Israeli Research Sees No Need For Chemotherapy If Breast Cancer Is Detected Early

Israeli researchers have found that breast cancer can be effectively treated without chemotherapy if the disease is detected in its early stages, the Hebrew language newspaper “Yedioth Ahronoth” reports.

The study was conducted by senior oncologists from several Israeli hospitals.

According to the World Health Organisation (WHO), breast cancer is the most frequent cancer among women, impacting 2.1 million women each year.

It is estimated that 627,000 women died from breast cancer in 2018, about 15 per cent of all cancer deaths among women.

Today, most breast cancer patients are diagnosed in the early stages, giving room for surgery to remove the tumour with very high chances of recovery.

However, after surgery some patients are advised to undergo chemotherapy treatment to eliminate microscopic cancer cells that were not removed in the surgery.

Chemotherapy often has serious health consequences over the years, including a serious harm to the immune system, which may be life-threatening.

In the Israeli study, published in the journal npj Breast Cancer, the researchers examined 1,365 women with breast cancer in over 10 years.

As part of the study, the women underwent an oncotype test to determine the genetic profile of the tumours, and those with a low risk of recurrence were advised to give up chemotherapy.

It was found that among 97.4 per cent of those who gave up chemotherapy, the disease did not recur, and the mortality rate among this group was only 0.7 per cent.
