Breast Cancer - Categories It Can Be Classified Into!

Detecting a lump on your breasts can be stressful for any women. Breast cancer is a common type of cancer and is said to affect primarily affect women though 1% of breast cancer cases affect men. Breast cancer can be categorized into different types based on their capability to affect surrounding tissues.

The most common amongst these are:

  • Ductal carcinoma in situ
  • Invasive ductal carcinoma
  • Invasive lobular carcinoma

Breast cancer is caused by mutations of a person’s DNA cells. This could be inherited from one’s parents or acquired by an unhealthy lifestyle. These DNA mutations cause cells in the breast tissue to multiply rapidly and turn cancerous. The risk factors for breast cancer can be categorized as modifiable and non-modifiable.

Modifiable risk factors:

Non-modifiable risk factors:

  • Age
  • Family Medical History
  • Personal Medical History
  • Atypical hyperplasia
  • Early start of menstruation cycle
  • Presence of dense breast tissue
  • Inherited genetic mutations

As with any other type of cancer, the earlier it is diagnosed, the easier it is to treat. In its early stages, breast cancer is not painful and has negligible symptoms. In most cases, it is detected only by finding a lump on the breast or through a mammography. This lump may also be present in the armpit or above the collar bone. Some of the other symptoms of breast cancer include:

  • Nipple inversion
  • Discharge from the nipples
  • Changes in the colour and texture of skin covering the breast

Breast cancer has five stages beginning from 0 and going up to 4. This is based on the size of the tumour, involvement of lymph nodes and whether or not metastasis has occurred.

  • Stage 0: At this stage, the tumour does not affect the lymph nodes and has not metastasized. Thus at this stage, it is noninvasive.
  • Stage I:  In this case the tumour is smaller than 2 cm in diameter and has not spread to any of the surrounding tissues.
  • Stage II: In this stage, the cancerous tumours are still fairly small in size but also affect the surrounding lymph nodes.
  • Stage III: These tumours are larger than 5 cm in diameter and involve the lymph nodes to a greater extent.
  • Stage IV: This is also known as metastatic breast cancer. In this stage, the cancer cells metastasize to other parts of the body.

Surgery is the most preferred form of treatment for breast cancer. This may be combined with radiation, chemotherapy, targeted therapy or hormone therapy depending on the stage and type of cancer, the patient's overall health, age and personal preferences.

What is The Purpose Behind Brain Surgery?

What is The Purpose Behind Brain Surgery?

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.

Purpose:
Brain surgeries are performed to:

  1. Remove the brain tissues that are grown abnormally
  2. Aneurysm is clipped to prevent flow of blood cliff off an aneurysm
  3. Biopsy purpose or to remove the tumour
  4. Make a nerve free
  5. Drain the abnormal blood or clot collection or to drain any excessive fluid collection caused by infection.
  6. To implant artificial electronic device as a treatment for conditions like Parkinson's disease

Types:

  1. Biopsy: A part of brain tissue is removed for the brain or whole tumour is removed.
  2. Craniotomy: The skull bone is opened to remove tumour, an aneurysm and drain fluid or blood from infection.
  3. Minimally invasive endonasal endoscopic surgery: Endoscopic devices are inserted through the nose to remove the lesions or tumour.
  4. Minimally invasive neuroendoscopy: Similar to endonasal surgery but small incision is made.

Risks:

  1. Anaesthesia risks like breathing difficulty, allergic reaction to medications, excessive bleeding or clots and infection.
  2. 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.
  3. General risks include muscle weakness, disturbances in memory, speech, vision, coordination, balance and other functions that are controlled by the brain.

In case you have a concern or query you can always consult an expert & get answers to your questions!

Facts Of Human Brain

MBBS,CCA,DCA,AASECT,FPA,AAD,F.H.R.SM.I.M.S
General Physician, Gorakhpur
Facts Of Human Brain

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.

Treatment Of Uterine Cysts With Homeopathy

Uterine cysts are a type of cysts or tumours, which grow in the uterus. This is prevalent in women when they are near their childbearing years. Uterine cysts have some typical symptoms, which would let you know when to consult a medical practitioner for further help. It would cause excessive bleeding for a long duration of time. There is bleeding from the uterus in between your menstrual cycles. At times, it becomes very difficult to empty your bladder and irritation and discomfort are caused. It also leads to constipation. These are frequent symptoms, which accompany uterine cysts. These types of cysts are almost always non-cancerous, but it is beneficial to take an expert advice on that matter. Homeopathy is a great option to treat such cysts.

Homeopathy is becoming increasingly popular throughout the entire world. Now it is time to prove to the world what homeopathy can offer in surgical diseases. Homeopathic medicines cannot take the place of surgery but can be of great help to the patients who do not want to go for surgery or cannot be operated upon due to various medical reasons. There are specific medications to treat cysts through homeopathy.

Some of them are:

  1. Calcarea Carbonica: This medicine is suitable for those who bleed profusely during their menstrual cycle. Such excessive bleeding causes shivers and shrills in them, making them more prone to anaemia. In fact, excessive bleeding also influences their fertility cycles. This medicine is administered on overweight women who suffer from uterine cysts.

  2. Thlaspi Bursa Pastoris: This is prescribed to women who experience frequent menstrual cycles within short intervals. In fact, one does not even recover from the shock of the previous cycle and the new one starts. It is usually accompanied by excessive pain in the uterus. This medicine not only treats the cysts, but also the frequent period cycles and pain in the uterus.

  3. Trillium Pendulum: At times, due to excessive bleeding from the uterus, the patient suffers from fainting spells. Such cysts are also characterised by bright red blood flow during the menstrual cycle. These are the two main symptoms to administer this medicine on the individual.

  4. Fraxinus Americana: Apart from irregular periods with pain in the uterus, it is also followed by breaking down spells. One experiences cramps in the feet during this type of cyst. In such conditions, the best natural homeopathic therapy that can be administered is Fraxinus Americana.

  5. Calcarea Fluorica: This is a common medicine which is given to those patients who have extremely large tumours. These tumours are also characterised by their unique hardness.

Uterine cysts are a common problem in women and can be treated effectively. One needs to be alert about the symptoms and must immediately report to a specialized homeopathic practitioner for an effective administration of medicines, which may lead to a successful cure.

Cervicitis - 6 Common Symptoms

MBBS, DGO
Gynaecologist, Dehradun
Cervicitis - 6 Common Symptoms

The lower part of uterus, which eventually leads into the vagina in the female reproductive system in humans is called the cervix uteri or in simple words, cervix. The inflammation of this part of the reproductive system is called Cervicitis.

Causes

Inflammation in the cervix is caused due to irritation, infection or injury to the cells, which align the cervix. Any one of a number of infections, mainly sexually transmitted diseases can cause cervicitis, of which the most common are chlamydia , mycoplasma , ureaplasma and gonorrhea. Chlamydia accounts for almost 40% of the total cases. Less common causes of cervicitis are Trichomoniasis (Trichomonas vaginalis) and Genital herpes. Other than STDs, causes for Cervicitis include allergies, bacterial imbalance, injury or irritation resulting from pessaries, tampons, hormonal imbalance and even cancer or its treatment (radiation therapy).

Symptoms

Some cases of cervicitis in women can be symptomless. However, in most cases, symptoms are present, and they include:

1. Persistence of gray or white vaginal discharge that may or may not smell

2. Vaginal bleeding under certain conditions eg. in between periods or after sex

3. Pain during intercourse

4. Backache

5. Difficulty or pain during urination

6. In rare cases, fever or pain in the abdomen

Treatment

Cervicitis has no typical form of treatment. Treatment may not be needed in cases where the cause is not a sexually transmitted infection. On suspicion of an infection, the main objectives of the treatment are the removal of the infection and obstructing its spread to the fallopian tubes and uterus, or in case of pregnancy, to the baby.

The medical prescription issued by your doctor would depend on the organism, which is causing the infection. It may include Antibiotics, Antifungal medications or Antiviral medications. Cryosurgery, a process, which freezes the abnormal cells in the cervix using freezing temperatures, may also be performed by your doctor. In severe cases, where there is damage to the cervical cells, your doctor can apply silver nitrate (destroys abnormal cells).

Recommendations from your doctor may also ask your partner to be treated so as to prevent recurrence of the disease and to avoid intercourse as long as the treatment is in process. Treatment is mandatory if you are tested to be HIV positive. Moreover, having cervicitis makes you more prone to receive the virus from a HIV positive partner. If you wish to discuss about any specific problem, you can consult a gynaecologist.

How Can You Prevent Breast Cancer?

MD - Oncology
Oncologist, Hubli-Dharwad
How Can You Prevent Breast Cancer?

If you are concerned about breast cancer, you should know about the steps you can take to prevent the condition. Breast cancer is a type of cancer developing from the breast tissue. Symptoms such as a lump in the breast, fluid flowing from the nipple, changes in the shape of the breast and occurrence of red scaly patches on the breast denote breast cancer.

You need to make certain lifestyle changes in order to prevent breast cancer. The ways you should adopt include the following:

  1. Limit your alcohol intake: The more you consume alcohol, the more you put yourself at the risk of getting breast cancer. It is recommended for you not to drink more than one drink per day. Small amounts of alcohol increase the risk of breast cancer as well.

  2. Abstain from smoking: There is a direct link between tobacco smoking and breast cancer, and the risk is even more in premenopausal women. You should quit smoking to reduce the risk of breast cancer along with many other conditions, which can develop because of the ill-effects of smoking.

  3. Control your weight: Obese women are more prone to breast cancer when compared with women with a healthy weight. This is especially true when obesity occurs at a later stage in life, after menopause.

  4. Keep physically active: Regular physical activity is essential for you to maintain a healthy weight, which is important for preventing breast cancer. 150 minutes of moderate aerobic exercises or 75 minutes of vigorous exercises are recommended along with strength training.

  5. Breastfeed: Breastfeeding plays an important role in preventing breast cancer. The more you breastfeed your baby, the more protected you are from breast cancer.

  6. Limit the dosage and duration of hormone therapy: If you undertake combination hormone therapy for more than three to five years, you are at a higher risk of developing breast cancer. In case you are taking hormone therapy for menopausal symptoms, you should talk to your doctor about alternative options such as non-hormonal therapy and medications. If you still require hormonal therapy, you must use the lowest dose that will be effective.

  7. Avoid exposure to radiation and pollution: Certain medical imaging procedures like computerized tomography involves radiation of high doses. There is a link between breast cancer and radiation exposure. Thus, you should abstain from getting exposed to radiation and avoid taking such tests if it is not very urgent.

Maintaining a healthy diet also helps in reducing your risk of developing breast cancer. You should include food items which are plant based in your regular diet, such as fruits, vegetables, nuts, whole grains and legumes. Also, consume healthy fats such as olive oil instead of red meat and butter. If you wish to discuss any specific problem, you can consult an oncologist.

I am suffering from suffering from slip disk. What would be the best treatment for it?

DNB, Diploma in Medical Radio Diagnosis (DMRD)
Radiologist, Durg
Is it confirmed on MRI. If not you need to get an MRI done first. Then visit an orthopedic surgeon who would assess the severity of the condition. Minor bulges may be taken care off with medicine and lifestyle changes. However severe ones may require surgery depending on your health status.

Blocked Arteries - What Are The Reasons Behind?

Fellowship in Paediatric Cardiac Surgery, M. Ch. (CVTS), MS, MBBS
Cardiologist, Bangalore
Blocked Arteries - What Are The Reasons Behind?

Blockage in heart is a common term used for narrowing of coronary arteries. Coronary arteries are vessels, which supply blood and thus oxygen and food to continuously working heart muscles. Heart muscles, which are not tired working from the birth till death, however, cannot sustain long without blood supply.

A reduction in blood supply gives rise to ischemia of heart muscles commonly manifested as chest discomfort or angina. A sudden complete shutdown of blood supply leads to heart attack leading to permanent damage to heart (if blood flow not reestablished promptly).

But what causes these arteries to block? Sedentry lifestyle is the most primary reason of these blockages. Cigarette smoke increases the rate of atherosclerosis in the arteries of the heart, legs, and the aorta -- the largest artery in the body. Also, there is an increase in the risk of heart attack if a first-degree relative (parent or sibling) has had a heart attack or stroke. That is mainly seen when the relative has had a heart attack before the age of 45 if they are male, 55 if they are female. 

High levels of ''bad'' cholesterol, or low-density lipoprotein (LDL), are also the major contributors to arterial plaque formation. Having high blood pressure also increases the rate at which arterial plaque builds up. It also hastens the hardening of clogged arteries. LDL a normal component of blood (upto certain limit) starts depositing in arteries as early as 10 years of age!

Deposition of billions of LDL molecules over several years on inner surface of arteries gives rise to visible narrowings in these arteries. Flow ahead of these narrowings is reduced in proportion to the narrowing. At a level of 70 % narrowing the flow is reduced to give ischemia (and angina) during exercise. Gradually increasing degree of narrowing reduces the exercise needed for ischemia and angina; a narrowing of more than 90 % can give symptoms at rest. A sudden clot formation at any of these stages can block the flow suddenly giving a heart attack.

If LDL is a normal component of blood, why it is deposited in the arteries at first place?
LDL above a certain limit in blood starts depositing in the arteries. Diabetes, Hypertension, smoking, less exercise and genetics makes it more sticky thus making narrowing faster. This is why these risk elements need to be properly attended for prevention from heart disease. For treatment medicines are important for stopping the progression of narrowings; angioplasty is a method of fast resolution of blockage; and bypass surgery is the method of creating a whole new blood supply for the affected part of the heart. If you wish to discuss about any specific problem, you can consult a Cardiologist.
