Abstract
The most common cancer diseases in pregnancy include gynaecological malignancies, malignant melanoma, haematological malignancies, and thyroid carcinoma. Given the fact that a number of malignant disease symptoms are masked by physiological changes in pregnancy, their diagnosis has specific considerations and limitations.
For diagnosis and staging, modalities that do not use ionizing radiation are preferred; therefore, ultrasound examination and magnetic resonance imaging are at the forefront of diagnosis. The use of tumour markers in pregnancy is limited since a number of them are increased physiologically during pregnancy.
Although relatively rare, these diseases should be kept in mind and a patient in whom this disease is suspected referred to a specialized unit.
