Understanding Radio Therapy

So to begin with, here is what you should know about radiotherapy. It is a medical treatment that uses high doses of radiation to kill cancer cells and shrink tumors. It works by damaging the DNA within cancer cells. What it does is prevent them from growing and dividing. Radiotherapy can be used alone or in combination with other treatments like surgery or chemotherapy.

Now there are two main forms of radiation therapy external beam radiotherapy and internal radiotherapy (brachytherapy). External beam radiotherapy directs radiation at the cancer from outside the body, while brachytherapy involves placing radioactive material inside the body near the cancer cells.

So, radiation therapy is carefully planned and administered to minimize damage to surrounding healthy tissues. Side effects can vary depending on the area treated. This may include fatigue, skin changes, and other localized symptoms.

However, if you want to know more about radiotherapy and if a certain type of cancer requires radiotherapy, we would suggest you reach out to Oncare Cancer.

Types of Radio Therapy Available

Now, you may be wondering what types of radiation therapy are available. Here is a comprehensive list of the types:

External Beam Radiation Therapy (EBRT):
  • Administered from a machine outside the body.
  • Typically given over several weeks in daily sessions.
  • Non-invasive, and patients are not radioactive after treatment.
Internal Radiation Therapy (Brachytherapy):
  • Radioactive material is placed inside or near the tumor.
  • Can be temporary or permanent.
  • Requires special safety precautions during the treatment period.
Systemic Radiation Therapy:
  • Radioactive drugs are taken orally or intravenously.
  • The radioactive substance travels throughout the body, targeting cancer cells.
  • Patients may need to follow safety guidelines for a period after treatment.

How does radiation therapy work?

So here is how radiation therapy is supposed to work.

Mechanism of Action

So, radiation therapy treatment works by damaging the DNA within cancer cells. This makes it impossible for them to grow and divide. The treatment is delivered in a way that maximizes the dose to the cancer cells. It also minimises exposure to surrounding healthy tissues.

External Beam Radiotherapy Process

In external beam radiation therapy, machines like linear accelerators generate high-energy x-rays or particles. They are then precisely aimed at the tumor. This precision is achieved using imaging techniques like CT, MRI, or PET scans. They map the exact location and shape of the tumor.

Internal Radiotherapy Process

Internal radiation therapy treatment, or brachytherapy, involves placing radioactive materials directly inside or near the tumor. This provides a high radiation dose to the cancer cells while sparing nearby healthy tissues.

Treatment Schedule and Side Effects

Radiotherapy is usually given over several weeks in daily sessions. This allows healthy cells time to recover between treatments. Side effects vary depending on the treatment area but can include skin irritation, fatigue, and localized effects. For instance, there may be difficulty swallowing or changes in bowel habits. Despite these side effects, radiotherapy is a highly effective treatment for many types of cancer. It has significantly improved survival rates and quality of life for patients.

Conclusion

To sum it up, radiation therapy treatment is one of the best treatments in the fight against cancer. By eradicating cells and preventing it from spreading further, it is making waves in its treatment. However, it is best to consult your doctor who would guide you whether one needs radio therapy or not. With support and hope and successful treatment, it is indeed possible to defeat Cancer.

At Oncare Cancer, you can work with reputed doctors and qualified professionals who will guide you on the path to recovery. It would be wise to reach out to us if you think radiotherapy would be beneficial for your treatment. Our doctors can help you determine the best course for your treatment.
