Radiation therapy uses high-energy radiation to kill cancer cells and shrink tumors. It works by damaging the DNA of cancer cells, which grow and divide faster than normal cells. Radiation treatment can be delivered externally through machines or internally through radioactive implants placed near cancer cells. Researchers are studying ways to improve radiation therapy through radiosensitizers to make cancer cells more vulnerable and radioprotectors to protect healthy cells from radiation damage.

1.
2. What is radiation therapy?
⢠With the advancement in technology, now it is possible to heal
cancer. This procedure is called radiation therapy
⢠Radiation therapy uses high-energy radiation to shrink tumors and
kill cancer cells.
⢠X-rays, gamma rays, and charged particles are types of radiation
used for cancer treatment.
⢠The radiation may be delivered by a machine outside the body
(external-beam radiation therapy), or it may come from radioactive
material placed in the body near cancer cells (internal radiation
therapy, also called brachytherapy).
⢠Systemic radiation therapy uses radioactive substances, such
as radioactive iodine, that travel in the blood to kill cancer cells.

3. How does radiation therapy kill
cancer cells?
⢠Radiation therapy kills cancer cells by damaging their DNA
⢠Cells normally grow and divide to form new cells. But cancer
cells grow and divide faster than most normal cells. Radiation
works by making small breaks in the DNA inside cells.
⢠Radiation treatment is planned to damage cancer cells, with as
little harm as possible to nearby healthy cells

4. How is radiation therapy given?
Radiation therapy can be given in following ways:
⢠External beam radiation therapy, in which the beam of radiation is
focused onto the treatment area by an external machine.
⢠Internal radiation therapy, such as brachytherapy, in which a
radioactive substance is placed in or close to the cancerous tissue in
a temporary or permanent implant.
⢠Systemic radiation therapy, Radioactive drugs given by mouth or
put into a vein are used to treat certain types of cancer. These drugs
then travel throughout the body.
The type of radiation you might get depends on the kind of cancer
you have and where it is. In some cases, more than one type is
used.

5. When will a patient get radiation
therapy?
⢠A patient may receive radiation therapy before, during, or after
surgery.
⢠Some patients may receive radiation therapy alone, without surgery
or other treatments.
⢠Some patients may receive radiation therapy and chemotherapy at
the same time.
⢠The timing of radiation therapy depends on the type of cancer
being treated and the goal of treatment (cure or palliation).

6. What research is being done to
improve radiation therapy?
⢠Researchers are also studying radiosensitizers and
radioprotectors, chemicals that modify a cell's response to
radiation:
⢠Radiosensitizers are drugs that make cancer cells more
sensitive to the effects of radiation therapy. Several agents are
under study as radiosensitizers. In addition, some anticancer
drugs, such as 5-fluorouracil and cisplatin, make cancer cells
more sensitive to radiation therapy.
⢠Radioprotectors (also called radioprotectants) are drugs that
protect normal cells from damage caused by radiation
therapy. These drugs promote the repair of normal cells
exposed to radiation. Many agents are currently being studied
as potential radioprotectors.

7. Treatment in Pune
You can easily find so many hospitals in Pune that treat cancer using
radiation therapy. Prominent hospitals like Poona hospital, Lakshya
Cancer Hospital, Bora hospital, Express clinic, Dr. Deoâs Surgical
Clinic etc. are the few hospitals and treatment centers that you can
look up to for getting cancer treated. So get your appointment fixed
and go for a session to get your treatment done at the right time.
