Radiation Therapy

Radiation therapy, also called Radiotherapy, is a very effective way of treatment and is towards the goal to destroy cancer cells that may still remain after this operasi.Radiasi can reduce the risk of recurrence.

HOW DOES RADIATION WORK TO TREAT CANCER?

Radiation is energy that brought a wave or particle flow. It can change the genes (DNA) and several molecules of the cell. These genes control how cells grow and divide in the body. To determine how radiation works for treatment, perama of all we must know the life cycle of normal cells in the body. The cell cycle consists of 5 phases, the first is the separation of a cell in the body. When the cells separate or divide into 2 cells is called mitosis.

Cycle Cell:
Go = Tues being silent
G1 = RNA and proteins are made
S = DNA made
G2 = Equipment for division (mitosis) is built / made
M = Mitosis (Tue split into two)

Go phase (resting stage):

Tues not yet started to divide. Tues spend the most time is in this phase. Depending on the type of cells, this step can last from several hours to many - years. When cells get the code to double, then later he will travel to phase Go.

G1 Phase:

During this phase, the cell starts to make more protein in order to prepare for the split.This phase lasts between 18 to 30 hours

Phase S:

Chromosome - chromosome that contains the genetic code (DNA) is copied so that the two newly formed cells that will have the same amount of DNA. This phase lasts between 18 to 20 hours.

G2 Phase:

This phase is the phase moments of the cell starts to divide into 2 cells. It lasted 2 to 20 hours

Phase F:

This phase is the phase when the cell divides into 2 cells. This phase lasts only 30 or 60 minutes.
The cell cycle is very important in cancer treatment, because radiation is usually effective in working with cells that are active or rapidly dividing. This treatment is not effective in cells that are in the resting phase (Go), or cells that cuts slow.RADIOSENSITIVITY is the means used to illustrate how easy it is to a cell damaged by radiation.
Radiation therapy to attack cancer cells that are dividing. But it can also on normal cells. Damage to normal cells is what causes side effects. Each time radiation therapy is given, it will perform equally between destroying the cancer cells and protecting normal cells.
In the past, in the estimate that once an area is irradiated, the next in the same area can no longer do because of radiation therapy damage normal cells due to treatment that. But new research states that in some situations the two may be given radiation therapy.
