What is used to destroy tumors?

Which isotope is used to destroy tumors?

Figure 1. Radioisotope scan to detect tumors. Technetium-99m is perhaps the most widely used radioisotope in diagnosis and treatment (the “m” stands for metastable). This isotope decays to Tc-99 and a gamma emission of low intensity, making the radiation damage fairly negligible.

How do you kill a tumor?

Cancer kills by growing into key organs, nerves, or blood vessels and interfering with and impairing their function. It can begin in almost any human cell. Usually, new cells form through growth and division. Cells die once they become too old or damaged, and newly formed cells replace them.

What is used to destroy cancer cells?

Radiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells.

How long does it take radiation to shrink a tumor?

For tumors that divide slowly, the mass may shrink over a long, extended period after radiation stops. The median time for a prostate cancer to shrink is about 18 months (some quicker, some slower).

Why is a tumor bad?

Malignant tumors are cancerous. They develop when cells grow uncontrollably. If the cells continue to grow and spread, the disease can become life threatening. Malignant tumors can grow quickly and spread to other parts of the body in a process called metastasis.

What happens if I refuse radiation treatment?

Patients who refuse recommended adjuvant radiation therapy have unacceptably high rates of local recurrence. Omission of radiation for advanced age alone is associated with local recurrence rates comparable to those for younger patients.
