Radiotherapy, also known as radiation therapy, is a type of cancer therapeutic, which uses high-energy radiation for treatments. The radiation can come from a machine outside the body (external beam radiotherapy) or from a radioactive source placed inside the body near the cancer cells (brachytherapy). Radiotherapy can be used alone or in combination with other cancer treatments, such as surgery and chemotherapy. Cancer is a disease that has claimed many lives worldwide. Despite medical advancements, it remains a significant threat to human life. However, the use of radiation therapy or radiotherapy has significantly improved cancer treatment. Radiotherapy uses high-energy radiation to kill cancer cells and shrink tumors. Radiotherapy works by attacking the DNA inside cancer cells, making it difficult for them to divide and grow. Healthy cells can also be affected by radiation, but they are usually better able to repair the damage than cancer cells. The goal of radiotherapy is to kill as many cancer cells as possible while minimizing damage to healthy cells. External beam radiotherapy (EBRT) is the most common type of radiotherapy. It involves the use of a machine called a linear accelerator to deliver high-energy radiation beams to the cancerous area. The radiation beams are carefully aimed at the cancerous area to avoid damaging nearby healthy tissue. Brachytherapy, also known as internal radiotherapy, involves the insertion of a radioactive source directly into or near the cancerous area. The radiation source can be temporary or permanent. The radiation from the source is delivered directly to the cancer cells, minimizing damage to nearby healthy tissue. Stereotactic Body Radiotherapy (SBRT) is a highly precise form of radiotherapy that uses advanced imaging techniques to deliver high doses of radiation to a specific area of the body. It is commonly used to treat small, early-stage tumors in the lung, liver, and prostate. Proton therapy is a type of external beam radiotherapy that uses protons instead of photons to deliver radiation to the cancerous area. Protons are able to deliver a higher dose of radiation to the tumor while minimizing damage to surrounding healthy tissue. Radiotherapy is used to treat a wide variety of cancers. Radiotherapy is commonly used in the treatment of breast cancer. It is often used after surgery to kill any remaining cancer cells and reduce the risk of recurrence. It can be used alone or in combination with other cancer treatments to treat lung cancer. It is commonly used to treat small, early-stage tumors. Radiotherapy is commonly used in the treatment of prostate cancer. It can be used alone or in combination with other cancer treatments, such as hormone therapy. It is often used in the treatment of head and neck cancer. It can be used alone or in combination with other cancer treatments, such as surgery and chemotherapy. Radiotherapy is commonly used in the treatment of gynecologic cancers, such as cervical and endometrial cancer. It can be used alone or in combination with other cancer treatments. Like all cancer treatments, radiotherapy can cause side effects. The side effects of radiotherapy depend on the type and location of the cancer being treated, as well as the radiation dose and the patient's overall health. Common side effects of Radiotherapy include, fatigue is a common side effect of radiotherapy, especially during the later weeks of treatment. The fatigue can range from mild to severe and can affect daily activities. Radiotherapy can cause skin changes, such as redness, itching, dryness, and peeling, in the area being treated. The severity of the skin changes depends on the radiation dose and the location of the cancer. Radiotherapy to the abdomen or pelvis can cause nausea and vomiting. Medications can help relieve these symptoms. Radiotherapy to the head can cause hair loss in the treated area. Radiotherapy to the arms or legs can cause swelling, called lymphedema. This swelling can be managed with compression garments and exercise. Long-term side effects of radiotherapy are rare, but they can occur. These side effects can include secondary cancers, damage to organs and tissues in the treated area, and infertility. Get Free Press Release of Radiotherapy Market
