Radiation Oncology
Radiotherapy is the controlled use of high energy X-rays to treat different types of cancer. It is also known as radiation oncology treatment (Cancer Treatment). According to NCI, approximately 60% of the cancer patients receive radiation therapy during treatment and in some cases; radiotherapy is also used to treat benign (non-cancerous) tumours.
Radiation therapy is done with curative intent or palliative intent and usually lasts from one week to 7-8 weeks. The duration depends on stage, histological type, location and intent of treatment. Radiation therapy is a local treatment like surgery. It can be done alone or in combination with other modalities like surgery and/or chemotherapy. It can be implemented to cure tumour, shrink the tumour prior to radical surgery in pre-operational setting and post operation to kill microscopic amounts of leftover tumours and to prevent relapse.
Uses of Radiotherapy
Radiotherapy may be used:
- to cure an illness – for example, by destroying a tumor (abnormal tissue)
- to control symptoms – for example, to relieve pain
- before surgery – to shrink a tumor to make it easier to remove
- after surgery – to destroy small amounts of leftover tumor and to prevent relapse
Courses of Radiation
Radiotherapy is usually given as a course of treatment that lasts for a number of days or weeks. Most people who undergo radiotherapy to treat a serious condition, such as cancer, have five treatments a week (one treatment a day, Monday to Friday) with a break at the weekend. Taking a break allows the normal and non-cancerous cells to recover. Depending on cases, a patient can get radiation treatment more than once a day or over the weekend.
Patients suffering from cancer and certain non malignant condition require radiation therapy. Asian Institute of Medical Sciences is the first hospital in North India to deploy the innovative RapidArc TM. The Radiology department at Asian Hospital has state-of-the-art radiotherapy facility with facilities for both internal and external radiation therapy.
