Omega-3s improve energy in cancer survivors
Many people treated for cancer have lingering fatigue
after
therapy ends, which may be
aggravated by chronic inflammation, doctors said.
Omega-3s have
reduced inflammation in
healthy people, leading doctors to examine its effect in
breast
cancer survivors .
In this study, doctors measured the diets of 644
survivors with
stage I to stage IIIA breast
cancer, and followed up 39 months after diagnosis.
Overall, 42
percent complained of being
chronically fatigued three years after diagnosis. Women
with the highest levels of C-reative
protein (CRP), a sign of inflammation, were nearly twice
as
likely to be fatigued as women
with low CRP levels .
When doctors looked at the ratio of omega-3s to omega-
6s in the
diet, women who got the
most omega-3s compared to omega-6s were half as
likely to be chronically fatigued as
women who got the least
omega-3s .
Vitamin B6 may help prevent postmenopausal breast cancer
Vitamin B6 helps maintain the health of red blood cells, the
nervous system, and parts of the immune system . In this
study, doctors measured
circulating levels of vitamin B6 in 706 postmenopausal
women before they were diagnosed with
breast
cancer and compared
them to vitamin B6 levels in 706 healthy postmenopausal
women .
Compared to women
with the lowest levels, women with the highest circulating
levels of vitamin B6 were 30
percent less likely to develop invasive breast cancer .
Doctors said these results suggest a role for vitamin B6 in
preventing postmenopausal breast cancer .
