The history of human and animal cancers date back to antiquity. The earliest written document on cancer appeared on Egyptian papyrus. For centuries, the theory of "four humors" was the primary hypothesis that explained the cause for cancer. Finally, in the 19th century a new era began with the detection of the cellular origin of cancer; in due course, the nature of this lethal disease was better recognized and led to further achievements in cancer treatment. ⋯ After the advent of radiotherapy and chemotherapy as two complementary therapeutic modalities to surgery, the campaign against cancer has improved. However, cancer remains a major health challenge that accounts for substantial morbidity and mortality worldwide. The present paper briefly reviews the history of cancer in Iran, particularly during the last decades of the 20th century.

This study was performed to determine the lifetime prevalence of psychiatric disorders concomitant with attention deficit/hyperactivity disorder (ADHD) among primary school students. ⋯ The results of this study indicated that the frequency of other psychiatric comorbidities in primary school students with ADHD is high that may affect disease course and treatment. Hence, evaluation for other comorbidities in ADHD patients should be considered.

The geographic map of cancer prevalence differs due to environmental and dietary factors in various populations. High prevalence of a number of cancers in some regions is thought to be attributed to local dietary habits. Dorema aucheri (Bilhar) is used commonly as an herbal medicine in some regions including Iran. The aim of this study was to evaluate whether Dorema aucheri has carcinogenic effects in albino mice or not. ⋯ Dorema aucheri has potential hepatotoxic capacities and possibly this may be related to the high prevalence of cancer in some regions of Iran.

Leishmaniasis is a zoonotic infection caused by a protozoa belonging to the genus Leishmania. Its clinical manifestations range from a self-healing cutaneous leishmaniasis (CL) to lethal visceral leishmaniasis. We aim to examine the quality of life of patients with CL in Kerman, Iran. ⋯ CL significantly affects the quality of life of patients. Further studies are suggested to examine the effect of its treatment on the quality of life in these patients.

Esophageal cancer (EC) is the eighth common cancer and the sixth most common cause of death from cancer worldwide. Esophageal squamous cell carcinoma (ESCC) remains the most common type of EC in the developing world and an important health problem in high-risk areas. Most of ESCC cases present in late stages, resulting in delayed diagnosis and poor prognosis. ⋯ Nonendoscopic methods may be more applicable in these populations for population-based screenings. The limitations (questionable validity and costs) of new endoscopic imaging modalities, including narrow-band imaging (NBI), made them inappropriate to be used in population-level ESCC screening programs. Low-cost, less-invasive endoscopic imaging methods with acceptable diagnostic performance may make screening of ESCC in high-risk areas cost-effective.
