Final answer:
The markers for ovarian cancer are CA-125, HE4, and CEA, with CA-125 being a significant protein biomarker for this cancer. These markers aid in the diagnosis and monitoring of ovarian cancer and can indicate the presence or progression of the disease.
Step-by-step explanation:
The markers associated with Ovarian Cancer are CA-125, HE4, and CEA. These markers are considered cancer-specific and tissue-specific markers that may indicate the presence of ovarian cancer. CA-125 is a well-known protein biomarker for this type of cancer, whereas HE4 (Human epididymis protein 4) is also used in conjunction with CA-125 to improve the specificity of ovarian cancer testing. CEA, or carcinoembryonic antigen, is another marker that can be elevated in a variety of cancers, including ovarian cancer, although it is not as specific as CA-125 or HE4.
Tissue-specific markers, like CA-125, can be elevated in specific types of cancer, leading healthcare providers to investigate certain tissues more closely. However, not all elevated marker levels are indicative of cancer, and they can be present in other conditions as well. These markers are used not only for diagnosis but also for monitoring treatment response and disease progression.
