Early Onset Cancer Program

The Early Onset Cancer Program provides care and support for patients diagnosed with cancer between the ages of 18 and 49. Our mission is to reduce the burden of cancer and improve the quality of life for patients with early onset cancer and their families.

  • Trending

    Early onset breast cancer is the most common, but early onset gastrointestinal cancers have the fastest-growing new-case rates.

  • Gen X - Millennials

    Gen X (born 1965 – 1980) and Millennials (born 1981 – 1996) may be at higher risk of 17 different cancers compared to older generations. Rates could remain high for decades, so Gen Z and Gen Alpha could have similar risks as they age.

About Us

Early onset cancers (also sometimes called early age onset cancer) are any cancer diagnosed in adults under the age of 50.

They are defined this way because most cancers are diagnosed as we age, in our 50s, 60s, 70s, and beyond.

The Early Onset Cancer team prioritizes adults under age 50 with cancer through a dedicated program for their needs. Our new program is also the first of its kind to serve all early onset cancer patients, regardless of type, from one centralized hub.

The Early Onset Cancer Program highlights Yale Cancer Center’s vision to unify research and clinical care to eliminate the burden of cancer for all – especially for adults under age 50.

The Early Onset Cancer Program shines a spotlight on equity across all aspects of our program. We create meaningful partnerships with our community and intentionally include underrepresented groups in our research, outreach, and programs.

  • Cancer Care

    Our top priority is to find the best way to deliver exceptional care when it’s needed the most. We lead the way in helping early onset patients at Yale, Smilow, and across Connecticut access quality cancer care. This includes expanding connections to other important services, like genetic testing and family planning (fertility preservation).

  • Groundbreaking Research

    Our research priorities for early onset cancers are broad and far-reaching. We hope to discover why these cancers are becoming more common earlier in life, learn more about patient outcomes, and improve patients’ quality of life.

  • Support

    The Early Onset Cancer Program offers support related to cancer (sometimes called psychosocial support). We support patients and families by addressing cancer's impact on home life, work & school, family duties, and relationships through key partnerships across Yale Cancer Center, Smilow Cancer Hospital, and local community organizations.

  • Community

    We also work within our community to build strong relationships, raise awareness about early onset cancers, and improve access to the resources at Yale Cancer Center. The community’s voice drives our program creation and is always front-of-mind for us.

Our Programs
