What are the 3 types of radiation treatment?

Radiation therapy, also known as radiotherapy, is a medical treatment that uses high-energy radiation to target and destroy cancer cells. Radiation therapy can be categorized into three primary types: External Beam Radiation Therapy (EBRT): In EBRT, a machine called a linear accelerator directs high-energy X-rays or other types of radiation (such as protons) from outside the body toward the tumor. The patient typically undergoes daily treatments over the course of several weeks, with each treatment session lasting only a few minutes. The radiation is carefully calculated and aimed to maximize its effect on the tumor while minimizing damage to surrounding healthy tissue. Internal Radiation Therapy (Brachytherapy): Brachytherapy involves the placement of a radioactive source directly inside or very close to the tumor. This allows for the delivery of a high dose of radiation to the tumor while sparing nearby healthy tissues. Brachytherapy can be used in various forms, such as intracavitary (within body cavities like the uterus or esophagus), interstitial (within tissues), or surface applications. Systemic Radiation Therapy: Systemic radiation therapy involves the use of radioactive substances that can be taken orally or intravenously. These radioactive drugs, also known as radiopharmaceuticals, are absorbed by cancer cells throughout the body. This treatment is primarily used for certain types of metastatic cancers, where cancer has spread to multiple locations in the body.

What is the success rate of radiation therapy?

The success rate of radiation therapy varies widely depending on several factors, including the type and stage of cancer, the location of the tumor, the overall health of the patient, and the effectiveness of the radiation treatment plan. It’s important to note that success in radiation therapy is typically measured in terms of its ability to achieve specific treatment goals, which may include: Cure: In some cases, radiation therapy can be curative, meaning it completely eliminates the cancer. The success rate in achieving a cure depends on the type of cancer and its stage at the time of diagnosis. Certain early-stage cancers, such as some skin cancers and early-stage prostate cancer, can have high cure rates with radiation therapy. Local Control: Radiation therapy is often used to control or shrink tumors, even if a complete cure is not possible. Success in this context means preventing the tumor from growing or causing symptoms. The success rate for local control can vary widely depending on the cancer type and stage but is generally high for many cancers. Palliation: In cases where cancer is advanced and a cure is not feasible, radiation therapy can be used to relieve symptoms, such as pain, bleeding, or obstruction. Success in palliative radiation therapy means improving the patient’s quality of life and providing relief from cancer-related symptoms. Adjuvant or Neoadjuvant Therapy: Radiation therapy is sometimes used in combination with surgery or other treatments. Success in this context means enhancing the effectiveness of other treatments and improving overall outcomes.

Is radiation treatment painful?

Radiation treatment itself is generally not painful. During a radiation therapy session, the patient typically lies still on a treatment table, and the radiation machine is carefully calibrated to target the cancerous cells while minimizing exposure to healthy surrounding tissues. However, there are some potential side effects associated with radiation therapy, and these side effects can vary depending on several factors, including the type and location of the cancer, the dose of radiation, the duration of treatment, and the individual’s sensitivity to radiation. Here are some typical side effects that can occur as a result of radiation therapy: Fatigue: Many patients experience fatigue during and after a course of radiation therapy. This fatigue can range from mild to severe and may be cumulative over the course of treatment. Skin Changes: Radiation can cause skin reactions in the treatment area, such as redness, itching, and peeling. In some cases, the skin may become more sensitive or tender. Hair Loss: If the radiation is targeted at an area with hair, such as the head or face, temporary hair loss in the treatment area may occur. Swelling: Radiation therapy can cause localized swelling, especially if it’s used near or on a limb. Nausea and Digestive Issues: Depending on the location of the radiation treatment, some patients may experience nausea, vomiting, or digestive discomfort. Changes in Appetite: Radiation to the head and neck area can affect a person’s ability to swallow or taste food, potentially leading to changes in appetite. Long-Term Effects: In some cases, radiation therapy may result in long-term side effects, such as changes in the function of the treated organ or an increased risk of developing other health issues in the future.

What is Radiation Therapy?

Radiotherapy or radiation therapy is a crucial medical treatment used in the management of various diseases, primarily cancer. This therapy employs high-energy radiation to target and destroy cancer cells or to shrink tumors.

Why is Radiation Therapy Done?

Radiation therapy is performed for several reasons. Radiation therapy in Chennai is done for the following purposes:

1. Cancer Treatment: The primary goal of radiation therapy is to treat cancer. It can be used as the sole treatment method or in combination with surgery, chemotherapy, or immunotherapy, depending on the type and stage of cancer. Radiation therapy is often chosen when cancer is localized or when surgery is not an option.

2. Tumor Shrinkage: Radiation therapy can be used before surgery to shrink tumors, making them easier to remove. This is known as neoadjuvant therapy.

3. Palliative Care: In cases where cancer cannot be completely cured, radiation therapy can provide palliative care. It helps alleviate symptoms and improve the quality of life by reducing tumor size and relieving pain and discomfort at an affordable radiation therapy cost in Chennai.

4. Adjuvant Therapy: After surgery to remove a tumor, radiation therapy may be administered to destroy any remaining cancer cells and reduce the risk of cancer recurrence.

Procedure of Radiation Therapy

The process involved for radiation therapy in Chennai typically involves several steps including:

Consultation and Planning

The process begins with a consultation with a radiation oncologist, who specializes in radiation therapy. During the radiation therapy in Chennai, an oncologist reviews the patient’s medical history, conducts physical examinations, and assesses diagnostic imaging such as CT scans and MRI. A treatment plan is then developed based on the cancer type, stage, location, and the patient’s overall health.

Simulation

During simulation, the patient is positioned precisely on the treatment table to ensure accurate targeting of the tumor. Immobilization devices like molds or masks may be used to keep the patient in the same position for each treatment session. Imaging techniques such as CT or MRI scans are performed at a reasonable radiation therapy cost in Chennai to map the tumor’s exact location.

Treatment Planning

Using the simulation data, the radiation oncology team calculates the optimal radiation dose and treatment angles to maximize the dose to the tumor while sparing surrounding healthy tissue. Advanced computer software is employed to design the treatment plan.

Radiation Delivery

Radiation therapy in Chennai can be delivered in various ways, including external beam radiation and internal radiation (brachytherapy). External beam radiation is the most common method, involving a machine called a linear accelerator that directs radiation beams at the tumor from various angles.
