What is the reason of high carbohydrate antigen 125

summary

Many women who suffer from breast cancer or ovarian cancer can often hear the word carbohydrate antigen, but many people do not understand the meaning of carbohydrate antigen. Here, I'd like to talk about the reasons for this situation, hoping to help you.

What is the reason of high carbohydrate antigen 125

Reason 1: when a woman has cancer, her own carbohydrate antigen will rise. Generally, when the carbohydrate antigen rises, it means that the cancer cells expand or the cancer begins to deteriorate.

The second reason is that the level of serum carbohydrate antigen in patients with ovarian cancer increased significantly, while that in patients with effective chemotherapy and surgery decreased rapidly. If there is recurrence, the increase of carbohydrate antigen may precede the clinical symptoms.

The third reason: other non ovarian malignant tumors also have a certain positive rate, such as 40% of breast cancer, 50% of pancreatic cancer, 47% of gastric cancer, 44% of lung cancer, 32% of colorectal cancer, and 43% of other gynecological tumors. For patients with lung cancer, the positive rate of CA125 increased with the progress of lung cancer staging. Clinical studies showed that the positive rate of stage I, II, III and IV was 7.8%, 18.6%, 32.5% and 53.9%, respectively, and the overall positive rate was 26.9%.

matters needing attention

In the examination, if the carbohydrate antigen is significantly increased, we should pay attention to the deterioration of cancer.
