The whole process can be divided into two steps.
Ruling out ovarian cancer
The presence of ovarian cancer can be clarified by taking a history gynaecological examination, tumour marker tests and imaging. If there is no abnormality in the double and triple examination, ultrasound can be done to determine the condition of the ovaries bilaterally, to determine whether there is a tumour in the ovary and to clarify the local tumour size and blood flow. Secondly, tumour marker tests can also help to rule out ovarian cancer. The specific tumour marker for ovarian cancer is CA125 and if the CA125 index is high, it needs to be taken seriously. If the presence of ovarian tumour is suggested by ultrasound, CT, MRI or PET-CT, laparoscopic exploration and full staging surgery to obtain pathology for examination should be done promptly in this case. Genetic testing of the tumour tissue can identify the presence of genetic mutations in the system.
Ruling out whether the tumour is hereditary
Blood is drawn for genetic testing to clarify the presence of deleterious mutations in genes predisposing to hereditary ovarian cancer.
