Fertility and gynaecological malignancies have an important relationship. A clear inverse relationship exists between family size and the incidence of ovarian and endometrial cancer. Current methods of fertility control have an influence on subsequent development of various gynaecological malignancies. A slightly increased risk of breast cancer has been reported in current users and those who had used hormonal contraceptives (OC s ) within 10 years; this risk declined with time and disappeared after 10 years. Women who started OC before age 20 had a higher relative risk; the disease did not spread beyond the breast in the majority. Most studies found OC to reduce the risk of ovarian and endometrial cancer. The relative risks of squamous cell carcinoma and adenomatous carcinoma of the cervix have been reported to be 1.3 and 1.5, respectively in ever‐users of OC s ; however, the aetiology of cervical cancer is multifactoral. Several reports suggest the beneficial effect of tubal ligation and breast feeding in reducing the risk of ovarian cancer. Therapy of gynaecological malignancies may have an influence on subsequent fertility. Amenorrhoea developing after treatment of hydatidiform mole may be due to choriocarcinoma, recurrent mole or a normal pregnancy. Choriocarcinoma can also develop after a partial mole. The risk of fetal teratogenicity from chemotherapy is present only if conception occurs during or immediately following the treatment cycles. Fertility is not impaired following chemotherapy. Successful pregnancies have occurred in women who have had widespread GTD including cerebral metastases. In the young patient with gynaecological malignancy preservation of fertility is possible. Fertility‐sparing surgery may be safe in early ovarian epithelial cancers and even in advanced germ cell tumours. Recently, the fertility‐sparing surgery of radical trachelectomy and pelvic lymphadenectomy has been carried out for early invasive cervical cancer in young women. Gynaecological cancer occurring in pregnancy is uncommon; it presents the clinician with a difficult situation to manage. In most instances the cancer is treated as though the patient is not pregnant; the timing and mode of delivery needs individualization. The overall prognosis for breast cancer complicating pregnancy is poor. Survival in cervical cancers diagnosed antepartum is similar to the non‐pregnant patient. Ovarian cancer in pregnancy has a good prognosis because of the early stage at diagnosis.
