Some Canadian researchers discovered that only three weeks of radiation for the women who have an early-stage breast cancer are correspondent with the five weeks or more of the same treatment. The researchers tracked 1,234 women for almost 12 years and noticed that a shorter treatment does the same with the longer one.

This study has just made an easier life for most of the sick women, as they don’t have to suffer longer than three weeks. The results were presented on Monday at a conference in Boston and they also showed the specialty clinics that they can shorten the treatment and treat more women, but they also don’t have tobuy more machines.

According to the researchers, these new findings could change the standard of care in the United States, as the longer treatments submitted the women for five to seven weeks of treatment. It was hard for many of them, especially if they had to work, grow their children or they just lived far from the clinics.

Dr. Anthony L. Zietman, a professor of radiation oncology at Harvard Medical School and president-elect of the American Society for Therapeutic Radiology and Oncology, said that the new findings are available only for the women with early cancer, which was removed by lumpectomy and didn’t spread to the lymph nodes.

Only 30-40% of the 180,000 women who develop cancer during a year can go after the new discovery.

The radiation keeps the cancer from recurrence in the same breast. It kills any tumor cells that might have been evaded surgery and chemotherapy. The cancer cells are very sensitive to the radiation, not like the normal ones. So the radiation must be done in certain equilibrium, to kill the tumors but not to affect other parts of the body.
