Medical science continues to advance. In line with this progress, scientists have now shared encouraging news regarding breast cancer. A new study reveals that hundreds of thousands of patients suffering from this disease may not require chemotherapy. Scientists have developed a DNA test capable of identifying which patients require chemotherapy as part of their treatment and which do not.

The study was conducted by University College London. More than 4,000 individuals from the United Kingdom, Norway, Sweden, Australia, New Zealand, and Thailand participated in this research. All participants were over the age of 40 and had recently been diagnosed with breast cancer. This information regarding the necessity of chemotherapy emerged after the new DNA test was administered to the patients during the study.

Scientists utilized a DNA test known as “Prosigna.” This test assesses the activity levels of 50 specific genes known to play a role in the progression of breast cancer, thereby calculating the patient’s risk of cancer recurrence.

The potential side effects of chemotherapy include fatigue, nausea, hair loss, a weakened immune system, and issues with fertility. The study demonstrated that it is possible to spare more than two-thirds of the participants from enduring these adverse side effects of chemotherapy. These patients can be effectively treated solely through hormone therapy.

Following the publication of the study’s results, University College London announced that more than 5,000 patients under the care of the UK’s National Health Service will no longer need to undergo chemotherapy each year. Karen Bonham, a resident of Cardiff, is delighted by this news; she was also a participant in the study. Karen remarked, “This is news of immense relief.” “Hearing this feels like Christmas.”

Following the receipt of research results, University College London has now announced that more than 5,000 patients under the care of the UK’s National Health Service will no longer require annual chemotherapy. Karen Bonham, a resident of Cardiff, is delighted by this news; she, too, had participated in this study. Karen remarked, “This is news of immense relief. Hearing this feels just like Christmas.”

The findings of this new study were scheduled to be presented yesterday—Saturday—at a cancer conference hosted by the ‘American Society of Clinical Oncology’ in Chicago, USA. Cancer specialist Professor David Miles told the BBC, “We can now confidently assume that many patients will derive absolutely no benefit from chemotherapy. Therefore, there is no need to treat them with chemotherapy.”
