Medical science constantly challenges the boundaries by finding not only the cures to the most dangerous diseases, but finds a way to prevent them even before they occur. With years of research, practice and data available for analysis, scientists are using advanced technology in combination with years of research to create a predicting mechanism for often fatal diseases like cancer.
Breast cancer screening has always been done with mammography. The fact is that this method is only 75% accurate, laden with false positives and misses a whole set of women totally- and that too when cancer has already developed. Part of the problem comes from the dense breast tissue which one in three women have. This tissue masks the lumps, which makes it difficult for mammograms to accurately screen cancer.
Some breakthrough scientific methods are changing this by drawing on years of research to predict this deadly disease, years before it can manifest itself.
A genetic test to predict cancer 10-11 years ahead of time. This test was performed to see how environmental factors could influence cancer, along with habits like smoking, abusing alcohol or hormones, genetic changes that occur and are put a large percentage of the women at a high risk of developing this disease.
A simple blood test is used for the genetic analysis of hereditary cancer. Researchers found a biological marker, methylation of the ATM gene, which has a very high ability to predict the risk of developing cancer, several years before diagnosis. 'Methylation' concluded that when one biological indicator is exposed to carcinogenic substances, or other abusive substances like tobacco and alcohol, it may trigger the development of cancer. On the flip side, this test will take time to reach the commercial market and even then cannot give an exact timeline as to when someone may develop the disease.
A simple blood test to predict breast cancer 5 years before it develops. This is the kind of medical miracle the world is looking for. Last year in April, researches in Denmark identified a simple blood test that can predict breast cancer five years before it actually develops with an accuracy of a whopping 80%.
It works by "measuring all of the compounds in the blood to build a 'metabolic profile' of an individual, in order to detect changes in the way chemicals are processed, during a pre-cancerous stage," says Laura Donnelly, health editor at The Telegraph, which covered this development. Danish researchers observed 57,000 participants over 20 years, gathering blood samples along the way, specifically comparing a set of 800 women who remained healthy or developed breast cancer within 7 years of their first blood sample. The researchers found they were able to predict, with 80 percent accuracy, which patients would be affected by the disease, just by looking at the metabolic profiles they built from the participants' blood samples. The results have been published in Metabolomics. If you wish to discuss about any specific problem, you can consult a Gynaecologist.
The pain which a person experiences as a result of having a herniated disc can be quite debilitating, to tell you the truth. However, taking into due account the fact that all a person in such a situation would want would be to be up and running as soon as possible.
In order for this to happen, as would be expected, he or she would need to go through the options which are available for treatment of a herniated disc. There are various types of herniated disc treatments which are available though it can be said that conservative treatments are preferred as these treatments do not require surgery to be carried out on the person who is suffering from the issue.
The course of this sort of treatment lasts somewhere between one month to one and a half months. The aim of conservative treatment is to reduce or minimise the pain that is automatically associated with a herniated disc. There is a strategy to help a person improve by which he or she is provided with medicine for the purpose of pain relief while physiotherapy is made use of to make the underlying condition better.
Surgical treatment may be required, if the case is such that the person has lost a great degree of function and is in pain that seems to be pretty much unbearable. `If the person has a lumbar herniated disc, then the conservative treatment for this sort of case would require him or her to apply ice and heat from a warm source to provide relief to the area. If the pain is very bad yet the person is determined not to undergo surgery then the answer would be to consume some oral steroids or narcotic pain medications. One should surely keep in mind that this is only to carried out as per the prescription of a doctor who is trained and experienced to a sufficient degree.
If surgery is required for this sort of herniated disc, then it is likely to be a lumbar decompression surgery which aims to allow for the growth of the spine back to health as a result of removing the herniated disc. When it comes to cervical herniated disc treatment, conservative solutions include using drugs like ibuprofen and physical therapy; similar to solving lumbar herniated discs. However, surgical treatment for cervical herniated discs warrants anterior cervical decompression; where the disc is removed from the front of the neck. If you wish to discuss about any specific problem, you can consult a Physiotherapist.
Dear sir /madam My recent whole spine MRI shows cervical discs are black colour less fluid which dehydrated and my ulnar nerve getting compression with numbness in little & ring finger Kindly suggest the best medicine for my problem Thanking in advance.
You know that feeling after a long day when your feet are so sore or swollen that you can’t bear the thought of standing on them for any longer? once you take off your shoes and sit down, or even soak them in a warm bath, it’s still an unpleasant experience. Luckily, I’ve collected 10 natural remedies for such an occasion and I want to share them with you.
Important: regular swelling vs potential health risks
When experiencing swelling in the feet and legs, apply pressure to the area with a finger. If the dimple created by the finger remains for more than a couple of seconds, it may indicate oedema, which can be the result of heart, liver, or kidney problems. When this occurs, see a doctor at the first possible opportunity.
If you experience swelling in one leg but not the other, you should also see a doctor as this may be an indication of deep venous thrombosis (a blood clot blocking the blood vessels).
If the swelling is accompanied by shortness of breath, fever, bluish skin, and chest pains, get immediate medical attention.
10 natural remedies:
1. Soak your feet in epsom salts
Pour 250g of epsom salt into a hot bath, and take a nice long soak. You can also add essential oils to the mix for enhanced relaxation. Your feet will thank you, your body will thank you, and you’ll emerge from that bath a happier person.
2. Massage the area
Massaging the painful area increases blood flow and moves the fluids that accumulate and cause the swelling. If you want to indulge, get someone to massage your feet for you, preferably with hot essential oils.
3. Stop smoking
If you smoke tobacco (cigarettes, cigars, etc.), you should know that one of the many negative effects of nicotine is constriction of blood vessels, which can lead to sore feet.
4. Stay hydrated
When the caffeine and sodium we consume accumulate in the body, they can cause swelling and pain in the limbs. The best way to dilute them and flush them out is by drinking water. If you want to maximize the efficiency of hydration, squeeze a lemon or lime into the glass of water for a boost of vitamins and antioxidants.
5. Eat healthy, avoid excess salt
While we need salt for our body to function well, when we overdo it, it can have adverse effects. Reduce the amount of salt you consume every day, and consider cutting down on caffeine as well.
6. Elevate the legs
If you’re suffering from chronically sore legs/feet, try keep your legs elevated for 30 minutes, three times a day. You will notice a difference within a couple of days. Also, when you’re in bed, use a couple of pillows to prop up your feet. Elevating the legs helps to drain the excess fluids that causes the swelling and pain.
7. Avoid sitting for prolonged periods
Whether you’re flying, taking the bus, or just sitting in an office all day, keeping your legs stationary can lead to pain and swelling. If you know you’re going to sit for a long period of time, make sure to stand up, stretch, and walk around every 20 minutes or so.
8. Use compression socks when traveling
If you’re going to fly overseas, another excellent solution is to use compression socks. These socks apply pressure to your feet, preventing fluid from building up – the main cause of swelling and pain in the feet.
Exercise will help boost your cardiovascular system, which in turn will reduce the possibility of swelling in the limbs. Exercise increases blood-flow in the body and reduces weight.
10. Take magnesium supplements
Magnesium is essential for our body’s function. That said, many people suffer from a magnesium deficiency. By adding magnesium to your system, you will improve your overall health, reduce hangover symptoms and suffer less pain in your extremities
What is ECMO?
Like dialysis for unfunctional kidney, Ecmo for unfunctional lung.
Ecmo stands for extracorporeal membrane oxygenation. It is a method of giving oxygen for the body when icu pateint lungs and/or heart are not able to supply oxygen on their own.
Why ICU pateint put on ECMO?
Doctors place ICU patients on ECMO when patients are not able to supply oxygen to the body.
When a patient’s lungs fail, he/she first is intubated (breathing tube) and hooked up to a ventilator (breathing machine).
However, sometimes lungs are so damaged that providing oxygen through intubation is not enough.
This is when doctors turn to v-v ecmo.
A heart can fail for many reasons including heart attack, pulmonary embolism, bad valve disease, or worsening heart failure. When a heart fails, doctors try to fix the underlying problem. They may also start medications (called ionotropes) to help improve the pump function of the heart. If medications are not enough, doctors will turn to v-a ecmo.
How long can someone stay on ecmo?
That is a complicated question. Due to the risks of ecmo discussed above, doctors try to keep patients on ecmo for as short a time as possible. Often patient will be on ecmo for several days up to 1-2 weeks. Every day, several blood and imaging tests are done to determine if a patient is ready to come off ecmo. As the technology of ecmo improves, hopefully side effects will decrease and patients can remain on ecmo for longer periods of time.
What is the difference between ecmo and a ventilator (breathing machine)?
Both ecmo and a ventilator aim to provide oxygen to the body when the patient’s own lungs and breathing are failing. The ventilator assists the patient’s own lungs by pushing oxygen with pressure into the lungs. Ecmo instead provides oxygen directly via a catheter placed in a patient’s vein or artery. We almost always try oxygenating a patient with a ventilator first. However, when a patient’s lungs are too sick for this, we turn to ecmo to assist in providing oxygen to the body. V-v ecmo provides oxygen through a vein. This blood then has to travel to the heart and be pumped around the rest of the body through arteries. Therefore, with v-v ecmo or with a ventilator, a patient must have a well-functioning heart to get the oxygen pumped throughout the body. V-a ecmo has the additional advantage of pumping blood directly to arteries. This “by-passes” the heart and is therefore the method of ecmo we use when a patient’s heart is failing.
Breast cancer begins when cells in the breast start to get out of control. These cells are mostly in the form of a tumor that can be regularly seen on an x-ray or felt as a lump. The tumor is dangerous (malignant) if the cells attack the surrounding tissues or spread to far off zones in the body. Breast cancer happens mostly in women, yet men can get it, as well.
This is how breast cancer can spread:
- Bosom cancer can spread through the lymph framework
- The lymph framework includes lymph nodes, lymph vessels, and lymph liquid found all throughout the body
- Lymph nodes are little, bean-shaped accumulations of immune system cells that are connected by lymph (or lymphatic) vessels. Lymph vessels resemble little veins, with the exception of that they transport a liquid called lymph (rather than blood) far from the breast
- Lymph contains tissue liquid, waste items, and immune system cells. Breast cancer cells can enter lymph vessels and start to develop into lymph nodes
A large portion of the lymph vessels of the breast deplete into the:
- Lymph nodes under the arm (axillary hubs)
- Lymph nodes around the neck bone (supraclavicular and infraclavicular lymph hubs)
- Lymph nodes inside the neck close to the breast bone (inner mammary lymph hubs)
Following are some of the causes of breast cancer:
- Hormones play a part in creating breast cancer disease; however exactly how this happens is not completely known
- Ordinary breast cells get to be distinctly carcinogenic in view of changes (transformations) in DNA
- Yet, most DNA changes identified with breast cancer are gained in breast cells during a woman’s life as opposed to having been acquired
- Qualities that accelerate cell division are called oncogenes
- Tumor silencer qualities are typical qualities that back off cell division, repair DNA oversights, or advise cells when to bite the dust
- Certain acquired DNA transformations (changes) can drastically increase chances for building up specific growths and are in charge of a large number of tumors that keep running in few families
Some of the treatments of breast cancer include:
- Health alterations: Body weight, physical action, and eating routine are all connected to breast tumor, so these may be territories where you can make a move.
- Restorative alternatives for women at expanded hazard: For women who have certain hazard components for breast growth, for example, a family history; various restorative alternatives may counteract breast cancer.
- Medications to lessen hazard: For women at expanded danger of breast cancer, medications, for example, tamoxifen and raloxifene, can reduce the hazard. However, these medications can have their own dangers and symptoms.
- Preventive surgery: In case that you have a solid family history of breast cancer, you can talk with your specialist about hereditary testing. This test addresses changes in qualities that increase the danger of breast cancer; for example, the BRCA qualities. In case you have a hereditary change from a family with a transformation, however, have not been tried, you could consider surgery to bring down your danger of tumor.
In case you have a concern or query you can always consult an expert & get answers to your questions!
My mother is 70 years old. As per MRI report, her spinal canal dimensions at intervertebral disc level for L4-5 is 0.14 (cross sectional area). Is surgery needed. Please let me know what further information is needed.
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 Disc
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 disc 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 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.
Surgery for herniated disc is recommended only after options like pain relievers, exercise and non-steroid anti-inflammatory drugs do not work. If the pain persists even after these options, then, needs to be removed as steroid injections is not advisable per se.
Activities like bending sideways, pushing, twisting, repetitive lifting can increase the risk of a herniated disc. At times, emergency surgery is also required to avoid paralysis in a patient. In case you have a concern or query you can always consult an expert & get answers to your questions!
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.
