Cancer is treated by Radiotherapy. It kills cancer cells and prevents their spread by administering high amounts of radiation. All cancer patients—roughly half—receive it. A doctor may inject radioactive material inside your body, or the radiation may come from external sources like specialised devices. Radiotherapy can harm both healthy and cancerous cells. To minimise adverse effects, treatment must be well thought out. Skin changes and tiredness are frequent adverse effects. Depending on the area of your body being treated, there may be additional adverse effects. Radiation is sometimes combined with other therapies like surgery or chemotherapy. The global annual burden of cancer is anticipated to increase, with more than 19 million new cases and 10 million deaths in 2020 alone. One of the most often employed therapies for the treatment of cancer is radiotherapy. Ionizing radiation, commonly referred to as nuclear radiation, is used in radiotherapy to injure and kill cancerous tumour cells. In this episode, medical professionals discuss the various types of radiation and what it takes to deliver this potentially life-saving treatment. Your response to Radiotherapy is influenced by a variety of variables, such as:
Using radiation to treat cancer is known as radiotherapy. The majority of cancer patients require radiotherapy as part of their overall treatment regimen. It can be used alone or in conjunction with other cancer treatments such endocrine therapy, immunotherapy, surgery, chemotherapy, and chemotherapy. Radiation can be used to treat cancer, lessen the likelihood of cancer returning, or ease cancer-related symptoms. Radiotherapy can be administered from inside the body or from outside (external radiotherapy) (internal radiotherapy). External beam radiation is the most popular type of radiotherapy. An external source of high intensity radiation is directed at the area of the body that is affected by cancer using a machine, and the radiation travels through the body to the cancerous spot. When receiving internal radiation, the radioactive source is positioned inside the patient. This may take the form of radioactive liquids that are absorbed by tumour cells at the site of the tumour or radioactive implants that are positioned in or very near the tumour. Proton therapy, also known as external beam therapy or Intensity Modulated Proton Therapy, uses ionising radiation. Proton accelerators are used in intensity modulated proton therapy to direct a beam of protons at malignancies. When given either before or after surgery, Radiotherapy is very successful in lowering the chance of cancer recurrence for many common cancers, including breast cancer, bowel cancer, uterine cancer, skin cancer, and prostate cancer. Radiotherapy, with or without medication therapy, can be used as the primary curative treatment in various malignancies (prostate, head and neck, bladder, lung, cervix, and skin cancers), avoiding the dangers of surgery and the removal of tissues. Radiotherapy is particularly effective at reducing pain and other side effects of cancer, like bleeding, for some malignancies that are too advanced to be cured. For instance, in around 75% of patients, pain from the spread of cancer to the bones can be considerably reduced or eliminated. Radiotherapy has recently benefited from new technology developments that have made treatments even quicker, more precise, more successful. To guarantee that cancer patients can continue to get top-notch, cutting-edge radiotherapy, ongoing investment in new technology is essential.
