Radiation Therapy in India

Radiation Therapy (RT) is a medical approach that involves utilizing ionizing radiations or radioactive materials to treat malignant (rapidly spreading to whole body) cancers. It can also be considered for treating certain benign (localized a part of body) conditions occasionally. 

While the interaction between radiation and tissue yields various effects, the primary mechanism of action in radiotherapy is to eliminate cancer cells and impede their multiplying capacity. These outcomes may arise from direct harm to DNA or other crucial cellular components, a phenomenon frequently observed with particulate radiations like alpha particles, protons, or electrons. Alternatively, indirect cellular damage can occur, triggered by the generation of free radicals, as seen with X-rays or Gamma-rays.

Unfortunately, in the course of radiation therapy, there is a risk of damage and loss of normal cells, particularly those undergoing active divisions. However, this issue can be mitigated by precisely directing the radiation beam toward the tumor and by dividing the total radiation dose into fractions, allowing normal tissues to recover and undergo repair.

Why is Radiation Therapy needed?
Radiation Therapy is a comprehensive approach that not only kills cancer cells and reduces tumor size but also alleviates cancer symptoms. It can serve as the primary treatment or be employed strategically in various ways:

• Shrinking Tumors Before Other Treatments: Known as neoadjuvant therapy, radiation therapy can be utilized to reduce tumor size before other cancer treatments, such as surgery.
• Eliminating Residual Cancer Cells After Surgery: As adjuvant therapy, radiotherapy is applied post-surgery to eradicate any remaining cancer cells and enhance treatment effectiveness.
• Targeting Recurrent Cancer Cells: In cases of cancer recurrence after prior treatments, radiotherapy proves effective in eliminating returning cancer cells.
• Relieving Symptoms: When employed for symptom relief, termed palliative treatments, external beam radiation can shrink tumors to manage pain and other issues induced by the tumor, such as breathing difficulties or loss of bowel and bladder control. Furthermore, systemic radiotherapy drugs, known as radiopharmaceuticals, are effective in treating bone pain resulting from cancer spread to the bones.

For internal Radiation Therapy, a physical examination and imaging may be necessary. Your radiation oncologist will provide instructions on preparing for the procedure based on the method of radiation delivery.
In the case of external beam radiation therapy (EBRT), a planning session known as simulation is conducted. Simulation is a crucial step in customizing your treatment and involves:

• Positioning: You are placed on a table exactly as you will be during treatment sessions. Your radiotherapy team may use a mold or mask to secure your body in place, ensuring correct alignment. Temporary or permanent markings (tiny dots) may be applied to indicate the specific body parts that should receive radiation.
• Scans: You undergo a CT scan or an MRI to identify the tumor's location. This information aids your care team in tailoring X-rays that target the tumor while minimizing exposure to healthy tissue.
• Simulation serves as a vital tool for your radiation oncologist to determine the appropriate radiation dosage and delivery method for your specific case.

Following the planning stage, your healthcare team will determine the specific type and dosage of radiation tailored to your individual case. This decision takes into account factors such as the type of cancer you are dealing with, your overall health, and your treatment objectives. The meticulous planning is essential to ensure accuracy in both the dose and targeting of the radiation beams. Precision in this regard minimizes the impact on healthy cells surrounding the cancer, contributing to a more targeted and effective treatment.

You may expect following in external Radiotherapy:

• External beam radiation therapy is done using a machine called a linear accelerator, which directs high-energy beams into your body. 
• As you remain still, the linear accelerator moves around you, delivering radiation from multiple angles. 
• Your care team customizes the machine settings for your specific needs, ensuring precise radiation dosage to the exact point on your body. 
• The experience is akin to receiving an X-ray, and you won't feel the radiation during delivery.
• Typically performed on an outpatient basis, external beam radiation therapy doesn't require hospitalization. 
• Treatment frequency often spans five days a week over several weeks to allow healthy cells time to recover between sessions. 
• Some shorter courses may last 1 to 2 weeks, particularly for relieving symptoms in advanced cancers. 
• Each session, lasting approximately 10 to 30 minutes, involves positioning your body accurately on the table using molds and props established during planning. 
• While the linear accelerator emits a buzzing sound and rotates around your body to access the target from different angles, your radiation therapy team remains nearby, accessible through video and audio connections. 
• Although discomfort during radiation is uncommon, it's important to communicate any concerns to your team.

You may expect following in internal radiotherapy:

• Internal radiation therapy usually happens in a special outpatient treatment room or in a hospital. 
• Your radiation oncologist may insert the radiation implant using a small flexible tube called a catheter. 
• For this treatment, you’ll receive anesthesia so you don’t feel pain or discomfort during the procedure. 
• With the systemic form of internal radiotherapy, you’ll receive radioactive fluid through an IV.

Most individuals undergo radiation therapy across several sessions to avoid receiving the full dose all at once. This spaced-out treatment schedule allows healthy tissues time to recover between sessions, minimizing potential side effects. While your radiation oncologist will assist in managing any unpleasant side effects, it's essential to note that these effects typically impact only the specific part of your body receiving radiation. Possible side effects include:

• Fatigue
• Nausea
• Vomiting
• Diarrhea
• Headache
• Skin Irritation
• Dry And Itchy Scalp
• Hair Loss
• Mouth Sores
• Pain During Swallowing
• Reduced Appetite
• A Burning Sensation In The Throat Or Chest
• Pain Or Burning During Urination
• Frequent Urination In Small Amounts
• Abdominal Bloating Or Cramps
• Sense Of Urgency For Bowel Movements

Occasionally, side effects may emerge post-treatment, referred to as late side effects. In extremely rare cases, new cancers may arise years or even decades after the initial cancer treatment, potentially attributed to radiation or other therapeutic interventions. This phenomenon is known as a second primary cancer. To understand what side effects you may suffer, consult with your radiation oncologist, considering the type of radiation therapy recommended for your specific cancer.

Following internal radiation therapy, you typically return home after a brief recovery on the same day. In some instances, there might be a need for a hospital stay while your body eliminates minimal amounts of radiation. For systemic (IV) radiotherapy, you may excrete small amounts of radiation through bodily fluids like sweat, urine, and blood.

If you undergo IV or permanent internal radiation therapy, there is a slight risk of exposing others to radiation. It's essential to adhere to the guidance provided by your therapeutic team regarding the extent of contact you should have with others following radiotherapy.

You should be able to resume your regular daily activities both before and after external beam radiation therapy (EBRT), with no risk of exposing others to radiation.

Following Radiation Therapy, imaging tests may be conducted to assess whether the cancer is undergoing shrinkage. The response to radiotherapy can vary, with some cancers showing immediate improvement, while in other cases, it may take weeks or months to observe the treatment's effectiveness. It's advisable to inquire with your radiotherapy team about the anticipated timeline and outcomes specific to your situation.
Now that your radiation therapy is over, you might be contemplating some health-oriented goals to pursue. Engaging in physical activity, maintaining a nutritious diet, achieving a healthy body weight, and refraining from smoking can contribute to:

• Regaining or Building Strength: Physical activity and a balanced diet can aid in regaining or building strength after the challenges of treatment.
• Reducing Side Effects: A healthy lifestyle may help alleviate lingering side effects from treatment.
• Minimizing the Risk of Second Cancers or Other Health Issues: Adopting healthy habits can contribute to reducing the risk of developing second cancers or other health problems.
• Managing Stress: Engaging in wellness practices can be effective in managing stress, fostering emotional well-being.
• Alleviating Fatigue: Following a wellness plan may assist in reducing fatigue, promoting overall energy levels.
• Enhancing Enjoyment of Life: Embracing a healthy lifestyle can contribute to a more enjoyable and fulfilling life post-treatment.

A personalized wellness plan is a crucial component of your post-treatment care. Tailored to your individual needs, preferences, and fitness level, it will likely differ significantly from that of another survivor. This plan is designed to help you feel better and support your recovery after cancer treatment.

Radiation therapy stands as a pivotal contributor to global cancer cures, accounting for 40% of all successes while significantly enhancing the quality of life for many individuals. Notably, external-beam radiotherapy emerges as a highly successful treatment for prostate cancer, as evidenced by a cure rate of 95.5% for intermediate-risk cases and 91.3% for high-risk cases. The 5-year survival rate of 98.8% underscores the overall efficacy of this approach. Research from the Journal of Medical Imaging and Radiation Oncology in 2015 confirms the superiority of external-beam radiation therapy, with results comparable to or surpassing other common treatments like surgery or brachytherapy. 

In various cancers, including breast, bowel, uterine, skin, and prostate cancer, this therapy proves highly effective in reducing the risk of recurrence when administered before or after surgery. Moreover, for specific cancers such as prostate, head and neck, bladder, lung, cervix, and skin cancers, radiotherapy, either alone or in combination with drug therapy, serves as a primary curative treatment, offering an alternative to surgical risks and organ removal. 

Even in cases where cure is not possible, radiotherapy can be effective in relieving pain and addressing cancer-related issues, such as bleeding. However, technological advancements in recent years have further improved the lives of cancer patients by making radiation treatments quicker, more precise, and highly effective.
