Does colon cancer affect white blood cell count?

The higher incidence risk associated with an increased WBC was also seen for colon cancer in women (highest versus lowest quartile: HR 1.46, 95% CI 1.20-1.78, p for trend = 0.0003) (Table 6).

Does colon cancer affect red blood cells?

Colon cancer is caused by abnormal growth of cells in the large intestine (colon). These cells often form tumors on or in blood vessels in the colon that carry red blood cells. Research suggests that these tumors can cause bleeding and a loss of healthy red blood cells, which commonly causes anemia.

Can colon cancer cause low WBC?

A person with cancer can develop a low WBC count from the cancer or from treatment for the cancer. Cancer may be in the bone marrow, causing fewer neutrophils to be made. The WBC count can also go down when cancer is treated with chemotherapy drugs, which slow bone marrow production of healthy WBCs.

Does cancer show up in routine blood work?

New research suggests that a routine blood test could help find cancers early. Researchers have previously shown that high levels of platelets – cells in the blood that help stop bleeding – can be a sign of cancer. But now they have found that even slightly raised levels of platelets may be an indication of cancer.
