Stress is an inevitable part of life. Recent studies have shown that chronic stress can induce tumorigenesis and promote cancer development. This review describes the latest progress of research on the molecular mechanisms by which chronic stress promotes cancer development. Primarily, chronic stress activates the classic neuroendocrine system [the hypothalamic-pituitary-adrenal HPA axis] and the sympathetic nervous system SNS and leads to a decline and dysfunction of the prefrontal cortex and the hippocampus under stress.

Stress and breast cancer: a systematic update on the current knowledge

Despite the high incidence and mortality rate of breast cancer BC in Ghana, little attention has been given to the issue of how adult women cope with having BC. The aim of this study was to explore the challenges, coping strategies, and support systems among women diagnosed with BC in Ghana. A systematic random sampling technique was used to select women with a confirmed diagnosis of BC. The most and least adopted active coping strategies were religious coping and humors, respectively. Self-distraction and substance use were the most and least adopted avoidant coping strategies, respectively. This study demonstrates that women diagnosed with BC in Ghana adopt varied coping strategies to deal with these challenges.

Chronic Stress Promotes Cancer Development

Metrics details. Women diagnosed with breast cancer frequently attribute their cancer to psychological stress, but scientific evidence is inconclusive. We investigated whether experienced frequency of stress and adverse life events affect subsequent breast cancer risk. Breast cancer incidence was analysed with respect to stress variables collected at enrolment in a prospective cohort study of , women in the United Kingdom, with incident breast cancer cases. Relative risks RR were obtained as hazard ratios using Cox proportional hazards models.

A vast body of research has been carried out to examine the relationship between psychological stress and the risk of breast cancer.

The present study was undertaken to evaluate the place of oxidative stress on breast cancer. Lipid peroxidation as evidenced by malondialdehyde MDA and the status of the antioxidants superoxide dismutase SOD , catalase CAT , and glutathione peroxidase GPx were estimated in tissues of 10 fibroadenoma and 40 breast cancer patients. The results of our study have shown higher oxygen-free-radical production and decreased CAT activity support the oxidative stress hypothesis in breast carcinogenesis.

ТРАНСТЕКСТ себя оправдал. В интересах сохранения в тайне этого успеха коммандер Стратмор немедленно организовал утечку информации о том, что проект завершился полным провалом. Вся деятельность в крыле, где размещалась шифровалка, якобы сводилась к попыткам зализать раны после своего фиаско ценой в два миллиарда долларов. Правду знала только элита АНБ - ТРАНСТЕКСТ взламывал сотни шифров ежедневно. В условиях, когда пользователи были убеждены, что закодированные с помощью компьютера сообщения не поддаются расшифровке - даже усилиями всемогущего АНБ, - секреты потекли рекой. Наркобароны, боссы, террористы и люди, занятые отмыванием криминальных денег, которым надоели перехваты и прослушивание их переговоров по сотовым телефонам, обратились к новейшему средству мгновенной передачи сообщений по всему миру - электронной почте. Теперь, считали они, им уже нечего было опасаться, представ перед Большим жюри, услышать собственный записанный на пленку голос как доказательство давно забытого телефонного разговора, перехваченного спутником АНБ.

Она снова и снова слышала свое имя. Сьюзан… Сьюзан… И в этот момент она все поняла. Дрожащей рукой она дотянулась до панели и набрала шифр. S…U…Z…A…N И в то же мгновение дверца лифта открылась. ГЛАВА 108 Лифт Стратмора начал стремительно спускаться. В кабине Сьюзан жадно вдохнула свежий прохладный воздух и, почувствовав головокружение, прижалась к стенке лифта. Вскоре спуск закончился, переключились какие-то шестеренки, и лифт снова начал движение, на этот раз горизонтальное.
