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.

Arguably one of the most fatal diseases that threaten human life, Meningitis has been the cause of a lot of recent deaths. Essentially Meningitis is triggered off by the anomalous inflammation of the protective membranes called meninges in the brain and spinal cord. Spurred by some sort of a bacterial or viral attack, this condition emanates from an infection of the fluids in the cranial chamber. Often such conditions are also stimulated by some external injury, cancerous development or even certain kinds of reaction from a given drug or the other. 

Depending on the precise cause of the disease, Meningitis may be categorized as Bacterial Meningitis, Viral Meningitis or Fungal Meningitis. Other forms of Meningitis include parasitic Meningitis, Amebic Meningitis and Non-Infectious Meningitis. Meningitis could potentially be contagious. Through lengthy and proximal contact like coughing or kissing, if saliva or spit gets exchanged, Meningitis causing germs may spread from one person to the other.

Bacterial Meningitis
Streptococcus pneumoniae and Neisseria Meningitidis are the two of the most rampant Meningitis causing bacteria. They have the potential of causing irreversible damage to several vital organs. However, with substantive progress in medical science, effective and suitable medication has been made available to the larger populace. But, immediate attention is imperative in this case.

Viral Meningitis
Viral Meningitis is relatively milder than the other forms of meningitis. Enteroviruses, arboviruses and herpes virus are some of the most common sources of this kind of Meningitis. People with strong immunity are usually able to overcome this without much ado. Vaccines are available widely in the markets to cure viral meningitis.

Fungal Meningitis
Fungal Meningitis are caused primarily from external influences. Inhaling fungal spores from the environment is one of the most prominent factors that lead to Meningitis. People suffering from fatal diseases like cancer, diabetes or HIV are more susceptible to fungal Meningitis. While these are a few of the primary forms of meningitis, other triggers to this disease occur due to various environmental interventions. These are consequent upon interactions with various disease causing allergens. Cure to meningitis is available in the form of intravenous injections. But timely diagnosis and treatment is essential for a good outcome. If you wish to discuss about any specific problem, you can consult a pediatrician.

It is very common for women to have heavy and painful periods or have a feeling of fullness in the lower abdomen. Although, it may not sound very alarming these could be the symptoms of uterine fibroids. These are the most common types of benign tumours found in women. The fibroids are basically some tissues and muscle cells that grow within the uterus, outside the uterus, or along the wall of the uterus. The fibroids are usually benign and asymptomatic and do not require any treatment unless they cause problems. 

Know the causes 

Though the exact cause of fibroid formation is not known, it is believed that the female hormones estrogen and progesterone have a role to play in their formation. Fibroids are formed only when a woman is producing these hormones and they are not seen in women in non-reproductive age i.e. before starting of menses or after stoppage of menses (menopause). If fibroids are persisting even after menopause or especially if increasing in size then it is an alarming sign. Such a fibroid needs to be taken care of immediately. 

What are the symptoms? 

Fibroids often remain quiet for long periods of time. They cause nonspecific symptoms in the pelvis and abdomen including: 

1. Fullness in the abdomen 
2. Low back pain 
3. Irregular menstruation 
4. Cramping with menstruation 
5. Painful sex 
6. Increased urgency to urinate 
7. Anemia, leading to tiredness and weakness 
8. Infertility Diagnosing the fibroids 

When these symptoms are recurrent, it is good to confirm the diagnosis. This can happen with a pelvic exam followed by ultrasound scanning to confirm the size and location of the fibroids. A blood test also may be done to confirm anemia, which is common due to heavy periods.

Treatment Options 

Management of fibroids can range from doing nothing to periodic monitoring to surgical removal. 

1. If pain and heavy bleeding are the only symptoms, then pain killers like ibuprofen should suffice for symptomatic relief. Anemia, if severe, may require iron supplementation. 
2. Embolization is an option which shrinks the fibroid, at the same time preserving the uterus. The blood flow to the fibroid is cut off, thereby preventing its further growth. It takes about 1 to 3 hours and requires some bed rest after the procedure. There could be some pelvic pain and vaginal bleeding, which will gradually subside. The fibroids may grow back, but the benefits of keeping the uterus are definitely there. This is suitable in case of single fibroid with specific blood supply. 
3. The next surgical option is myomectomy, where the portion of the uterus which contains the fibroid alone is removed. This is done in women who still wish to get pregnant and in women who would like to retain the uterus. This can also be achieved laparoscopically( key hole surgery). In such cases, fibroids are cut into small pieces and then removed from the body. This procedure should be done by a doctor specialised in advanced gynecological endoscopy as all this cutting should be done in a bag to avoid any spillage of cells inside the abdominal cavity. This procedure is known as Laparoscopic Myomectomy with In-bag Moecellation. 
4. In women who have crossed their pregnancy phase, hysterectomy or complete removal of the uterus is advised. In these women, the bleeding and pain may not have subsided even after years of treatment with hormones. The growing fibroids could be pressing on the adjacent organs, causing pressure. This is the only definitive treatment and should be done in women have completed their family and don’t desire to be pregnant. 
5. Myomectomy and hysterectomy may be done laparoscopically or with an open method depending on the overall health, the size and location of the fibroids in the uterus.

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.

Symptoms:

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

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.
