Intense resistance training helped breast cancer survivors regain strength faster

By AI, Created 10:51 AM UTC, May 20, 2026, /AGP/ – A study presented at the American Society of Breast Surgeons annual meeting in Seattle found that a three-month resistance training program produced significant gains in strength, mobility and balance for recent breast cancer survivors, including patients who had mastectomy and axillary lymph node dissection. Researchers say the findings could support earlier, safer return to daily activity after surgery.

Why it matters: - Breast cancer survivors often face long recoveries after surgery, radiation and other treatments. - The study suggests intensive resistance training can speed functional recovery instead of delaying it for years. - Researchers say the gains could improve quality of life and help survivors return to daily activities sooner. - The findings also challenge conservative views about how much weight post-surgery breast cancer patients can safely lift.

What happened: - Researchers presented results this week at The American Society of Breast Surgeons annual meeting in Seattle. - The study examined a structured, three-month total-body resistance training program for recent breast cancer survivors. - The program included women treated with mastectomy or lumpectomy, with axillary lymph node dissection performed as needed. - Investigators pooled data from three prior studies on the safety of the exercise program, including one study that added a nutritional component. - All studies were conducted at the Allegheny Health Network Exercise Oncology and Resiliency Center in Pittsburgh.

The details: - The analysis included 197 recent breast cancer survivors who completed the program. - Of the participants, 85 had mastectomy and 112 had lumpectomy. - Twenty-six participants underwent axillary lymph node dissection, and 171 did not. - The 171 without ALND included women who had no axillary staging or sentinel lymph node biopsy. - Researchers measured body composition before the program with ultrasound and bioimpedance analysis. - The team assessed function with standardized tools including functional movement screening, balance screening and weight-lifting evaluations. - Statistical testing found no significant baseline differences in body composition or functional measures across the pre-exercise groups. - All women showed significant improvement in body composition and function after the program. - Women treated with mastectomy and lumpectomy without ALND had similar gains across all study measurements. - Those improvements included body mass index, muscle mass, functional movement screening scores and weight loads lifted in multiple movement patterns. - Participants who had ALND trended lower only on the functional Y-balance test. - Older age and radiation therapy were linked to lower pre-exercise functional movement screening scores. - Those factors explained less of the post-program improvement, which investigators said points to the exercise program as the main driver of gains. - Colin Champ, an associate professor at Allegheny Health Network and a certified strength and conditioning specialist, said many women in the program were deadlifting 100-pound weights by the third week and 200-pound loads by the end of the program. - Champ said the program used a full range of motion and rapidly intensified in a way similar to early professional athletic training. - Champ said women treated for breast cancer often lose range of motion and muscle mass after more than a year of physically and psychologically difficult therapies. - Champ said the study shows even women who had extensive surgery can make major gains in a few months. - Champ said patients do not have to wait years to improve function and lifestyle.

Between the lines: - The study is small and focused on a specific exercise center, so the results may not apply to every survivorship setting. - Still, the findings add to evidence that carefully structured high-level exercise may be safe and effective even after extensive breast surgery. - Champ said the results support making exercise part of standard survivorship care.

What’s next: - The research adds support for broader use of resistance training in breast cancer recovery programs. - The exercise model already is delivered routinely to cancer patients at the Allegheny Health Network center. - Further studies could test whether the same results hold in larger and more diverse patient groups.

The bottom line: - Intensive resistance training may help breast cancer survivors rebuild strength, mobility and balance faster than traditional recovery assumptions suggest.
