What Does Radiation Do In Cancer Patients?

Radiation therapy is normally recommended for patients who have been diagnosed with cancer. Radiation therapy uses high-energy radiation to shrink or kill cancer cells and tumors. Some of the types of radiation for cancer treatment include the use of x-rays and gamma rays. The radiation can be delivered by a device externally, such as a beam of radiation, or it may come from a radioactive material that’s placed inside the body, close to the cancer cells, known as internal radiation therapy or ‘Brachytherapy.’ A systemic radiation therapy method uses a substance called radioactive iodine that can reach the cancer cells via the bloodstream. Almost half of all cancer patients undergo radiation therapy during the course of their cancer treatment.

How does Radiation Therapy Kill Cancer Cells?

Radiation therapy kills cancerous cells by damaging the molecules that are inside the cells that carry genetic information (DNA) and pass it from one generation to the next when the cells split. Radiation therapy can either damage the DNA of the cells or create charged particles within the cells themselves which in turn, damage the DNA of the cell. Once the DNA of the cancer cells have been damaged beyond repair, the cell is unable to duplicate itself and spread throughout the body. These cancer cells eventually die and are broken down by the body’s natural processes.

Doctors often recommend radiation therapy to patients as a means to either cure the cancerous tumor or prevent the recurrence of the cancer, or both. Radiation therapy is normally used as the single mode of cancer treatment or in combination with other cancer treatment methods. Radiation therapy is also sometimes given with palliative intent, which means it’s not intended to cure the patient of their cancer, but rather, relive the symptoms of the cancer, or reduce the suffering that’s caused by the cancer.


Important Note To Remember

Radiation can’t cure cancer. It may kill cancer, but radiation causes cancer. Therefore it shouldn’t be classified as a cure.


Some examples of Palliative therapy include:

  • Radiation given to shrink a tumor near the esophagus.
  • Radiation given to shrink a tumor that is pressing on the spine or growing within a bone.
  • Radiation given to the brain to shrink tumors formed from cancer cells that have spread to the brain from other parts of the body.

Factors Determining the Type of Radiation Therapy

The type of radiation therapy that’s prescribed for a cancer patient usually depends on a number of factors, including:

  • The type of cancer and its size.
  • The location of the cancerous tumor.
  • The involvement of other types of cancer treatment.
  • How far within the body does the radiation have to travel?
  • How close the cancer is to normal tissues?
  • Other factors include the age and medical history of the patient.

The Down Side of Radiation Therapy

While radiation therapy can help reduce the number of cancer cells within the body of a cancer patient, on the flip side is also leads to possible side effects, and direct effects such as: radiation creates cancer. As well as radiation therapy can damage normal cells in the process, which is a side effect that doctors take into consideration while planning the course of action for giving the patient radiation therapy.


What You Can Possibly Do To Avoid Radiation:

You’re body is designed to be well if you put forth the effort and you must have enough life left in your body to accept the good things you’re putting into it.  If you’re one of the lucky people and you are stage-1 or stage-2 you a lot more options.

Experts recommend the following:


If you are stage-3 or stage-4

It’s highly advised that you don’t try to play your own doctor. You really need a skilled physician that knows how to handle your situation. Check out our amazing stage-4 survival story that inspired this website, and get a recommendation to the best natural cancer clinic on the planet.
