Mobile Mammography

Welcome to The Big Pink Bus

Thank you for visiting Lone Star Circle of Care’s Big Pink Bus page.

We are excited to announce a major milestone in our commitment to women’s health. In February, we anticipate welcoming a brand-new Big Pink Bus, which will replace our current mobile unit! During this transition period, we will not be able to provide mobile mammography services. In the meantime, we can assist you with finding an imaging location near you. Thank you for your patience.

Lone Star Circle of Care’s Big Pink Bus provides early breast cancer detection services to women throughout Central Texas. The Big Pink Bus offers low-cost or free 3-D digital screening mammography to most women, regardless of insurance status or ability to pay.  

Early detection of breast cancer is key to survival. When breast cancer is caught early, a woman’s 5-year survival rate is almost 100%. If you are a woman aged 40 and older, talk to your health care provider about regular screening mammography.

The Big Pink Bus team includes a program director, mammography techs, patient navigators, bus drivers, and a coordinator.

Who Can Be Screened

You can get a screening mammogram on the Big Pink Bus if you:

  • Are age 40 and older
  • Are uninsured, or have coverage from MAP, MAP Basic, or select commercial insurance
  • Have not had a mammogram in the last 365 days
  • Are not pregnant or breastfeeding
  • Are not experiencing breast issues such as lumps, discharge, or pain
  • Can independently walk up and down stairs

Mobile mammography is not right for everyone. You may need a different type of mammogram if you are experiencing breast discharge, pain, or a lump. Please talk to your health care provider if you have these symptoms. 

If you don’t have health insurance, Lone Star Circle of Care can find out if you are eligible for our sliding fee scale or programs that will pay for your screening mammogram on the Big Pink Bus. 

How to Schedule a Screening Mammogram

The Big Pink Bus currently serves these counties in Central Texas and does not serve counties beyond Bastrop, Caldwell, Hays, Williamson, Travis, Bell, and Burnet.

We Come to You

The Big Pink Bus travels Central Texas to serve women living primarily in Bastrop, Caldwell, Hays, Williamson, Travis, Bell, and Burnet counties, making regular stops in communities that need our service most. 

Screening mammograms are an essential tool for the early detection of breast cancer. By providing this service in a mobile setting, we make it easier and more affordable for women to get regular mammograms.

Bus Schedule

There are currently no available appointments on the Big Pink Bus. We will provide updates when service resumes.

COVID-19 Delays and Mammograms

The COVID-19 pandemic has been a difficult time for many of us, but it is essential that we don’t let it stop routine preventive care. If you missed your mammogram due to the pandemic, talk to your health care provider about getting back on track. By scheduling and keeping your mammogram appointments, you are taking the necessary steps to detect breast cancer early.
