STEREOTACTIC RADIOSURGERY

-

 


A kind of radiation is stereotactic radiosurgery. When this method is conducted on the body rather than the brain, it is known as stereotactic body radiation (SBRT) or stereotactic ablative radiotherapy (SABR).


To treat cancers and other diseases across the body, the treatment employs a large number of carefully targeted radiation beams. SBRT is used to treat cancers that have spread to the lungs, spine, liver, neck, lymph nodes, or other soft tissues.


TYPES OF STEREOTACTIC SURGERY 


  • Linear accelerator (LINAC) equipment treats malignant and noncancerous disorders in the brain and other regions of the body with X-rays (photons). LINAC machines are also known by their manufacturer's brand names, such as CyberKnife and TrueBeam. For bigger tumours, these devices may conduct SRS in a single session or across two to five sessions (fractionated stereotactic radiotherapy).

  • Proton beam (charged particle) therapy is the most recent kind of stereotactic radiation and is only offered in a few research institutes in the United States, while the number of centres delivering proton beam therapy has expanded dramatically in recent years. It can treat body cancers with fractionated stereotactic radiation over numerous sessions. Proton beam SBRT may be utilised to treat malignancies in certain areas of the body.



TREATMENT METHOD 

The specialised equipment directs radiation beams onto a tumour or other target. Each beam has minimal effect on the tissue it passes through, but a concentrated dosage of radiation is given at the point where all of the beams collide. The high dosage of radiation supplied to the afflicted region shrinks tumours and causes blood vessels to seal down over time, depriving the tumour of its blood supply.

Because of the accuracy of stereotactic radiosurgery, there is little harm to healthy surrounding tissues. When compared to other forms of conventional surgery or radiation therapy, radiotherapy has a lower risk of adverse effects in most circumstances.


Doctors specialising in this field can provide intricate guidance on the cases. One should always be aware and look out for symptoms which may seem like nothing at first but can turn to worse, if ignored. 

Mentionable names among some of the Best Oncologists in Kolkata are:

Dr. Sanjoy Roy  and Dr. Sayan Paul.

Arrhythmia surgery

  Arrhythmia surgery is a medical procedure performed to treat irregular heartbeats, also known as arrhythmias. These abnormal heart rhythms can cause symptoms such as fatigue, dizziness, shortness of breath, and even chest pain. If left untreated, they can lead to serious complications, such as stroke or heart failure. Arrhythmia surgery is usually recommended when medication and other non-invasive treatments fail to control the irregular heartbeats. The procedure involves the use of various techniques to destroy or modify the abnormal electrical pathways in the heart. Some of the techniques used in arrhythmia surgery include catheter ablation, maze procedure, and implantable devices such as pacemakers and defibrillators. Catheter ablation is a minimally invasive procedure in which a thin, flexible tube (catheter) is inserted through a vein in the groin and threaded up to the heart. Once in the heart, the catheter is used to deliver energy (such as radiofrequency or cryotherapy)...

CANCER AND MENTAL HEALTH- IT DOESN’T JUST AFFECT YOUR BODY

As far as treatment for cancer goes, with recent technology and advanced methods of treating the disease the procedure has of course become a lot less painful and efficient, decreasing mortality rate by quite a lot as compared to traditional methods of treatment. Doctors now have a better understanding of the causes, symptoms and effects and how to treat their patients accurately. The patients too are always updated and consoled to the best one can, but does it mean that those affected are free of mental and emotional distress? Unfortunately the answer is still a no for this one. Knowing that one has ‘cancer’, irrespective of the sort and the intensity, the word itself has the capability to put a person into deep distress. Feelings of depression, anxiety and fear are very common in such cases. It is a tug of war between life and death and the exhaustion of anticipation is clearly high on a person and their loved ones. No matter how much knowledge and sympathy or compassion one might ge...

Blood Cancer- Part 2

  How is blood cancer diagnosed? A physical examination to check your overall health is often the first step in making a diagnosis. Your doctor will look at your body and lymph nodes, look for signs of infection, and review your medical history. The diagnosis of blood cancer can be made with a variety of tests and procedures. The type of blood cancer that is suspected will dictate what you need. In order to make a diagnosis, your care team may suggest testing and evaluate all of the results with you. Biopsies A biopsy is a procedure that takes cell samples for a pathologist to look at in a lab. A lymph node biopsy, which involves taking a sample of lymph tissue or the entire lymph node, may be required for certain types of blood cancer, such as lymphoma. Certain types of blood cancer can be identified by testing your bone marrow, the place where blood cells are made. A bone marrow aspiration is a method by which a small amount of blood, bone, and bone are taken from either a breast...
