What are oncarkers, and how to determine cancer by them?

If the tumor begins to grow, it distinguishes specific proteins, unlike the rest of our body. In medicine, these proteins are called cancer markersAnd they are different for different tumors.

Diagnosis of cancer on blood tests for cancer markers has not yet been completely studied, and does not give 100% result. At the initial stage of cancer formation, the method is rarely used for the following reasons:

• High cost of analysis
• It does not always give reliable results, sometimes the presence of oncomarkers in a healthy body can show

Most often, an analysis for cancer is prescribed with a repeated manifestation of symptoms of cancerto control the patient's condition after surgery or treatment. Blood for analysis is taken every 3-4 months.

Raising oncomarkers, and organs where they are most often formed:

• AFP - at alcoholics; With cirrhosis.
• Antigen REA - an increase means that there are inflammation in the bladder, liver, uterus, intestines, lungs; With prostate adenoma.
• B-2-mg-with kidney diseases.
• Sa-125-in the uterus, ovaries with inflammation; the mammary gland with tumors; before menstruation; During pregnancy.
• Sa-19-9-in the stomach, colon, pancreas and gall bladder.
• Sa-15-3-with breast cancer, during pregnancy.
• SA-242-cancer in all stages: stomach, pancreas, gall bladder, rectum.
• CA-72-4-breast cancer.
• Cyfra-21-1-cancer of the light and bladder.
• NO-4-with ovarian cancer.
• NSE - with skin cancer.
• PSA - prostate cancer in men.
• HCG - with bladder cancer.
• HCG+AFP - with egg cancer in men.

Attention. Scientists have not yet found on the brain cancer.

How is blood on cancer markers?

To make an analysis for oncarkers correct, you need to prepare for blood donation:

• 2-3 weeks before blood donation, do not take any drugs.
• 2-3 days before donating blood, do not drink alcoholic beverages, do not have high-calorie, fatty and fried food.
• Do not smoke 1-2 days.

• Poor coagulation
• Reducing platelets
• Immature blood cells appeared

Important. If the above -based symptoms are observed when donating blood for a general analysis, this may indicate other diseases.

How to determine cancer on a biochemical blood test?

By biochemical analysis, you can also learn about the beginning of cancer development in the body. But the same reasons indicate other diseases. These are the following signs:

• Increasing blood sugar - with diabetes and pancreatic tumors
• Increasing bilirubin - when blocking the gallbladder and with liver cancer
• Improving urea
• Decrease in proteins
• Increased number of alkaline phosphatase
