9 Possible Signs of Oral Cancer
Oral cancer can develop on the tongue, lips, gums, floor of the mouth, cheeks, palate, or other oral tissues. Many of these symptoms can be caused by harmless conditions, but persistent changes—especially those lasting more than 2–3 weeks—should be assessed by a dentist or doctor.
⠀
🟣 1. Non-Healing Mouth Ulcer
➟ A mouth ulcer that does not heal within 2–3 weeks needs assessment
➟ It may be painless at first
➟ Persistent ulcers can also result from trauma, infection, or inflammatory conditions, so examination is important
⠀
🟣 2. Persistent White Patch
➟ A white patch that does not wipe away may be called leukoplakia
➟ Many white patches are benign, but some can contain precancerous or cancerous changes
➟ Any persistent unexplained white patch should be checked
⠀
🟣 3. Red or Red-White Patch
➟ Persistent red patches are called erythroplakia, while mixed red-white patches may be termed erythroleukoplakia
➟ These can have a higher risk of abnormal cell changes than many white patches
➟ Persistent lesions need prompt professional assessment
⠀
🟣 4. Mouth or Neck Lump
➟ A persistent lump, thickening, or swelling in the mouth or neck can be a warning sign
➟ Enlarged neck lymph nodes may sometimes occur if cancer spreads
➟ A neck lump lasting more than a few weeks should be medically assessed
⠀
🟣 5. Unexplained Oral Bleeding
➟ Bleeding from a mouth lesion without an obvious injury may require evaluation
➟ Gum disease, trauma, and dental problems are much more common causes
➟ Recurrent unexplained bleeding should not be ignored
⠀
🟣 6. Persistent Mouth Pain
➟ Ongoing pain, soreness, or burning in one area of the mouth can occasionally be associated with oral cancer
➟ Some oral cancers are painless in their early stages
➟ Persistent discomfort despite removing obvious causes should be checked
⠀
🟣 7. Difficulty Chewing or Swallowing
➟ You may feel pain, discomfort, or difficulty when chewing or swallowing
➟ Some people describe a persistent feeling that something is stuck in the throat
➟ Progressive swallowing difficulty deserves prompt medical assessment
⠀
🟣 8. Numbness of the Lip or Tongue
➟ Persistent numbness, tingling, or altered sensation may indicate nerve involvement
➟ Dental procedures and nerve injuries can also cause similar symptoms
➟ Unexplained or progressive numbness should be evaluated
⠀
🟣 9. Unexplained Loose Tooth
➟ A tooth becoming loose without significant gum disease or trauma can occasionally be a warning sign
➟ Persistent swelling, pain, or poor healing after a tooth extraction may also need investigation
➟ Dental assessment is important to determine the cause
⠀
🟣 Important Risk Factors
➟ To***co smoking or chewing to***co
➟ Heavy alcohol use, particularly when combined with to***co
➟ Increasing age
➟ Previous oral cancer or precancerous lesions
➟ Significant sun exposure increases the risk of lip cancer
➟ HPV is an important cause of oropharyngeal cancer, particularly cancers of the tonsil and base of tongue
⠀
🟣 How Oral Cancer Is Diagnosed
➟ A dentist or doctor examines the mouth, tongue, throat, and neck
➟ Suspicious lesions may require referral to an oral medicine, oral surgery, ENT, or head-and-neck specialist
➟ A biopsy is required to confirm whether a lesion is cancerous
➟ Imaging such as CT, MRI, PET/CT, or ultrasound may be used if cancer is diagnosed
⠀
🟣 Treatment
➟ Treatment depends on the site, size, type, and stage of the cancer
➟ Surgery is commonly used for localised oral cancer
➟ Radiotherapy may be used alone or with surgery
➟ Chemotherapy, immunotherapy, or targeted treatments may be used in selected advanced cancers
➟ Early diagnosis generally allows simpler treatment and better outcomes
⠀
🟣 See a Dentist or Doctor If
➟ An ulcer, red patch, or white patch lasts more than 2–3 weeks
➟ You develop an unexplained mouth or neck lump
➟ There is persistent oral bleeding, pain, or numbness
➟ Swallowing or chewing becomes increasingly difficult
➟ A tooth becomes loose without an obvious dental cause
