  • 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.

Large, Diverse Study of Thyroid Cancer Patients Uncovers Wide Disparities in Survival Among Adolescent and Young Adult African Americans and Hispanics

Barriers to quality treatment and follow-up care may contribute to poorer outcomes. 

FREMONT, CA (April 15, 2015) -  Over the past forty years, thyroid cancer has ranked consistently among the top three cancers affecting adolescents and young adults. Prognosis is generally excellent, but some young thyroid cancer patients are at higher risk of mortality due to place of residence, racial/ethnic background, insurance status, and factors such as age and gender, according to researchers at the Cancer Prevention Institute of California (CPIC).                                                                                                                                                                                           

Men fare worse than women. In fact, adolescent and young adult males with thyroid cancer are two and one-half times more likely to die from their disease than female patients in the same age group.

The disparities were even more striking when the researchers considered racial/ethnic background of the young men and women. African Americans and Hispanics were six times and three times more likely, respectively, to die from thyroid cancer than Whites.

Age made a difference too. Younger patients – those diagnosed between the ages of 15 and 29 -- fared better than those who were over 30 at time of diagnosis. Patients between the ages of 35 and 39 experienced higher mortality, even if their cancer was caught early.

 Place of residence also played a role.  Adolescent and young adult men residing in low socioeconomic or non-metropolitan areas were more likely to die from their disease.  In addition, both young men and women residing in low socioeconomic areas experienced worse survival from other cancers and non-cancer related causes.

“The findings suggest that barriers to obtaining high-quality treatment and follow-up care may contribute to poor outcomes for adolescent and young adult thyroid cancer patients of low socioeconomic status, as well as young men who live in non-metropolitan areas,” said Theresa Keegan, Ph.D., a research scientist at CPIC and lead author of the study. “Such barriers may include lack of health insurance, financial burden of cancer treatment and care, and lengthy travel time to health care facilities.”

“Young men also are less likely to receive routine health care, whereas the adolescent and young adult women may see their physicians more frequently during their reproductive years, regardless of socioeconomic status,” Dr. Keegan noted.

In more recently diagnosed patients who had information on health insurance, those with public insurance or no medical insurance were more likely to die of their disease or other non-cancer causes, the researchers reported.  Insurance status has been found to be an important factor influencing stage at diagnosis, treatment and outcome.

"Many young, uninsured patients are not diagnosed until their cancer has already metastasized. They also are less likely to receive adequate treatment,” Dr. Keegan said.

Thyroid cancer patients are at risk for developing several types of subsequent primary cancers, including stomach, colon, breast, kidney and others. While the risk is the same for men and women, adolescent and young adult women were more likely to die from a subsequent cancer. This finding may indicate a predisposition to cancer and should be further explored, the researchers noted.

Thyroid cancer has been on the rise in the population as a whole for the past 30 years, with a particularly dramatic increase in incidence since 2001.

The study, “Socio-demographic disparities in differentiated thyroid cancer survival among adolescents and young adults in California,” has been published in the online edition of the journal Thyroid. In addition to Dr. Keegan, authors include CPIC researchers Li Tao, Ph.D. and Pamela Horn-Ross, Ph.D. (recently retired); Raymon H. Grogan, M.D., Michael G. White, M.D. and Kenan Onel, M.D. of the University of Chicago; and Helen M. Parsons, Ph.D. of the University of Texas Health Science Center at San Antonio.
