Cancer in pregnancy

High parity is associated with increased risk of cervical cancer: Systematic review and meta-analysis of case–control studies

“…Squamous metaplasia of the transformation zone also increases during pregnancy to reach a maximum during the third trimester. 66 Some other studies have also explained the association between multiple pregnancies and cervical cancer could be due to high detection of cervical abnormalities among pregnant women, 25,26 probably due to migration of endocervix during pregnancy. 67 There are also assumptions that traumas to the uterine cervix during vaginal delivery might be a possible explanation for the positive association between cervical cancer and parity.…”

“…[11][12][13][14][15][16][17][18][19][20] Previous studies reported a positive association between parity and cervical cancer. 11,17,[21][22][23][24] Excess risk of cervical cancer among women with high parity is believed to be linked with a high rate of cervical abnormalities during pregnancy, 25,26 a high detection rate of HPV among pregnant women, 27,28 and some studies also suggest vaginal parity makes local changes to cervical cells due to traumas during birth. 11 Although several previous epidemiological studies documented parity as a risk factor for cervical cancer; the reported strength of association is variable and inconsistent.…”

Hodgkin’s Disease during Pregnancy: Diagnostic and Therapeutic Management

“…Due to the peak incidence among young people it is not rare to diagnose HD in pregnant women. In these cases the incidence varies between 1:1,000 and 1:6,000 deliveries [1][2][3]. Several studies have shown that pregnancy does not worsen the clinical course of the disease; the survival rate in pregnant patients is the same as in nonpregnant patients [4]; pregnant patients do not show any unusual problem [5][6][7].…”
