Radiation exposure from X-rays is generally considered a lower risk compared to isotope therapy because of the differences in radiation dose, delivery method, and biological impact. X-rays used in medical imaging involve relatively low doses of ionizing radiation that pass…

**Internal radiation therapy** and **external beam radiation therapy** are two main approaches to delivering radiation to treat cancer, and they differ primarily in how and where the radiation is applied to the body. **External beam radiation therapy (EBRT)** involves directing…

Radioactive isotopes do not generally accumulate permanently in the body; instead, their presence and effects depend on the specific isotope’s chemical behavior, biological processing, and radioactive decay characteristics. When radioactive isotopes enter the body, they may initially concentrate in certain…

The half-life of iodine-131, which is about eight days, plays a crucial role in its effectiveness and safety in cancer treatment, particularly in therapies targeting thyroid cancer and other conditions involving thyroid tissue. This radioactive isotope emits beta particles that…

Isotope therapy, also known as radionuclide or targeted radiotherapy, involves using radioactive substances to treat diseases like cancer. Because it uses radiation, strict safety measures are essential to protect patients, healthcare workers, and the public from unnecessary exposure. First and…

Radioactive iodine treatment, commonly used to manage thyroid conditions such as hyperthyroidism and thyroid cancer, can have effects on fertility, but these effects vary depending on several factors including gender, dosage, and individual health. For men, radioactive iodine therapy may…

Some people develop leukemia after radiation exposure because radiation can damage the DNA in blood-forming cells within the bone marrow, leading to mutations that disrupt normal cell growth and function. This damage can cause the bone marrow to produce abnormal…

The risk of developing a secondary cancer after radiation therapy is real but generally very low, especially with modern treatment techniques. Radiation therapy uses high-energy rays to kill cancer cells, but it can also affect nearby healthy cells. In rare…

Cancer cells tend to die more easily from radiation than normal cells primarily because of their inherent biological differences, especially in how they handle DNA damage and cell cycle regulation. Radiation therapy works by damaging the DNA inside cells, and…

Radioactive isotopes emit ionizing radiation, which can damage DNA in cells. However, this damage does not occur in exactly the same way in all healthy cells because the effects depend on several factors including the type of radiation emitted, the…
