Symptoms, risk, screening and diagnostic confirmation

Detect Ovarian Cancer is about choosing the right test for the right risk.

An ovarian cancer detection guide covering bloating, pelvic symptoms, CA-125, transvaginal ultrasound, BRCA/Lynch risk, CT and tissue confirmation.

Educational, not personal medical advice. Persistent bloating, early satiety, pelvic/abdominal pain, urinary frequency, weight loss or ascites deserves assessment, especially if new and frequent.
No

average-risk screening has not reduced mortality convincingly.

CA-125

useful in context, weak alone.

TVUS

helps characterize adnexal masses.

Genes

BRCA/Lynch risk changes prevention.

Brief outline

What ovarian cancer means.

Ovarian, fallopian tube and primary peritoneal cancers are often grouped because high-grade serous cancers may start in the tube.

Ovarian cancer care visual
Ovarian cancer is often detected after symptoms or imaging.

Detection frame

Screening is for people without symptoms. Diagnosis is for symptoms, abnormal examination, family history, imaging findings or abnormal labs. The same test can be sensible in one setting and misleading in another.

Do not ignore

Symptoms and signs not to ignore.

BloatingNew, frequent and persistent is important.
Early satietyFeeling full quickly can be a clue.
Pelvic painPersistent symptoms need evaluation.
Urinary frequencyCan be pressure from a mass/ascites.
Weight loss or ascitesConcerning for advanced disease.
Postmenopausal massNeeds structured assessment.

Risk and genetics

Demographics, risks and genetics.

AgeRisk rises after menopause.
BRCA1/2Strongly raises ovarian/tubal cancer risk.
Lynch syndromeRaises endometrial and ovarian risk.
EndometriosisLinked to some subtypes.
Family historyBreast/ovarian clusters matter.
Protective factorsPregnancy, OCP use and tube removal can reduce risk.

Screening

Who should actually be screened?

Average-risk screening with CA-125 and ultrasound is not recommended in many guidelines because false positives and surgeries can outweigh benefit. High-risk genetics is different.

Triage

Pelvic exam

Can find masses but misses many cancers.

Blood

CA-125

Can rise in ovarian cancer and many benign conditions.

Imaging

Transvaginal ultrasound

Characterizes ovarian/adnexal masses.

Staging

CT abdomen/pelvis/chest

Assesses spread when cancer suspected.

Genetics

BRCA/Lynch testing

Can alter prevention and family testing.

Caution

Screening panels

More detection is not automatically fewer deaths.

Images, labs and tissue

Useful tests and what they can miss.

Detection usually needs a chain: suspicion, imaging or lab triage, tissue or cytology when needed, then pathology and molecular testing where it changes management.

Abdominal MRI example
Cross-sectional imaging can help characterize pelvic disease.
PET-CT example
PET-CT can help assess selected advanced disease.

Pros, cons and controversy

Benefits, harms and the false-positive problem.

This is one of the hardest screening problems: symptoms are vague, blood tests are imperfect, and ultrasound can lead to surgery for benign cysts.

Sources and trials

Good starting points.
