What is Radiation.

Radiation is one of cancer’s most common therapies. radiation therapy,  radiation therapy, irradiation, or x-ray therapy are other names  for radiation treatment.

Radiation therapy uses high energy waves to treat cancer to kill tumor  cells, the objective is to  destroy or damage the cancer without damaging  too  many healthy cells.

All the time, background radiation is around us, most of it is formed of minerals, of course, these minerals are radioactive in the soil, water,  and even our bodies.

The radiation from the background can also come from outside space  and the sun, other sources, such as x-rays, cancer radiation therapy, and  electrical power  lines, are man-made.

Radiation.

The term “radiation therapy” mostly refers to radiation therapy with  external beams. During this radiation type,High-energy beams  come from a machine outside your body that focuses the beams on  your body at a precise point. 

Radiation is placed inside your body during a different type of radiation  therapy called brachytherapy (brak-e-THER-uh-pee).

How radiation therapy is used in people with cancer.

Your doctor may suggest radiation therapy for various reasons during  your cancer treatment, including:

  • The only (primary) cancer treatment.
  • In advanced cancer to alleviate cancer symptoms.
  • Shrinkage of a cancerous tumor (neoadjuvant therapy) before surgery.
  • Stopping the growth of any remaining cancer cells after surgery (adjuvant therapy).
  • The destruction of cancer cells in combination with other treatments, such as chemotherapy.

Causes.

Radiation is the energy released as a wave or as a small particle of matter  from atoms. 

Radiation sickness is caused by high radiation dose exposure,  such as high radiation dose received during an industrial accident.

Symptoms.

The severity of radiation sickness signs and symptoms depends on how  much radiation you have absorbed, how much you absorb depends on the  radiated energy strength, the time of your exposure, and the distance  between you and the radiation source.

The type of exposure, such as total or partial body, also affects signs and  symptoms. It also depends on how sensitive the affected tissue is to the  severity of radiation sickness, gastrointestinal system and bone marrow,  for example, are highly radiation sensitive.

Possible symptoms include:

  • Diarrhea.
  • Fever.
  • Hair loss.
  • Infections.
  • Dizziness.
  • Disorientation.
  • Weakness.
  • Fatigue.
  • Low blood pressure.
  • Nausea and vomiting.

Types of Radiation Therapy.

There are two main radiation therapy types, external and internal beams.

Many factors depend on the type of radiation therapy you may have,  including:

  • The type of cancer.
  • The size of the tumor.
  • The tumor’s location in the body.
  • Your general health and history of medicine.
  • Other factors like your age and other medical conditions.
  • Whether you are going to have other cancer treatment types.
  • How close the tumor is to normal radiation-sensitive tissues.
