ABSTRACT
At present, the incidence and mortality of cancers are increasing year by year, which has become a major global public health problem and the main cause of death of global population. In recent years, studies have shown that branched-chain amino acids levels play an important part in the incidence and prognosis of some malignant tumors, such as colorectal cancer, pancreatic cancer, liver cancer, breast cancer and so on. Therefore, this article summarizes the studies on the relationship between the level of branched-chain amino acids and cancers, providing clues for further exploration of the correlation between the two.
ABSTRACT
The incidence rate of ovarian cancer ranks the third among female malignant tumors, the mortality rate ranks the first and the prognosis is poor. Ovarian cancer poses a serious threat to the health of women's lives. The incidence of ovarian cancer is related to heredity, endocrine disorders and adverse lifestyle factors. In recent years, some scholars have carried out the impact of lifestyle, especially shift work, on the occurrence and development of ovarian cancer. Shift work can lead to circadian disruption, which affects hormonal balance in the body and may be a risk factor for ovarian cancer. This review summarizes four cohort studies and two case-control studies on the relation between shift work and ovarian cancer. The conclusion of the studies is inconsistent, suggesting that further researches are needed.
ABSTRACT
Ovarian cancer is one of the most serious gynecological tumors in the world, and its mortality ranks first in gynecological malignancies. The study found that metformin is not only used as a first-line oral hypoglycemic agent for the treatment of type 2 diabetes, but also has a certain inhibitory effect on the occurrence and development of ovarian cancer. In recent years, domestic and foreign scholars have carried out experimental and epidemiological studies on the relationship between metformin and ovarian cancer. This review included 7 cohorts and 2 case-control studies on the incidence and prognosis of metformin and ovarian cancer. The results suggest that the use of metformin may improve the prognosis of ovarian cancer, however, due to the limited epidemiological studies of the disease, its relationship with ovarian cancer still needs further exploration.
ABSTRACT
The incidence of cervical cancer remains high globally, especially in developing countries, which poses a serious threat to women's life and health. How to reduce the risk of cervical cancer has become the focus of the efforts of researchers in this field. Dietary patterns are analyzed based on the overall dietary status, and at the same time the interaction between nutrients and food is taken into consideration. Accumulating evidence suggests that dietary patterns play an important role in the prevention of cervical cancer. This review summarizes the relationship between different dietary patterns and the incidence of cervical cancer, and aims to provide a basis for more in-depth research in the future.
