Oral Cancer -
Rôle of GDP in
Cancer Prevention & Diagnosis
The dentist (GDP) is in a unique position to help in oral
cancer discovery and diagnosis.

GDP, by training and experience, knows what the oral
cavity should look like and be aware when oral tissues look

GDP's involvement includes prevention, early diagnosis and
the care of patient post-treatment for cancer.


  • Actively discourage smoking & betel nut use

  • Encourage moderation of alcohol intake

  • Health promotion & education on Oral Cancer

  • Provide check-ups for œdentulous ± institutionalised
    elderly & otherwise high-risk non-attenders

Case law has already established that a dentist’s duty of
care includes an obligation to examine the whole mouth.

A typical legal complaint might allege failure to recognise
the possibility of a
malignancy having noted swollen gums
and loose teeth, for example, with a lack of evidence of
adequate medical and social history-taking and delay in
making a specialist referral.

Dentists need to be sure that they can, if necessary,
answer questions like these:

  • Did you know that a particular patient fell into an oral
    cancer high risk group and what did you do in the
    light of that knowledge?

  • Were the medical, social and dental histories taken

  • Did you investigate the health of soft tissues
    thoroughly enough?

  • Was a decision not to refer the appropriate one in the

Early Diagnosis:

  • Be vigilant & suspicious

  • Always examine mucosa as well as teeth

  • Refer all high-risk lesions on discovery

  • Monitor low-risk pre-malignant lesions

  • Perform biopsy appropriately

This presupposes that the
GDP is comfortable recognising pre-malignant lesions
and is
au fait with them.  Shrugging your shoulders or referring any oral pathology
to the
OMFS Department are not necessarily the most efficacious or responsible

Continuous Professional Development, there is the expectation that GDP’s
should be more aware and be able to recognise oral lesions.

Also, though not happening yet in this country, failure to recognise such lesions and
act accordingly may be regarded as malpractice or even negligence.

The parallels have already been drawn by the defence unions between the lack of
diagnosis and treatment of periodontal disease and oral cancer.

I don’t believe many
GDP’s will biopsy the lesion; no real financial incentives and
also the worry that biopsying the lesion may ‘muddy the pitch’ for further
investigations and treatment.
After Treatment:

  • Manage simple denture problems after surgery

  • Monitor for recurrence, new pre-malignant lesions & second primary tumours

  • Monitor for cervical (neck) metastases

  • Maintain morale of & provide additional support to patients & their relatives

Theoretically, the
GDP should know how to manage a dry mouth and its sequelae
cervical caries, periodontal disease & candidal infections).  The GDP should
have either literature or even the products used in the amelioration of

If the
GDP can do a competent oral screening, than monitoring for a recurrence or
a new cancer or a pre-malignancy is no different than the oral screening.
