Inherited: The Genetic Connection to Cancer

Cancer is a complex disease that can be caused by a variety of factors, including inherited genetic mutations. Inherited mutations are passed down from parents to their children and can increase the risk of developing certain types of cancer.

How Inherited Mutations Cause Cancer

Inherited mutations can occur in genes that play a role in cell growth and division. When these genes are mutated, they can cause cells to grow and divide uncontrollably, leading to the formation of tumors.

There are a number of different genes that have been linked to inherited cancer, including:

• BRCA1 and BRCA2: These genes are responsible for producing proteins that help repair damaged DNA. Mutations in these genes can increase the risk of developing breast and ovarian cancer.
• TP53: This gene produces a protein that helps to prevent cells from growing and dividing uncontrollably. Mutations in this gene can increase the risk of developing a variety of different types of cancer, including lung, colon, and breast cancer.
• APC: This gene produces a protein that helps to control cell division. Mutations in this gene can increase the risk of developing colon cancer.

Who Is at Risk for Inherited Cancer?

Anyone can inherit a cancer-causing gene mutation, but some people are at higher risk than others. These include people who have:

• A family history of cancer
• Certain ethnic backgrounds
• A personal history of cancer

How to Reduce Your Risk of Inherited Cancer

There is no sure way to prevent inherited cancer, but there are a number of things you can do to reduce your risk, including:

• Getting genetic testing: Genetic testing can identify people who have inherited cancer-causing gene mutations. This information can be used to make decisions about medical care, such as whether to undergo more frequent cancer screenings or take preventive medications.
• Making healthy lifestyle choices: Eating a healthy diet, exercising regularly, and maintaining a healthy weight can help to reduce your risk of cancer.
• Getting regular cancer screenings: Regular cancer screenings can help to detect cancer early, when it is most treatable.

Inherited Cancer: The Bottom Line

Inherited cancer is a complex disease, but there are a number of things you can do to reduce your risk. If you are concerned about your risk of inherited cancer, talk to your doctor.
