mammograms, and screenings. Asian American women over the age of 40 are the least likely racial/ethnic group to receive mammograms, and those who are diagnosed have more advanced stages of cancer compared to Caucasian women diagnosed. Many of these cancer burdens on the Asian American population are unnecessary and preventable with increased screening and vaccinations, especially because many cancers associated with this category are of infectious origin. Many Asian Americans also face physical barriers to health care access. Lack of transportation prevents many individuals from seeking out health care that may be further away from their residence. Furthermore, there appears to be an additional language barrier, with those that have limited English proficiency reporting even fewer mammograms than Asian Americans who are proficient at English. The proportion of Asian Americans that obtain screening tests for cervical cancer remain the lowest out of all the racial/ethnic groups as well, and again, language plays a role. Another unnecessary cancer risk is the failure to be vaccinated against hepatitis B viral infections to prevent liver cancer. Only 28.5% of Asian American youths are reported to have had a vaccination for hepatitis B versus the 73.4% among California's 7th graders. Asian Americans have a similar incidence of mental disorders as European Americans but are three times less likely to use mental health services. When Asian Americans do seek treatment, their symptoms are likely to be more severe and chronic when compared to European Americans. This is a result of initiating treatment at a later time and ending treatments prematurely. The underuse of mental health services is partially caused by the cultural stigma attached to mental illness, as well as a lack of bilingual and culturally sensitive physicians. Over two-thirds of Asian Americans are immigrants, with one-third of the total population possessing limited English proficiency. Immigrants and non-English speakers are especially vulnerable for low health literacy. Many Asian Americans are uncomfortable with communicating with their physician, leading to a gap in healthcare access and reporting. Even persons comfortable with using English may have trouble identifying or describing different symptoms, medications, or diseases. Cultural barriers also prevent proper health care access. Many Asian Americans only visit the doctor if there are visible symptoms. In other words, preventive care is not a cultural norm. Also, Asian Americans were more likely than white respondents to say that their doctor did not understand their background and values. White respondents
