Will Lynch syndrome increase my risk for other cancers?

Question

Hello doctor,

I was diagnosed with endometrial cancer two years ago and underwent a hysterectomy. My surgeon mentioned that my tumor was tested and that I have Lynch syndrome. I know Lynch syndrome affects cancer risk, but I never quite understood the full picture of what comes next.

I was told that patients with Lynch syndrome are at risk for multiple cancers, but now that I have finished treatment, I am wondering whether the syndrome will continue to cause problems going forward. My questions are:

Will Lynch syndrome increase my risk of developing other cancers after treatment?
Does being treated for one Lynch-related cancer reduce my risk of developing others?
Do I still have the same elevated risk?
What surveillance do I actually need for the rest of my life?

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and understood your concern.

I would like to reassure you that Lynch syndrome is not a disease itself but a genetic condition that increases the risk of developing certain cancers. These may include endometrial cancer, ovarian cancer, colorectal cancer, and several other cancers.

However, having Lynch syndrome does not mean that you will definitely develop another cancer. Likewise, having had one Lynch syndrome–related cancer does not mean that others will occur. You may never develop another cancer and continue to live a normal, healthy life.

However, because Lynch syndrome increases cancer risk, regular follow-up and screening are recommended. This may include routine colonoscopy and other surveillance measures based on your specific genetic mutation and personal medical history.

Regular breast screening, such as mammography, should also be continued according to standard recommendations for your age group. There is no need to live in constant fear, but ongoing surveillance is important because early detection provides the best outcomes. Your healthcare team can help develop a personalized screening plan that is appropriate for you.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.

Thank you.
