The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered.
Nerve impulses to and from the brain travel as fast as 170 miles per hour. Ever wonder how you can react so fast to things around you or why that stubbed toe hurts right away? it’s due to the super-speedy movement of nerve impulses from your brain to the rest of your body and vice versa, bringing reactions at the speed of a high powered luxury sports car.
The brain operates on the same amount of power as 10-watt light bulb. The cartoon image of a light bulb over your head when a great thought occurs isn’t too far off the mark. Your brain generates as much energy as a small light bulb even when you’re sleeping.
The human brain cell can hold 5 times as much information as the encyclopedia britannica. Or any other encyclopedia for that matter. Scientists have yet to settle on a definitive amount, but the storage capacity of the brain in electronic terms is thought to be between 3 or even 1, 000 terabytes. The national archives of britain, containing over 900 years of history, only takes up 70 terabytes, making your brain’s memory power pretty darn impressive.
Your brain uses 20% of the oxygen that enters your bloodstream. The brain only makes up about 2% of our body mass, yet consumes more oxygen than any other organ in the body, making it extremely susceptible to damage related to oxygen deprivation. So breathe deep to keep your brain happy and swimming in oxygenated cells.
The brain is much more active at night than during the day. Logically, you would think that all the moving around, complicated calculations and tasks and general interaction we do on a daily basis during our working hours would take a lot more brain power than, say, lying in bed. Turns out, the opposite is true. When you turn off your brain turns on. Scientists don’t yet know why this is but you can thank the hard work of your brain while you sleep for all those pleasant dreams.
Scientists say the higher your i. q. The more you dream. While this may be true, don’t take it as a sign you’re mentally lacking if you can’t recall your dreams. Most of us don’t remember many of our dreams and the average length of most dreams is only 2-3 seconds–barely long enough to register.
Neurons continue to grow throughout human life. For years scientists and doctors thought that brain and neural tissue couldn’t grow or regenerate. While it doesn’t act in the same manner as tissues in many other parts of the body, neurons can and do grow throughout your life, adding a whole new dimension to the study of the brain and the illnesses that affect it.
Information travels at different speeds within different types of neurons. Not all neurons are the same. There are a few different types within the body and transmission along these different kinds can be as slow as 0.5 meters/sec or as fast as 120 meters/sec.
The brain itself cannot feel pain. While the brain might be the pain center when you cut your finger or burn yourself, the brain itself does not have pain receptors and cannot feel pain. That doesn’t mean your head can’t hurt. The brain is surrounded by loads of tissues, nerves and blood vessels that are plenty receptive to pain and can give you a pounding headache.
80% of the brain is water. Your brain isn’t the firm, gray mass you’ve seen on tv. Living brain tissue is a squishy, pink and jelly-like organ thanks to the loads of blood and high water content of the tissue. So the next time you’re feeling dehydrated get a drink to keep your brain hydrated.
Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs. These abnormal cells do not carry out the functions of normal lung cells and do not develop into healthy lung tissue. As they grow, the abnormal cells can form tumors and interfere with the functioning of the lung, which provides oxygen to the body via the blood.
Lung cancer is the most common cause of death due to cancer in both men and women throughout the world. According to the U.S. National Cancer Institute, approximately one out of every 14 men and women in the U.S. is diagnosed with cancer of the lung at some point in their lifetime. Lung cancer is predominantly a disease of the elderly; almost 70% of people diagnosed with lung cancer are over 65 years of age, while less than 3% of lung cancers occur in people under 45 years of age.
What Causes Lung Cancer?
The development of lung cancer is strongly associated with cigarette smoking, approximately 90% of lung cancers are attributable to use of tobacco. Pipe and cigar smoking can also cause lung cancer, but the risk is not as high as with cigarette smoking. Tobacco smoke contains more than 4,000 chemical compounds, many of which are cancer causing (carcinogens). Passive smoking, i.e. the inhalation of tobacco smoke by non-smokers who live or work with smokers, is also an established risk factor for the development of lung cancer.
Genetic susceptibility (i.e. family history) may play a role in the development of lung cancer. Other causes of lung cancer include air pollution (from vehicles, industry, and power generation) and inhalation of asbestos fibres (usually in the workplace).
Lung Cancer Symptoms:
Early symptoms and signs of lung cancer:
There may be no symptoms at the onset of the disease. When present, common symptoms of lung cancer may include:
- Coughing: This includes a persistent cough that doesn't go away or changes to a chronic smoker's cough, such as more coughing or pain.
- Coughing up blood: Coughing up blood or rust-colored sputum (spit or phlegm) should always be discussed with your doctor.
- Breathing Difficulties: Shortness of breath, wheezing or noisy breathing (called stridor) may all be signs of lung cancer.
- Loss of Appetite: Many cancers cause changes in appetite, which may lead to unintended weight loss.
- Fatigue: It is common to feel weak or excessively tired.
- Recurring infections: Recurring infections, like bronchitis or pneumonia, may be one of the signs of lung cancer.
Signs of advanced stages of lung cancer: Advanced stages of lung cancer are often characterized by the spread of cancer to distant sites in the body. This may affect the bones, liver or brain. As other parts of the body are affected, new lung cancer symptoms may develop, including:
- Bone pain
- Swelling of the face, arms or neck
- Headaches, dizziness or limbs that become weak or numb
- Lumps in the neck or collar-bone region
Treatment: Treatment for cancer involves a combination of surgery to remove cancer cells, chemotherapy and radiation therapy to kill cancer cells. Lung cancer is incurable unless complete surgical removal of the tumour cells can be achieved. Surgery is the most effective treatment for lung cancer, but only a few percentage of lung cancers are suitable for surgery i.e. Stage I and II NSCLC and cancer that has not spread beyond the lung.
Radiation therapy may be used for both NSCLC and SCLC and is a good option for people who are not suitable for surgery or who refuse surgery. Chemotherapy is used for both NSCLC and SCLC. Chemotherapy drugs may be given alone or in combination with surgery or radiation therapy. Chemotherapy is the treatment of first choice for SCLC since it has usually spread extensively in the body by the time it has been diagnosed.
Also used in the treatment of lung cancer are targeted therapies. These are drugs (gefitinib and erlotinib) or antibodies (cetuximab, bevacizumab) that block the growth and spread of cancer by interfering with specific molecules involved in tumor growth and progression. They are used in some patients with NSCLC that does not respond to standard chemotherapy.

Breast cancer is a form of cancer which develops from the breast tissue. Breast cancer is indicated by signs such as a lump in the breast, changes in breast shape, fluid flowing from the nipple, dimpling of skin, or the development of red scaly patches. Breast cancer is a fatal form of cancer in women and immediate diagnosis is required on observing the symptoms.
Diagnosis of breast cancer
Other than the regular breast screening, the diagnosis of breast cancer involves the following steps and methods:
- Seeing your general practitioner (GP): It is very important to visit your GP soon after noticing the symptoms of breast cancer. Your GP will examine you properly and in case your symptoms need more assessment, he/she will refer you to a breast cancer clinic.
- Mammogram and breast ultrasound: You will be required to have a mammogram, as recommended by a specialist breast unit. This is an X-ray of the breasts. An ultrasound scan may also be required. Breast ultrasound should be undertaken only if you are less than 35 years of age. This is because, young women have denser breasts and a mammogram is not as effective as ultrasound in the diagnosis of breast cancer. In ultrasound, high frequency sound waves are used for obtaining an image of your breasts. It is observed to notice any abnormality or lumps. A breast ultrasound is also important for determining whether a lump is solid or contains liquid.
- Biopsy: In this diagnosis process, a sample of the tissue cells is taken from the breasts and tested under a microscope to find out if it is cancerous. A scan and needle test for the lymph nodes present in your armpit is also done to check whether they have also been affected. A biopsy is undertaken in several ways, depending upon the condition and severity. A needle aspiration biopsy is used for testing a sample of your breast cells without the removal of the tissues. This is the most common form of biopsy and it is also used for draining a small fluid-filled lump or benign cyst. During the process, you will be given a local anesthetic. Usually, a needle biopsy is carried out guided by an X-ray, ultrasound and an MRI scan as well. This helps in distinguishing it from non-invasive changes such as ductal carcinoma in situ.
Another form of biopsy used for the diagnosis of breast cancer is called vacuum assisted biopsy or mammotome biopsy. In this process, a needle gets attached to a suction tube, which helps in obtaining the sample and for clearing the bleeding. If you wish to discuss about any specific problem, you can consult a general-surgeon.
Breast cancer, is a type of cancer, which is common to women, where cancer cells grow on the breasts or the female mammary gland. It starts out with the formation of a small lump in your breast and can spread out to your other organs very rapidly. It generally affects women above forty years of age. Breast cancer can be classified into two types. They can either start forming on the inner linings of your milk ducts ( known as Ductal carcinoma) or in the lobules which supply milk (known as Lobular carcinoma).
There are many causes responsible for breast cancer they are mentioned below:
- Obesity or post-menopausal obesity (Learn more about Heart Diseases Post Menopause)
- Exposure to frequent radiation (X-ray)
- Consumption of alcohol
- Being taller than average
- Start of periods at an early age
- Late menopause
- Hormone replacement therapy
- Consumption of birth control pills
The most common symptoms of breast cancer are as follows:
- Formation of a lump in your breast
- Swelling or shrinking of your breast
- Change of size, shape and color of your nipple
- Blood or milk discharge from the nipple
- Breast pain
- Itching sensation
- Appearance of rashes (Learn more about to maintain the skin health)
Breast cancer if not diagnosed and treated at an early stage may turn out to be fatal. Ayurveda offers promising cures for breast cancer.
A few of the Ayurvedic remedies are mentioned below:
- Include foods, which are well supplied with vitamin D in your diet. Researches show that women with less amount of vitamin D in their bodies are more likely to develop breast cancer. Consider including foods like eggs, orange juice, dairy products and fish like salmon in your diet.
- Drink more of green tea as it has anti cancer properties.
- Exercises like walking, yoga, meditation and certain breast exercises can help you to relax the pain sensation, reduce stress and also get cured.
- Incorporate bitter gourd in your diet. Researches show that bitter gourd can kill those cancer cells, which cause breast cancer.
- Ayurvedic herbs like Ashwagandha, tulsi, curcumin have certain properties that can destroy cancer cells.
Since, breast cancer has less survival rates, it is absolutely essential for you to visit an Ayurvedic practitioner if you wish to get cured through Ayurvedic treatment.
Breast cancer is a type of cancer which occurs due to the development of cancerous cells in a person's breasts. Women are usually affected by breast cancer and breast cancer is one of the most common forms of cancer after skin cancer. Usually fatal if not diagnosed in its early stage, breast cancer is a very serious medical ailment. Read on more to find all about the different symptoms, causes, preventive measures and treatment of breast cancer.
Breast cancer has a few distinct characteristics and if you have a few or all the following symptoms you could be more likely to suffer from breast cancer.
- The formation of a lump in your breast which is different from the surrounding tissue and usually more thickened.
- The discharge of bloody fluid material from the nipples.
- Sudden change of the size, shape and appearance of the breast.
- Certain distinct changes to the skin over the breast for example an indentation in the skin similar to that of a dimple.
- Appearance of an extra nipple which is inverted.
- If the darkened area around the nipples known as the areola is flaking or peeling off.
Studies and researches remain inconclusive on what causes breast cancer. Breast cancer occurs due to abnormal division of the cells located in the breast which over time accumulate and form lumps. They
might spread to other parts of the body. Breast cancer is caused mainly due to a complex interaction of personal genetics, environment and lifestyle choices. Breast cancer can also be caused due to genetics as about 5% to 10% of cases are due to gene mutations which pass onto generations.
There are certain factors which increase the probability of contracting breast cancer. Increasing age, personal and family history of breast cancer, obesity, radiation exposure, pregnancy at an older age, post-menopausal hormone therapy are some of the factors that increase the chances of breast cancer.
Several forms of surgical methods exist to treat breast cancer. Depending on the condition and spread of the disease a suitable surgery is performed. These include mastectomy, lumpectomy, axillary lymph node dissection and removal of both breasts. Other forms of treatment include chemotherapy or the use of high doses of drugs to destroy cancerous cells. Radiation therapy where X-rays are used to destroy the cancer cells is also effective. If you wish to discuss about any specific problem, you can consult a Gynaecologist.
What is Bone cancer?
Bone cancer is malignant tumour of the bones which can spread to lungs or other parts of the body. It may have arisen primarily from the bone itself (primary bone cancer) or more commonly, may have spread to the bones (secondary bone cancer) from cancer of some other body organ like Breast cancer, Prostate cancer etc.
Primary bone cancer usually occurs in growing children and young adolescents, whereas, secondary bone cancer usually occurs in older age group. Usually, the patient experiences pain in the affected area, which over the time, gets worse and continuous. There may also be swelling in the involved region. It can cause weakening of bones resulting in fracture. Some patients may attribute these symptoms to any prior antecedent trauma. Unintentional weight loss may also be seen. Sometimes, these patients are wrongly being treated for infection, thus delaying the correct treatment which may have a bearing on the final outcome.
How common is bone cancer?
Secondary bone cancer is the most common type of bone cancer with bone being the third most common site of cancer spread (metastasis) from other organs. However, primary bone cancers are rare accounting for less than 1% of all cancers.
Causes of bone cancer?
There are no known environmental or other hereditary factors which cause bone cancer, however, certain patients are at a greater risk for bone cancer which include:
- Patients who have received prior radiation therapy
- Patients with a history of Paget’s Disease
- Patients with hereditary retinoblastoma - a type of eye cancer that most commonly affects very young children
- Patients with Li-Fraumeni syndrome - a rare genetic condition
How is it diagnosed?
A patient suspected with bone cancer needs to be investigated thoroughly with blood tests, Xrays, MRI to look for local extent of disease. Since bone cancer can spread to lungs and other bones, staging of the disease is done either with whole body PET CT or a bone scan with CT Chest. Alongwith that, a biopsy (usually with a needle) is required to establish the diagnosis. It’s important to do biopsy from the correct site since wrong biopsy site can be detrimental in limb salvage and can result in amputation (cutting the limb). Therefore, it’s recommended that the biopsy should always be done by the surgeon (Orthopaedic Oncologist) who will be doing the final surgery for bone cancer.
Treatment of bone cancer is a multidisciplinary approach requiring an Orthopaedic Oncologist (Bone & Soft tissue tumour specialist), Medical Oncologist (Chemotherapy Specialist), Radiation Oncologist (Radiotherapy specialist) and Pathologist (Specialist in tissue diagnosis).
Usually in primary bone cancers, chemotherapy is given to the patient followed by surgery to remove the diseased bone which is further followed by adjuvant chemotherapy. Limb salvage surgery is possible nowadays for bone cancers in which the part of the bone involved with tumour is removed surgically (rather than cutting the whole limb) and the defect is reconstructed with artificial joint, thereby saving the limb. In some cases, the cancerous bone so removed is given very high dose of radiation so as to kill all the cancer cells and the sterilised bone so formed is fixed back to the parent bone with the help of plates and screws, a technique commonly called as Extra Corporeal Radiation Therapy (ECRT). In children, since the artificial joint will not grow as the child grows leading to unequal limb lengths over a period of time, the defect can be reconstructed with expandable joint which can be lengthened as the child grows which allows to maintain limb length equality at the time of skeletal maturity.
Is cure possible in bone cancer?
With the current chemotherapy regimes and advanced surgical technology, cure is possible in upto 70-75% patients with primary bone cancer. In patients with secondary bone cancer, cure can still be achieved depending upon the primary cancer and the extent of disease. In advanced cases also, a lot can be done to control the disease and give a quality of life to the patient.
Is it possible to prevent bone cancer?
Since the exact cause of bone cancer is not known, as of now it’s not possible to prevent bone cancer.
Whom to consult?
First chance is the best chance when it comes to curing bone cancers. So, it’s advisable to seek treatment from a trained Orthopaedic Oncologist when confronted with a bone cancer to achieve maximum beneficial outcome.
If you are concerned about liver cancer, you should know that most people do not experience signs and symptoms of the cancer in the early stages. Liver cancer is a form of cancer which occurs in the cells of the liver. There are various types of cancer which can develop in the liver. Hepatocellular carcinoma (HCC) is the most common liver cancer which begins in the hepatocyte, which is the main liver cell.
Usually there are no specific primary stage symptoms of liver cancer. Some symptoms which may develop include the following:
Unusual weight loss is observed
Loss of appetite and developing food aversion
Pain in the upper abdomen
General weakness with intense fatigue
Swelling in the abdomen
The skin may become yellow
White and chalky stools are likely
In most cases, the causes of liver cancer cannot be clearly determined. In some cases, the cause is known, such as chronic infection with the hepatitis virus, which may lead to liver cancer. Liver cancer occurs when the liver cells undergo changes or mutations in their DNA structure. DNA mutations lead to changes in instructions of chemical processes taking place in the body. The cells may grow out of control and develop into a cancerous tumour.
There are several factors which enhance the risk of liver cancer. They are as follows:
A progressive and irreversible condition known as cirrhosis leads to scar tissue formation in the liver, increasing the risk of liver cancer.
Certain inherited liver diseases such as Wilson’s disease and hemochromatosis also increase the chances of liver cancer.
People with diabetes are also at a greater risk of having liver cancer.
Non-alcoholic fatty liver disease (NAFLD), which is the accumulation of fat in the liver, also increases the chances of getting this condition.
Excessive alcohol consumption is another factor which causes irreversible damage to the liver and the chances of getting liver cancer get boosted.
Exposure to aflatoxins, which are poisons produced by molds growing on poorly stored crops, make you more likely to get liver cancer.
Several tests and procedures are carried out for the diagnosis of liver cancer. These include blood tests for diagnosing liver function problems, and imaging tests such as ultrasound, CT scan and MRI scan.
The uterus is a muscular structure held in place inside your pelvis with the help of muscles, ligaments, and tissues. These muscles weaken in women due to pregnancy, childbirth or delivery complications and can lead to severe complications. One such complication is a uterine prolapse. Uterine prolapse occurs when the uterus sags or slips from its normal position into the vaginal canal.
The causes of uterine prolapse are varied and include:
- Delivering a large baby
- Difficulty in labor and delivery
- Reduction in estrogen levels post menopause
- Traumatic childbirth
- Loss or weakening of the pelvic muscle
- Conditions which lead to increased pressure in the abdominal area such as a chronic cough, straining, pelvic tumors or accumulation of fluid in the abdomen
- Loss of external support due to major surgery in pelvic area
Uterine prolapse can be complete or incomplete depending on how far the uterus sags into the vagina. Women who have minor uterine prolapse may not have any visible symptoms. However, if the condition worsens, it manifests itself in visible signs.
Symptoms of moderate or severe prolapse are:
1. A feeling of fullness or pressure in your pelvis when you sit
2. Seeing the uterus or cervix coming out of the vagina
3. Vaginal bleeding or increased discharge
4. Painful sexual intercourse
5. Recurrent bladder infections
6. Continuing back pain with difficulty in walking, urinating and moving your bowels
Without proper attention, the condition can cause impairments in the bowel, and can also affect bladder and sexual function.
