Again, there
was no increase of lymphocytes in the control group and
only a 2% non-signifiant increase in the relaxation group.
The sixth study was a randomized controlled clinical trial
(Billhult et al., 2008) in which 22 breast cancer patients
were allocated either to a group receiving massage with
a cold-pressed vegetable oil or to a visit-only control
group. No signifiant differences in CD4 or CD8 cells
were found. The last study (Imanishi et al., 2009) was
a non-randomized controlled trial with 12 women with
breast cancer and found statistically signifiant increases
in WBCs and lymphocytes following aromatherapy
massage twice a week for four weeks.
