Some patients may not experience any symptoms at all until cancer has already reached an advanced stage, which then becomes more difficult to treat. Because symptoms of colon cancer are not always apparent, it makes it even more crucial for patients to schedule screening tests at a certain age or if they have any risk factors that may require earlier screening. Over the past several years, there has been a decrease in deaths caused by colon cancer. This is because patients have become more proactive in screening efforts when it comes to asymptomatic cancers.
