Piles (hemorrhoids) are common in both men and women. By the age of 50 half of the people develop hemorrhoids to some extent. Although bleeding may occur in some cases, it does not cause any serious problem. But a person suffering from long standing bleeding piles (hemorrhoids) can have anemia. Women usually tend to develop piles (hemorrhoids) during pregnancy because of the pressure of the fetus and hormonal changes, but it is usually a temporary problem and disappears after childbirth.

Melanoma can occur on any part of the body. Primary tumors are most common on the trunk in men and on the lower extremity (thighs, legs, feet) in women. Studies have concluded that incisional biopsies of melanoma do not cause the tumor to spread locally or metastasize. See similar questions...

CWD is relatively rare. In Colorado, for example, fewer than 200 cases, mostly in mule deer, have been documented since 1981. In checking hunter-harvested animals, less than 6% of deer and 1% of elk in north-central and northeastern Colorado were found to have CWD. Similar surveillance in southeastern Wyoming also indicated that less than 7% of deer had CWD. Deer and elk checked outside these areas in Colorado and Wyoming did not have CWD.

Some of the side effects from radiation therapy (either external beam radiotherapy or prostate seed implant therapy) occur within days or weeks of the treatment and are called the acute side effects. Other side effects, known as late side effects, may not appear for six or more months after the treatment. See similar questions...

Each of us have veins around the anus that tend to stretch under pressure. An increased pressure within the abdomen (due to repeated straining at stool, pressure of fetus during pregnancy, obesity etc.) may cause the blood to stagnate and collect in the rectal veins causing them to swell and bulge out of the anal opening. These swollen veins are called as piles or hemorrhoids. See similar questions...

The answer depends on the size of the earthquake. Over the entire Earth, the number of earthquakes with magnitudes of 8 and greater is less than one each year. However, each year there are about 10 earthquakes of magnitude 7 or greater and 100 earthquakes of magnitude 6 or greater. No matter where they occur, these earthquakes are all powerful enough to be recorded by all or mostly all of the world's sensitive seismograph stations, such as UTIG's station HKT.

Occasionally people think the show is flawed because they belong in two piles at once but shouldn't be counted twice. The simplest way to think of it is to consider the grains of rice as actors, in the UK version the cast is the population of the UK, but more than one rice-actor could play you at the same time in two different piles.

Piles are simply swollen blood vessels in your back passage. They can be internal or external. Top>> See similar questions...

BSE was first observed in Great Britain in April 1985 and was officially diagnosed in 1986. By June 1990, some 14,000 cases were confirmed (out of an estimated population of 10 million cattle) in Great Britain. Since 1986, more than 185,000 cases of BSE have been confirmed in Great Britain. The epidemic peaked in 1992-93 at almost 1,000 new cases per week. Control measures have since reduced incidence of the disease, and currently fewer than 100 new cases are reported per week.

Fistula occurs when emergency obstetric care is not available to women who develop complications during childbirth. This is why women living in remote rural areas with little access to medical care are at risk. Before the medical advances of the 20th Century, fistula was quite common in Europe and the United States. Today, fistula is almost unheard of in high-income countries, or in countries where obstetric care is widely available. See similar questions...

In 2007, there are approximately 2 million people with limb loss in the United States (excluding fingers and toes). There are more than 185,000 new amputations preformed each year in this country. The prevalence rate in 1996 was 4.9 per 1,000 persons. The incidence rate was 46.2 per 100,000 persons with dysvascular disease, 5.86 per 100,000 persons secondary to trauma, 0.35 per 100,000 secondary to malignancy of a bone or joint. The birth prevalence of congenital limb deficiency in 1996 was 25. See similar questions...

Reproductive cloning involves removing all the DNA from a female egg, and the injection of DNA from an adult body cell (e.g. a skin cell). The cloning technique is called nuclear transfer, and is very similar to ICSI (intra cytoplasmic sperm injection) a procedure members of International Cloning Consortium have performed numerous times.

Sound enters your ears in sound waves. These sound waves hit your eardrum and are converted to pressure changes in the inner ear. This causes special nerves to impulse, which are read by your brain as sound. When these nerves are exposed to a surplus of pressure changes, they may become damaged. You may have noticed that if you listen to loud music for several hours that your ears "ring." This is a Temporary Threshold Shift, or a temporary reduction in hearing. See similar questions...

Withdrawal occurs when an opiate-addicted individual stops taking opioids. Withdrawal can begin in as little as a few hours after the last dose, but typically starts 12-24 hours after the last dose. A lot of times it begins with sweating, yawning, a runny nose and "teary"-eyes. See similar questions...

Conception, or fertilization, occurs when the male's sperm meets with the woman's ovum (egg) and successfully penetrates it. This typically takes place in one of the woman's fallopian tubes and the fertilized egg then travels to the uterus and implants in the uterine lining. For pregnancy to take place, fertilization of the egg must be followed by a successful implantation. Only one egg is released for fertilization in each menstrual cycle. See similar questions...

The usual causes of dehydration are a lot of diarrhoea and vomiting. Dehydration can also occur if you do not eat or drink much during an illness or if you do not drink enough during or after strenuous exercise. Medications that cause fluid loss to control excess body fluid (diuretics) are a common long-term cause. See similar questions...

The theory about this that makes most sense is called Trophotropism. The easiest way to explain this is to make a comparison to a plant. A plant will lean towards the sun to get the light it needs to survive. Since the lower segment of the uterus is not as nourishing as the upper segment, the placenta will grow to reach more nourishing tissue. The placental mass will erode away from the cervix, but the vessels can't. This also explains the velamentous insertion of the cord. See similar questions...

Your body has a natural defense system called the immune system that protects you from infection and disease. The immune system defends your body by producing "killer" cells that destroy foreign substances (such as viruses and bacteria). Since the donor organ doesn't match your old organ exactly, your body tries to destroy the transplanted organ. Essentially, a transplant creates a new disease called rejection. Rejection is nature's way of protecting your body. See similar questions...

Almost everyone is exposed to low levels of asbestos in their lives. It exists in the air at extremely low concentration; levels are highest in urban and industrial areas. These fibers are released into the air during demolition work, remodeling, or other activity in which the material containing asbestos is disturbed. Asbestos may occur in tap water where such water passes through cement pipes containing the substance. See similar questions...
