What does a high AFP tumor marker mean?

What does a high AFP tumor marker mean?

High levels of AFP can be a sign of liver cancer or cancer of the ovaries or testicles, as well as noncancerous liver diseases such as cirrhosis and hepatitis. High AFP levels don’t always mean cancer, and normal levels don’t always rule out cancer.

Is AFP elevated in colon cancer?

Background. Alpha-fetoprotein (AFP) is produced by some tumors, such as hepatocellular carcinoma and yolk sac tumors, leading to an increase in serum AFP level. However, AFP in colorectal cancer is extremely rare.

What is a CEA marker?

CEA is a type of tumor marker. Tumor markers are substances made by cancer cells or by normal cells in response to cancer in the body. A high level of CEA can be a sign of certain types of cancers. These include cancers of the colon and rectum, prostate, ovary, lung, thyroid, or liver.

What is a normal CEA level?

The normal range is 0 to 2.5 ng/mL (0 to 2.5 µg/L). In smokers, slightly higher values may be considered normal (0 to 5 ng/mL, or 0 to 5 µg/L).

What happens if CEA is high?

A high level of CEA can be a sign of certain types of cancers. These include cancers of the colon and rectum, prostate, ovary, lung, thyroid, or liver. High CEA levels may also be a sign of some noncancerous conditions, such as cirrhosis, noncancerous breast disease, and emphysema.

What is normal CEA level?

What is an AFP tumor?

Alpha-fetoprotein (AFP) is used as a tumor marker to help detect and diagnose cancers of the liver, testicles, and ovaries.

What is CEA in blood test?

The carcinoembryonic antigen (CEA) test measures the level of CEA in the blood. CEA is a protein normally found in the tissue of a developing baby in the womb. The blood level of this protein disappears or becomes very low after birth. In adults, an abnormal level of CEA may be a sign of cancer.

What does high AFP mean in a tumor marker test?

High levels of AFP can be a sign of liver cancer or cancer of the ovaries or testicles, as well as noncancerous liver diseases such as cirrhosis and hepatitis. High AFP levels don’t always mean cancer, and normal levels don’t always rule out cancer. So an AFP tumor marker test is not usually used by itself to screen for or diagnose cancer.

What is an alpha fetoprotein tumor marker test?

Alpha Fetoprotein (AFP) Tumor Marker Test. What is an AFP (alpha-fetoprotein) tumor marker test? AFP stands for alpha-fetoprotein. It is a protein made in the liver of a developing baby. AFP levels are usually high when a baby is born, but fall to very low levels by the age of 1. Healthy adults should have very low levels of AFP.

What are tumor markers in the body?

Tumor markers are substances made by cancer cells or by normal cells in response to cancer in the body. High levels of AFP can be a sign of liver cancer or cancer of the ovaries or testicles, as well as noncancerous liver diseases such as cirrhosis and hepatitis.

Does serum serum CEA and APF predict early gastric cancer?

Our present study found that the positive rates of serum CEA, CA19–9, APF and CA125 were relatively low for early gastric cancer. Elevation of CA19–9 level was correlated with female gender and presence of LNM. Elevation of CEA level was an independent risk factor for the poor prognosis of early gastric cancer.
