Radiotherapy Cost in Chennai

Cancer remains one of the most significant health challenges worldwide, but modern medical advancements have greatly improved treatment outcomes. Among these advancements, radiation therapy stands out as a cornerstone in cancer care, playing a crucial role in combating various types of cancer. For millions of patients, radiation therapy offers a powerful means to target and destroy cancer cells. This guide will delve into what radiation therapy is, its types, benefits, risks, and its cost in Chennai—a city renowned for its cutting-edge cancer care facilities.

Understanding Radiation Therapy

Radiation therapy, or radiotherapy, uses high-energy particles or waves, such as X-rays, gamma rays, electron beams, or protons, to damage or destroy cancer cells. It works by targeting the DNA within cancer cells, preventing them from multiplying and leading to their eventual death. Unlike systemic treatments like chemotherapy, radiation therapy is localized, focusing on specific areas of the body affected by cancer.

How Radiation Therapy Targets Cancer Cells

Cancer cells grow and divide rapidly. Radiation therapy disrupts this process by damaging the DNA inside these cells. Once their DNA is compromised, cancer cells lose their ability to reproduce and eventually die. While healthy cells in the treatment area can also be affected, they have a better capacity to repair themselves, which minimizes long-term damage.

When is Radiation Therapy Recommended?

Radiation therapy can be employed in different stages of cancer treatment, depending on the type of cancer, its stage, and the patient's overall health. It may be used in the following scenarios:

Curative Treatment: Radiation aims to eliminate tumors and destroy cancer cells, offering a potential cure for early-stage cancers. Adjuvant Therapy: Administered after surgery or chemotherapy, this therapy helps eliminate any remaining cancer cells, reducing the risk of recurrence. Neoadjuvant Therapy: Given before surgery, this approach helps shrink tumors, making them easier to remove surgically. Palliative Treatment: For advanced cancers, radiation helps relieve symptoms like pain, bleeding, or difficulty swallowing, improving the patient's quality of life.

Types of Radiation Therapy

Radiation therapy comes in several forms, each tailored to specific cancer types and locations:

1. External Beam Radiation Therapy (EBRT)

The most common form of radiotherapy, EBRT uses a machine to deliver high-energy beams from outside the body. Treatments are typically spread over several weeks, with daily sessions that last a few minutes each. This method is widely used for cancers of the breast, lung, and prostate.

2. Internal Radiation Therapy (Brachytherapy)

In brachytherapy, radioactive materials are placed directly inside or near the tumor. This method is particularly effective for cancers such as prostate, cervical, and breast cancer. It allows for high doses of radiation to be delivered to the tumor while sparing surrounding healthy tissues.

3. Stereotactic Body Radiation Therapy (SBRT)

SBRT delivers highly focused radiation beams to a small, localized area. It involves fewer treatment sessions with higher doses, making it an efficient option for small, well-defined tumors, particularly in the lungs or liver.

4. Proton Therapy

Proton therapy is a cutting-edge technique that uses protons instead of X-rays. It allows for more precise targeting of tumors, minimizing radiation exposure to surrounding healthy tissue. While effective for certain cancers, proton therapy is less commonly available and tends to be more expensive than traditional radiation methods.
