What is Colorectal Cancer?

Colorectal cancer starts in the colon or rectum. Most cases begin as polyps — small growths that can turn cancerous over 10–15 years. It is the 3rd most common cancer worldwide and the 2nd deadliest, but it is highly preventable and curable when caught early.

2025 Key Statistics (US)

  • New cases: ~153,000
  • Deaths: ~53,000
  • Early-stage (I) 5-year survival: >90%
  • Metastatic (IV) 5-year survival: ~15%
  • Rising 1–2% per year in adults under 50

Risk Factors

Non-modifiable: Age >45 • Family history • Lynch syndrome / FAP • IBD • Type 2 diabetes
Modifiable: Obesity • Smoking • Heavy alcohol • Red/processed meat • Low fiber • Sedentary lifestyle

Early Warning Signs (Often Silent!)

Blood in stool • Persistent bowel changes • Abdominal pain • Unexplained weight loss • Fatigue • Anemia

Never assume rectal bleeding is “just hemorrhoids” — get it checked immediately.

  • Targeted therapy (anti-EGFR, anti-VEGF)
  • Immunotherapy (pembrolizumab/nivolumab for MSI-H tumors)
  • Liver-directed therapies for metastases
  • Clinical trials (CAR-T, vaccines)

Prevention (Up to 60% of Cases Avoidable)

  • Screen at 45
  • High-fiber, plant-heavy diet
  • Exercise 150+ min/week
  • Limit red/processed meat
  • No smoking, moderate alcohol
  • Maintain healthy weight

FAQ

Q: When should I start screening?
A: Age 45 for average risk; earlier with family history.

Q: Can young people get it?
A: Yes — rates are rising fastest under age 50.

Q: Is it hereditary?
A: Only 5–10% are strongly hereditary (Lynch/FAP), but family history matters.

Bottom line: Screening starting at 45 + healthy lifestyle = the best protection.

Breast Cancer:Complete Guide to Prevention, Symptoms, Diagnosis & Treatment Options

What is Breast Cancer? Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast. It is the most common cancer among women worldwide, but it can also affect men. The breast consists of glands called lobules that produce milk and thin tubes called ducts that carry milk to the nipple. Cancer typically begins in the cells lining these ducts or lobules. Understanding breast anatomy helps in identifying where breast cancer typically develops. Breast cancer can spread when cancer cells invade nearby healthy tissue or travel through the bloodstream or lymphatic system to other parts of the body in a process called metastasis.
