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.

Breast Cancer - 8 Things You Must Do To Avoid it!

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?

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 begins when cells in the breast(s) start to grow out of control. It is understood as being the most common cancer, seen predominantly in females, globally. It is reasonably treatable and often curable.

1. Type: Adenocarcinomas constitute more than 95% of breast cancers with infiltrating ductal carcinoma (IDC) being the most common form of invasive breast cancer.

Frequently occurring breast cancers present as one of the following types mainly

1. Ductal Carcinoma In Situ (DCIS): Is the most common type of non-invasive breast cancer and is confined to the milk ducts of the breast. There is no invasion in the basement membrane. Pure DCIS metastasizes rarely. Non comedo cribrioform carcinoma is the most common DCIS found which, when compared to the comedo type, is mostly non-aggressive.

2. Infiltrating Ductal Carcinoma (IDC): Represents majority (about 3/4th) of the breast cancers, and is known to metastasize commonly to bones, lungs and liver.

3. Lobular Carcinoma In Situ (LCIS): Develops in multiple lobules of the breast (bilaterally). LCIS is less commonly seen, compared to DCIS.

4. Infiltrating Lobular Carcinoma (ILC): Represent about a tenth of all breast cancers and tends to metastasize to other regions of the body.

Less commonly occurring breast cancers such as

5. Inflammatory Breast Cancer: Is relatively uncommon and are caused probably owing to viral infections. The breast is warm, red and swollen.

6. Paget s disease of the nipple: Is a rare form of breast cancer. It begins in the milk ducts and spreads to the nipple and areola.

7. Medullary Carcinoma

8. Mutinous Carcinoma

9. Tubular Carcinoma

10. Phylloides tumor etc all.

2. Gender: Affects the female populace predominantly. However, a small percentage of breast cancer is attributable to the male populace as well.

3. Etiology: No definite cause is known. However, diet, lifestyle, environment, hormonal/ reproductive factors, personal or family history of breast cancer especially in first degree relatives and also any benign breast disease history etc all are known to increase the risk of breast cancers. Specifically, excessive fatty diet, obesity, type 2 diabetes mellitus, benign breast disease, heredity/ inheritance of mutated breast cancer genes 1 (BRCA1) and 2 (BRCA2), smoking, alcohol intake, infertility, estrogen therapy/ hormone replacement therapy (long term) in post menopausal women, delayed age at first pregnancy, nulliparity (not having child), early menstruation, delayed onset of menopause, lactating mothers not breast feeding, exposure to ionizing radiation, sedentary lifestyle, depression, exposure to MMTV virus etc all can potentially increase the risk for breast cancer.

4. Features: Signs & symptoms, of breast cancer, manifest majorly in the following ways

Lump/ nodule in the breast that gets attached to the skin of the breast over time. The lump / nodule could be hard and painless with irregular edges or it could also be soft, rounded, tender and painful.

Enlarged lymph nodes in the axilla which are palpable.

Swelling of whole or a part of a breast. This is even if there is no distinct lump felt.

Retraction or thickening of the nipple(s).

Pain in the breast or nipple.

Discharge from nipple other than breast milk.

Irritation/ scaliness of skin over the breast.

Redness of nipples

Rarely, red, swollen and tender breast.

5. Screening: Is generally recommended for asymptomatic populations goal of which, as usual, is to be able to detect & diagnose breast cancer at an early stage which is potentially curable. It is mostly radiologic with mammography/ USG being instrumental in raising suspicions for further diagnostics (i.e. biopsy) that help detect breast cancer, if any, early.

6. Diagnosis: A self-examination/ clinical exam of the breast(s)/ axilla that reveals a palpable mass prompts the following diagnostics. Abnormal blood test results may be indicative of malignancy, but a follow up imaging/ biopsy is always the gold standard for accurate diagnosis.

Blood: ER/ PR/ HER2/neu, uPA, PAI-1, CA15-3, CA27.29 etc all tumor markers are helpful.
Imaging: Mammography/ USG Scan usually, as relevant. Again, CT Scan of abdomen & pelvis and chest, PET CT scan, bone scan etc all help detect metastasis, if any, for cancers in stage III & above.
Biopsy: either excisional, incisional, fine needle aspiration (FNA) or core biopsy technique, as contextually appropriate, is frequently employed and a histopathological examination (HPE) thereof clinches the diagnosis and the nature of the disease.
7. Treatment: Conventional treatment includes surgery, radiotherapy, hormone therapy/ chemotherapy as deems appropriate. Simultaneously, an adjunctive or integrative naturopathic treatment with suitable complementary & alternative medicines (CAM) too can help improve clinical outcomes and facilitate recovery as would be feasible contextually.

8. Prognosis: Preventive measures, earlier diagnosis and right early treatment is key for an effective therapeutic management & better prognosis. Like most other cancers, the chances of cure for an early stage breast cancer are more. The cure/ recovery chances are influenced by the type, grade, stage of cancer, recurrence and the patient s general health & vitality etc all. Above-mentioned apart, age, menopause status, lymph node status, ER/ PR/ HER-2/ neu status, size & extent of breast cancer etc all also influence the treatment outlook in breast cancer. The five year survival rate is strongly correlated with the stage of breast cancer.

9. Prevention: Rightly said, prevention is always a better choice. Although genetic risks are difficult to modify, still an increased focus on protective factors and avoidance of the risk factors can be of help. An adherence to a Mediterranean diet, maintaining an ideal body weight and an active lifestyle with due emphasis on regular exercising (for at least 30 minutes daily), de-stressing and relaxation is highly recommended for reducing the risks of breast cancer. A healthy eating plate comprises essentially a low fat diet, fibre rich foods including whole grain cereals, green leafy vegetables cooked using healthy vegetable oils, fresh fruits of all colours as seasonally available and healthy proteins/ fats including fresh fish, poultry, beans, nuts etc all. It is advisable to limit milk/ dairy, preferably of low fat content, to 1 to 2 servings max daily. Although alcohol is optional and is not for everyone, the consumption of the same, if any, has to be strictly in moderation, and is best avoided. Smoking is to be avoided as well. Again, red meat, butter, refined grains, sweets, sugary drinks including carbonated beverages and other high calorie foods etc all, if any, are to be taken sparingly or are best avoided too. Limiting dosage/ duration of hormone therapy, if any, especially to counteract post menopausal symptoms and also avoiding exposure to radiation and environmental pollution can help reduce the risks of breast cancer. Apart from the above-mentioned, for high risk cases, a prophylactic oophorectomy, prophylactic radical mastectomy, long term hormone therapy etc all can help reduce the chances/ risks of developing breast cancer significantly. Breastfeeding is known to confer protection against breast cancer risk too.

Breast Cancer - In A Nutshell

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!

Cancer of the kidneys is amongst the ten most common types of Cancer. There are many types of renal cancer with Renal cell carcinoma being the most common amongst them. Renal cancer is said to be triggered by a genetic mutation but the cause for this mutation is yet unknown. While kidney cancer appears suddenly in some cases, in others it is inherited from the parents. Here are 4 things you should know about cancer of the kidneys.

Risk Factors
Along with a mutation of the genes which is beyond our control, some lifestyle factors can also increase a person s risk of suffering from renal cancer. Some of these factors are:

Smoking
Obesity
High blood pressure
Symptoms
An early diagnosis can make the treatment of renal cancer much easier than if it is left undiagnosed. Hence, it becomes important to recognise the symptoms of this disease. Common renal cancer symptoms include:

Blood in the urine
A lump on either side of the abdomen
Persistent pain on one side of the abdomen
Tiredness
Unexplained weight loss
Fever
These symptoms are common to a number of other diseases as well and hence if you experience them, it is best to get yourself checked out by a doctor. In order to confirm a diagnosis, your doctor is likely to ask for blood tests, urine tests, an ultrasound and a CT scan or an MRI. In most cases, your doctor will also schedule a biopsy to check for cancer cells in the kidney tissue.

Stages of kidney cancer
Once cancer has been diagnosed, your doctor will need to determine the extent of damage caused in order to find the best form of treatment for the disease. Stages of kidney cancer are determined by the size of the tumour and on how much it has spread from the original location. There are four stages of kidney cancer.
Stage I   When the cancer cells are restricted to the kidneys and the tumour is no bigger than 3  in diameter
Stage II   The tumour has grown bigger in size but is still restricted to the kidney
Stage III   The tumour may be big or small but has spread to at least one lymph node or has affected the blood vessels
Stage IV   The cancerous cells have spread to nearby lymph nodes or other organs or the tumour has grown through the fatty layer and outer fibrous layer of the kidney.

Treatment
Kidney cancer can be cured easily if detected in the early stages by removing the tumour and adjacent tissue or the entire kidney if need be. Removing one kidney is not fatal as a person can live a healthy life with a single kidney.
