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?

The presence of a lump or a tumor in the breast is not always indicative of breast cancer. In some instances, the breast tumor can be benign or noncancerous as well. Thus, to understand breast cancer better, one should know the difference between a benign and malignant breast tumor. In this article, we will discuss the factors that differentiate a benign breast tumor from a malignant one.

Breast Fibroadenomas

Breast Fibroadenomas are benign breast tumors that often affect women in their early 20s and 30s (can also affect women of other age groups). Research suggests that in spite of being benign and noncancerous, breast fibroadenomas make a woman more susceptible to breast cancer in the future.
It may be difficult to decipher the underlying factor that triggers fibroadenomas. However, increased use of birth control pills (that results in an elevated estrogen level) can be a contributing factor.
Thus, in spite of no discomfort, it is safe to get fibroadenomas removed by lumpectomy or by radiation therapy. There are also instances when fibroadenomas dissolved on their own.
Sometimes, the lobules of the breast can undergo enlargement resulting in the formation of lumps (can be a tumor or a cyst) that are non-cancerous in nature. Such tumors are known as Adenosis.
The benign tumor growth can also develop in the milk ducts of the nipples, a condition known as  Intraductal papillomas (characterized by discharge from the nipples).
To stay safe and lower the risk of breast cancer, doctors often recommend the removal of the tumor.
Differences between Benign and Malignant Breast Tumors

One of the major factors resulting in a tumor is the abnormal growth of cells that could be triggered by an injury, an infection or prolonged inflammation.
A factor that plays a pivotal role in differentiating malignant from benign breast lumps or tumors is its ability to metastasize or invade other organs, cells and tissues of the body.
A malignant tumor starts off as a primary tumor that remains confined within its point of origin. Gradually, the cancerous growth metastasize, invading other neighboring as well as distant cells and body organs (Secondary cancer or tumor).
Benign tumors, on the other hand, contains chemical adhesions that prevent their metastasis and invasion to the other vital organs in the body.
As compared to malignant tumors, benign breast tumors, once removed, do not recur.
On the cellular level, microscopic examination reveals that malignant breast tumors often contain unusual, mutated, and modified genes and chromosomes.
More than often, malignant breast tumors give rise to Paraneoplastic Syndrome. The Paraneoplastic Syndrome is characterized by an elevated production of substances (can be antibodies or hormones) by the cancerous growths or tumors. The hormones or the antibodies circulate in the bloodstream and can alter the functioning of a host of vital body tissues and organs with deleterious health consequences.
Such things seldom take place in the case of benign breast tumors.

Benign & Malignant Breast Tumors - Things You Must Be Aware Of!

Breast reduction or breast reduction surgery is a form of cosmetic surgery where the size of disproportionately large breasts is reduced.

Extra large breasts may cause neck pain, back pain and several other physical symptoms. Many women undergo a breast reduction to make life easier. This surgery provides effective results.

The procedure of breast reduction surgery-

Breast reduction surgeries can be conducted in an outpatient facility. You may have to stay for one night at a hospital as well. While performing this surgery, a patient is given general anaesthesia, which will make the patient asleep during the process.

Breast reduction surgery requires about two to five hours to be completed successfully. During the process, the surgeon will create a cut around the nipple and then on the breast. The cut is made in the shape of a keyhole. Extra skin, tissue and fat will be removed from the breast through the keyhole-shaped incision. Drainage tubes are also utilized for removal of excess skin and fat. After the removal is complete, and enough skin has been removed, the breasts are stitched. They are then wrapped in a special gauze. Sometimes, a surgical bra is required to be worn by the patient during the surgery.

Recovery from breast reduction surgery-

After a breast reduction surgery is performed, the patient must take a minimal one week off from any kind of work or school. Some women require two weeks or more to recover. However, this varies from patient to patient, but not more than three weeks are required for recovery.

You will be having a follow-up appointments with your surgeon, where the bandages and stitches on the breasts are removed.

As a part of the recovery process, a woman must abstain from all kinds of physical activities for one month following the surgery. After the surgery, it is likely for a patient to feel tired and experience breast pain. However, this is normal and you can have oral pain killers prescribed by your surgeon to get relief and ease. Heavy lifting should be strictly restricted.

Breast reduction surgery is an efficient cosmetic surgery, which enables women to reduce their breast size and volume. The results of such a surgery are quite satisfactory.

Breast Reduction - Know The Procedure and Recovery!

We have more than 200 bones in our body and each of them is susceptible to bone cancer. However, long bones in the arms and legs are most susceptible to this condition. Bone cancer can be primary or secondary. Primary bone cancer involves uncontrolled and abnormal cell division within the bones while secondary bone cancer refers to cancer that originated somewhere else in the body and later spread to the bones. While children and adults are equally at risk for primary bone cancer, adults and elderly people are more susceptible to secondary bone cancer. If diagnosed early enough, bone cancer can be treated and even cured with surgery, chemotherapy or radiation. 

Hence it is essential to recognize the signs and symptoms of bone cancer. Here s what you should look out for.

Pain in Bones: Pain is one the primary symptoms of bone cancer. As the tumour grows larger, this pain can become more intense. In its early stages, the pain may be experienced as a dull ache inside the bone or the affected part of the body. It may also increase or decrease according to your activity level or may be experienced only at night. However, not all bone pains signify  cancer  as this is also a symptom associated with osteoporosis.
Swelling: In some cases, the abnormal growth of bone cells can result in the formation of a lump of mass that may be felt through the skin. In other cases, the affected area may also show signs of swelling.
Breaking of the Bone: Cancer can weaken the bones and make them more brittle. This may make the bones more susceptible to fractures. A bone breaking in an area that has been painful or sore for a long period of time may be a sign of cancer. This is known as a pathologic fracture.
Reduced Flexibility: If the tumour is located near a joint, it may affect the range of movements possible and make simple actions uncomfortable. For example, a tumour around the knee may make walking and climbing stairs a painful exercise.
Other symptoms to look out for are sudden and drastic weight loss, tiredness, excessive sweating at night, fever and difficulty breathing in case cancer has spread to other organs. Since many of these symptoms are common to other medical disorders, you should conduct a doctor immediately if you notice any of them. A physical examination and a couple of tests along with a biopsy will be required to confirm a diagnosis of bone cancer.

Bone Cancer - 4 Signs You are Suffering from it!

A broken bone or a fracture can be painful and it requires medical attention for the fracture to heal properly. Proper healing is necessary for the right alignment of the bone. A doctor chooses to either reduce or set the bone in terms of new alignment. The bone reduction can happen manually or surgically depending on the severity of the injury. A Surgical procedure known as the open reduction internal fixation is performed for serious fractures. It ensures that the all the broken pieces are fixed together and the injury can heal properly.
Post the fracture, the bone need to be immobilised for proper healing. This is generally achieved by imposing a cast. For fractures that are not severe in nature, a doctor might choose to impose a temporary cast so that simple motion can happen around the site of the injury. For serious fractures, a permanent cast is placed around the injury site. In the case of a shoulder injury, a patient is required to wear a sling so that the bones are immobilised.


Time Duration of a Therapy Session:
While the exact duration of physiotherapy can vary from individual to individual, it takes a minimum of 2-8 weeks for the fracture to completely heal. Certain fractures take more time to heal. The rate of healing also depends on the severity of the injury, pain threshold level of the patient, extent of work with the physiotherapist, the robustness of the physiotherapy program, extent of the injury of the soft tissue and certain other factors. Typically shoulder and neck injuries heal quicker than a fracture of the legs. The time duration of fracture healing also depends on the type of bone that has been affected.


Physiotherapy in a Hospital:
If the fracture happens in the ankle or leg, a physiotherapist might have to intervene in the hospital in order to teach patient about using assistive devices such as crutches and cane. Things that are taught during this time include using the device in order to climb stairs, right walking posture, getting into a car, taking the device off while sitting and such other techniques.


Physiotherapy at Home:
Physiotherapy can also happen from home if the doctor specifically instructs to do the same. This is typically done for people where the condition is too serious to go outside and get the physiotherapy done. Certain weight bearing restrictions are imposed around this time. The training remains the same as in the case with a hospital.


In the Clinic:
Once the patient becomes mobile enough, a doctor might suggest a patient go to a clinic to get the physiotherapy done. A physiotherapist evaluates certain things such as pain, range of motion, gait, flexibility etc. of the patient before suggesting a certain exercise plan. 




How Long Do You Need Physiotherapy Post-Fractures?

Breast cancer begins when the cells that are present in the breast start to go out of control. These cells generally form a tumor which can be seen on mammogram or one can feel it as a lump. The tumor is threatening if the cells can grow into the tissues that surround it or spread to other areas of the body. Breast cancer happens mostly in ladies. Here are a few methods with which you can prevent breast cancer-

Keep your weight in check: Maintaining a healthy weight is important for everyone although, it is easy to tune it out since it is said so often. Being overweight can expand the danger of a wide range of cancers, including breast cancer, particularly after menopause.

Eat Your Fruits and Vegetables and Avoid Too Much Alcohol: A balanced and healthy diet can bring down the danger of breast cancer. Attempt to eat a considerable measure of fruits and vegetables and keep liquor at moderate levels or lower. While moderate drinking can be useful for the heart in most grown-ups, even low levels of intake can build the danger of breast cancer. If you do not drink, don't feel you have to begin. In case you drink modestly, there is less risk.
Try not to Smoke: Smokers and non-smokers alike know how undesirable smoking is. It brings down a person s quality of life and expands the danger of heart and lung diseases, stroke, and no less than 15 types of cancer, including breast cancer. It additionally causes bad breath, awful teeth, and wrinkles.
Breastfeed, If Possible: Breastfeeding for almost one year or more brings down the danger of breast cancer. It additionally has extraordinary medical advantages for the baby as well, especially in terms of immunity.
Keep away from Birth Control Pills: Contraceptive pills have both dangers and advantages. In many cases, the more young a lady is, the lower the danger is. While ladies are taking birth control pills, they have more chances of falling prey to breast cancer as per various medical studies. This danger leaves rapidly in the wake of stopping the pill. The danger of stroke and heart attack is increased while on the pill, especially if the woman smokes. Long term use can likewise have essential advantages, such as bringing down the danger of ovarian cancer, colon tumor and uterine cancer and undesirable pregnancy. In case you are exceptionally worried about breast cancer, staying away from birth control pills is also an alternative to lower the risk.
