Endometriosis and HPV (human papillomavirus) are two key women’s health concerns that can benefit from early identification, lifestyle adjustments and interventions. Primary care visits present key opportunities to engage young women on help-seeking behaviours to optimise their health.

Preventative care and education about women’s health, given as early as the adolescent years, can have far-reaching benefits across a woman’s life course trajectory – such as optimising preconception health, reducing disease likelihood or delaying onset.

Obstetrics and gynaecology experts from KK Women’s and Children’s Hospital (KKH) share recommendations for patient engagement in the primary care setting:

"At KKH, about 90 per cent of women with severe HPV-related diseases, such as cervical cancer, are aged 30 and older.

We encourage HPV vaccination in early adolescence to confer protection against HPV infection in men and women from an earlier age, and reduce the risk of HPV-related diseases."

Dr Wang Junjie, Head and Senior Consultant, Department of Gynaecology Oncology, KKH

​HPV : Advice for GPs
​What is HPV?
  • ​The human papillomavirus (HPV) is a virus that can cause infections in different parts of the body in men and women, such as genital warts. Some HPV strains may also infect the skin of the fingers, hands, mouth, throat and face.

  • While most infections are transient and resolve on their own within two years, some high-risk HPV strains can lead to severe diseases such as cervical cancer in women, and cancer of the throat, penis and anus in men.

  • Most people with HPV may never develop symptoms or health problems, and do not know that they are infected.

  • There is currently no cure or treatment for HPV.
​What is the disease burden?
  • ​About 85 per cent of sexually-active individuals who do not get the HPV vaccine have HPV infection at some point in their lives.

  • At the Colposcopy-dysplasia Clinic at KKH:
    • There are about 2,170 new cases a year, most of which are HPV-related.
    • About 90 per cent of women with severe HPV-related diseases, such as cervical cancer, are aged 30 and older.
​How can it negatively impact preconception health?
​HPV is the leading cause of cervical cancer
  • More than 70 per cent of cervical cancer are caused by HPV types 16 and 18 – the two common high-risk HPV strains.
  • Cervical cancer is the 10th most common cancer in women in Singapore.

Risk of transmission between partners, mother-to-child
  • HPV spreads from person to person through anal, vaginal, oral sex or via close skin-to-skin touching during sexual activity.
  • There is also a low risk of transmission from a pregnant woman to her baby, such as during childbirth.
​How can early education help?
​Early education and advocacy of HPV awareness can help to:
  • Encourage HPV vaccination in early adolescence to confer protection against HPV infection from an earlier age
  • Reduce the risk of HPV-related diseases such as cervical cancer
  • Reduce overall HPV circulation in the community
​What can the GP do?
  • ​Encourage HPV vaccination from early adolescence. In Singapore, HPV vaccination is recommended between nine and 26 years of age, and most effective before exposure through sexual activity. Individuals beyond this age range can still benefit from vaccine-generated protection against infections from strains they were not previously exposed to.

  • Dispel misconceptions that HPV vaccination is harmful or encourages early sexual activity. The safety data for all HPV vaccines indicate no severe adverse effects or reactions linked to vaccination. No research links the taking of HPV vaccine with increase in sexual activities.

  • Recommend women to continue with regular, age-appropriate cervical screening* as no vaccine prevents all types of HPV that can cause cervical cancer.
*Pap smear once every three years for women aged 25-29 years; HPV DNA test once every five years for 30 years and above.

"Majority of women who present to KKH with endometriosis-related symptoms and problems are aged 20 to 40 years old. Diagnosis from the onset of symptoms can be delayed by up to 10 years.

Proactively engaging women on their menstrual health during primary care visits can bring about early detection and intervention to reduce the burden of endometriosis across their lifespan, control disease progression and protect their fertility."

​Endometriosis: Advice for GPs
​What is endometriosis?
  • In women with endometriosis, cells normally found in the inner uterine lining grow in areas such as the ovaries, fallopian tubes, pelvis or lower abdominal cavity.

  • Severe endometriosis can manifest as adhesions, ovarian cysts and deep infiltrating endometriosis involving areas such as the urinary bladder, ureters and bowel.

  • General symptoms can include painful periods; heavy or irregular periods; chronic pelvic pain, fatigue; painful sexual intercourse; pelvic mass from large ovarian cysts; enlarged womb from associated adenomyosis; painful bowel- or urinary-related symptoms during periods and difficulty in getting pregnant.
​What is the disease burden?
  • Endometriosis is a progressive disease that affects about one in 10 women in their childbearing years.

  • Majority of women who present to the KKH Minimally Invasive Surgery Unit with such symptoms and problems are aged 20 to 40 years old. Some women only realise they may have endometriosis whilst undergoing fertility treatment.

  • KKH treats about 1,200 women with endometriosis-related problems every year.
​How can it negatively impact preconception health?
​Subfertility and challenges with conceiving
  • About 30 to 50 per cent of women with endometriosis encounter challenges conceiving.
  • Endometriosis can negatively impact a woman’s fertility in the following ways:
    • Localised inflammation
    • Scarring in the pelvis and adhesions (where pelvic tissues and organs stick to each other)
    • Ovarian endometriotic cysts
    • Damaged fallopian tubes
    • Impaired embryo implantation
    • Poorer egg quality
    • Decreased egg supply or ovarian reserve

Delays in diagnosis and increased disease burden
  • Diagnosis of endometriosis can be delayed by up to seven to 10 years from the onset of symptoms. The non-specific nature of symptoms reduces patients’ awareness of the need for a doctor’s visit, resulting in missed opportunities for diagnosis.
  • This long interval from onset to diagnosis can lead to disease progression, prolonged pain, loss of fertility, psychological stress, strain on personal relationships, loss of workplace productivity and poor quality of life.
​How can early detection help?
​Early detection, treatment and prevention of complications can help to:
  • Provide pain relief
  • Control and suppress disease progression
  • Preserve and protect fertility
  • Optimising the woman’s quality of life across her lifespan
​What can the GP do?
  • Proactively engage female patients on their menstrual health.

  • Keep a look out for any unusual signs or symptoms that may suggest endometriosis.

  • Dispel misconceptions and stigma that it is normal to suffer from period pain. Encourage patients to discuss menstrual concerns openly.

  • Encourage women to seek gynaecological care when menstrual pain affects their day-to-day activities and quality of life.

  • Refer women to seek urgent medical attention if experiencing acute abdominal pain or rapidly worsening menstrual symptoms.
