How does beta radiation kill cancer cells?

Beta emission from radioisotopes kills tumor cells but also kills normal cells. As blood circulates through the bone marrow, beta decay from circulating radionuclide conjugates irradiates bone marrow cells producing myelosuppression.

What type of radiation kills cancer?

Radiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. Your cells normally grow and divide to form new cells.

How do radioactive isotopes treat cancer?

Radioisotope therapy is a procedure in which a liquid form of radiation is administered internally through infusion or injection. RIT’s ultimate purpose is to treat cancerous cells with minimal damage to the normal surrounding tissue. These therapies are not normally the first approach used to fight a patient’s cancer.

What happens if I refuse radiation treatment?

Missed Radiation Therapy Sessions Increase Risk of Cancer Recurrence. Patients who miss radiation therapy sessions during cancer treatment have an increased risk of their disease returning, even if they eventually complete their course of radiation treatment, according to a new study.

At what stage of cancer is radiotherapy used?

Radiotherapy may be used in the early stages of cancer or after it has started to spread. It can be used to: try to cure the cancer completely (curative radiotherapy) make other treatments more effective – for example, it can be combined with chemotherapy or used before surgery (neo-adjuvant radiotherapy)

What is the most common acute side effect of radiation treatment?

Early and late effects of radiation therapy

The most common early side effects are fatigue (feeling tired) and skin changes. Other early side effects usually are related to the area being treated, such as hair loss and mouth problems when radiation treatment is given to this area.

Why are cancer cells more susceptible to radiation?

Radiation affects cancer cells by damaging their DNA, so that the cancer cells can no longer divide and grow. Radiation is most effective at killing cells that are actively dividing. Cancer cells are more vulnerable to radiation for two reasons: they divide more rapidly than normal cells.
