Have you ever ignored gum bleeding, thinking it was just a minor issue? Do you suffer from recurrent mouth ulcers but pay no attention to them? Or have you ever felt embarrassed by bad breath but never investigated the root cause?

These signs may seem insignificant, but in reality, they could be warning signals of oral cancer.

Mr. Truong is a typical example. He ignored his gum bleeding for a long time, assuming it was due to internal heat or brushing too hard. However, when the pain became severe and a tumor appeared in his mouth, he finally went for a check-up—only to be diagnosed with oral cancer. This unexpected diagnosis left his family in shock and regret for not paying attention to the early warning signs.

Oral Cancer: A Disease That Cannot Be Ignored

Oral cancer may seem like a distant concern, but in reality, it can develop silently in daily life. The disease does not disappear simply because we ignore it. On the contrary, it can become more severe if not detected and treated promptly.

Therefore, proper oral hygiene and early recognition of warning signs are crucial to preventing oral cancer.

Let’s explore the key warning signs to detect this dangerous disease early!

6 Warning Signs of Oral Cancer

1. Gum Bleeding – Not a Minor Issue!

If your gums bleed frequently for no apparent reason, even without brushing, be cautious! This could be a sign of gingivitis, periodontitis, or even precancerous oral lesions. 💡 Advice: If your gums bleed continuously, visit a dentist immediately!

2. Persistent, Non-Healing Mouth Ulcers

Normal mouth ulcers heal within 7–10 days. However, if an ulcer persists, does not heal, or keeps recurring, you should be on alert! 💡 Advice: If a mouth ulcer lasts more than two weeks, get checked to rule out cancer risks.

3. Persistent Bad Breath

Does bad breath persist despite regular brushing and mouth rinsing? It could be due to an infection or the presence of cancerous cells releasing unpleasant odors. 💡 Advice: If bad breath persists, consult a dentist to determine the cause.

4. Dry Mouth and Constant Thirst

Persistent dry mouth that does not improve even with drinking water could indicate a salivary gland disorder—potentially linked to oral cancer. A lack of saliva allows bacteria to thrive, increasing the risk of infections and oral damage. 💡 Advice: If dry mouth persists, check your salivary glands and overall oral health.

5. Loose Teeth Without Any Impact

If your teeth become loose without any known cause, such as trauma or falling, it could indicate that your jawbone is being affected by cancer. Surrounding tissues may be damaged, causing teeth to lose their support. 💡 Advice: If teeth loosen or fall out suddenly, seek a dental examination immediately!

6. Lumps or Growths in the Mouth

If a lump or hard mass appears in the mouth, even if it is painless but does not go away after a few weeks, it could be a serious warning sign. If the lump grows and makes eating or speaking difficult, it requires immediate attention. 💡 Advice: If a lump in your mouth does not shrink after two weeks, visit a hospital for a check-up immediately.

How to Prevent Oral Cancer?

1. Maintain Proper Oral Hygiene

✅ Brush your teeth twice a day with fluoride toothpaste.

✅ Rinse with salt water or antibacterial mouthwash.

💡 Benefit: Reduces bacteria, prevents gum disease, and maintains oral health.

2. Quit Smoking and Limit Alcohol

🚫 Smoking is the leading cause of oral cancer.
🚫 Alcohol increases the risk of mouth tissue damage, facilitating cancer cell growth.

💡 Advice: If you smoke or drink alcohol regularly, reduce or quit to protect your health.

3. Get Regular Dental Check-Ups

🦷 Visit a dentist at least every six months for oral health examinations.
🔍 Early detection of abnormalities increases the chances of successful treatment.
