Collectively grouped under the Ewing sarcoma family of tumors, Ewing's sarcoma is the second most common primary bone cancer occurring predominantly in children and in adolescents. Very rarely is it experienced in adults above the age of 30.

Typically forming in the bones of the chest, pelvis, head, back or trunk and in the long bones of the arms and legs, Ewing's sarcoma is believed to originate in certain kinds of primitive cells. When it begins to affect similar kind of cells found outside the bone, it is usually called an extraosseous Ewing's sarcoma.

Causes
1. Similar to all types of Ewing tumors, Ewing's sarcoma is generally caused by an alteration in a certain cell compelling a gene named EWS found on chromosome no. 22 to move over to a DNA section on any one of the surrounding chromosomes resulting in the activation of the EWS gene.
2. While it is not a hereditary condition, it usually occurs after childbirth, but no substantial evidence has been found as to why it happens so.

Symptoms
Symptoms of Ewing's sarcoma may include:
1. Swelling and pain especially in the arms, legs, back, chest or pelvis
2. Swelling accompanied by joint immobility
3. A bone breaks having no apparent cause
4. Swelling which may or may not be accompanied by a warm, tingling sensation
5. Fever resulting from unknown causes
6. Lumps or bumps which do not subside over time
7. Abnormal weight loss
8. High levels of fatigue
9. Tumors which have spread over to the lungs may cause shortness of breath
10.Tumors spread over to the spine may cause weakness or even paralysis.

Because the symptoms of Ewing's sarcoma can hardly be distinguished from symptoms caused by other infections or injuries, an early diagnosis is absolutely necessary for a successive treatment.

Causes and Symptoms of Ewing's Sarcoma

Brain mapping is a technique where the biological quantities of a human brain are represented as spatial quantities resulting in maps. As with many other medical technologies, brain mapping is fast-evolving as well. Among several uses, brain mapping is chiefly used while performing surgery on the brain.

When surgery is to be performed on the brain such as surgery for epilepsy, the surgeon would want to comprehend how the brain areas are affected by seizures. The surgical intervention is meant for removing as much as seizure focus as possible while preserving crucial functions like understanding, speech, vision, movement, and sensation.

Why is brain mapping performed?
Brain mapping is a process which helps in identification of functions of various parts of the brain. Mapping the brain by stimulating different areas of the brain areas can aid in creating a map for a particular person. The map allows the doctor in understanding what parts of the brain are responsible for performing critical functions including sensation, movement, speech and other functions.

Which functions of the brain can be mapped electrically?
Typical areas of the brain which have motor, language, visual and sensory functions are needed to be mapped. When current is applied to a single area at a time, the doctor understands which part of the brain is responsible for which function.
When the patient is not able to speak due to the current, then the area is likely to be crucial for language function. If the limbs, face or trunk of the patient stop moving as the current passes, the area that is tested is responsible for movement. On the other hand, if the individual experiences tingling, numbing, and other sensations when the current is applied, it means that a sensory region is discovered.

How is electrical brain mapping performed?
Electrical brain mapping for guiding brain surgery for epilepsy can be performed in two distinct processes: directly during the surgery or in a two-stage procedure.

Two-stage procedure:
In the first stage of the process, the surgeon creates an opening in the skull which helps in exposing the surface of the brain. Small electrical contacts or electrodes are placed on the brain surface even though no brain tissue is removed. As soon as the electrodes are in the right position, the scalp is closed. The electrodes not only record the seizure of the patient electrically but also allow mapping of various areas of the brain. The last stage is surgery where abnormal brain tissues are removed.

Brain mapping process during surgery:
Electrical brain mapping may also be performed during the surgery which exposes part of the brain. This is termed as intraoperative brain mapping since it occurs while performing the main operation. The process of mapping may last for an hour to several hours at a stretch.

Brain mapping is also used to diagnose neurodegenerative diseases like Alzheimer s and Parkinson s. In these cases, the brain map shows extreme shrinkage of the brain due to tissue loss.

Brain Mapping Surgery - Why It Is Performed?

Kidney Cancer, more commonly known as renal cancer, first presents itself in the lining of the kidney. It then grows malignant and forms a tumor. The good news is that renal cancer rarely spreads to other organs. The bad news is that the tumors grow quite large before they can be detected.

Causes-
Kidney cancer has been found to occur most often in people who are older than 40 years of age. Though the cause of the cancer is not definitively known, there are a few factors that might increase the risk of developing kidney cancer. These include-

1. Obesity- Obesity can cause hormonal changes which in turn can increase the risk of cancer.

2. Smoking- As with any other kind of cancer, nicotine consumption, in the form of smoking cigarettes, increases the risk of developing the disease. In the case of renal cancer, it can, in fact, double the chances.

3. Pain Medications- A prolonged use of pain relievers over a period of time can increase the risk of renal cancer. Certain components of the medication can lead to kidney damage.

4. Genetic history- A medical history of family members, especially siblings, with the disease can significantly increase the risk of kidney cancer.



Symptoms-
In its early stages, kidney cancer remains asymptomatic, but as the tumor grow in size, symptoms begin to present themselves. These symptoms might include the following-

1. Blood in the urine.

2. A gradual loss of appetite leading to weight loss.

3. A persistent pain in your abdomen in conjunction with a lump.

4. A fever that is neither a result of an infection nor a cold, and one that lasts for weeks.

5. Swelling of the legs and ankles.

Treatment
Treatment for kidney cancer will depend on the size and location of the tumour and whether it has spread to other organs or parts of the body. Therefore, to determine the stage of cancer, diagnostic tests such as biopsy, are performed along with urine and blood tests. After determination of your cancer stage, the doctor will perform either a radical or a partial nephrectomy, where the cancerous tumor is removed along with additional tissues. Often, kidney surgery is followed by kidney transplant if both the kidneys need to be removed in nephrectomy. However, if nephrectomy does not cure your kidney cancer, then your oncologist may recommend cryotherapy, radiofrequency ablation or arterial embolization.

Kidney cancer in its advanced stage is often treated with either biological therapy where your body s immune system is utilized to fight cancer cells or targeted therapy where drugs are used stop the multiplication of cancer cells by blocking their signals. Due to such advancement in cancer treatment, the rate of success has gone up in recent years but you also need to follow a healthy lifestyle to make sure that the treatment can bring out the desired positive outcomes.

Kidney Cancer - What Causes It?

A set of cartilage discs present between the vertebrae, ensures that the spinal column can withstand the weight of the upper body. If these discs tear or get injured, the condition is commonly known as slipped disc. In medical terms the same condition is known as prolapsed intervertebral disc. Here is a look at the causes, symptoms and treatment for this painful condition.

Causes for Prolapsed Disc
Intervertebral cartilage discs undergo normal wear and tear with age. However, there are other underlying causes for a slipped disc.

Sitting for prolonged period of time may lead to the disorder
Repeatedly lifting weight in such a manner that all the pressure is exerted on the vertebrae may also lead to a prolapsed intervertebral disc. Example   Exercising with incorrect posture
Alcohol consumption and smoking
Sedentary lifestyle and lack of exercise
Accidental trauma to the spinal region
Diet not consisting of all the essential nutrition
Family history of the same condition
Tweaking one s lifestyle is generally enough to ensure that people are not affected by the condition.

Symptoms of prolapsed intervertebral disc

Patients claim to feel pain radiating from their spinal region to the calves of their feet. This sciatic nerve may get compressed due to the disorder, leading to such a pain.
Tingling sensation in the lower and upper back regions. This sensation may also spread to the arms and legs.
Patients complain of a weakness or numbness in the buttock area, feet and legs.
Treatment for prolapsed intervertebral disc

Limited activity is advised after diagnosis, but complete bed rest is not recommended.
Ice packs should be applied at first. After the pain resides, heat should be applied on the region.
Physical therapy and certain exercises are prescribed by the physician
Anti inflammatory drugs can help control the condition and relieve some of the pain.
Surgery is considered only if the condition does not subside after 4-6 weeks. However, such a surgery is risky and may cause permanent nerve damage.
If you feel that you are at risk of prolapsed intervertebral disc, consult a physician immediately. Follow the recommendations of the doctor, so that you do not have to go through the pain associated with the condition.

Prolapsed Disc - What Causes It?

Liver cancer is when the cells in the liver grow uncontrolled. As the liver filters blood from all parts of the body, one of the most common reasons for liver cancer is perhaps metastasis, which is spread from other parts. Through the blood, cancer cells from other parts reach the liver for filtration and can then make the organ cancerous.

In addition to this, there are other risk factors that can lead to liver cancer. For example, people suffering from obesity, alcohol and tobacco abuse, viral hepatitis (B or C), chronic liver disease (especially in men, who are more prone than women to develop cancer), cirrhosis and someone who has a history of a prolonged use of steroids can suffer from the disease. Also, while liver cancer is very rare in the Americas, it is very common in Africa and Southeast Asia as the prevalence of hepatitis is higher in these regions.

When it comes to the symptoms, it s acceptable that liver cancer is insidious, and the exact point of origin cannot be identified. It continues to grow until symptoms become evident, which are also nonspecific. Before analyzing your health on your own, it s always recommendable to seek an expert s final word on it. Let s take a look at the top signs that might point out towards liver cancer.

Abdominal pain: When you suffer a strong pain in the abdominal area, especially in the upper portion on the right side, it can signal a lump or a growing tumor in the liver. This can also be accompanied by middle or lower back pain.
Weight loss: Many a time, women who suffer from a sudden loss of weight can be going through a deadly disease like this one. In most cases, these weight loss cases show no attempts on the patient s side, that is, the weight loss occurred for unknown reasons. A loss of appetite, without any reasons, is another indicator. These can result due to unexplained reasons and should be taken seriously.
White, chalky stools:This one is another tell-tale sign of liver cancer. Often, people tend to ignore stools in light, flaky colors. It is always better to consult a doctor, as you might be ignoring a sign of potential cancer.
Bloating: When you feel certain heaviness or bloating in the upper part of the abdomen due to fluid accumulation it indicates, which is one of the indicators for testing liver cancer.
Frequent body conditions: Apart from the above mentioned symptoms, one can also consider personal health history when facing any liver-related problems. Recurring severe nausea and vomiting and general signs of lethargy and weakness can also indicate liver cancer. Also, personal health history with claims the patient suffered from jaundice (due to the accumulation of bile pigments in the sclera and skin) can also be taken into consideration.

Definition

Uterine fibroids are noncancerous growths of the uterus that often appear during childbearing years. Also called leiomyomas (lie-o-my-O-muhs) or myomas, uterine fibroids aren't associated with an increased risk of uterine cancer and almost never develop into cancer.

Uterine fibroids develop from the smooth muscular tissue of the uterus (myometrium). A single cell divides repeatedly, eventually creating a firm, rubbery mass distinct from nearby tissue. Fibroid location, size and number influence signs and symptoms:

TYPES

 	Submucosal fibroids: Fibroids that grow into the inner cavity of the uterus (submucosal fibroids) are more likely to cause prolonged, heavy menstrual bleeding and are sometimes a problem for women attempting pregnancy.
 	Subserosal fibroids: Fibroids that project to the outside of the uterus (subserosal fibroids) can sometimes press on your bladder, causing you to experience urinary symptoms. If fibroids bulge from the back of your uterus, they occasionally can press either on your rectum, causing a pressure sensation, or on your spinal nerves, causing backache.
 	Intramural fibroids: Some fibroids grow within the muscular uterine wall (intramural fibroids). If large enough, they can distort the shape of the uterus and cause prolonged, heavy periods, as well as pain and pressure.

Symptoms

In women who have symptoms, the most common symptoms of uterine fibroids include:

 	Heavy menstrual bleeding
 	Prolonged menstrual periods - seven days or more of menstrual bleeding
 	Pelvic pressure or pain
 	Frequent urination
 	Difficulty emptying your bladder
 	Constipation
 	Backache or leg pains

 	Abnormal menstrual bleeding, such as:
o	Heavier, prolonged periods that can cause anemia
o	Painful periods.
o	Spotting before or after periods.
o	Bleeding between periods.

 	Pelvic pain and pressure, such as:
o	Pain in the,abdomen pelvis, or low back.
o	Pain during sexual intercourse.
o	bloating and feelings of abdominal pressure.

 	Urinary problems, such as:
o Frequent urination
o	Leakage of urine (urinary incontinence).
o	kidney blockage following ureter blockage (rare).

 	Other symptoms, such as:
o	Difficulty or pain with bowel movements.
o	infertility. Sometimes, fibroids make it difficult to become pregnant.
o	Problems with pregnancy, such as placental abruption and premature labor.
o	miscarriage.
