Colorectal Cancer, CARE2CURE

Overview

What is colorectal cancer?

Colorectal cancer (cancer of the colon or rectum) is rising rapidly in India, particularly in urban populations. The shift toward processed food, low-fibre diets, sedentary lifestyles, and increased red meat consumption has pushed it into the top five cancers in Indian cities. The good news: it's slow-growing and highly preventable with screening, since most cases begin as benign polyps that can be removed before they turn cancerous.

⚠ Risk Factors

Age 50 and above (most cases)
Family history of colorectal cancer or polyps
Personal history of inflammatory bowel disease (IBD), Crohn's, ulcerative colitis
Inherited genetic syndromes (Lynch syndrome, FAP)
Diet high in red and processed meats, low in fibre
Obesity and sedentary lifestyle
Smoking and heavy alcohol use
Type 2 diabetes

🔍 Symptoms to Watch

A persistent change in bowel habits (diarrhoea, constipation, narrow stools)
Rectal bleeding or blood in stool
Persistent abdominal discomfort, cramps, or gas
Feeling that the bowel doesn't empty completely
Unexplained weight loss
Weakness or fatigue (often from anemia caused by slow blood loss)
Iron-deficiency anemia in older adults, needs investigation

🩺 Screening & Detection

Stool test (FOBT or FIT): Every 1–2 years from age 45–50.
Colonoscopy: Every 10 years starting at 45–50 (or earlier with family history).
Sigmoidoscopy: Every 5 years as an alternative to colonoscopy.
CT colonography: Every 5 years; less invasive alternative.
If you have a first-degree relative with colorectal cancer, start screening 10 years before their age at diagnosis.

🛡 Prevention

Eat a high-fibre diet, whole grains, legumes, vegetables, fruits
Limit red and processed meat
Exercise at least 30 minutes a day
Maintain a healthy weight
Limit alcohol; don't smoke
Get screened from age 45–50, earlier with family history
Treat any polyps found during screening, this prevents most cases

When should you see a doctor?

Any rectal bleeding, persistent change in bowel habits, or unexplained anemia in adults over 40 needs medical evaluation. Don't be embarrassed to discuss bowel symptoms with your doctor, this is one of the most preventable cancers, but only if caught early.
