developments in cancer research

According to the senses about 5% of the people are having cancer. The
physicians conclude that unnecessary uses of drugs in a heavy dose,
smoking and irregular diet consumption are the main reasons for the
growth of cancer. If cancer is identified in its earlier stages, it
can be cured
And if it has grown then the possibility of the person to be cured is
very less until the part is removed from the body of the patient.
Burning away of the cancer using laser techniques is not effective for
internal cancer like brain cancer or stomach cancer. Still now the
scientists haven’t found an effective medicine to cure the cancer. The
medicines now are only to prevent the growth of the cancer and it
is not much effective. But for external cancers the destructive
techniques like burning or cutting off the part from the body is
successful to prevent the growth of it to other parts of the body.
