The Role of Genetics in Cancer

Hello again! We’ve talked about what cancer is and the risk factors. Today, we will delve into a deeper aspect: the role of genetics in cancer. Don’t worry, we’re going to explain it in an easy to understand way.

Genetics and Cancer

We all have genes, which are parts of our DNA that contain the instructions for every function in our body. Sometimes genes can change or mutate, which can lead to uncontrolled cell growth and cause cancer1.

Inherited and Acquired Mutations

There are two main types of genetic mutations associated with cancer:

  • Inherited mutations: these are passed from parent to child. They account for about 5-10% of all cancer cases2. Some families have hereditary cancer syndrome, where mutations in certain genes increase the risk of having various types of cancer.
  • Acquired mutations: These occur during our lifetime and are the most common. They can be caused by factors such as exposure to radiation or certain chemicals, or they can occur by chance during normal cell division3.

Genetic Testing for Cancer

Genetic testing can help identify mutations that could increase your risk of developing cancer. If you have a family history of cancer, your doctor may recommend these tests4.

Prevention and Hope

Genetics plays a role in cancer, but it does not determine everything. There are many lifestyle factors that can influence our risk of developing cancer. Maintaining a healthy lifestyle is key, even if you have a genetic risk.

Remember, every day advances in science and medicine offer us more hope. Even if you are at high genetic risk, there are options for early detection and prevention.
