Correcting common misconceptions with clear, evidence-based information – and clearly identified GEM clinical positions

1. MYTH: Severe period pain is normal

A woman with hair in a messy bun, wearing a lilac sweater and light trousers, sits at a desk beside a closed laptop and papers, her head resting on one hand and her other hand on her stomach; a dog lies on a sofa behind.

FACT: Severe period pain that disrupts school, work, sleep or daily activities deserves assessment. Endometriosis is one possible cause.

2. MYTH: Teenagers cannot have endometriosis

A teenage girl with long curly hair, wearing a lilac sweater, jeans and white trainers, sits in an armchair gesturing as she talks with a woman in navy scrubs and a beige cardigan on a rolling stool; a backpack is on the floor.

FACT: Endometriosis can begin in adolescence. Severe or persistent period-related symptoms deserve assessment.

3. MYTH: Normal imaging rules it out

A woman with curly hair in a loose bun, wearing a lilac sweater and jeans, sits in a cream armchair gesturing as she talks with a woman in navy scrubs holding a clipboard, in front of a scanning machine with a monitor.

FACT: Ultrasound and MRI help identify endometriomas and many deep lesions, but superficial disease may be invisible. Negative imaging does not exclude endometriosis.

4. MYTH: Pain relief means disease is gone

A woman in a lilac cardigan over a white top sits at a table resting her cheek on one hand and touching a small lilac box with the other, beside a blank desk calendar, a floral mug, flowers and a navy notebook.

FACT: Hormonal treatment can reduce symptoms and suppress disease activity. Feeling better does not establish that all lesions have disappeared. Follow-up remains important.

5. MYTH: Stage measures pain severity

A woman with long curly hair in a green cardigan, white top and jeans sits on an examination couch gesturing as she talks with a woman in a white coat over navy scrubs, wearing a stethoscope, who writes on a clipboard.

FACT: Stage is not a pain scale. Limited visible disease may cause severe symptoms, while extensive disease may cause less pain. Treatment should reflect symptoms and priorities.

6. MYTH: Endometriosis always causes infertility

A woman with long wavy hair in a lilac top, jeans and white trainers walks hand in hand with a man in a navy top and trousers along a stone garden path lined with lavender, with a pond, a stone bridge and a gazebo behind.

FACT: Many affected people conceive naturally; others benefit from fertility care. Options include intrauterine insemination (IUI), in vitro fertilization (IVF) or selected surgery.

7. MYTH: Pregnancy cures endometriosis

A pregnant woman in a lilac dress and cream cardigan sits in a sage armchair with her hands on her belly as a woman in a white coat over navy scrubs, with a stethoscope and clipboard, gestures toward her.

FACT: Pregnancy can change symptoms, but is not a cure and should not be prescribed to treat endometriosis.

8. MYTH: Hysterectomy always cures it

Seen over the shoulder of a woman in a white coat holding a pen over a clipboard, a woman with shoulder-length curly hair in a lilac cardigan sits across the desk, her chin on one hand, gesturing with the other.

FACT: Hysterectomy removes the uterus and prevents carrying a pregnancy. It does not automatically remove endometriosis elsewhere or cure every cause of pain.

9. MYTH: Menopause always ends it

A woman with grey wavy hair, wearing a lilac cardigan, patterned scarf and olive trousers, sits in a cream armchair gesturing as she talks with a woman in a white coat over navy scrubs with a stethoscope, who writes on a clipboard.

FACT: Symptoms may improve after menopause, but endometriosis can persist. New or persistent symptoms still need assessment.

10. MYTH: Everyone needs surgery

Seen from above, a person in a lilac sweater and a person in a white coat with a stethoscope sit at a desk, one pointing to a lilac folder beside a green one; a blister pack of tablets, a blank card and tea sit nearby.

FACT: Surgery helps selected patients. Others can be assessed and treated without an operation. The choice depends on symptoms, goals, risks and preferences.

11. MYTH: Laparoscopy only finds disease

In an operating room, a woman in a blue gown, patterned cap, face mask and white gloves holds a long thin scope with a cable while another woman in a gown, cap and mask holds a coiled cable beside a draped table of long instruments.

FACT: When indicated, laparoscopy can diagnose and treat disease within informed consent and safe limits. Complex treatment may be staged. Clinical diagnosis and treatment do not always require surgery.

12. MYTH: Returning pain proves surgery failed

A woman in a lilac sweater and green trousers sits at a wooden table writing a list in a spiral notebook, her other hand on her stomach, beside a phone and a patterned mug; a dog lies on a sofa behind her.

FACT: Residual or recurrent disease is one possibility. Adenomyosis, pelvic-floor, bowel or bladder problems and nerve-related pain may also contribute. Reassessment matters.

13. MYTH: Endometriosis is cancer

A woman with long curly hair in a lilac sweater sits in a green armchair with her hands clasped under her chin as a woman in a white coat over navy scrubs, with a stethoscope and a navy folder, gestures while talking to her.

FACT: Endometriosis is not cancer. Risk of certain ovarian cancers is increased, but absolute risk remains low; most affected patients do not develop ovarian cancer.

Extra routine cancer screening or preventive surgery is not recommended solely because of endometriosis. Suspicious findings, strong family history or inherited risk require individual assessment.

Evidence & review

Endometriosis: Myths and Facts
Version 1.2 · September 2026

Symptoms and diagnosis

Severe disruptive period pain deserves assessment, including in adolescence. Normal ultrasound or MRI does not rule out superficial endometriosis. Clinical diagnosis and treatment can proceed without mandatory laparoscopy. Laparoscopy can be considered when imaging is negative and empirical treatment is unsuccessful or inappropriate, using shared decision-making.

Treatment, fertility and recurrent symptoms

Hormonal symptom relief does not establish that every lesion has disappeared. Pregnancy and hysterectomy are not guaranteed cures. Endometriosis may persist after menopause. Fertility and treatment decisions are individual, and pain returning after surgery can have more than one cause.

GEM surgical-documentation position

When surgery is appropriate, GEM supports safe inspection, mapping, consented treatment, pathology where appropriate and useful operative records. Preserve the complete unedited video when feasible, with consent and privacy safeguards. This is a GEM quality-of-care position, not a universal legal obligation or a requirement that every patient have surgery. Complex treatment may need a planned later operation.

Cancer risk in context

Endometriosis is not cancer. Risk is increased for some ovarian-cancer types, but the absolute risk remains low and most affected patients do not develop ovarian cancer. The original mixed 1.9% and below 2-5% wording is removed because it combined estimates without a clear population or method. Extra routine cancer screening or preventive surgery is not recommended solely because of endometriosis. A suspicious mass, strong family history or inherited risk warrants individualized evaluation.

The 2026 review and its correction

Bogani and colleagues published the cited 2026 review. Its subsequent corrigendum corrects an affiliation and three references; it does not announce revised risk estimates or a retraction. The review abstract and the complete corrigendum were inspected; the full original review was not.

Medical information

Seek urgent or emergency assessment for severe or rapidly worsening symptoms.

Version 1.2 · September 2026. Proposed next review: September 2027, or sooner if relevant guidance changes.
