Cancer Warning Signs

ET Online

Persistent Cough

A cough lasting more than a few weeks—especially one that keeps getting worse—could be a sign of lung cancer. If it's dry, comes in spasms, or leads to coughing up blood, it needs immediate medical attention.

Unexplained Changes in Bowel Habits

Frequent trips to the toilet, looser stools, or spotting blood in your stool may be linked to bowel cancer. These changes can happen without any other signs and often go unnoticed.

New Lump or Swelling in the Body

A sudden, painless lump—especially one that slowly grows—can sometimes mean cancer. Such lumps can appear in the breast, neck, testicles, or even limbs and should always be checked.

Moles That Change Shape, Size or Colour

Skin changes, especially in moles, can be an early sign of melanoma. If a mole becomes irregular, darker, or starts bleeding, it’s best to get it looked at right away.

Unexpected Weight Loss

Losing a lot of weight without trying could be an early sign of cancers such as those in the stomach, lungs, pancreas, or esophagus. It’s one of the first visible signs in many cancer cases.

Ongoing Pain Without a Clear Cause

Chronic pain that lasts for weeks or even months, and doesn't seem related to an injury, could be your body’s way of signaling trouble. It may feel sharp, dull, or like a burning sensation.

Trouble Swallowing Food

Difficulty swallowing—also called dysphagia—can be caused by a tumor in the throat or esophagus. If it feels like food gets stuck or swallowing becomes painful, it’s time to consult a doctor.
