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

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 symptoms caused due to herniated disc can be very severe and can also cause a bit of disability. The disc of the spine is like a cushion and separates the set of bones on the backside. The discs are shock absorbers of the spine and are mainly composed of 2 parts, a soft jelly centre called the nucleus and a tough outer covering called the annulus.

Effects of Herniated Disk
A herniated or cracked disc is a severe condition and it seems to happen most commonly in the lower back.  It happens when a fraction of the soft centre gets pushed through the destabilized area due to degeneration, trauma or by putting pressure on the spinal cord. 

Nerves are located precisely at the back of every disc and are responsible for controlling everything in our body. While a disc gets herniated, the external covering of the disc tears and creates a bulge. The soft jelly gets shifted from the centre of the disk to the region where the damage has occurred on the disc. Most commonly, the bulge occurs in areas where the nerve is located and it causes strain on the affected nerve. It has been observed that individuals do not feel any painful sensations even if their disc gets damaged.

When is Surgery Recommended for Herniated Disc?
Surgery for herniated disc is recommended only after options like steroid injections, pain relievers, exercise and non-steroid anti-inflammatory drugs do not work. If the pain persists even after these options, then it becomes important to go for surgery. There are certain risks involved in this surgery like infection, bleeding or nerve damage. 

There are chances that the disc may get ruptured again if it is not removed. If you are a patient suffering from degenerative disc disease, then there are chances that problem occurs in other discs. It is very important that a patient maintains healthy weight to prevent any further complications.

The main factor that increases the risk of herniated disc is excess body weight, which causes a lot of stress on the lower back. A few people become heir to a tendency of developing this condition. Even individuals with physically demanding jobs are prone to this condition. 

Activities like bending sideways, pushing, twisting, repetitive lifting can increase the risk of a herniated disk. At times, emergency surgery is also required to avoid paralysis in a patient.

Herniated Disc - What are the Risks Involved in it?

Definition

Uterine fibroids are noncancerous growths of the uterus that often appear during childbearing years. Also called leiomyomas (lie-o-my-O-muhs) or myomas, uterine fibroids aren't associated with an increased risk of uterine cancer and almost never develop into cancer.

Uterine fibroids develop from the smooth muscular tissue of the uterus (myometrium). A single cell divides repeatedly, eventually creating a firm, rubbery mass distinct from nearby tissue. Fibroid location, size and number influence signs and symptoms:

TYPES

 	Submucosal fibroids: Fibroids that grow into the inner cavity of the uterus (submucosal fibroids) are more likely to cause prolonged, heavy menstrual bleeding and are sometimes a problem for women attempting pregnancy.
 	Subserosal fibroids: Fibroids that project to the outside of the uterus (subserosal fibroids) can sometimes press on your bladder, causing you to experience urinary symptoms. If fibroids bulge from the back of your uterus, they occasionally can press either on your rectum, causing a pressure sensation, or on your spinal nerves, causing backache.
 	Intramural fibroids: Some fibroids grow within the muscular uterine wall (intramural fibroids). If large enough, they can distort the shape of the uterus and cause prolonged, heavy periods, as well as pain and pressure.

Symptoms

In women who have symptoms, the most common symptoms of uterine fibroids include:

 	Heavy menstrual bleeding
 	Prolonged menstrual periods - seven days or more of menstrual bleeding
 	Pelvic pressure or pain
 	Frequent urination
 	Difficulty emptying your bladder
 	Constipation
 	Backache or leg pains

 	Abnormal menstrual bleeding, such as:
o	Heavier, prolonged periods that can cause anemia
o	Painful periods.
o	Spotting before or after periods.
o	Bleeding between periods.

 	Pelvic pain and pressure, such as:
o	Pain in the,abdomen pelvis, or low back.
o	Pain during sexual intercourse.
o	bloating and feelings of abdominal pressure.

 	Urinary problems, such as:
o Frequent urination
o	Leakage of urine (urinary incontinence).
o	kidney blockage following ureter blockage (rare).

 	Other symptoms, such as:
o	Difficulty or pain with bowel movements.
o	infertility. Sometimes, fibroids make it difficult to become pregnant.
o	Problems with pregnancy, such as placental abruption and premature labor.
o	miscarriage.

Tests and diagnosis

Ultrasound
Magnetic resonance imaging
Hysterosonography
Hysterosalpingography
Hysteroscopy

Uterine Fibroids - All You Should Know!

Uterine fibroids are referred to as benign, abnormal growths which tend to develop in the uterine walls of a woman. The size of such growths can range from a few centimeters to even excess of a few inches. As such, they can cause the uterus to increase to the size of a five month pregnancy. Although, the symptoms of fibroids are not always apparent, they often cause heavy bleeding and pain in women. A recent research concluded that around 60 to 75 percent women contract such fibroids by the age of 50, at least once in their life.

Depending on the site of formation, uterine fibroids are distinguished into different types. Intramural fibroids in the lining of the uterus and subserosal fibroids which develop outside the uterus are the most commonly observed fibroids.

What causes Uterine Fibroids?
Although, the exact reason for the formation of fibroids are obscure, medical professionals have determined certain factors that may affect their formation. Some of them are:
1) Hormones: Progesterone and estrogen, produced by the ovaries regenerate the uterine lining during each menstrual cycle and trigger the growth of fibroids.
2) Family history: If you have had a family history of uterine fibroids, then you&#x2019;re likely to develop the condition yourself as well.
3) Pregnancy: The production of progesterone and estrogen increases during pregnancy which increases the likelihood of fibroids.

What are the signs of the condition?
Depending on the location and size of the tumors, symptoms of such fibroids include:
1) Heavy bleeding and blood clots during periods
2) Pain in the pelvis
3) Frequent menstrual cramps
4) Pressure and pain in the lower abdomen
5) Swelling in the abdomen
6) Pain while intercourse

What is the procedure of the treatment?
Ultrasound and pelvic MRI are common diagnostic procedures to check for uterine fibroids. After diagnosis, depending on your age, size of the fibroid and your comprehensive health, the doctor would prescribe you with appropriate medications. Only after medications prove futile, doctors opt for minimally invasive surgeries.


Causes and Symptoms of Uterine Fibroids

Liver transplantation or hepatic transplantation is the second most carried out transplant procedure in the world. It is a potentially difficult surgery that is performed by a team of two to four surgeons along with the help of anesthesiologists and nurses. It takes around 10 to 12 hours to complete the procedure as there are many anastomoses, sutures, reconnections, and disconnections, which are to be performed under the liver bed which is necessary for the transplant to be a success.

Tests required before a transplant is planned

Computed tomography, or CT scan which employs X-rays and a computer to create pictures of the liver, showing its size and shape. CTs and chest X-rays are also recorded to evaluate your heart and lungs.
Laser Doppler flowmetry: to check if the blood vessels to and from the liver are normal.
Echocardiogram to check the status of heart function.
Pulmonary function test or lung capacity test to study and determine the lungs' ability to exchange oxygen and carbon dioxide.
Blood tests are performed to determine the patient's blood type, clotting ability, and biochemical status of blood, and to determine liver function.
The liver transplant procedure

After an admission at the hospital, an Intravenous line is started in the patient's arm or hand. Other tubes (catheters) are put in their neck and wrist, or their collarbone or the area between the belly and the thigh (the groin). These are used to check heart and blood pressure, and to get blood samples.
The patient is placed on the back, over the operating table.
If there is too much hair at the surgical site, it may be shaved.
A catheter is placed into the bladder to drain urine.
After the patient is sedated, the anesthesiologist will insert a tube into the lungs. This is done so that the breathing can be helped with a ventilator. The anesthesiologist will keep checking the heart rate, blood pressure, breathing, and blood oxygen level during the surgery.
The skin at the surgical site will be cleaned with a sterile (antiseptic) solution.
The doctor will make a cut (incision) just under the ribs on both sides of the belly.
The doctor will carefully separate the diseased or the injured liver from the nearby organs and structures.
The attached arteries and veins are then clamped to stop the blood flow into the diseased liver.
The diseased liver will be cut off from the blood vessels and then removed.
The surgeon will check the donor liver before implanting it into the body.
The donor's liver is placed in the patient's body.
The incision will then be closed with sutures or surgical staples.
