Chicago- Blood samples from women for whom breast cancer has come back had high levels of estrogen although most of them had been treated with estrogen blocking drugs, U.S. researchers reported.

The researchers said that the finding recommends women with a history of breast cancer to take extra steps like that of weight management and regular exercise in order to lessen their estrogen levels and reduce the risk of the cancer’s return.

Estrogen has been highly linked with the development of many breast cancers. However, very few researches have examined at the connection between high estrogen levels and cancer recurrence, particularly in women who are treated with anti estrogen drugs such as tamoxifen.

Washington– Blood thinners like that of aspirin can aid to fight cancer by preventing shelter to tumor cells that are wandering, a U.S. research team reported on Friday.

Experiments carried out on mice showed that using aspirin along with an experimental anti clotting drug reduced the rate of spread and growth of melanoma and breast tumors.

Blood contains cells known as platelets. These platelets feed and shelter the tumor cells in the bloodstream. This makes it easier for tumor to metastasize or spread, the research team said.

Inactivating the platelets can help to slow down or prevent the spread of tumor, the researchers wrote in the study published in the Journal of Cellular Biochemistry.

This study could lend support to other findings, which show persons who take aspirin or other similar drugs that have an effect on a gene and protein known as COX-2, including ibuprofen, aspirin and Celebrex (COX-2 inhibitor), have a reduced risk of certain cancers.
