Breast cancer is an abnormal growth of cells in the tissues of the breast. Mainly it occurs in females but less than 1% of all the breast cancer cases develop in males. The majority of breast cancers start in the milk ducts. A small number start in the milk sacs or lobules. It can spread to the lymph nodes and to the other parts of the body such as bones, liver, lungs and to the brain.
With more reliable early detection methods as well as the trend towards less invasive surgery, there is hope that even more women with breast cancer will be treated successfully and will go on to resume their normal lives.
Signs & Symptoms
It is painless, especially, during the early stage. Watch out for the following changes in the breast:
- A persistent lump or thickening in the breast or in the axilla.
- A change in the size or shape of the breast.
- A change in the colour or appearance of the skin of the breast such as redness, puckering or dimpling.
- Bloody discharge from the nipple.
- A change in the nipple or areola such as scaliness, persistent rash or nipple retraction (nipple pulled into the breast).
Consult a doctor immediately if you notice any of these changes.
Being a woman puts you at risk of getting breast cancer. There are certain factors that increase the risk of breast cancer. Some of them have been listed below:
- The risk increases with age; most cases of breast cancer develop after the age of 50
- Genetic alterations in certain genes such as BRCA1 and BRCA2
- Family history of breast cancer
- Being overweight
- Early menarche (onset of menstruation before the age of 12)
- Late menopause (after the age of 55)
- Never had children
- Late childbearing
- No breast feeding
- Excessive consumption of alcohol
- Use of hormonal replacement therapy (HRT) for a long period of time
However, most women who have breast cancer have none of the above risk factors. Likewise, not having any of these risk factors does not mean that you will not get breast cancer.
Early Detection and Screening
More treatment options are available when breast cancer is diagnosed at an early stage and hence the chances of recovery is also higher. So regular breast screening is important for early detection even if there are no symptoms. Following are the ways of screening:
- Breast Self-Examination (BSE): Perform BSE once a month about a week after your menses are over. If you no longer menstruate, choose a date each month which is easy to remember e.g. your date of birth or anniversary.
- Clinical Breast Examination: Get a breast specialist to examine your breast once a year if you are 40 years and above.
- Mammogram: Go for a screening mammogram once a year if you are 40 to 49 years old and once every two years if you are 50 years and above even if you do not have any symptom. It is not recommended for younger women (less than 40 years of age) as they have dense breasts, making it difficult for small changes to be detected on a mammogram. So ultrasonography of the breasts is advisable to them.
Types of Breast cancer
- Non-Invasive Breast cancer: These are confined to the ducts within the breasts. They are known as Ductal carcinoma in-situ (DCIS).
- Invasive Breast cancer: It occurs when cancer cells spread beyond the ducts or lobules. Cancer cells first spread to the surrounding breast tissue and subsequently to the lymph nodes in the armpit (Axillary lymph nodes). These cells can also travel to the other parts of the body such as bones, liver, lungs or brain and hence known as metastatic breast cancer.
Making A Diagnosis
If you notice any unusual changes in your breasts, you should see a doctor immediately. He will examine you clinically and may ask you to undergo some tests so that a definitive diagnosis can be made. Further, the staging work up is done to find out the stage of the disease and management accordingly.
Treatment of breast cancer may include various methods such as surgery with or without breast reconstruction, chemotherapy, radiation therapy, hormonal therapy and targeted therapy. Treatment options offered, depend upon the number of factors such as the stage of cancer and likelihood of cure, your general health and your preference.

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.
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. If you wish to discuss about any specific problem, you can consult a Neurosurgeon.
जिगर शरीर में सबसे बड़ा ग्रंथियों वाला अंग है और शरीर को विषाक्त पदार्थों और हानिकारक पदार्थों से मुक्त रखने के लिए विभिन्न महत्वपूर्ण कार्य करता है। पेट के दाहिने ऊपरी चतुर्भुज मंर स्थित है, पसलियों के ठीक नीचे। लिवर पित्त के उत्पादन के लिए जिम्मेदार है, जो एक पदार्थ है जो आपको वसा, विटामिन, और अन्य पोषक तत्वों को पचाने में मदद करता है। यह ग्लूकोज जैसे पोषक तत्वों को भी स्टोर करता है और दवाओं और विषाक्त पदार्थों को तोड़ता है।
लिवर कैंसर, जिसे हेपेटिक कैंसर भी कहा जाता है, एक कैंसर होता है जो लिवर में शुरू होता है। जब कैंसर लिवर में विकसित होता है, तो यह लिवर कोशिकाओं को नष्ट कर देता है और सामान्य रूप से कार्य करने के लिए लिवर की क्षमता में दखल देता है। लिवर कैंसर के दो प्रकार होते हैं। प्राथमिक लिवर कैंसर, जो लिवर की कोशिकाओं में शुरू होता है। जबकि, कैंसर जो कि कहीं और से शुरू होता है और अंततः जिगर तक पहुंच जाता है, उन्हें जिगर मेटास्टेसिस या द्वितीयक लिवर कैंसर कहा जाता है।
प्राथमिक लिवर कैंसर के विभिन्न प्रकार
विभिन्न प्रकार के प्राथमिक लिवर कैंसर लिवर के विभिन्न कोशिकाओं से उत्पन्न होते हैं। प्राथमिक लिवर कैंसर लिवर में एक गांठ के रूप में, या एक ही समय में लिवर के भीतर कई स्थानों में शुरू हो सकता है।
1. हेपैटोसेलुलर हेपैटोसेलुलर:
हेपेटोसेल्यूलर कार्सिनोमा (एच.सी.सी), जिसे हेपेटामा भी कहा जाता है, सबसे सामान्य प्रकार का लिवर कैंसर है। एचसीसी मुख्य प्रकार के लिवर कोशिकाओं में शुरू होता है, जिसे हेपोटोसेल्यूलर कोशिका कहा जाता है। एचसीसी के अधिकांश मामले हेपेटाइटिस बी या सी, या शराब के कारण जिगर के सिरोसिस के संक्रमण का नतीजा है।
2. फाइब्रोलैमेलर एचसीसी:
फाइब्रोलामेरेलर एचसीसी एक रेअर प्रकार का एचसीसी है, जो आम तौर पर अन्य प्रकार के लिवर कैंसर की तुलना में उपचार के लिए अधिक संवेदनशील होता है।
कोलेंजियोकार्सिनोमा, जिसे आमतौर पर पित्त नली के कैंसर के रूप में जाना जाता है, लिवर में छोटे, ट्यूब जैसे पित्त नलिकाओं में विकसित होता है। पाचन में मदद करने के लिए, ये नलिकाएं पित्ताशय में पित्त को ले जाने के लिए जिम्मेदार हैं। जब कैंसर लिवर के अंदर नलिकाएं के खंड में शुरू होता है, तो इसे इंट्राहेपेटिक पित्त नलिका कैंसर कहा जाता है। यद्यपि, जब लिवर के बाहर नलिकाओं के अनुभाग में कैंसर शुरू होता है, तो एक्स्ट्राहेपाटिक पित्त वाहिका कैंसर कहलाता है।
एंजियोनेसकोमा लिवर कैंसर का एक रेअर प्रकार है जो लिवर के रक्त वाहिकाओं से शुरू होता है। इस प्रकार का कैंसर बहुत तेज़ी से प्रगति करता है, इसलिए यह आमतौर पर एक और अधिक उन्नत चरण में डिटेक्ट किया जाता है।
हेपोटोब्लास्टोमा एक अत्यंत असामान्य प्रकार का लिवर कैंसर है।
लिवर कैंसर के लक्षण
ज्यादातर लोगों के प्राथमिक जिगर कैंसर के शुरुआती चरणों में लक्षण नहीं होते। जिसके परिणामस्वरूप, लिवर कैंसर बहुत देर से डिटेक्ट किया जाता है। लिवर कैंसर के लक्षणों में शामिल हैं:
- भूख में कमी
- वजन घटना
- एबडोमीनल पेन
- मतली और उल्टी
- सामान्य खुजली
- हेपटेमेगाली (बढ़े हुए जिगर)
- बढ़े हुए स्प्लीन
चूंकि लिवर कैंसर के लिए कोई व्यापक रूप से अनुशंसित नियमित स्क्रीनिंग टेस्ट नहीं हैं, इसलिये बीमारी के परिवार के या अन्य जोखिम कारकों के इतिहास वाले लोगों को उनके डॉक्टर से बात करनी चाहिए ताकि वे अपने जोखिम को मॉनिटर करने या कम करने के लिए सही कदम उठा सकें।
लिवर कैंसर के जोखिम कारक
प्राथमिक लिवर कैंसर के खतरे को बढ़ाने वाले कारकों में शामिल हैं:
- उपचय स्टेरॉयड्स
- कम प्रतिरक्षा और मोटापा
Age 51 years male. Slip disc happened jan'2010 and get to normal after 4 years doing only exercise till now and used lumbo scrarol belt when out of home. Due to filling uneasy during walking, a tmt brace protocol suggested. Is it ok to do the test.
A brain stroke can affect anyone at any point of time when the supply of blood to the brain is interrupted. It can threaten major physical functions and can prove to be fatally dangerous at times. The brain stem which is placed right above the spinal cord controls the breathing, heartbeat and levels of blood pressure. It is also in charge of controlling some elementary functions such as swallowing, hearing, speech and eye movements
What are the different types of strokes?
There are three main kinds of stroke: ischemic strokes, hemorrhagic strokes and transient ischemic attacks. The The most common type of brain stroke is the ischemic stroke is caused by narrowing or blocking of arteries to the brain, which prevents the proper supplyof of blood to the brain. Sometimes it so happens that the blood clot that has formed elsewhere in the body have travelled via the blood vessels and has been trapped in the blood vessel which provides blood to the brain. When the supply of blood to a part of the brain is hindered, the tissue in that area dies off owing to lack of oxygen. The other variant of brain stroke is termed as hemorrhagic stroke is caused when the blood vessels in and around the brain burstor or leak. Strokes need to be diagnosed and treated as quickly as possible in order to minimize brain damage.
What are the common symptoms of a brain stroke?
The symptoms of the brain stroke are largely dependent on the area of the brain that has been affected. It can interfere with normal functioning, such as breathing and talking and other functions which human beings can perform without thinking such as eye movements or swallowing. Since all the signals from the brain as well as other parts of the body traverse through the brain stem, the interruption of blood flow often leads to numbness or paralysis in different parts of the body.
Who is likely to have a stroke?
Anyone is at a risk of developing brain stroke although ageing is directly proportional to the risk of having a stroke. Not only that an individual with a family history of brain stroke or transient ischemic attack is at a higher risk of developing stroke. People who have aged over 65 accounts for about 33 percent of all brain strokes. It is important to point here that individuals with high blood pressure, high blood sugar, cholesterol, cancer, autoimmune diseases and some blood disorders are at a higher risk of developing brain stroke.
There are a few factors which can increase the risk of developing stroke beyond any control. But there are certain lifestyle choices as well which aids in controlling the chances of being affected by stroke. It is crucial to refrain from long-term hormone replacement therapies as well as birth control pills, smoking, lack of physical activity, excessive use of alcohol and drug addiction. A brain stroke is a life-threatening medical condition, and when an individual has symptoms that resemble that of stroke, it is crucial to seek immediate medical help.
Treatment for stroke:
- Treatment depends on the type of stroke.
- Ischemic strokes can be treated with 'clot-busting' drugs.
- Hemorrhagic strokes can be treated with surgery to repair or block blood vessel weaknesses.
- The most effective way to prevent strokes is through maintaining a healthy lifestyle.
What is TPA?
TPA is a thrombolytic or a “Clot Buster” drug. This clot buster is used to break-up the clot that is causing a blockage or disruption in the flow of blood to the brain and helps restore the blood flow to the area of the brain. It is given by intravenous (IV). This can be given only within 45.5 hrs of the onset of symptoms
Time is brain
Remember Every second Loss means brain cells die.
Rush to the nearest Stroke Centre whenever you experience such symptoms.
You can save the brain cells dying if you reach within 45.5 hrs by the CLOT BUSTER.
Another treatment option is an endovascular procedure called mechanical thrombectomy, strongly recommended, in whichtrained trained doctors try removing a large blood clot bysending sending a wired-caged device called a stent retriever, to the site of the blocked blood vessel in the brain
The good news is that 80 percent of all strokes are preventable. It startswith with managing keyrisk risk factors, including
- High blood pressure,
- Cigarette smoking,
- Diabetes Atrial fibrillation and
- Physical inactivity.
More than half of all strokes are caused by uncontrolled hypertension or high blood pressure, making it the most important risk factor to control.
The best way to get better after a stroke is to start stroke rehabilitation ("rehab"). In stroke rehab, a team of health professionals works with you to regain skills you lost as the result of a stroke. If you wish to discuss about any specific problem, you can consult a neurologist.
I am a 38 year old married lady with 2 kids. I have herniated disc of l5 s1 with mild detention as detected in mri. What is the treatment? I am really scared. Is it dangerous?
Lung cancer occurs at slightly younger age in women than in men. Adenocarcinoma is the commonest type of lung cancer in women. It warrants testing for some molecular markers which form the basis of targeted therapies. Thus lung cancer in women behaves biologically and clinically different from that in men
Women should take care of their health, stay away from tobacco and think positive
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. If you wish to discuss any specific problem, you can consult a physiotherapist.
I am 20yr old male. I had an accident 2 years ago & I had suffered severe back pain. My spinal cord's disc had moved a bit so that I have pain in my back till now. What should I do for this?
The most powerful and amazing organ in our body is the brain. It differs from many other organs of our body not only by its shape, but also by its special type of cell called neurons. When these cells gets affected or dead it can never be reverted or regenerated which is the most exclusive nature found only in brain cells. The cells in other parts of our body has the capacity to regenerate (can be replaced or new one can be grown or produced), but brain cells are exception. Hence any damage to the brain, injury or trauma is really a crucial thing to be considered with utmost care.
Brain surgeries really need skill, proper training, confidence and intelligence to perform this highly complicated and risky surgery.
Brain surgeries are performed to:
- Remove the brain tissues that are grown abnormally
- Aneurysm is clipped to prevent flow of blood cliff off an aneurysm
- Biopsy purpose or to remove the tumour
- Make a nerve free
- Drain the abnormal blood or clot collection or to drain any excessive fluid collection caused by infection.
- To implant artificial electronic device as a treatment for conditions like Parkinson’s disease
- Biopsy: A part of brain tissue is removed for the brain or whole tumour is removed.
- Craniotomy: The skull bone is opened to remove tumour, an aneurysm and drain fluid or blood from infection.
- Minimally invasive endonasal endoscopic surgery: Endoscopic devices are inserted through the nose to remove the lesions or tumour.
- Minimally invasive neuroendoscopy: Similar to endonasal surgery but small incision is made.
- Anaesthesia risks like breathing difficulty, allergic reaction to medications, excessive bleeding or clots and infection.
- Risk related to the brain surgeries are seizures, coma, swelling of brain, infection to brain or meanings, surgical wound infection that intrudes to the brain structures, abnormal clot formation and bleeding.
- General risks include muscle weakness, disturbances in memory, speech, vision, coordination, balance and other functions that are controlled by the brain. If you wish to discuss about any specific problem, you can consult a neurosurgeon.
