It is possible to get cancer even if the blood count is normal, and there is no necessary connection between cancer and the blood count. If the cancer does not affect the hematopoietic system, the blood test can be normal, therefore, a normal blood test does not necessarily mean no cancer. Blood test mainly reflects 3 main indicators: white blood cells, hemoglobin in red blood cells, and platelets. These 3 indicators are not necessarily related to the development of cancer. White blood cells are significantly elevated in infections, while hemoglobin and red blood cells decrease in anemia. In the case of tumors of the blood system, this can lead to, among other things, a decrease in platelets. Cancer mainly occurs in important organs, such as lungs, breast, colon, etc., tumors of soft tissues, these tumors show symptoms of organ involvement, such as lung cancer, there is coughing, coughing up sputum, sputum with blood, breast cancer is mainly breast lumps, so there is no inevitable connection with white blood cells or whether the blood count is normal or not.
