Cancer often begins with subtle symptoms that may seem harmless. “Recognizing the warning signs and seeking medical attention promptly can make all the difference in early detection and successful treatment.” Persistent, unexplained pain is one of the most alarming signals.

Back Pain
While common from strain or posture, “when back pain is persistent and unexplained, it could be a clue of something more serious.” Early cancers of the lungs, pancreas, or kidneys may press on nerves or bones, causing lasting pain. Pancreatic cancer often starts this way. If rest or painkillers don’t help, see a doctor.

Abdominal Pain
“Early-stage stomach cancer… can lead to discomfort in the upper abdomen,” while ovarian cancer may bring pelvic pain, bloating, or appetite changes. Pain that is frequent, recurring, or paired with weight loss, nausea, or eating problems needs medical attention.

Headaches
“Frequent or severe headaches, especially those that are unusual for you, could signal a problem in the brain.” Brain tumors may also cause dizziness, blurred vision, or cognitive changes. Pain often worsens in the morning or after lying down.

Conclusion
“Pain should never be ignored, especially when it is persistent or unexplained.” Early detection greatly improves treatment and survival.
