Distress varies in level of intensity depending on severity of disease as well as phase of treatment (Simonton & Sherman, 1998). The greater levels of distress are positively associated with greater severity of disease (Maunsell, Brisson & Deschenes, 1992; Schag, Ganz, Polinsky, Fred, Hirji, & Peterson, 1993). Further, a patient’s phase of life has a significant impact on adjustment: younger patients demonstrate greater levels of distress than older patients (Simonton & Sherman, 1998; Vinokur, Threatt, Vinokur-Kaplan, & Satariano, 1990). In breast cancer patients, advanced age has been associated with increased social activities and contacts, with better mental health, perceived quality of life, and functioning (Vinokur et al., 1989) | International Agency for Research on Cancer ếổm World Health Organization PRESS RELEASE N 208 31 May 2011 IARC CLASSIFIES RADIOFREQUENCY ELECTROMAGNETIC FIELDS AS POSSIBLY CARCINOGENIC TO HUMANS Lyon France May 31 2011 -- The WHO International Agency for Research on Cancer IARC has classified radiofrequency electromagnetic fields as possibly carcinogenic to humans Group 2B based on an increased risk for glioma a malignant type of brain cancer1 associated with wireless phone use. Background Over the last few years there has been mounting concern about the possibility of adverse health effects resulting from exposure to radiofrequency electromagnetic fields such as those emitted by wireless communication devices. The number of mobile phone subscriptions is estimated at 5 billion globally. From May 24-31 2011 a Working Group of 31 scientists from 14 countries has been meeting at IARC in Lyon France to assess the potential carcinogenic hazards from exposure to radiofrequency electromagnetic fields. These assessments will be published as Volume 102 of the IARC Monographs which will be the fifth volume in this series to focus on physical agents after Volume 55 Solar Radiation Volume 75 and Volume 78 on ionizing radiation X-rays gamma-rays neutrons radio-nuclides and Volume 80 on non-ionizing radiation extremely low-frequency electromagnetic fields . The IARC Monograph Working Group discussed the possibility that these exposures might induce long-term health effects in particular an increased risk for cancer. This has relevance for public health particularly for users of mobile phones as the number of users is large and growing particularly among young adults and children. The IARC Monograph Working Group discussed and evaluated the available literature on the following exposure categories involving radiofrequency electromagnetic fields occupational exposures to radar and to microwaves environmental exposures associated with transmission of signals for radio television .
