Study: One-week breast cancer radiotherapy proven as safe and effective as standard three-week treatment

Presented at ESTRO 2025 in Vienna, Austria, a 10-year study involving over 4,000 UK patients confirms that a one-week course of post-surgery radiotherapy is just as safe and effective as the traditional three-week regimen for early-stage breast cancer patients. These long-term results from the FAST-Forward trial could further reduce the burden on breast cancer patients worldwide, and expand access to life-saving radiotherapy.

The phase III randomized trial followed up patients for ten years and showed that a shorter, five-day radiotherapy schedule provides a similar level of cancer control as the standard 3-week treatment, without additional long-term side effects. This builds on previous five-year results that have already led to a shift in clinical practice.

Breast cancer is one of the most common cancers globally, and radiotherapy plays a critical role in reducing the risk of recurrence after surgery. A shorter treatment course offers major benefits:

"This 10-year analysis provides definitive long-term evidence that one-week radiotherapy to the breast is a safe, effective, and more practical option for breast cancer patients," said Professor Murray Brunt.

Professor Judith Bliss said, "The FAST-Forward trial revolutionized cancer treatment by reducing the standard radiotherapy from three weeks to just one week, without compromising effectiveness.

FAST-Forward is a major international clinical trial investigating the best way to deliver radiotherapy for early breast cancer. It compared the standard three-week schedule (40Gy in 15 treatments) with a shorter, one-week schedule (27Gy or 26Gy in five treatments). The FAST-Forward trial is part of a long-term program of research into improving breast cancer radiotherapy at The Institute of Cancer Research (ICR).

Less is probably good. My partner had 6 weeks of radiation along with anti-testosterone for prostate cancer. I also had done research and had him take zinc and Quercetin to help get virus killer ZINC into infected cells. This was based on Dr. Zelenko’s finding that HCQ helped zinc enter cells to kill Covid virus. Also a 2020 study of 9 common cancers, including prostate, colon, liver, and breast, which found ALL 9 cancer tissues were deficient in zinc while healthy tissues were well supplied with zinc.

I had begun taking a number of supplements to successfully reverse my cataracts and avoid surgery. I discovered that Astaxanthin was reported to shorten the life of cancer cells, and make longer the life of normal cells, so added that to the supplements I gave my partner and brother with metastatic liver cancer (from colon cancer), being treated with some reduction of cancer tissues by chemo. My partner is now completely clear of cancer—PSA 0.001. My brother’s doctors were contemplating going inside to reduce the size of his shrinking cancers. THen my brother had his 4th Covid shot, and within two weeks was on a down glide to death with a much more severe chemo and growing tumors.

So I would definitely recommend taking Quercetin and zinc with any cancer, unless you have a doctor who will give you HCQ or Ivermectin to take with the zinc. Also take Astaxantin, and check Google for nutrition and supplements to use while dealing with cancer, and information on safe or effective doses that have been discovered and used.
