The American Cancer Society predicts 40,000 deaths from breast cancer among American women in 2014.  In desperate need to increase the chance of survival, women seek adjuvant therapy after surgery such as chemotherapy, radiation and/or hormone therapy.  Yet, not all women complete their treatment due to negative side effects.  Though stress management seems to alleviate some side effects, limited research has not determined the association between stress management and the side effects of breast cancer treatment.  Therefore, this research aimed to study the above association and the trend among breast cancer women who practiced stress management(s), with focus on motivating factors.  Based on information that certain stress management activity is frequently recommended, it was hypothesized that there will be a strong association between the most practiced stress management and the most alleviated side effect.  Out of 438 women, 184 practiced stress management during breast cancer treatment.  The result using odds ratio showed strong association between aromatherapy, a stress management not frequently practiced, and the alleviation of multiple side effects such as headache, skin irritation, nerve pain, sore mouth and lymphedema.  Thus, the analysis concluded that it was not the most practiced stress management that alleviated the most side effects.  Furthermore, strong association was found between stress management practice and fellow cancer patient support and counseling support, weak association between family support, and no association between financial status which may indicate that stress management awareness may be the motivating factor to practicing stress management, an important key to cancer survival.
