癌症是一种为患者带来严重心理问题的疾病，因此对那些试图支持他们的人提出了挑战。sprah和sostaric（2004）指出阶段通过那些身患癌症通常会。否认通常是第一阶段，这有助于减少焦虑的直接水平，虽然可能是有害的，如果它继续太长。一些研究人员发现，采用否认现实的想法的倾向会对癌症结果产生不利影响。焦虑和抑郁通常是与癌症相关的其他阶段。一些研究表明抑郁症可以预测疾病的进展。这些研究的问题是很难区分的癌症和癌症的结果是通常的问题相关研究告诉原因和结果之间的差异的症状之间的区别。 有很多研究认为“积极思考”或社会支持可能有助于癌症的医疗结果。早期的研究表明，可能有这种心理因素医学重要性，后来元分析研究给出了相互矛盾的指示（garrsen，2002）。反对那些主张“积极思考”的人，一些研究人员说，癌症患者不应该感到压力，试图积极思考，因为有疑问，这是否有任何好处。哈切特的朋友，symister & Wadhwa（1997）检查了这些因素在研究调整疾病是由人际期望的影响。在这项研究中的患者患有肾脏疾病和假设，对患者的疾病的家庭的期望是从现实的明显不同。这样做的结果是，病人可以看到，他们的家人期望他们能够更能继续他们的日常生活比他们。这影响了他们对疾病的适应。在某种程度上，其他人的期望会在恢复中扮演一个角色-仅仅强迫一个人的“积极思考”可能不会有帮助.
Cancer is a disease that present serious psychological problems for sufferers, and so provides challenges for those attempting to support them. Sprah & Sostaric (2004) point out the stages through which those suffering from cancer will often go. Denial is normally the first phase, which helps to reduce the immediate levels of anxiety although can be detrimental if it continues too long. Some researchers have found that the tendency to adopt frames of mind that deny reality can adversely effect cancer outcomes. Anxiety and depression are other stages often commonly associated with cancer. Some studies have shown that depression may predict the progression of the disease. The problem with these studies is that it can be difficult to tell the difference between the symptoms of the cancer and the results of the cancer - it's the usual problem in correlational studies of telling the difference between cause and effect.
There has been much research into the idea that 'thinking positive' or social support might help in the medical outcomes of cancer. While early studies had shown that there might be medical importance in these kind of psychosocial factors, later meta-analytical studies have given contradictory indications (Garrsen, 2002). In opposition to those advocating 'positive thinking', some researchers say that cancer sufferers should not feel pressured into trying to think positive as there is doubt over whether this has any benefit. Hatchett, Friend, Symister & Wadhwa (1997) examined some of these factors in their study of adjustment to illness was affected by interpersonal expectations. The patients in this study were suffering from renal disease and it was hypothesised that the families expectations of the sufferer's disease were significantly different from the reality. The result of this was that the patient could see that their families expected them to be more able to continue their everyday life than they were. This affected their adjustment to their illness. To some extent then, other people's expectations are going to play a role in recovery - simply forcing 'positive thinking' on a person might not be helpful
