New breast cancer cases in the U.S. predicted to double by 2030

Recent government research projected an increase of new breast cancer cases up to 50 percent by 2030, as well as a change on its age distribution. The current statistic is one in every eight women will develop the disease during her lifetime. The surge will definitely be a new challenge to the medical field, however, researchers also found there will be a significant decrease on the different breast cancer subtypes.

According to one of the study's authors, Philip S. Rosenberg, PhD, of the National Cancer Institute, they combined both the invasive and in-situ types of breast cancer in the study, coming up with the estimation.

It is reported that breast cancer is the most common type of malignant tumors in the country, based on the data of previously diagnosed cases.

"Although breast cancer overall is going to increase, different subtypes of breast cancer are moving in different directions and on different trajectories," he said through a statement.

According to the Los Angeles Times, the proportion of invasive estrogen-receptor-positive cancers is still going to be at 63 percent while an increase from 19 percent to 29 percent is to be expected in estrogen-receptor-positive cancers that are not yet spreading to the other parts of the body.

There is an expected decrease on the estrogen-receptor-negative cancers, from 17 to 9 percent of total cases, but Rosenberg explained they are still trying to find the causes of the decline.

In the study, the researchers described changes in the age distribution of women with new breast cancers coming by 2030. They predicted an increase in rate is expected among women ages 70-84, from 24 percent to 35 percent. On the other hand, a decrease is anticipated, with 55 to 44 percent among women ages 50-69.
