Analysis: Obesity Links to Earlier Mortality for Breast Cancer Survivors

A new study involving the emerging research on lifestyle’s role in breast cancer survivorship suggests that obesity — both before and after a breast cancer diagnosis — is associated with earlier death from cancer or other causes, compared to women at a healthy weight. Survivor

The paper was published yesterday in the Annals of Oncology. It adds to a complex and relatively new area of research: what survivors can do to lengthen life and stay healthy.

In a major report on breast cancer survivorship due this Fall, World Cancer Research Fund International’s Continuous Update Project (CUP) expert panel will consider this latest paper as it works to shape official recommendations for cancer survivors. AICR is the US member of World Cancer Research Fund International.

The Annals of Oncology paper was written by a team of scientists involved in the CUP, including Anne McTiernan, MD, PhD, Director of the Prevention Center at the Fred Hutchinson Cancer Research Center. The paper found that “increased body size is significantly related to survival after a diagnosis of breast cancer…” said Dr. McTiernan. But the findings are not proof, she says, more research is needed. Continue reading


Study: Cancer Survivors Gain Strength with Strength Training

Among the many side effects of cancer treatment, muscle loss is one that can make daily tasks such as lifting groceries and running errands become challenging. Dumbbell-SP005620_7_300w

Now an analysis of the research suggests that survivors who lift weights and do other resistance exercises improve both arm and leg muscles. And for the strongest arms, resistance training at a low to moderate intensity works the best.

The review was published last week in Medicine & Science in Sports & Exercise.

The new study looking only at randomized controlled trials — considered the gold standard of studies — included studies on resistance training among cancer patients and survivors. The researchers ended up with 11 relevant studies that included almost 1200 people. Each comparing a resistance training  group against a comparison. The majority of studies worked with breast and prostate patients and survivors.

Participants had conducted resistance training exercises from 3 months up to a year. Most involved two training sessions a week. Continue reading


New Analysis: Lifting Weights Helps Survivors

Dumbbell-SP005620_7_300wWhen you read about the health benefits of exercise for cancer survivors it’s common to lump all exercise together. After all, there’s no bad form of exercise.

A new review of the research now suggests that lifting weights, sit-ups and other forms of resistance exercises can help survivors both during and after treatment gain muscle strength, reduce body fat, and improve fatigue.

The improved effects seen with arm strength and body fat were most pronounced in survivors who engaged in low to moderate intensity exercises compared to those of higher intensity.

Doing resistance exercises at least two times per week led to survivors able to increase the amount of weight lifted, on average, 34 pounds (15.5 kilograms) for legs and 16 pounds (7.3 kilograms) for arms.

The study was published in the early online issue of Medicine & Science in Sports & Exercise. Continue reading
