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.
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.
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.
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:
- Hair loss.
- 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.
