Hundreds of thousands of persons each year fall to prey some types of cancer; but new methods of

radiation therapy have enabled doctors to save more lives than ever before. Medical researches have

developed several experimental forms of this time-honored cancer treatment that seem effective in

fighting the diseases.

One promising approach involves exposing cancer cells to radiation by implanting a radioactive

source directly into the malignant tissue. This process greatly increases the dosage and thus the

effectiveness of the treatment. Another technique utilizes drugs to make cancer cells more susceptible to

the effects of radiation and to make normal cells more resistant. Certain drugs are able to neutralize the

genetic framework of cancer cell, thus making them more easily effected by radiation. Both techniques

have been more positive results in the treatment of inoperable brain tumors.

These and other methods have helped to raise the recovery rate for cancer victims from 30% forty

years ago to around 50% today. This is encouraging news for those who fall prey to one of the world’s

leading killers.
