Oral cancer—including cancers of the lips, tongue, gums, floor/roof of the mouth, and throat—is often painless in its early stages, which is why it can go unnoticed until it’s more advanced. But when caught early, the 5-year survival rate exceeds 80%.
The key? Knowing what to look for—and acting quickly.
Here are 7 early warning signs that warrant a visit to your dentist or doctor:
🔍 1. A Sore That Doesn’t Heal in 2–3 Weeks
- What it looks like: A red or white patch, ulcer, or blister inside the mouth that bleeds easily and refuses to heal.
- Why it matters: Normal mouth sores (like canker sores) heal within 10–14 days. Persistent sores may be precancerous or cancerous.
- ✅ Action: See a healthcare provider if it lasts longer than 2 weeks.
🩸 2. Unexplained Bleeding or Numbness
- What it feels like: Spontaneous bleeding from the gums, tongue, or cheeks—or numbness/tingling in the lips, tongue, or jaw.
- Why it matters: Tumors can irritate tissue or press on nerves.
- ✅ Action: Don’t assume it’s “just gingivitis.” Get it checked.
