Radiation Therapy
Radiation therapy can be defined as cell-targeted therapy that uses ionizing radiation to destroy cancer cells. This can cause damage to the genetic makeup of the cells, which in turn causes the growth and replication of these cells to stop. This radiation can damage surrounding tissues. Normal cells. But most normal cells can recover from it. Maximizing the destruction of cancer cells is the goal of treatment. Radiation therapy is used to completely destroy or shrink the tumor to relieve symptoms.
Radiation therapy may be used alone or in combination with chemotherapy or surgery. This is mainly to improve the success rate of treatment. In some cases, radiotherapy is used as symptomatic treatment or palliative treatment to relieve symptoms such as pain and improve the patient's condition.

Various Methods Of Radiation Therapy
Basically, there are two types of radiation therapy: external radiation therapy and internal radiation therapy. The effectiveness of external beam radiotherapy can be achieved with some advanced techniques such as three-dimensional symmetric radiotherapy, intensity modulated radiotherapy (IMRT) and proton beam therapy doctor in Delhi (PBRT). Stereotactic radiotherapy is a treatment for brain tumors. It can be delivered in three ways: with a linear accelerator-based tactical 3D beam, the use of highly charged protons or helium ions, and Gamma Knife technology. Brachytherapy is another advanced technique.
Intensity Modulated Radiation therapy (IMRT) - It uses a computer-controlled linear accelerator to deliver a precise dose of radiation to a malignant tumor or a specific area within the tumor. IMRT involves adjusting or controlling the intensity of multiple small-volume beams to more accurately match the radiation dose to the three-dimensional (3D) shape of the tumor.
This allows minimizing the dose to surrounding normal critical structures while higher doses of radiation can be directed to the tumor. Careful treatment planning is performed using patient images via 3D computed tomography (CT) or magnetic resonance imaging (MRI) and computerized dose calculations to determine the optimal dose rate pattern for the tumor shape. Generally, by combining multiple intensity modulation fields from different directions of the beam, an individual radiation dose is generated, maximizing the tumor dose and minimizing the dose to adjacent normal tissue.
Proton Beam Radiation Therapy (PBRT) - In this method, protons are used instead of X-rays to treat cancer.
Protons are positively charged particles. Under high energy, protons can destroy cancer cells. Doctors can use proton therapy alone. They can also combine it with X-ray therapy, surgery, chemotherapy, and/or immunotherapy.
Like X-ray radiation, proton therapy is a form of external beam radiation therapy. The radiation is blasted painlessly through the skin by external devices.

Radiation Therapy Effectiveness
Radiation therapy prolongs the survival of cancer patients. As with all treatments, different cells respond differently to this treatment. Radiation sensitivity represents the response of cancer cells. The amount of radiation absorbed by cancer cells is termed as radiation dose. The unit of radiation dose currently used is grays (gy).
Highly sensitive cancer cells such as blood cancers and germ cell cancers are quickly destroyed by a small amount of radiation. Moderately sensitive cells such as skin cancer cells require higher doses of radiation. There are also radiation-resistant cells such as renal cell carcinoma and melanoma examples. In this case, a higher radiation dose is the first choice. The cure density of tumors varies. Leukemia cannot be cured because cancer cells can spread throughout the body. If the lymphoma is concentrated in a specific area, it can be treated. Tumors that are sensitive to radiation are usually treated with a curative dose of radiation therapy.
Size is also a important factor in deciding cancer treatment. Small tumors are more sensitive than large tumors. Various methods are used to eliminate this effect. Surgical resection before treatment is a common practice. Breast cancer is often treated with it. Another option is neoadjuvant chemotherapy before definitive radiotherapy. Cetuximab, cisplatin, and other drugs can be used before radiation therapy. These are all radiosensitizers.
Cancer treatment is a complex process and in order to receive best treatment one should consult with the best oncologist in Delhi NCR. It helps patient in receiving the correct treatment and help through the treatment process. That's why Dr. Dodul Mondal will be a very good choice due to his expertise on working with Proton Beam Therapy.
