The answer is A. Fang et al (NEJM, 2012) demonstrated that compared to cancer-free persons, the OR of suicide in cancer patients is12.0 in the first week after a diagnosis and remains elevated at 3.1 during the 1st year. Lung, pancreatic, esophageal and liver cancer (not prostate cancer) conferred the highest suicide risks in this and other studies. Cancers with a poor prognosis did seem to confer a higher risk, but variables such as chemotherapy and hormonal treatment have not conferred increased risk in prior studies. Although male gender is a general risk for suicide, the OR in cancer vs cancer free patients was 3.2 for males and 2.5 for females, suggesting that shorter interval since diagnosis is a stronger risk factor.
