This is the best summary I could come up with:

Older women with early, low-risk breast cancer may not need to receive radiation treatment, according to a new research finding that experts say could spare patients from some harmful side effects.

The study tracked women 55 years and older with low-risk, stage 1 breast cancer, and found they could be effectively treated with just surgery to remove the lump and hormone therapy.

Whelan, also a Canada Research Chair in breast cancer, says if women fit the above criteria, then it’s clear that their risk of recurrence is low, so there isn’t “really any advantage” to having radiation treatment.

While the short-term side effects have subsided and McNabb is considered cancer free, she says she still experiences mental fog and feels “scattered” on occasion — something she attributes to the radiation.

“There are many, many women who go through treatments and, because they’re shell-shocked, they don’t have an opportunity to really analyze or think, because things happen so quickly,” said McNabb, noting that’s why the studies are important.

Whelan’s findings were initially discussed in June last year at the American Society of Clinical Oncology Annual Meeting in Chicago, but have now been peer-reviewed and published in full.
