23 July 2025 : Cancer is a dangerous disease, but if detected in its early stages, it can often be treated successfully. People usually ignore minor changes in the body that may seem insignificant but could turn into serious threats later on. According to experts, there are certain symptoms that should not be taken lightly if they persist for a long time.
Especially when these symptoms continue for weeks and do not improve with regular treatment, it’s important to stay alert. Doctors say that the body gives us signals — we just need to understand them. Here are 10 signs that should never be ignored, as they could be early indications of cancer. If you or someone you know experiences these symptoms, consult a doctor without delay.
- Sudden weight loss of more than 4–5 kg without any changes in diet or exercise could indicate cancer of the stomach, lungs, pancreas, or esophagus.
- Persistent fatigue, even after rest, may signal blood-related cancers like leukemia or lymphoma.
- A new lump in the neck, armpit, or waist area that is hard, growing, or painless could be a sign of breast, testicular, or lymph node cancer.
- Changes in moles – if a mole’s shape, color, or border changes, or if it becomes itchy, burns, or bleeds, it could be skin cancer (melanoma).
- Blood in stool, urine, vomit, or cough, or unexplained bruises on the body, can be signs of blood disorders or gastrointestinal diseases.
- Persistent dry cough lasting for several weeks or leading to hoarseness could be a symptom of lung or throat cancer.
- Frequent acidity, heartburn, or difficulty swallowing food may be linked to cancer of the throat, stomach, or esophagus.
- Chronic diarrhea or constipation, burning sensation or blood in urine could be early symptoms of prostate, bladder, or colon cancer.
- Pain in the back, abdomen, or joints that doesn’t go away for days and doesn’t respond to medication may point to bone, testicular, or pancreatic cancer.
- Frequent unexplained fevers, heavy night sweats, or recurrent infections can be warning signs of cancers like leukemia or lymphoma.
These symptoms do not necessarily mean you have cancer, but they can act as SOS alarms from your body. The earlier a disease is detected, the better the chances of successful treatment. According to the World Health Organization, the most common cancers worldwide include breast, lung, colon, and prostate cancer. To prevent these, timely screening, a healthy diet, and avoiding tobacco are extremely important.
