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?

Many women develop uterine fibroids by the time they hit the age of 50 years and above. These are non-cancerous growths that may occur in the uterus. Most women go through severe bleeding and pain as well as discomfort as a result of these fibroids. Age, family history of the same condition, obesity or being overweight, eating habits and even ethnicity play a large role in deciding the risk of each individual patient. These fibroids can grow in the submucosal, intramural and subserosal areas.

Following are the common side effects of uterine fibroids:

    Frequent urination: Due to the pressure of the fibroids on the uterus, the patient may experience a constant feeling of fullness in the lower pelvic area of the body, which may lead to frequent filling of the bladder. This gives rise to frequent trips to the washroom for urination. 
    Heavy Bleeding: Severe bleeding is one of the most common causes of the presence of these kinds of fibroids. The patient may experience a lot of bleeding during menstrual periods, as well as pain and cramps the rest of the time. The periods will also be very painful when there are fibroids in the uterus or the uterine lining.
    Painful Intercourse: It is a well-known fact that any kind of infection or growth as well as sores and other such ailments can lead to vaginal dryness as well as pain during sexual intercourse. This is true for uterine fibroids as well, which can lead to severe pain during sexual activity. These fibroids can also give rise to pain in the lumbar or lower back region.
    Abdomen Swelling: The abdomen may go through significant swelling in such a condition and the patient may even look like she is pregnant. The growth can push the shape of the abdomen outwards and create a full feeling.
    Pregnancy Complications: The presence of uterine fibroids can give rise to several complications during pregnancy and even after child birth. One of the most common problems in this case is bleeding, followed by more severe outcomes like miscarriage. The women suffering from uterine fibroids are at greater risk of undergoing a caesarean section for the delivery of the baby. The baby may also be born breech and a premature delivery may take place. 
    Infertility: This is also a rare side effect of the uterine fibroids and is generally seen only in very severe cases. 
    Cancer: Only one in every 1000 cases might transform into malignant tumours. These uterine fibroids are generally known to be non-malignant. 

Any symptoms must be reported to a gynaecologist at the earliest to avoid any serious complications.

Common Side Effects of Uterine Fibroids

Uterine polyps are growths attached to the inner wall of the uterus that extend into the uterine cavity. Overgrowth of cells in the lining of the uterus (endometrium) leads to the formation of uterine polyps, also known as endometrial polyps. These polyps are usually noncancerous (benign), although some can be cancerous or can eventually turn into cancer (precancerous polyps).

Uterine polyps range in size from a few millimeters - no larger than a sesame seed - to several centimeters - golf-ball-size or larger. They attach to the uterine wall by a large base or a thin stalk.

You can have one or many uterine polyps. They usually stay contained within your uterus, but occasionally, they slip down through the opening of the uterus (cervix) into your vagina. Uterine polyps most commonly occur in women who are going through or have completed menopause, although younger women can get them, too.

Symptoms

Signs and symptoms of uterine polyps include:

Irregular menstrual bleeding - for example, having frequent, unpredictable periods of variable length and heaviness
Bleeding between menstrual periods
Excessively heavy menstrual periods
Vaginal bleeding after menopause
Infertility
Some women have only light bleeding or spotting; others are symptom-free.
When to see a doctor
Seek medical care if you have:

Vaginal bleeding after menopause
Bleeding between menstrual periods
Irregular menstrual bleeding
Causes

Hormonal factors appear to play a role. Uterine polyps are estrogen-sensitive, meaning they grow in response to circulating estrogen.

Risk factors

Risk factors for developing uterine polyps include:
Being perimenopausal or postmenopausal
Having high blood pressure (hypertension)
Being obese
Taking tamoxifen, a drug therapy for breast cancer
Complications

Uterine polyps might be associated with infertility. If you have uterine polyps and you're unable to have children, removal of the polyps might allow you to become pregnant, but the data are inconclusive.

Breast cancer is the form of cancer that occurs from breast tissues in women. Signs of breast cancer may include a lump in the breast, changes in the shape of the breast, dimpling of the breast skin, a fluid coming out of the nipples or development of red scaly patches on the skin. There might be pain in the bones, swollen lymph nodes, shortness of breath, or the skin turning yellow and pale.

Breast cancer is a fatal mode of cancer in women, and one must try to abstain from this cancer in all possible ways. Here are 5 ways you can decrease the risk of breast cancer.

1. Keeping a check on your weight: although the process is tough to maintain, keeping up a sound and healthy weight is a critical objective for everybody. Being overweight can expand the danger of a wide range of cancers, including breast cancer, particularly after menopause in women. Exercise is very important for maintaining a healthy body and lifestyle. Women who exert physically regularly are fitter than others and are at a much lower risk of acquiring diseases of any kind. Regular exercise decreases the chance of getting breast cancer and also keeps the body weight in check.

2. Maintaining a healthy diet: maintaining a healthy and balanced diet is a key for keeping away from any kind of cancer or major health problem. Include a sufficient amount of fresh fruits and green vegetables in your daily diet to ensure the supply of all vital nutrients to your body. This would increase your immunity.

3. Avoid smoking and consume less alcohol: smoking is a very unhealthy and harmful habit. Smoking lowers the quality of your life, and causes numerous diseases. Heart diseases, stroke and many kinds of cancer, including breast cancer can be caused from smoking. If you drink alcohol, you should moderate your drinking habits and drink less, as drinking in excess may lead to breast cancer.

4. Practice breast feeding: breast feeding your children for a span of one year or more is likely to reduce the risk of breast cancer.

5. Avoid taking birth control pills: birth control pills, in spite of having several benefits are associated with risk factors as well. Birth control pills have got worse effects in younger women than older aged women. Using birth control pills may cause breast cancer and these pills should be avoided.

There are many ways, adapting which you can lower the chances of getting breast cancer.

5 Easy Ways to Decrease Your Breast Cancer Risk

Brain injury can happen as a result of trauma, infection or degeneration with old age. Whatever be the reason, injury on the head can result into brain dysfunction and should be given required medical diagnosis. In these cases, occupational therapy can be a major help.

It helps in improving health, providing rehabilitation and educational service to enable people to participate in things they are interested in and manage their daily activities. Occupational therapy can be used to manage issues relating to memory, organization and attention span, behavior and emotion control, safety issues and issues which contribute to society. Depending on expectations, different therapies can be sought. Read on to know a little more about how occupational therapy can help adults with brain injury. 

The person's skills and what they want to do are to be assessed and accordingly a daily plan that can be easily followed is made. Where possible, use technology like smart phone or voice recorder to manage this plan. The therapist can train the person to use these tools, review progress and make changes as necessary.
The therapist will also teach ways to do things on their own like cooking and small shopping, so they become independent and are therefore less frustrated.
Patients in need of anger management, the therapist will help them to identify what induces anger or frustration and support in managing those before it turns into actual anger. This will help the person relax and be more positive.
This could also be done using small roleplays, wherein they are taught ways to respond and be more relaxed and calm.
If you are keen on participating in social events or volunteering opportunities, then the therapist can recommend options for you based on your areas of interest. The therapist can also work with the identified organization (school, NGO, or workplace) to inform them of the kind of support required by you. Work behavior and social behavior can be taught to help the affected person succeed.
If the affected person happens to be alone, then they need to be assessed for ability to judge (e.g., self-awareness, impulsivity, and reliability), even while doing daily activities like bathing and dressing. Driving is permissible only if cleared for it by the therapist.
The home needs to be assessed for safety. You may have to make some safety modifications, for instance replace power tools with hand tools. Else, shared housing options, where independence and having someone close by is possible, should be evaluated.
So, with a brain injury, not all is lost. Occupational Therapy can definitely help restore function to a large extent, so use it to reap maximum benefits.

Cancer is the abnormal, uncontrolled growth of cells in a particular body part. With continued growth, pieces of this tissue travel through the blood to different body parts and continue to grow in the new area. This is known as metastases. Breast cancer is one of the most common forms of cancer and affects about 1 in 8 women in the USA. Read on to know more details of breast cancer   breast anatomy, causes, symptoms, risk factors, detection, prevention, and of course treatment.

Anatomy: The main function of the breast is lactation through its milk-producing tissue that are connected to the nipple by narrow ducts. In addition, there is surrounding connective tissue, fibrous material, fat, nerves, blood vessels and lymphatic channels which complete the structure. This is essential to know as most breast cancers develop as small calcifications (hardened particles) in the ducts or as small lumps in the breast tissue which then continues to grow into cancer. The spread can happen through lymphatic or blood flow to other organs.

Warning signs/symptoms: The following are some symptoms that need to be watched out for if you have a predisposition to breast cancer.

    A lump in either of the breasts or armpits
    Change in size, shape, or contour of either breast
    Redness of your breast or nipple
    Discharge of clear or bloody fluid
    Thickening of breast tissue or skin that lasts through a period
    Altered look or feel of the skin on the breast or the nipple (dimpled, inflamed, scaly, or puckered)
    One area on the breast that looks very different from the other areas
    Hardened area under the breast skin

Either one or a combination of these should be an indication to get a detailed checkup done. Early diagnosis results in controlling the disease with minimal treatment and reduced complications.

Causes and risk factors: The exact cause for breast cancer is yet to be pinned down. However, risk factors are clearly identified, and women with risk factors need to watch out for warning signs.

    Family history: Of all the risk factors, the family history is the most important. Breast cancer runs in families, and if there is a first-degree relative with the breast cancer, the chances of developing it are almost double. Two genes BRCA1 and BRCA2 are the carriers of the disease, and this testing can be done in women to identify if they are at risk.
    Family history of other cancers: Even if there is no breast cancer, if there are other cancers that run in the family, watch out.
    Age: Women over 50 are at higher risk of developing breast cancer.
    Race: Caucasian and Jewish women are at higher risk of breast cancer than African-American women.
    Hormones: Greater exposure to the female hormone estrogen increases the chances of developing breast cancer. Women who use birth control pills for contraception and hormone replacement after menopause are at a higher risk of developing breast cancer.
    Gynecologic milestones: Women who have abnormal menstrual milestones need to watch out. These include those who attain menarche before 12 years of age, get pregnant after 30, attain menopause after 55, and have menstrual cycles shorter than 26 days or longer than 29 days.
    Obesity and alcohol abuse are also likely to increase a woman s chances of developing breast cancer.

Stages: Starting from stage 0, higher stages indicate advanced disease.

    Stage 0: The growth which has begun in the milk-producing tissue or the ducts has remained there (in situ) and not spread to any other area, including the rest of the breast.
    Stage I: The tissue slowly becomes invasive and has begun to affect the surrounding healthy tissue. It could have spread to the fatty breast tissue and some breast tissue may be found in the nearby lymph nodes.
    Stage II: The cancer at this stage grows considerably or spreads to other parts. There are chances that cancer may grow and also spread.
    Stage III: It may have spread to the bones or other organs but small amounts are present in up to 9 to 10 of the lymph nodes in the armpits and collar bones which makes it is difficult to fight.
    Stage IV: The cancer is widespread to far-flung areas like the liver, lungs, bones, and even the brain.

Screening: This is one of the most effective ways to identify the disease in its early stages. This will help in controlling cancer from spreading with minimal treatment.

    Self-examination: A thorough self-examination to look for changes in terms of shape, size, colour, contour, and firmness should be learned by all women. Watch for any discharge, sores, rashes, or swelling in the breasts, surrounding skin, and nipple. Examine them while standing and when lying down.
    In most women, annual screening mammograms are advised after the age of 40. However, in women who have a strong family history or genetic makeup, it is advisable to have screening mammograms starting at age 20 every 3 years and then annually from the age of 40.
    Women in high-risk categories should have screening mammograms every year and typically start at an earlier age.
    Ultrasound screening can also be given in addition to mammograms.
    Breast MRI is another way to screen for breast cancer if the risk is greater.

Breast Cancer Prevention: Now that there is so much awareness about causes and risk factors, there are definitely ways to prevent or delay the onset of the disease.

    Exercise and a healthy diet with reduced amount of alcohol are definitely effective in minimising the chances of developing cancer.
    Tamoxifen is used in women who are at high risk for breast cancer.
    Evista (raloxifene) which is used to treat osteoporosis after menopause. It is also widely used in preventing breast cancer.
    In high-risk women, breasts are surgically removed to prevent the development of cancer (preventive mastectomy).

Treatment: As with all cancers, treatment would depend on the stage at which it is identified and include a combination of chemotherapy, radiation, and surgery. As noted earlier, if you are at risk, look out for warning signs as early diagnosis is the key to maximum recovery.
