This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. Ontario is used as an explicit Canadian implementation example, not as a national rule. Verify the equivalent pathway, formulary and escalation route in the patient鈥檚 province or territory.

Ontario source: bounded use

Ovarian cancer pathway map supplies a Canadian implementation example for this summary. It must not be presented as the rule outside Ontario.

Source-attributed clinical priorities

  • Assess persistent bloating, early satiety, pelvic or abdominal pain, urinary change, mass and family cancer history.
  • Use pelvic imaging and biomarkers within the provincial pathway, recognizing that a marker alone cannot diagnose or exclude cancer.
  • Refer a suspicious adnexal mass to gynecologic oncology before definitive surgery when feasible.
  • A normal tumor marker does not exclude ovarian cancer in a patient with a concerning mass or persistent symptoms.

Practical assessment and management workflow

1
Record symptom frequency and persistence, menopausal status, family history and prior breast or ovarian cancer.
2
Examine abdomen and pelvis with consent and arrange pelvic ultrasound and indicated biomarkers.
3
Use a Canadian risk assessment and refer a suspicious adnexal mass to gynecologic oncology.
4
Coordinate genetic assessment and ensure diagnostic results and operative planning reach the specialist team.

Safety, red flags and urgent escalation

  • Acute pain with a mass may represent torsion or rupture and needs emergency assessment.
  • Ascites, bowel obstruction or major respiratory compromise requires urgent care.
  • Avoid definitive surgery outside a gynecologic-oncology plan when malignancy is strongly suspected and transfer is feasible.
