  • We envision a world free from cancer.

    Our research scientists and their teams collaborate with colleagues around the world to conduct cutting-edge research using large data-sets to:
    • understand the causes of cancer
    • find ways to prevent it or detect it early
    • improve outcomes for cancer survivors 
  • Our mission began more than 40 years ago.

    Established in 1974 as the Northern California Cancer Program, the organization later became known as the Northern California Cancer Center. The name was changed again in 2010 when it became the Cancer Prevention Institute of California (CPIC), which reflects the organization's broader scope and demonstrates its large scale impact of preventing cancer before it starts.
  • We are an independent research institute and a valued partner to many.

    Through its collaborative approach, CPIC also serves as an asset to the nation’s leading cancer fighting organizations, including the National Cancer Institute, and to scientists worldwide, educators, patients, and clinicians, and is affiliated with the Stanford Cancer Institute.
  • We work hard to understand who gets cancer and why.

    Our scientists are frequent contributors to major scientific journals, and often present their findings at important cancer-related conferences. CPIC research has been covered by numerous local, national and international media outlets, such as The New York Times and The Washington Post.
  • Every case of cancer counts…and is counted.

    CPIC operates the Greater Bay Area Cancer Registry as part of the National Cancer Institute's Surveillance, Epidemiology and End Results program and the California Cancer Registry. As required by law, the registry gathers data from hospitals and doctors on all cancers diagnosed and treated in nine Bay Area counties. This information is used to produce cancer statistics and as a platform for research to understand cancer occurrences and survival. Our registry regularly earns Gold Standard Certification by the North American Association of Central Cancer Registries.
  • Our educational efforts reach people of all ethnicities and backgrounds.

    Our Community Education team provides important information to cancer survivors, health professionals and others through conferences and publications on many cancer-related topics including employment, patient advocacy, care giving, specific cancers, and treatments.

  • Breast cancer rates decline when hormone therapy is stopped.

    CPIC was first to report on the alarmingly high and increasing rates of breast cancer in the Bay Area and Marin County in the 1990s. In subsequent studies, CPIC found that when women stopped taking hormone replacement therapy, breast cancer rates declined immediately and dramatically. This showed that hormone therapy was a major contributor to the high rates previously reported and identified one clear path to breast cancer prevention.
  • Our work to associate tanning beds and melanoma prompted legislation.

    CPIC described increased occurrence of melanoma in young women in California, particularly in high socioeconomic areas, implicating use of tanning beds as one cause. This finding led to passage of the first statewide legislation to ban minors from using tanning beds, which should ultimately reduce occurrences of deadly melanoma in young persons.
  • Physical activity lowers your risk of Breast Cancer

    CPIC found that risk of breast cancer was lower for women engaging in more physical activity, such as walking and biking, doing household chores and yard work, and being active on the job. This shows a simple and practical way women can help prevent breast cancer from occurring.
  • Second-hand smoke increases the risk of lung and breast cancer.

    CPIC studies have shown that women exposed to second-hand tobacco smoke have a higher risk of lung cancer even if they don't smoke, and that exposure to household smoke increases their risk of breast cancer over and above the risk they incur from smoking themselves. These findings have been important in leading to anti-smoking legislation.
  • Vitamin D may reduce the risk of prostate cancer.

    CPIC assessed whether sun exposure, which is the main source of vitamin D, is related to prostate cancer risk. Using the difference in skin color measured on the forehead and upper underarm as an indicator of sun exposure, the study found that prostate cancer risk was reduced by 50% in men with a high sun exposure index, with an even higher reduction in risk noted in men with certain alterations in the vitamin D receptor gene.
  • Survival outcomes differ among Asian women of different ethnic backgrounds.

    CPIC was the first to show that breast cancer survival is not uniform across women of different Asian ethnicities, irrespective of how advanced the cancer was when diagnosed. In California, Korean, South Asian and Vietnamese women had the poorest survival after breast cancer, pointing to the need in these communities for better screening and/or breast cancer treatment.
  • Melanoma is on the rise throughout California.

    CPIC demonstrated that the rates of both early and more advanced melanomas were rising in all populations in California. This disturbing finding signals a true and alarming epidemic of this deadly cancer, and it has been cited over 245 times in the medical literature since 2009 because it identifies a major public health problem.
  • Survival disparities occur across many cancer types.

    CPIC showed that survival after follicular lymphoma, a common form of this cancer, is lower in poorer communities than in more affluent communities. This demonstrates population disparities in cancer treatment and shows a need in poorer communities for more access to skilled lymphoma care, including access to new successful drug treatments.
  • Our nail salon studies have widespread positive impact.

    CPIC found that California nail salons had higher than expected levels of carcinogens and other banned substances in the air, identifying the need for better standards and the importance of clarifying whether such exposures lead to cancer and other undesirable health outcomes.
  • Tailored approaches to healthcare are needed to address cultural differences.

    CPIC used two approaches to learn how best to help Vietnamese communities in California receive lifesaving colorectal cancer screening: one approach involved lay health workers directly educating the community on the importance of screening, and the other involved advertising about colorectal cancer screening. CPIC found that the use of lay health workers worked best to improve the screening rate, proving that organized community involvement improves colorectal screening practices among Vietnamese-Americans in California.
  • Lung cancer afflicts nonsmoking women more than men.

    CPIC was the first to show definitively that among nonsmokers, women were more likely than men to have lung cancer. Until this paper, there were no hard data about the incidence of lung cancer in nonsmokers. This study has been cited extensively as motivation for other research to understand the reasons why.
  • Genetic screening is especially important for African American and Hispanic women.

    CPIC was the first to study the level of BRCA1 mutations (genetic changes responsible for increased risk of breast cancer) in nonwhite women. This work found that young African American and Hispanic women with breast cancer had a particularly high prevalence of BRCA1 mutations, and signaled the importance to these communities and their doctors of screening for this mutation when indicated.

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.
