The radiation is aimed at the right spot from different sides.
It's much like laser beams aimed at one spot, but with radiation instead of light.
One beam isn't as harmful, but at the point where the beams meet the radiation level is a lot higher.

Explain why blood treated with ionising radiation does not expose the patient with ionising radiation?
This is not a routine practice, but it is desirable when transfusing animmunocompromised patient, as the T-lymphocytes in the transfused blood may otherwise provoke a graft-versus-host reaction. Low-dose ionising radiation inactivates the T-lymphocytes without harming the other blood components. Radiation has also been proposed as a method of sterilising the blood units, but much higher doses, which are not necessarily well tolerated by the blood cells, are needed for this purpose.

What overall impact does radiation therapy have on liver cancer patients?
Radiation therapy can have a significant impact on liver cancer patients, depending on various factors, including the stage of cancer, overall health, and treatment goals. Here are key considerations: Tumour Shrinkage: Radiation therapy aims to shrink or destroy cancer cells. In liver cancer, it may be used to target and reduce the size of tumours. This can alleviate symptoms, improve quality of life, and, in some cases, make surgery or transplantation more feasible. Palliative Care: For patients with advanced liver cancer, radiation therapy can be used as part of palliative care. It may help manage symptoms such as pain, bleeding, or discomfort, enhancing the patient's overall well-being. Locoregional Therapy: Radiation therapy is often utilized as a locoregional therapy, meaning it targets cancer cells in the specific region of the liver without affecting the entire body. This can be particularly beneficial in cases where surgery is not an option. Combination Therapies: Radiation therapy may be combined with other treatments, such as surgery, chemotherapy, or targeted therapies, to create a comprehensive and individualized approach to cancer treatment. This combination can enhance the overall effectiveness of the treatment plan. Side Effects: While radiation therapy targets cancer cells, it can also affect nearby healthy tissues. Side effects may include fatigue, nausea, and changes in liver function. The severity of side effects varies among individuals. Improving Candidacy for Transplant: In some cases, radiation therapy may be employed to downsize tumors and improve a patient's eligibility for liver transplantation, providing a potentially curative option. It's crucial to emphasize that the impact of radiation therapy varies for each patient, and treatment decisions should be made in consultation with a multidisciplinary healthcare team. The overall goal is to tailor the treatment plan to the individual's specific circumstances, aiming for the best possible outcome while managing potential side effects.
