Expat health insurance policyholders who are trying to conceive should be aware that the incidence of breast cancer increases with age.
This is the warning from Martin Widschwendter, a professor in women's cancer at UCL and a consultant gynaecological oncologist at the University College London Hospital.
He noted that women who get pregnant later in life generally have a higher chance of developing the disease.
Expatriate medical insurance customers and other people who are diagnosed with cancer during pregnancy can receive the same treatment as other patients who are not carrying children, however.
"Referral to a multidisciplinary team, including breast surgeons, medical and clinical oncologists, obstetricians and neonatologists is strongly recommended," the healthcare professional advised.
"Breast cancer surgery can be safely performed throughout all stages of pregnancy."
His comments come after the American Association for Cancer Research's report recommended that healthcare staff should not delay treatment of breast cancer just because the patient is pregnant.
