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?

Fibroid tumour is the abnormal cell growth in the uterus and they are mostly benign. Fibroids usually affect women in the age bracket of 30 - 40. Fibroid tumours are of three types, depending on their location:

Submucosal fibroids: The tumour develops under the lining of the uterus
Intramural fibroids: The growth is found amongst the muscles in the wall of the uterus
Subserosal fibroids: The growth develops on the wall of the uterus right in the pelvic cavity
Causes behind it
The exact cause of fibroids in not known clearly. But certain factors have been discovered that might influence their formation. These factors include:

Hormones: Progesterone and estrogen are the hormones responsible for recreating the uterine lining during every menstrual cycle. These hormones might trigger the formation of tumour.
Family history: If any member in your family; your mother, grandmother or sister has/had fibroids in their uterus, you may also develop it.
Pregnancy: Your body produces excessive progesterone and estrogen when you are pregnant, which may cause an increase in the size of a pre-existing small fibroid. Myomectomy can be done by giving incision on the abdomen or by laparoscopy depending on the size and location of the fibroids.
Signs You are suffering from it

Heavy bleeding along with blood clots during or between your periods
Lower back or pelvic pain
Elevated menstrual cramping
Frequent urination
Pain during sex
Longer than normal periods
Bloating or pressure in lower abdomen
Enlargement or swelling of the abdomen
How it can be treated?
Your doctor will formulate the right treatment depending on your age, the mass of the fibroids and your overall health. Your doctor may choose a combination of treatment to cure your fibroids, and they include:

Medication: Gonadotropin releasing hormones (GnRH) agonists, birth control pills and ibuprofen (anti-inflammatory medicine) are prescribed. GnRH agonists reduce the level of progesterone and estrogen in your uterus.
Surgery: Myomectomy and hysterectomy are two common surgical procedures to treat fibroids. Myomectomy is performed by removing the fibroids only by making an incision on the abdomen. But hysterectomy completely removes the uterus. The latter is reserved for serious cases.
Non-invasive surgery: Forced ultrasound surgery, myolysis (shrinking fibroids with laser or electric current), cryomyolysis (fibroids are frozen) and endometrial ablation (an instrument uses heat, hot water, microwaves or electric current to destroy fibroids) are some non-invasive surgical procedures.

Breast Cancer - 6 Ways You Can Prevent It!

If you are concerned about liver cancer, you should know that most people do not experience signs and symptoms of the cancer in the early stages. Liver cancer is a form of cancer which occurs in the cells of the liver. There are various types of cancer which can develop in the liver. Hepatocellular carcinoma (HCC) is the most common liver cancer which begins in the hepatocyte, which is the main liver cell.

Symptoms-

Usually there are no specific primary stage symptoms of liver cancer. Some symptoms which may develop include the following:

Unusual weight loss is observed

Loss of appetite and developing food aversion

Pain in the upper abdomen

Nausea followed by vomiting

General weakness with intense fatigue

Swelling in the abdomen

The skin may become yellow

White and chalky stools are likely

Causes-

In most cases, the causes of liver cancer cannot be clearly determined. In some cases, the cause is known, such as chronic infection with the hepatitis virus, which may lead to liver cancer. Liver cancer occurs when the liver cells undergo changes or mutations in their DNA structure. DNA mutations lead to changes in instructions of chemical processes taking place in the body. The cells may grow out of control and develop into a cancerous tumour.

Risk Factors-

There are several factors which enhance the risk of liver cancer. They are as follows:

Chronic infection with hepatitis B or hepatitis C increases the risk of liver cancer.

A progressive and irreversible condition known as cirrhosis leads to scar tissue formation in the liver, increasing the risk of liver cancer.

Certain inherited liver diseases such as Wilson s disease and hemochromatosis also increase the chances of liver cancer.

People with diabetes are also at a greater risk of having liver cancer.

Non-alcoholic fatty liver disease (NAFLD), which is the accumulation of fat in the liver, also increases the chances of getting this condition.

Excessive alcohol consumption is another factor which causes irreversible damage to the liver and the chances of getting liver cancer get boosted.

Exposure to aflatoxins, which are poisons produced by molds growing on poorly stored crops, make you more likely to get liver cancer.

Several tests and procedures are carried out for the diagnosis of liver cancer. These include blood tests for diagnosing liver function problems, and imaging tests such as ultrasound, CT scan and MRI scan.

Top 4 Symptoms Of Liver Cancer

Rubbery cushions (discs) between the bones (vertebrae) stack up to form the spine. When a nerve between the disc and vertebrae is pressed and inflamed, that condition is called herniated disc. The herniated disc is also referred to as the ruptured disc or the slipped disc. This is caused when the soft jelly is pushed out due to a tear in the exterior. Herniated discs can lead to an irritation of the nerves and result in tremendous pain. It may also cause the arms and legs to become numb and weak. However, some people suffering from this condition may not display any symptoms at all.

Herniated disc generally occur in the lower part of the vertebral column. The herniated disc may also be seen in the thoracic spine or cervical spine. The symptoms of a herniated disc include pain in the legs, feet, or the buttocks, pain in the shoulder blade, tingling of the feet, numbness of the feet and hands, muscle weakness, neck pain or muscle spasm in the neck. Most common causes of herniated discs are aging, excessive weight or lifting of heavy weight.

Prevention of herniated disc

Herniated discs are very commonly found in people who are aged between 35 or 55 years. They are seen more commonly in the men in comparison to the women.
A herniated disc cannot be prevented easily, but there certain things that you can do to reduce the risks. Maintaining the proper techniques of lifting is important. You should not be bending at your waist. You should always bend the knees and keep the back straight. This helps you to use your leg muscles which are very strong to support the weight.
As the saying goes, precaution is better than cure, so here are few precautions that can be taken to avoid herniated discs. Practicing a proper posture can help in reducing the risk of a herniated disc. It is extremely important for an individual to maintain a healthy posture while standing, sitting, walking, and even sleeping. It is imperative that you stretch your muscles when you are sitting in one position for a long time.
Another important thing to avoid is high-heeled shoes, as they are few of the most common causes of a herniated disc. It would be a good idea to go for flat and well cushioned comfortable footwear as they can go a long way in reducing the risk of the herniated disc.
Exercising regularly can go a long way in keeping the muscles of the legs, stomach, and back very strong. You should try to balance your flexibility and strength by exercising regularly. The best form of exercise to avoid herniated disc or ruptured disc is aerobic exercise.
It is true that as you start to age, the chances of getting a herniated disc increase significantly. However, if proper precautions are taken, the stress put on the spine can be effectively reduced, thereby eliminating the risk of a herniated disc. 

Herniated Disc - Is There A Way It Can Be Prevented?

Breast cancer is one of the most common cancers in women about 1 in 8 women in the USA  develop invasive breast cancer. The incidence of breast cancer has increased with changes in lifestyle including smoking, drinking and loss of physical activity. The risk factors are age, ethnicity and family history cannot be changed. However, there are some risk factors that can definitely be acted upon to reduce the chances of developing breast cancer.

Weight management: Obesity is one of the major risk factors for breast cancer and managing weight and a good body mass index will help reduce the risk of developing breast cancer. This is especially important in women undergoing menopause.
Reducing smoking: The benefits of quitting it are manifold and reducing the risk for breast cancer is one of them. This will, as a byproduct, also result in a host of other benefits including improved quality of life, reduced chances of heart disease, stroke, and other cancers.
Physical activity: In addition to helping in weight management, this also helps reduce the risk of breast cancer. Ideal recommendation is 30 minutes of physical activity per day, plus strength training.
Breastfeeding: This helps in reducing the risk of breast cancer. Prolonged feeding is shown to have a greater protective benefit.
Hormone replacement therapy: When possible, limit the use of hormone replacement therapy for prolonged periods of time. Explore options of non-hormonal substitutes or use the least permissible or required dose. Be sure to get periodic check-ups when on hormone therapy.
Reduce exposure to environmental pollution: Higher levels of pollutants are linked to a higher incidence of breast cancer. When possible, avoid getting exposure to environmental pollutants.
Screening: If there is a strong family history or other risk factors, then screening can help detect breast cancer very early in the process. Recommended ages for mammography are as follows:
If you are age 40   44: Go for annual mammograms after discussing risks and benefits with the doctor.
If you are age 45   54: Go for annual mammogram.
If you are age 55 or over: Mammograms are recommended every other year. You can choose to continue to have them every year. Self-breast exams are not sufficient. However, if being done, they can also be an input to an abnormality.
Cautious use of birth control pills: Birth control pill usage to be discussed with your gynaecologist if you are above 35 years of age and smoke. The good news is that the risk associated with it disappears slowly after the pill is stopped.
These will help reduce the risk of developing breast cancer, early detection, and improved prognosis.
