What is Radiation Therapy?

Radiation therapy, also known as radiotherapy, is a treatment method that uses high doses of radiation to kill cancer cells and shrink tumours. It's a common treatment for various types of cancer and can be used alone or in combination with other treatments such as surgery and chemotherapy. Unlike chemotherapy, which affects the whole body, radiation therapy targets specific areas, concentrating on the tumour to minimise damage to surrounding healthy tissue.

How Does Radiation Therapy Work?

Radiation therapy works by damaging the DNA of cancer cells. This damage is mostly caused when radiation creates free radicals within the cells, which in turn lead to cell death. Cancer cells divide more rapidly than most normal cells, making them more susceptible to radiation damage. The therapy is carefully planned to deliver the radiation precisely to the cancer cells while sparing as much healthy tissue as possible.

Types of Radiation Therapy

There are two main types of radiation therapy: external beam radiation therapy and internal radiation therapy, also known as brachytherapy. External beam radiation therapy delivers radiation from outside the body using a machine called a linear accelerator. Brachytherapy involves placing a radioactive source directly into or near the tumour, providing highly targeted radiation doses. The type of radiation therapy chosen depends on the type, location, and stage of the cancer, as well as the patient’s overall health and preferences.

Side Effects of Radiation Therapy

While radiation therapy is designed to minimise damage to healthy tissue, some side effects can occur. These may vary depending on the area being treated and the dose of radiation. Common side effects include fatigue, skin irritation at the treatment site, and changes in sensation or organ function near the treated area. Most side effects are temporary and can be managed with medical support, though some may persist longer term.

The Role of Radiation Therapy in Cancer Treatment

Radiation therapy plays a key role in the treatment of many cancers. It can be used as a primary treatment or as an adjunctive measure to enhance the effectiveness of surgery or chemotherapy. In some cases, it is used palliatively, to relieve symptoms in advanced stages of cancer. Advances in technology continue to improve the precision and effectiveness of radiation therapy, reducing side effects and improving outcomes for patients.

Conclusion

Radiation therapy is a crucial component of cancer treatment strategies in the UK and worldwide. It offers targeted intervention that can effectively manage and treat various forms of cancer, contributing significantly to patient recovery and quality of life. Continuous research and development in this field promise even more precise and less invasive treatment options in the future, giving hope to many facing cancer diagnosis.

What is Radiation Therapy?

Radiation therapy is a treatment for cancer. It uses strong rays to kill cancer cells and make tumors smaller. This treatment is common for many types of cancer. Doctors might use it alone or with surgery and other medicines. Radiation therapy targets only the area with cancer, so it protects healthy parts of the body.

How Does Radiation Therapy Work?

Radiation therapy works by breaking the cancer cells inside the body. It uses radiation to create very small particles that damage the bad cells. Cancer cells grow faster than healthy cells, so they are easier to destroy with radiation. Doctors carefully plan how to use radiation so they can hit the cancer cells and keep healthy parts safe.

Types of Radiation Therapy

There are two main ways to do radiation therapy. One uses a machine that sends radiation from outside the body. This is called external beam radiation. The other way, called brachytherapy, puts radioactive material directly near the cancer. The choice depends on where the cancer is and how much it has spread. It also depends on what the patient prefers and what is best for their health.

Side Effects of Radiation Therapy

Radiation therapy might cause some problems. These problems depend on where the treatment happens and how much radiation is used. Common problems are feeling very tired, skin changes where the treatment is, and changes in how the body feels or works near the area treated. Most problems go away after some time, but doctors can help manage them.

The Role of Radiation Therapy in Cancer Treatment

Radiation therapy is very important in fighting cancer. It can be the main treatment or used with surgery or other medicines to work better. Sometimes, it is used to help people feel better if the cancer is very advanced. New technology makes radiation therapy more precise and effective, causing fewer side effects and helping patients live better.

Conclusion

Radiation therapy is a big part of cancer treatment in the UK and around the world. It helps target and treat different cancers, helping people recover and improve their lives. Scientists keep researching to find even better and safer ways to use radiation therapy, giving hope to those diagnosed with cancer.
