My MCH blood test always comes back slightly high is that enough of an indicator along with thickening of the cecum to suspect cancer?

My MCH blood test always comes back slightly high is that enough of an indicator along with thickening of the cecum to suspect cancer?

Mean: Corpuscular hemoglobin associates with large cells, and b-12 or folate (folic acid) deficinency. Low MCV (mean corpuscular volume) or microcytosis is associated with iron deficiency, like from blood loss into the cecum. Heavy menses, lack of red meat in diet without supplemental iron. Sounds like you had a ct too. ...Read more

Cancer (Definition)

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

Can a blood test detect cancer?

Can a blood test detect cancer?

Only a few cancers: Unfortunately, there are very few cancers that can be detected through blood tests. These include prostate cancer and leukemia. Some other cancers have tumor marker tests, such as breast cancer, ovarian cancer, colon cancer, pancreatic cancer, and others but these are to monitor, not detect the cancer. ...Read more

What kind of blood test is there for cancer for women?

No screening blood: There is no blood test specifically for cancer. Women are screened with mammograms, cervix pap smears, colonoscopy, and physical exams. When there is suspicion or actual diagnosis of cancer there are some blood tests and tumor markers that can be useful. ...Read more

Is there a blood test for cancer?

Not quite: Cancer is not one disease but a conglomeration of multiple disease. Some cancers, e.g., leukemias, multiple myeloma, and some advanced cancers can be detected by blood tests. However there are different tests for even these categories of cancers. ...Read more

What blood test detect testicular cancer?

What blood test detect testicular cancer?

Usually an adept: Hand examining the scrotum is the beginning, but you are likely referring to Alpha -feto-protein (embryonal and yolk sac tumors) and HCG (human chorionic gonadotropin) choriocarcinoma, germinoma, and teratoma. Seminoma may not produce either, and never afp. These occur in all ages, but especially young men teens and twenties. ...Read more

Can they detect ovarian cancer through a blood test?

Can they detect ovarian cancer through a blood test?

Backward: There is no screening test for ovca. However, if you have ovarian cancer, a ca-125 level may or may not be elevated. If it is, it may be one thing monitired for response. Getting ca-125, an expensive blood test of unproven value before knowing you have the cancer is inded backward, costly, non-specific and can led to unnecessary worry. ...Read more

Is it possible to find cervical cancer through a blood test?

Is it possible to find cervical cancer through a blood test?

Mostly no: There are no reliable blood markers for cervical cancer. The tumor marker ca125 is often an indicator of ovarian cancer, but it is not very sensitive and not very specific. It is used as a screening test in some circumstances, and to follow the effects of therapy when it has been documented to be high at the start. There are no blood markers that are good for endometrial cancer, either. ...Read more

Which body/blood test is the best test for cancer in the body?

None of them: None of the routine labs are a general cancer screen. There are some "alternative and holistic" practitioners that offer supposed blood tests for general cancer, but these don't meet scientific standards and haven't stood up to horst testing. ...Read more

Possibly: Honestly, it would depend on the specific cancer and where and if it has spread to other sites. For instance, melanoma would likely have a normal count but leukemia would not. ...Read more

Would blood test be able to find testicular cancer before you can feel it?

Would blood test be able to find testicular cancer before you can feel it?

Sometimes: Some types of testicular cancers produce substances that circulate in the blood and can be detected with simple blood tests. Not all do, however, and one would usually not do a blood test if there was no mass or abnormality in the testicles. ...Read more

Can a blood test tell if someone has cancer or not? Or are x-rays the only way to tell?

Can a blood test tell if someone has cancer or not? Or are x-rays the only way to tell?

Rarely.: Cancer requires a pathologic diagnosis. That means someone has to look at tissue under a microscope to determine if something is cancer. Leukemia is a cancer of the blood cells, and it can sometimes be diagnosed just by looking at the blood. But other types of cancer require a biopsy of a suspicious lump or mass. Xrays and blood tests can suggest the diagnosis, but only a biopsy can say for sure. ...Read more

I'm just wondering, if you get a standard blood test and urine sample can it detect cancer?

I'm just wondering, if you get a standard blood test and urine sample can it detect cancer?

No: You'll need a good history and physical. Some lab abnormalities may tip the physician off to cancer. There are some screens -- colonoscopy, mammography, Pap smears, some others -- that can seek cancer while it's curable. ...Read more

Blood test reveals a CEA level of 7.6ug/l. Never had cancer that I know of. I am a smoker 50yrs of age, female?

Blood test reveals a CEA level of 7.6ug/l. Never had cancer that I know of. I am a smoker 50yrs of age, female?

Don't screen w/CEA: Cea (carcinoembryonic antigen) is not meant to be used as a screening test for cancer as many cancers don't produce it and smoking can raise the value, leading to unwarranted worry and further invasive testing to dispel said worry. Check out http://labtestsonline. Org/understanding/analytes/cea/tab/test for more info, especially it's proper use & role. ...Read more

Can you tell me what you suggest if ESR blood test result is very high (for female over 50years is 85))can cause cancer?

Can you tell me what you suggest if ESR blood test result is very high (for female over 50years is 85))can cause cancer?

Just a number: Sed rate is useful in diagnosing a handful of uncommon diseases and in my opinion is overused. Many older folks have a high sed rate and no explanation is ever found. It's also not something you can treat. I suggest you forget about it and maintain normal vigilance against cancer like any other sensible person. ...Read more

I have all the symptoms of ovarian cancer. Had a blood test and it was negative and my scan turned out negative too. So what is the matter?

Ovarian cancer: More often than not, ovarian cancer does not have symptoms. If your scan and blood tests are negative, obviously one must consider other causes. If you separately list your symptoms here, we might be able to help. Even better might be a consult via HealthTap Prime or Healthtap Concierge. Whatever we can do to help. Good luck. ...Read more

Blood tests cant tell if u have cancer but Can cancer be ruled out from blood test? If your cell counts are normal does that mean you're cancer free?

NO: Blood cell counts gives you clues only and that is when the. Cancer is advanced. ROUTINE blood counts and blood chemistry can be normal when cancer is in its early stages. That is why we use screening tests to detect early cancer ...Read more

Would blood tests show cancerous tumors, or even benign one's in the body? OR Would a regular blood test show indications of cancer / a tumor inside?

Would blood tests show cancerous tumors, or even benign one's in the body? OR Would a regular blood test show indications of cancer / a tumor inside?

Not very helpful: We don't have reliable blood tests to look for the common cancers. Your best bet is cancer surveillance (in your case, I trust you get pap smears if you have ever had someone special), and know the usual warning signs and get seen if they come up. ...Read more

Is there a blood test to r/o cancer?

Is there a blood test to r/o cancer?

No.: There is no one blood test that screens for all cancers. There are specific tests that can be used to monitor disease status in particular diagnoses such as psa for prostate cancer, ca125 for ovarian cancer or CEA for colon cancer, but these tests are not so good for screening a general population. The concern with them is either lack of specificty or detection of lesions that are not risky. ...Read more

Is there a blood test to detect any/all cancers?

Cancer screening: There are blood tests that can screen for certain types of cancer, but they do not necessarily prove that there is cancer, even if abnormal. You should discuss your concerns with your family physician to see IF there is a particular test that you might benefit from having done. There is no value in doing a routine series of tests if there is no indication that they are needed. ...Read more

Is there a blood test that can indicate if someone has cancer?

Is there a blood test that can indicate if someone has cancer?

Yes: Yes, but it is not that straightforward. It is most appropriately used when you know somebody has cancer, the cancer has been treated, and you are looking for regrowth of the cancer. Using the tests any other way can be very misleading. It also depends on what kind of cancer you have (ldh, afp, thyroglobulin, cea, ca19-9, ca 125, and chromogranin are all examples). ...Read more

How would you know if you have cancer? Is there any signs? Would a blood test show if you hsve cancer?

How would you know if you have cancer? Is there any signs? Would a blood test show if you hsve cancer?

No: Cancer is not one disease, but there are multiple types of cancers that affect multiple organs. There is no blood test for a generic diagnosis of cancer. The signs and symptoms of different cancers vary and there is no pathognomnic sign or symptom either.
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.
Practice safe sex, if you have sex. ...Read more

Would a complete patient profile blood test show cancer?

Would a complete patient profile blood test show cancer?

Maybe not: There is no standard "complete patient profile blood test" in the U.S., so what is tested for depends on what a doctor is looking for. A blood chemistry test such as a Comprehensive Metabolic Panel looks at 14-17 items, but isn't looking for cancer. It will, however, detect some side effects of having a widespread cancer problem. Cancers come in all sizes and many types, but need specific testing. ...Read more
