Why Early Cancer Detection Matters

Early cancer detection can make a meaningful difference in how quickly cancer is identified, how many treatment options may be available, and how confidently patients can move forward with care. Because some cancers can develop without obvious symptoms in their earliest stages, routine cancer screening and newer tools such as blood-based cancer screening tests can play an important role in finding signs of disease sooner. 

At Fontaine MD Aesthetics and Anti-Aging Medicine in San Diego, CA, board-certified physician Dr. James D. Fontaine offers the Galleri™ multi-cancer early detection blood test as part of a broader approach to proactive health and healthy aging. For patients interested in taking a more preventive approach to long-term wellness, understanding what early cancer screening can and cannot tell you is an important first step in deciding whether additional testing may be appropriate. 

How much does early detection of cancer really matter?  

Early detection can matter significantly because cancer is often easier to treat when it is found before it has grown extensively or spread to other parts of the body. Cancer screening can sometimes identify cancer before symptoms develop, creating an opportunity for additional testing, diagnosis, and treatment sooner than might otherwise occur. The impact varies by cancer type, which is why recommended screening schedules are based on factors such as age, sex, personal history, and individual risk. 

Early detection does not ensure a particular outcome, but staying current with appropriate and recommended cancer screenings can be an important part of preventive health care and may expand the treatment options available if cancer is found. 

Is there a blood test for cancer detection? 

Multi-cancer early detection, or MCED, blood tests are a newer type of screening technology designed to look for biological signals associated with multiple cancers from a single blood sample. These tests do not diagnose cancer, and a positive result requires additional diagnostic testing to determine whether cancer is actually present and where it originated. 

They also should not replace established screening methods such as mammograms, colon cancer screening, cervical cancer screening, prostate screening, or low-dose CT scans for eligible patients. At Fontaine MD Aesthetics and Anti-Aging Medicine, Dr. Fontaine offers the Galleri blood test as an additional screening option for appropriate patients interested in a broader approach to cancer detection. 

What kinds of cancers does Galleri test for? 

The Galleri test screens for a shared cancer signal associated with more than 50 types of cancer by analyzing patterns in cell-free DNA circulating in the bloodstream. The cancers represented in Galleri clinical studies include many that do not currently have routine screening tests. Examples include:  

• Pancreatic cancer 
• Liver and bile duct cancers 
• Ovarian cancer 
• Esophageal cancer 
• Head and neck cancers 
• Lung cancer 
• Colorectal cancer 
• Bladder cancer 
• Stomach cancer 
• Lymphoma 

Galleri can also screen for signals associated with several other cancer types, including breast, bone, cervical, gallbladder, kidney, prostate, and uterine cancers. However, its ability to detect a cancer signal varies by cancer type and stage, and false-positive and false-negative results are possible. A Galleri result that identifies a cancer signal is not a diagnosis and must be followed by appropriate medical testing. 

What can I do to lower my cancer risk factors as I age? 

There is no way to remove cancer risk, and some risk factors such as age, genetics, and family history cannot be changed. However, lifestyle and preventive health choices can influence the risk of developing certain cancers. Maintaining a healthy weight, managing your nutrition, staying physically active, avoiding tobacco, limiting alcohol, protecting your skin from excessive ultraviolet exposure, and keeping up with vaccines and age-appropriate screening can all play a role in long-term cancer prevention. 

It is also important to talk with your healthcare provider about family history, previous exposures, and other personal risk factors that may affect which screenings are appropriate for you. A proactive approach to healthy aging means paying attention not only to how you feel today, but also to opportunities to identify and manage health risks earlier.
