What does high blast cells mean that show up in a regular cbc? I have leukemia n can't go into remission, so I feel like my doctor has given up on me.

What does high blast cells mean that show up in a regular cbc? I have leukemia n can't go into remission, so I feel like my doctor has given up on me.

Consult: I'm sorry about your illness. Some types of leukemia are often curable; others are not. The fact that you have written tells me that this is time for a review by a second specialist in leukemia -- not because I suspect error, but because communication may have broken down. You have an absolute right both to clear answers (outlook, options) and to feel cared-for regardless of your illness's course. ...Read more

Leukemia (Definition)

A malignant hematologic neoplasm that originates in the bone marrow and represents a clonal proliferation of hematopoietic elements belonging to any of the myeloid, lymphoid, erythroid, and megakaryocytic lineages. Of note, other hematologic neoplasms like lymphoma or myeloma may demonstrate a leukemic phase without actually originating in the bone marrow ...Read more

Would a CBC always show leukemia, if you have leukemia?

Would a CBC always show leukemia, if you have leukemia?

Usually.: The cbc, or complete blood count measures the normal cellular components of blood, red cells, white cells and platelets. Leukemia is detected by either there being abnormal cells in the blood, or a reduction in the normal elements. Very early on in the development of leukemia, there might not be enough damage to the bone marrow for the normal elements to be effected or abnormal cells to be found. ...Read more

What happens if my son had leukemia, what would the CBC show?

What happens if my son had leukemia, what would the CBC show?

Pancytopenia: Usually, patients with leukemia have low white blood cell, red blood cell, and platelet values - called pancytopenia. Sometimes, white blood cell counts will be elevated - this happens when normal white blood cells are replaced by leukemia cells. Some CBCs will report concerning cells types, but abnormal white blood cells should be examined under a microscope with Oncology referral as necessary. ...Read more

Would a CBC show lymphoma or leukemia?

Likely for leukemia: Oftentimes leukemias can be picked up on routine CBC since it is a cancer of the blood and causes abnormal values of your red and white blood cells to appear. Lymphomas do not always affect the blood in a way that would be picked up on cbc. All leukemias however will not be picked up on routine CBC and CBC alone will not tell you what kind of leukemia specifically one might have. ...Read more

How long it will will take for acute and chronic leukemia to develop in the body before they can be found on cbc or show symptoms,,,, months or years?

How long it will will take for acute and chronic leukemia to develop in the body before they can be found on cbc or show symptoms,,,, months or years?

Indeterminate: It is not feasible to say, for a normal person, how long it will take for the person to develop leukemia. Vast majority of the people never get one.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.

Can a CBC (blood test) show leukemia always?

Can a CBC (blood test) show leukemia always?

Yes, most times: A leukemia typically begins in the bone marrow and will often show effects on the CBC as the cancer cells spill over into the circulating blood. On rare occasions leukemia may be still limited in the bone marrow, so we make a diagnosis by taking a bone marrow sample. ...Read more

Could a CBC (blood test) show leukemia accurately always?

Could a CBC (blood test) show leukemia accurately always?

Sometimes: Sometimes but not always. Leukemia, a form of blood and bone marrow cancer, is frequently detectable in the blood; however, especially if early in the course of the disease, leukemic cells may be confined to the bone marrow and not cross into the blood in sufficient numbers to be detected by a cbc. Ultimately, the complete diagnosis and prognosis of leukemia relies on bone marrow examination. ...Read more

Can I have a normal CBC and still have leukemia? I have all the symptoms but blood seems fine but is it possible to only show up on a BMB and not blood

Not leukemia: Normal CBC proves you don't have leukemia. Anyway, there are no "symptoms" of leukemia. Most cases cause no symptoms at all; or nonspecific symptoms that go along with a hundred other conditions. Check back with your doctor if you remain concerned. Good luck! ...Read more

I am trying to figure out if my CBC shows me having some kind of leukemia. Wbc is 12.5 lymphocyte 3.5 monocytes 1.1 neutrophils normal?

Review the smear: At age 31 this is a very unusual group of absolute white cell counts. I'd get with your physician and find out whether the cells all appeared normal. This may be an inexperienced or inept technician's interpretation of a smear from infectious mononucleosis. If you FEEL well, I'd urge the bloodwork be repeated, and if still very abnormal, a hematology consult. ...Read more

11yr old son CBC shows high lymphocyte % and low MPV, low CREAT, and high Alkaline PHOS. Symptoms of fatigue, pale skin, headache, rashes- leukemia?

Stop worrying: Percentages are meaningless. All that matters is absolute counts of lymphs and neutrophils. All 11 year olds have high alkaline phosphate. Mean platelet volume means nothing. Low creatinine is never a first warning. If he's not anemic and there are no abnormal cells noted, stop worrying about leukemia. The most common cause of headaches in a boy his age is needing glasses. ...Read more

Would a CBC help diagnosis leukemia?

Yes it would: Leukemia is a cancer of the white blood cells, so the white blood counts are effected by leukemia, usually they increase but sometimes they can go down too. Also the hb and platelet counts are also affected by leukemia as it grows in the bone marrow and can compromise the production of all types of blood cells. So a CBC is a good screening test for leukemia diagnosis. ...Read more

What does your CBC have to be in order to be diagnosed with leukemia?

WBC abnormality: In leukemia, patients typically have avery high WBC (white blood cell count), which is one of the results that comes in a CBC (complete blood count). Sometimes though, WBC counts only mildly elevated. Several other parameters included in the CBC, like hemoglobin, and platelet count can also be abnormal. The clinical history and symptoms as well as additional testing will lead to the diagnosis. ...Read more

If someone got a CBC in february is it possible to have developed leukemia between then and now? How long does it take for leukemia to develop?

Possible: The leukemia was likely in process in february, but was not detectable in a cbc, and has advanced enough to be detectable now. The time of onset of tumors including leukemias is generally indeterminate, you can only pinpoint the time when the tumor/leukemia becomes detectable. The underlying process has usually been in play for years. ...Read more

Likely not say more: Your weekly cbc tests seem unusual but along the way, ask the doc to make a blood smear and check your cells. That would be a good start to see if you need more specific tests, like a viral test since your lymphocytes count varIes and fatigue, may indicate infection, say mononucleosis, but if the peripheral bood smear shows really bad cells, more than those seen in infections, See blood docs.

CBC Utility: 1. Leukemia & lymphoma make up a huge and diverse number of different disease states.
2. These can be pre-symptomatic or advanced or in between. 3. The complete blood count (CBC) can be abnormal & there is NOT cancer (eg high WBC with UTI or pneumonia). 4. The CBC can be normal and a cancer is present. 5. Cancer diagnosis depends on many things. CBC may help along with more specialized tests. ...Read more

Had cbc. 34yo male. Dad had leukemia. All in range except monocytes % was 3.6l. Monocytes # was 0.3 in range. Should I worry leukemia or anything else?

Had cbc. 34yo male. Dad had leukemia. All in range except monocytes % was 3.6l. Monocytes # was 0.3 in range. Should I worry leukemia or anything else?

No,,: It is common for some individual values to be out of range sometimes. This isn't too low also. What would be worrisome is a consistent pattern of abnormal results. If there were excessive monocytes and blast (immature) cells, for example, that'd be a serious result requiring more tests. This isn't anything like that and there're no other symptoms and signs so it should be fine. Good luck. ...Read more

While the most common is blood loss from bleedig, the source must be found. Anemia may be a first sign of leukemia or lymphoma, but not very likely. Women lose blood menstrually.

Wait to worry: You need to tell us your medical history such as why did you have your blood tested in the first place? Your platelet count is slightly high but it is within a safe range at present. If it rises further to a level above 5, 00, 000, you will need to have a blood specialist (Hematologist's)opinion and further testing to find the cause. ...Read more

It's a good screen: Yes, a CBC is an excellent screen to see if you have any abnormalities in your red or white blood cells. However, you can actually save money if you have a good primary care physician who will listen to your concerns and order the appropriate tests based on your symptoms, and give suggestions on staying healthy. If you are having night sweats and wt loss it could also be due to hyperthyroidism.C. ...Read more

Can someone please explain bone pain in leukemia? If CBC blood work was normal, can I still. Have leukemia?

Leukemia...: Leukemia is an uncontrolled proliferation of malignant cells in the bone marrow. The marrow is composed of bone with marrow spaces. In leukemia, these marrow spaces become overpopulated by leukemic cells which compress the normal bone marrow structures, causing pain. Rarely, the cells cannot get out of the marrow and the WBC/CBC will be normal: an aleukemic leukemic. Hope this helps! ...Read more

What's the difference between a CBC and a cbc/w differential? I had the CBC with diff can this see for blood cancers leukemia. Lymphoma etc

CBC is a short: Hand that confuses. It looks at the red blood cell count and white blood cell count and commonly describes hemoglobin, hematocrit and mchc, MCV indices to guess at anemia cause. The differential segregates the white cell count into neutrophils and lymphocytes. If normal, you don;t have leukemia. If not, marrow and closr analysis necessary. ...Read more

Need to examine: It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor. Leukemia is unlikely if there are no other symptoms. If you are overweight, it may help to lose weight (easier said than done).
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats.
