Breast Cancer Cases Projected to Increase 50% by 2030

The National Institute of Cancer has announced that the incidence of breast cancer is likely to increase as much as 50 percent by 2030. The increase is expected to be most prominent in women older than 70. Certain types of breast cancer are also expected in higher incidence, while other types may decrease. Specifically, breast cancers that do respond to estrogen treatments are likely to be more common while cancers which do not will decrease.

The reason for the projected increase is partially due to the rapid swelling of the elderly population. By 2030 the number of women over 50 will have increased significantly, meaning more women will be at higher risk of developing estrogen responsive breast cancer. As present breast cancer research occurs in younger women, this may present a struggle for medical professionals as they the demographics change. Other factors which may contribute to the increase includes lifestyle factors such as obesity, lack of exercise, and exposure to hormones.

Though the reason for the decline in non-estrogen responsive breast cancers is currently unknown, Dr. Philip Rosenberg, a senior researcher at the National Institute of Cancer, expresses optimism about the trend saying,

“There could be a breast cancer-prevention clue in that decline. Understanding the ‘why’ behind the trend will be very important.”

Breast cancers which were not responsive to estrogen are often harder to treat, making the trend even better news. In addition Dr. Rosenberg points out that though the incidence of breast cancer is higher, the proportion of women with breast cancer is likely to decrease. Women are also more likely to survive breast cancer as a result of advances in treatment.
