February 4 marked World Cancer Day, a global reminder of the importance of early detection in improving survival rates.
The World Health Organization (WHO) emphasizes that recognizing potential cancer symptoms early can lead to better treatment outcomes, especially for cancers like breast, skin, cervical, colorectal, and oral cancer.
Here are seven key warning signs WHO advises people to watch for:
- Unusual Bleeding or Discharge
Unexpected bleeding, such as blood in urine or stool, abnormal vaginal bleeding, or nipple discharge, could indicate a serious condition, including cancer. While there may be other causes, it’s essential to get checked by a doctor. - A Sore That Won’t Heal
A persistent wound that refuses to heal, becomes painful, or starts bleeding may be a sign of skin cancer. WHO advises seeking medical attention if any sore doesn’t improve over time. - Changes in Bowel or Bladder Habits
Persistent constipation, diarrhea, blood in stool, or noticeable changes in stool shape and size could indicate colorectal cancer. Similarly, blood in urine or urinary difficulties might signal bladder cancer. If these symptoms persist, a medical check-up is crucial. - Lumps in the Breast or Other Parts of the Body
Unusual lumps in the breast, testicles, or other body parts should never be ignored. Not all lumps are cancerous, but regular self-examinations and early detection improve treatment success. - A Persistent Cough
A lingering cough, especially if it produces blood or leads to voice changes, could be a symptom of lung or throat cancer. WHO advises seeing a doctor if a cough persists for weeks. - Changes in Moles
Skin cancer is among the most common cancers, and WHO recommends checking moles using the ABCD rule:- Asymmetry: One half of the mole is different from the other.
- Border: Edges are irregular or blurred.
- Colour: The mole has multiple shades instead of one uniform colour.
- Diameter: It’s larger than 6mm (about the size of a pencil eraser).
Any mole that changes in size, shape, or colour should be examined by a healthcare professional.
- Difficulty Swallowing
Persistent difficulty swallowing, a sensation of pressure in the throat or chest, or feeling full too quickly may indicate oesophagal or throat cancer. If these symptoms persist, medical evaluation is necessary.
WHO stresses that recognizing these signs early can make a significant difference in treatment success.
If you notice any of these symptoms, consulting a healthcare professional promptly is the best course of action.
