Question 110 (part 2) · LEK · Ovarian cancer
Tumour markers are substances whose concentration assessment might be used to evaluate the treatment of cancers. Which of the following is false:

- B. a high CA-125 level rules out ovarian cancer.
- C. inhibin concentration measurement might be useful in granulosa cell tumour treatment monitoring.
- D. HE-4 concentration measurement is not used to differentiate uterine sarcomas from myomas .
- E. granulosa cell tumours might produce oestrogens.
Hint
Think about how often CA-125 is normal in early-stage or non-serous ovarian cancer and whether any single value can exclude the disease.
