  • stomach;
  • pancreas;
  • of the colon or rectum;
  • gall.

The Norm Of Alpha-Fetoprotein

The basis of primary diagnosis of liver cancer AFP. In adults the norm that exceed 10 IU/ml, considered a pathology. Not only in the detection of malignant liver tumors increased rates of AFP, sometimes it tells about the metastases that come from cancers of other organs – lung, breast, intestines. Note that in the diagnosis of liver cirrhosis, hepatitis, the AFP level increased. Pregnant women and the fetus too, there is increased alpha-fetoprotein.

The tumor marker CEA

The walls of the digestive tract of the fetus in the womb is able to produce cancer-embryonic antigen. From the moment of birth and consistent maturation, the synthesis of this tumor marker is being phased out. A person who is not sick, the blood will contain CEA, which is 0-5 ng/ml in the case where the result of the analysis shows that this level is exceeded, an urgent need to test for cancers such bodies:

  • mammary glands;
  • the uterus;
  • ovaries;
  • prostate;
  • stomach;
  • rectum;

Mechanical action leads to improved results, the rate of which in the blood of less than 4 ng/ml

The values of CA-15-3

Indicator breast cancer that has reached a late stage, is considered to be the tumor marker CA-15-3. His increased rate of 30 U/ml indicates the presence of cancer. The exception is pregnancy, when the value of tumor markers above normal. Giving blood for analysis of this type is indicated for suspected disease recurrence and metastasis following bodies:

  • endometrium, of the uterus;
  • ovaries;
  • lungs;
  • bladder;
