en Letters to the Editor <div style="text-align: justify;"><span style="font-size:14px;"><span style="font-family:Times New Roman;">Cancer is a life-threatening disease that has negative effects on the physical, psychological, social, economic, and spiritual aspects of patients and their families [1]. Cancer diagnosis puts the patient and family in a state of &ldquo;existential crisis.&rdquo; The existential crisis is about the first hundred days after the diagnosis in which patients and their families worry about life and death. During the existential crisis, patients and their families reach the peak of vulnerability. Their existence and way of life are endangered and many of them will look for a meaning to attribute to the disease according to their reasons [2]. Family attitude towards the disease, its symptoms, and its complications has special effects&nbsp;on patient care, thus, one of the main care policies for the family is to gain more knowledge and understanding of the disease process and treatment. Therefore, many psycho-oncologists consider cancer as a familial disease [3].</span></span></div> cultural factors,cancer,sharing cancer news 1 2 http://mcijournal.com/browse.php?a_code=A-10-554-1&slc_lang=en&sid=1 Moslem Arian arianmoslem@yahoo.com 10031947532846003175 10031947532846003175 No Department of Counseling, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran Seyedeh Fahimeh Shojaei shojaee.fahimeh@yahoo.com 10031947532846003176 10031947532846003176 Yes Firoozgar Clinical Research and Development Center (FCRDC), Iran Univer- sity of Medical Sciences (IUMS), Tehran, Iran
