Many patients ask this question. The answer is sometimes, but usually not. There are many non-cancerous reasons to have blood in the stool such as hemorrhoids, polyps, or fissures. However, any adult individual who sees blood in their bowel movements should consult their doctor for an examination. You can't tell what the cause is without having a look inside. If there is any concern, a full colonoscopy is usually advised. The point is that all bleeding in adults must be evaluated.

Blood in a pet?s stool may indicate several things. Perhaps it is a minor irritation in the large intestine that could clear up in a day or Canine parvovirus or poisoning. It is a good idea to bring the pet in for an examination to determine the actual cause and appropriate treatment. See similar questions...

Frank red blood could mean an irritation to the large bowel. Tarry black stool could indicate digested blood from higher up in the GI tract (the small intestine). Any time you see blood it is a good idea to have your pet checked over by your vet. Bring a sample of the stool to your veterinarian for examination for internal parasites. Not all parasites are visible to the naked eye—most often the eggs (ova) are found under the microscope. See similar questions...

In the United States, this is found mostly in the Boston, MA area. It means that an all-pedestrian phase is in effect, and no cars are going thru the intersection. It was implemented before pedestrian signals came into use. If you are driving and see this, stop. Photos of this phase in use are at http://www.massroads.com/gallery.php?page=red_and_yellow . In some European countries, red-yellow precedes green and often coincides with the yellow phase for cross traffic. See similar questions...

An insufficient blood result refers specifically to the Home Access® Hepatitis C Check Test system. It means that the Hepatitis C test could not be performed on the blood sample that was sent to the laboratory. This happens most often because there was not enough blood to test, there were white spots in the circle, or the blood did not soak through all the way to the back. See similar questions...

No, additional imaging is quite routine. It does not necessarily mean that you have cancer. It is another way of imaging the breast so that the radiologist can see things in the breast in a slightly different manner. See similar questions...

The line of blood is a collection of genetically transmittable characteristics (morphological and of character), that in a breed identify the fruit of an aimed selection. In one breed therefore coexist innumerable stocks with very different characteristics, but always remaining in that type. Not always a breeding succeeds in obtaining its own line of blood, this is in fact a goal to aim in order to make possible the identification of the origin of a subject, without reading the pedigree.

No, even though a gene mutation may be present, you are not at 100% risk for developing cancer. An individual with a BRCA1 and/or BRCA2 alteration is more likely to develop cancer than an individual without an alteration. However, not every individual who has a BRCA1 and/or BRCA2 alteration will develop cancer, because genes are not the only factor affecting cancer risk. See similar questions...

Stage is the word doctors use to describe the size of a cancerous tumor as well as where and how far it has spread. The stage of the cancer affects the choices for treatment. See similar questions...

The meaning depends on the particular medication that you are taking. In some brands, it means the medication is defective and that you are not getting it's intended benefits. You should contact the manufacturer to find out if this is a problem with your particular brand. If it is a problem, return the remaining guai to them for further testing. They cannot fix a problem if they don't know that it exists. Back To Top See similar questions...

These changes are the new proposal that will completely replace the old proposal. This is INSTEAD of the other changes, not in addition to them. See similar questions...

In normal healthy persons there is a slight drop in blood count (not enough to be noticed) which returns to normal levels within 3 - 4 weeks. During this time the donor must be receiving adequate amounts of dietary iron (needed to make hemoglobin, the protein that carries oxygen and gives blood its red color). See similar questions...

Normal red blood cells are deformable but many conditions of disease and trauma can reduce their deformability. Red blood cells with reduced deformability will have difficulty forming layers at high shear rates. In the quiescent state cells with an extreme diminishment of deformability will also have difficulty aggregating. See similar questions...

a result of changes in plasma protein concentrations and the influence of certain diseases, the tendency of red blood cells to aggregated can be enhanced or diminished. The figure at right shows an idealized example of how altered aggregation tendencies can affect viscoelasticity. The viscosity and elasticity of blood with low aggregation tendencies (RED) are below the values for normal blood (BLUE) at low shear rates. See similar questions...

You and your baby will not be listed on the NMDP Registry. Only the cord blood unit will be listed. The collected cord blood unit will be given a number at the hospital. This is how it is identified on the NMDP Registry and at the public cord blood bank. No name is associated with it. See similar questions...

When these or other symptoms occur, they are not always caused by cancer. They may also be caused by infections, benign tumors, or other problems. It is important to see the doctor about any of these symptoms or about other physical changes. Only a doctor can make a diagnosis. See similar questions...

The WHI DM Trial was not designed to examine specifically the effects of vegetables and fruits, and the low-fat dietary pattern (the intervention) focused more on decreasing total fat intake. For cancer prevention, the WHI dietary pattern suggested a possible small benefit for breast cancer, but no benefit for colorectal cancer. See similar questions...

Only 20% of lumps are found to be cancerous. It is normal for your breasts to feel slightly lumpy or uneven. It is important to conduct self-examinations while you are young so that you know what your healthy breast feels like. Therefore, you will notice any irregularities at a later time.
