10 Common and Overlooked Signs of Cancer You Should Never Ignore | November 10, 2025

5. Lumps or Swellings That Don’t Go Away

Found a lump in your neck, breast, armpit, or groin? Not all lumps are cancer—but if it’s firm, painless, and persistent, don’t wait. Get it checked.

6. Chronic Pain With No Clear Cause

Ongoing pain in your back, bones, or abdomen that doesn’t go away could be a warning. For instance, persistent back pain may be linked to ovarian or colon cancer.

7. Changes in Bowel or Bladder Habits

Sudden constipation, diarrhea, blood in the stool, or painful urination can be more than digestive troubles. These may point to colon, bladder, or prostate cancer.
