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?

Breast cancer begins when cells in the breast start to get out of control. These cells are mostly in the form of a tumor that can be regularly seen on an x-ray or felt as a lump. The tumor is dangerous (malignant) if the cells attack the surrounding tissues or spread to far off zones in the body. Breast cancer happens mostly in women, yet men can get it, as well.

This is how breast cancer can spread:

Bosom cancer can spread through the lymph framework
The lymph framework includes lymph nodes, lymph vessels, and lymph liquid found all throughout the body
Lymph nodes are little, bean-shaped accumulations of immune system cells that are connected by lymph (or lymphatic) vessels. Lymph vessels resemble little veins, with the exception of that they transport a liquid called lymph (rather than blood) far from the breast
Lymph contains tissue liquid, waste items, and immune system cells. Breast cancer cells can enter lymph vessels and start to develop into lymph nodes
A large portion of the lymph vessels of the breast deplete into the:

Lymph nodes under the arm (axillary hubs)
Lymph nodes around the neck bone (supraclavicular and infraclavicular lymph hubs)
Lymph nodes inside the neck close to the breast bone (inner mammary lymph hubs)
Following are some of the causes of breast cancer:

Hormones play a part in creating breast cancer disease; however exactly how this happens is not completely known
Ordinary breast cells get to be distinctly carcinogenic in view of changes (transformations) in DNA
Yet, most DNA changes identified with breast cancer are gained in breast cells during a woman s life as opposed to having been acquired
Qualities that accelerate cell division are called oncogenes
Tumor silencer qualities are typical qualities that back off cell division, repair DNA oversights, or advise cells when to bite the dust
Certain acquired DNA transformations (changes) can drastically increase chances for building up specific growths and are in charge of a large number of tumors that keep running in few families
Some of the treatments of breast cancer include:

Health alterations: Body weight, physical action, and eating routine are all connected to breast tumor, so these may be territories where you can make a move.
Restorative alternatives for women at expanded hazard: For women who have certain hazard components for breast growth, for example, a family history; various restorative alternatives may counteract breast cancer.
Medications to lessen hazard: For women at expanded danger of breast cancer, medications, for example, tamoxifen and raloxifene, can reduce the hazard. However, these medications can have their own dangers and symptoms.
Preventive surgery: In case that you have a solid family history of breast cancer, you can talk with your specialist about hereditary testing. This test addresses changes in qualities that increase the danger of breast cancer; for example, the BRCA qualities. In case you have a hereditary change from a family with a transformation, however, have not been tried, you could consider surgery to bring down your danger of tumor.

Breast Cancer - Important Things You Must Be Aware Of!

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.

Breast Cancer - Know More to Say 'No' More!

Uterine cancer is also known as endometrial cancer. It is a cancer which begins in the lining of the uterus. The uterus is the part of a woman's body where the fetus develops. Uterine cancer is one of those rare cancers in India, which can be diagnosed in its early stages. This is because excessive vaginal bleeding occurs, thus making it a very serious and an apparent symptom. It is also one of the few forms of cancer which can be cured as removing the uterus is often more than enough to cure the patient of uterine cancer.

Here are the causes, diagnosis and treatment of uterine cancer:

Causes

The exact cause of uterine cancer is not yet known, however, there is a theory on what causes uterine cancer. Hormones in a woman's body have been thought to increase the chances of getting uterine cancer. This is because it has long been thought that having high levels of estrogen is the cause of uterine cancer. Increased estrogen thickens the endometrium and thus, increases the likelihood of uterine cancer.

Diagnosis

There are several tests used to diagnose whether you have uterine cancer including:

1. Pelvic exam: This is an examination in which the vagina, bladder, rectum and uterus are scanned for lumps. If they are found, it might be due to uterine cancer.
2. Pap test: A pap test is a special test designed to scan for uterine cancer.
3. Transvaginal ultrasound: A transvaginal ultrasound uses high-intensity sound waves so that pictures of the uterus can be taken.
4. Biopsy: During a biopsy, the doctor will remove tissue from the endometrium and it will then be analyzed for cancerous growths.

Treatment

1. Surgery: This is the most common treatment as it removes the entire uterus and prevents the spreading of the cancer.
2. Chemotherapy: Chemotherapy involves giving drugs which kill cancerous cells. They are given through either an intravenous line or even in pill form.
3. Hormone therapy: This is a therapy in which either progesterone levels are increased or estrogen levels are decreased.
4. Radiation therapy: In this treatment, high energy laser beams are used to destroy cancerous cells.

Uterine Cancer - Causes, Diagnosis and Treatment

Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast. It occurs in both women and men, although breast cancer in men is rare.

Risk factors:

Lack of physical activity
Alcohol consumption
Advancing age
No childbirth or no breastfeeding
Family history of breast cancer
Early menarche (< 12 years of age) or late menopause ( > 55 years of age)
History of ovarian cancer or endometrial cancer
History of benign breast conditions (e.g. atypical hyperplasia) or lobular carcinoma in situ
Receiving hormonal replacement therapy (HRT)
History of receiving radiation therapy to the chest before age of 30
More importantly, you can lower your risk of having breast cancer by the following measures:

 Have regular physical activities, do at least 150 minutes of moderate-intensity aerobic physical activities per week (e.g. climbing stairs or brisk walking)
Avoid alcohol drinking;
Maintain a healthy body weight and waist circumference - aim for a body mass index (BMI) between 18.5 and 22.9, and a waist circumference of not more than 80cm for women; and
Have childbirth at an earlier age and breastfeed each child for longer duration factors include:
What are the common symptoms of breast cancer?

The symptoms of breast cancer may not be easily noticed at an early stage. Any of the following changes in the breast can be a symptom of breast cancer:

  Breast lump;

  A change in the size or shape of the breast;

  A change in skin texture of the breast or nipple (e.g. red, scaly, thickened or  orange-skin  appearance);

  Rash around the nipple;

  In-drawing of the nipple;

  Discharge from one or both nipples;

  New and persistent discomfort or pain in the breast or armpit; and

  A new lump or thickening in the armpit

What is breast cancer screening? Should I screen for breast cancer if I do not have any symptom?

Screening means examining people without symptoms in order to detect disease or fi nd people at increased risk of disease. It is often the fi rst step in making a defi nitive diagnosis. For breast cancer screening, its purpose is to fi nd women who have breast cancer, before they have any symptom, in order to offer them earlier treatment.

Mammography is widely used as a screening tool. It is an X-ray examination of the breasts. During mammography, the breast is pressed between 2 plates to flatten and spread the breast tissue, in order to obtain a clear image. Some women may find it uncomfortable or painful but the discomfort is usually short lasting. Mammography screening is safe in general and only a very small dose of radiation is used in the procedure. One in 5 female breast cancer patients may be missed by mammography.

Prevention and Screening for Breast Cancer: Information for women and their families

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.
