Annual Report of New Cancer Cases and Mortality for the Greater Bay Area

The total rates of new cancer cases and cancer mortality have continued to steadily decline, particularly for prostate, breast, colorectal, and lung cancers.
However, declines in these cancers were not observed in all racial/ethnic groups.

FREMONT, CA (October 2, 2017) — The rates of new cancer cases (incidence) and mortality, measured per 100,000 population, have decreased significantly from 1988 through 2014, the recent period for which data are available, according to the Greater Bay Area Cancer Registry at the Cancer Prevention Institute of California (CPIC). 

This newly released report summarizes the current rates for new cancer cases and cancer mortality for the most common cancers in the Greater Bay Area, with an emphasis on the most recent five years (2010-2014). 

The Greater Bay Area Cancer Registry, operated by CPIC as part of the California Cancer Registry, collects information according to state law on all newly diagnosed cancers in residents of nine Greater Bay Area counties (Alameda, Contra Costa, Marin, Monterey, San Benito, San Francisco, San Mateo, Santa Clara, and Santa Cruz).

From 2010-2014, 156,856 new cancer cases were diagnosed in the Greater Bay Area. In 2014 alone, 31,297 new cases of cancer were diagnosed. From 1988 through 2014, the rate of all new invasive cancer cases declined by 26.7 percent among males and 11.1 percent among females.

The five most common invasive cancers—breast, prostate, lung and bronchus, colorectal, and melanoma—accounted for over half of all newly diagnosed cancers.

According to Scarlett Lin Gomez, Director of the Greater Bay Area Cancer Registry, “We continue to see a decrease in rates of new cancer cases for many cancers in part due to better prevention, such as reduction in smoking, and greater uptake of screening measures, such as increase in colorectal cancer screening.” 

From 2005-2014, cancer mortality rates for the Greater Bay Area declined for all cancers combined by an average of 2.2 percent per year. 
The report segments new cancer cases and cancer mortality rates by cancer site, sex, and racial/ethnic background, and provides regional, statewide and national comparisons. Key 
highlights for the rates of new cancer cases and mortality for the five most common cancers among Greater Bay Area residents are listed below.

· Breast Cancer 
o Most commonly diagnosed cancer among Greater Bay Area females accounting for about one-third of all invasive cancers diagnosed annually.
o From 2010 through 2014, 25,015 new invasive breast cancers were diagnosed in women in the Greater Bay Area, and 125,077 in California. 
o Rates for white and Hispanic women have declined in recent years, while rates among Asian/Pacific Islander and black women have increased. 
o The Greater Bay Area rates of newly diagnosed breast cancers in all races/ethnicities were significantly higher than for California, but similar to the national rates.
o Breast cancer mortality rates declined in all racial/ethnic groups from 1988-2014. 
o Black women had the highest mortality rates (28.9 per 100,000), followed by white women (21.5 per 100,000).

· Prostate Cancer
o Most commonly diagnosed cancer among Greater Bay Area males.
o A significant decline in the rate of new cancer cases occurred among men in all races between 2010 through 2014, at an average of 13.5 percent per year. 
o Since 2012, the U.S. Preventative Services Task Force has recommended against screening in all age groups which has likely impacted the rates of new cases. Compared to all of California and nationally, Greater Bay Area males had a significantly higher rate of new prostate cancers diagnosed among whites, Hispanics and Asian/Pacific Islander males
o The rate of new cancer cases among blacks were slightly higher in the Greater Bay Area than California, but much lower than national rates.
o Prostate cancer mortality rates have steadily declined for all racial/ethnic groups by an average of 3.6 percent per year since 1991. 
o The prostate cancer mortality rate in black males was nearly five times the rate in Asian/Pacific Islander males, triple the rate in Hispanics and twice the rate in whites from 2010 through 2014.

· Lung and Other Smoking-Related Cancers
o The rate of new cancer cases for all Greater Bay Area residents combined continued to decrease by an average of 3 percent per year from 2007 through 2014.
o Despite declining rates, lung cancer continues to be the second most common cancer diagnosis among males and females in the Greater Bay Area.
o Lung and bronchus cancer is still a top contributor to cancer deaths, linked to 22.3 percent of all male cancer deaths and 21.6 percent of all females cancer deaths from 2010-2014.
o New lung and bronchus cancer cases and mortality rates were highest among black males and females.
o Cancers known or thought to be smoking-related include cancers of the lung, oral cavity and pharynx, esophagus, stomach, colorectum, liver, pancreas, larynx, bladder, kidney and acute myeloid leukemia. 

· Melanoma
o Second most common invasive cancer diagnosed among white males in the Greater Bay Area. In other U.S. populations, melanoma ranks fifth.
o The rate of new cancer cases is almost eight times higher among whites than Hispanics, and extremely low among blacks and Asians/Pacific Islanders.
o From 2008 through 2014, the rate of new cancer cases increased at an average of 3 percent per year. This rate of increase was significantly lower than the 8.2 percent average increase observed from 2002-2008. 
o Over the past decade, the rate of new melanoma cases diagnosed among whites has been significantly higher and increased more rapidly in the Greater Bay Area than in California overall. 
o Melanoma mortality rates decreased slightly since 1988 for all races/ethnicities. The rate was three times as high among white men, compared to white women, a difference that is poorly understood.

· Colorectal Cancer
o Third most commonly diagnosed cancer among Greater Bay Area males and females.
o The rate of new colorectal cancer cases was higher among males (40.5 per 100,000), than females (32.2 per 100,000).
o The rate of new cancer cases has declined among men and women in all racial/ethnic groups.
o Colorectal cancer mortality rates have declined substantially over the past 27 years in all racial/ethnic groups.

The Cancer Prevention Institute of California is a nonprofit organization dedicated to preventing cancer and to reducing its burden where it cannot yet be prevented. We are the only freestanding research institution working solely to prevent cancer using extensive population data. Our researchers study a wide range of cancer risk factors, such as racial/ethnic background, socioeconomic status, age, occupation, gender, genetic predisposition, geographic location, environment and lifestyle to determine how these factors affect frequency, distribution and types of cancers.
