Seven Cancer Warning Signs Sri Lankans Often Ignore
Every week in my clinic I see the same heartbreaking pattern: a patient who noticed something months — sometimes years — ago, but waited. They waited because they were busy. Because they were afraid of what the answer might be. Because a family member said "it's nothing." Because they tried a home remedy first. By the time they arrived, what could have been a Stage I cancer was now Stage III or IV.
Early detection is not a cliché. It is the difference between a cure and a very difficult fight. The following seven signs are your body's way of asking for attention. Please listen.
1. A Lump You Can Feel
Any new, unexplained lump — in the breast, armpit, neck, groin, or anywhere else — deserves evaluation. In Sri Lanka, many women discover a breast lump and wait, hoping it will go away. Most breast lumps are benign (harmless cysts or fibroadenomas). But the only way to know is to have it checked. Do not wait more than two to three weeks before seeing a doctor.
2. Changes in a Mole or Skin Mark
A mole that changes in colour, size, or shape — or that bleeds without injury — can be an early sign of skin cancer. Use the ABCDE rule: Asymmetry, Border irregularity, Colour variation, Diameter larger than 6 mm, Evolving (changing). Any mole that ticks even one of these boxes needs a dermatologist's eye.
3. A Persistent Cough or Hoarseness
A cough that lasts more than three weeks, especially if it produces blood, or a hoarse voice that does not resolve — these are not just "seasonal" symptoms. They can indicate cancers of the lung, larynx, or throat. In Sri Lanka, where tobacco use and betel chewing are common, these symptoms should be investigated promptly.
4. Blood Where It Should Not Be
This includes:
- Blood in the urine (even once, even painless)
- Blood in the stool, or black tarry stools
- Coughing or vomiting blood
- Unusual vaginal bleeding (between periods, after menopause, after intercourse)
None of these are normal. All of them need investigation.
5. Unexplained Weight Loss
Losing more than 5 kg in six months without trying — without dieting, without increased exercise — is a red flag. The body loses weight when cancer is consuming energy or releasing substances that suppress appetite. This is one of the most commonly overlooked signs because Sri Lankans often consider weight loss "a good thing."
6. Difficulty Swallowing or Persistent Indigestion
Occasional heartburn after a heavy meal is normal. But persistent difficulty swallowing, a feeling that food is getting stuck, or indigestion that does not respond to antacids over several weeks — these can be signs of cancers of the oesophagus, stomach, or throat. Oesophageal cancer is rising in Sri Lanka, partly linked to hot beverage consumption.
7. A Mouth Sore That Does Not Heal
This is the most Sri Lanka-specific warning sign I can give you. Oral cancer is one of the most common cancers in our country, driven largely by betel quid chewing. A white or red patch in the mouth, a sore that does not heal within three weeks, or numbness in the mouth or tongue — go to a dentist or doctor immediately. Oral cancer, caught at Stage I, has an excellent cure rate. Caught at Stage III or IV, it is devastating.
What To Do If You Notice Any of These
Do not search your symptoms on Google at midnight. Do not ask a neighbour. Make an appointment with a doctor — a general practitioner is a fine first step. They will take a history, examine you, and refer you if needed. The National Cancer Hospital (Apeksha, Maharagama) and all district hospitals in Sri Lanka have oncology referral pathways.
The symptom most likely has an innocent explanation. But the one time in many that it does not — catching it early will change everything.
