Science took another big step in the treatment of cancer. An international panel of scientists analyzed a specific type of tumor in the thyroid gland and defined that disease should not be classified, precisely, as a cancer.

The discovery, published in the prestigious journal JAMA Oncology, meant a before and after to treat that health problem. Thus, patients who suffer from it in the future will be able to avoid light therapy, gland removal or annual controls for the rest of their lives. "If it's not cancer, let's not call it cancer. There's an increasing concern in the medical community about the terms we use, which do not match the biology of cancer," said Barnett Kramer, director of the prevention division Against cancer of the National Cancer Institute, in the USA.
