Individuals with cancer are at increased risk for suicidal ideation and behaviour when compared to the general population. Suicidal thoughts are sometimes minimized and considered by clinicians as a normal reaction to diagnosis of oncological disease. Less severe forms of suicidal ideation, such a fleeting wish to die may happen in all stages of the disease.

We aim to highlight the cases of cancer patients that present an imminent suicide risk and its related psychopathological aspects, psychosocial and physical risk factors that may increase the probability of suicidal attempt.

Non systematic literature review through the Medline and Clinical Key databases, with time constraints.

Individuals with cancer have twice the risk of suicide compared to the general population. It was found that suicidal thoughts are more common in patients with advanced disease, in hospital or in palliative care settings or in those who are experiencing severe pain, depression, cognitive impairment or delirium. The first months following the diagnosis are the period of greatest risk and the highest suicide risk occurs in men with respiratory cancers. Death by suicide occurs more often in cancer patients in the advanced stages of disease.

An appropriate therapeutic response should include empathy, active listening, management of realistic expectations and permission to discuss psychological distress. The first intervention should focus on determining imminent risk of suicidal behaviour and act for patient safety.
