent screening if you:

Have a family history of colorectal cancer or polyps
Have inflammatory bowel disease (IBD) like ulcerative colitis or Crohn’s disease
Have a history of colorectal polyps or certain genetic syndromes
Experience unexplained symptoms such as blood in stool, changes in bowel habits, or persistent abdominal pain

In such cases, screening may begin as early as age 40 or even earlier, depending on your risk profile.

Common Symptoms of Colorectal Cancer (Don’t Wait for These)

While early stages often have no symptoms, watch for these warning signs:

Blood in the stool (bright red or dark)
A change in bowel habits (constipation or diarrhea)
Persistent abdominal discomfort or bloating
A feeling of incomplete bowel movement
Unexplained weight loss
Fatigue or weakness
Iron-deficiency anemia

If you experience any of these, consult Dr. Prashanth right away.

Types of Colorectal Cancer Screening Tests

There are several effective ways to screen for colorectal cancer. Dr. Prashanth recommends the most appropriate option based on your risk factors, age, and preferences.

1. Colonoscopy

Considered the gold standard for screening
Allows direct visualization and removal of polyps during the same procedure
Done every 10 years (or more often if polyps are found)

2. Stool-Based Tests

FIT (Fecal Immunochemical Test): Checks for hidden blood in stool; done yearly
Stool DNA test (e.g. Cologuard): Detects abnormal DNA and blood; done every 3 years

These tests are non-invasive but must be followed by a colonoscopy if results are positive.

3. Flexible Sigmoidoscopy

Examines only the lower part of the colon
Usually done every 5 years with FIT every 3 years

What to Expect During a Colonoscopy

At Dr. Prashanth’s center in Hyderabad, colonoscopies are performed in a safe, comfortable environment using sedation. The procedure takes about 30 minutes, and patients usually go home the same day.

Preparation: A special liquid is taken the day before to clear the bowels
During the procedure: A thin tube with a camera is inserted through the rectum to examine the colon
If polyps are found: They can be removed immediately and sent for biopsy
