Is the incidence of breast cancer currently rising?
False. The incidence of breast cancer steadily increased from the 1980s until the 1990s. The increased incidence in the 1980s has been partly attributed to early detection due to increased breast cancer screening with mammography during this time period. The incidence leveled off in the 1990s, began to decline starting about 1999 until 2003, and now has plateaued according to the National Cancer Institute Surveillance Epidemiology and End Results (SEER) data. The reason for this decreased incidence is unclear and may only become evident over time. According to the SEER data, it is projected that 246,660 women will be diagnosed with breast cancer in 2016, representing 15% of all cancer, and that 40,450 women will die of cancer from breast cancer.
