8. Anemia is prevalent in colon cancer blood tests
We mentioned above that colon cancer leads to blood vessels’ growth, and they are sometimes very fragile and prone to bleeding. Gastrointestinal bleeding is sometimes not noticed by patients, and they only find out after seeing their blood test results. Anemia is prevalent in these cases. It is a reduction of hemoglobin levels in the blood, which carries oxygen to our tissues. Thus, it is often associated with feeling weak and tired all the time.
Actually, anemia is a ubiquitous finding in asymptomatic colon cancer patients, and it should be studied thoroughly, especially in patients older than 50 years or those with a predisposition for colon cancer.
