Cancer is one of the leading health concerns worldwide, affecting millions of individuals and families each year. While lifestyle factors such as smoking, diet, physical activity and environmental exposure play a significant role in cancer development, genetics can also influence an individual’s risk.
A lot of people wonder if having a family member with cancer means they will get it too. The answer is not always. Most cancers are not passed down from parents to children. Some types can run in families because of genetic problems that are inherited.
Knowing your family history is a step in figuring out if you are at risk and making good choices about your health care. In this blog we will talk about how family history and cancer are connected, what warning signs to look for and when you should talk to a doctor.
Key Takeaway: Having a family history of cancer does not mean you will definitely develop cancer, but it may increase your risk and make regular screenings and medical guidance more important.
Understanding the Link Between Family History and Cancer
Cancer happens when cells in your body grow and divide much. This can happen because of problems that you are born with or that happen over time.
About 5 to 10 percent of all cancers are thought to be hereditary. These cancers happen because of problems that are passed down from parents to children and make it more likely that you will get certain types of cancer. Just because someone in your family has cancer it does not mean you will get it too. It could mean you are at a higher risk especially if a lot of your close relatives have had the same type of cancer.
What Does “Family History of Cancer” Mean?
Family history refers to the health problems that your biological relatives have had, including your parents, brothers and sister’s children, grandparents, aunts, uncles and cousins.
Doctors often look at your first-degree relatives, like your parents, brothers and sisters because you share a lot of genes with them. If a lot of people in your family have had cancer or if they got cancer when they were young it could be a sign of a problem.
Signs That Cancer May Run in Your Family
If one person in your family has cancer it is probably not a big deal. If a lot of people in your family have had the same type of cancer it could be a sign of a genetic problem.
For example, if a lot of women in your family have had breast cancer or if a lot of people have had colon cancer it could be a sign of a link.
- If someone in your family got cancer when they were young it could also be a sign of a problem.
- If someone in your family has had more than one type of cancer it could be a sign of a genetic problem.
- If the same type of cancer keeps happening in your family it could be a sign of a genetic problem.
Common Hereditary Cancer Syndromes
There are some problems that can make it more likely that you will get cancer.
One of these is called Hereditary Breast and Ovarian Cancer Syndrome. This happens when there are problems with the BRCA1 and BRCA2 genes. People with these problems are more likely to get breast cancer, ovarian cancer, pancreatic cancer and prostate cancer.
Another genetic problem is called Lynch Syndrome. This can make it more likely that you will get colon cancer, endometrial cancer, ovarian cancer, stomach cancer and urinary tract cancer.
There is also a problem called Li-Fraumeni Syndrom. This can make it more likely that you will get breast cancer, bone cancer, brain tumors and soft tissue sarcomas.
Which Cancers Are Commonly Linked to Family History?
Some types of cancer are more likely to be linked to family history than others. These include breast cancer, ovarian cancer, colon cancer, prostate cancer, pancreatic cancer, melanoma and endometrial cancer. Just because someone in your family has had one of these cancers it does not mean you will get it too. It could mean you are at a higher risk.
| Cancer Type | Often Linked to Family History |
|---|---|
| Breast Cancer | BRCA1 and BRCA2 gene mutations |
| Ovarian Cancer | Often associated with hereditary syndromes |
| Colon Cancer | Common in Lynch Syndrome |
| Prostate Cancer | Can run in families |
| Pancreatic Cancer | May be linked to inherited mutations |
| Melanoma | Can have a hereditary component |
| Endometrial Cancer | Associated with Lynch Syndrome |
When Should You Be Concerned?
You should talk to a doctor if someone in your family has cancer, especially if they got it when they were young.
You should also talk to a doctor if a lot of people in your family have had the type of cancer.
- If someone in your family has had more than one type of cancer you should talk to a doctor.
- If someone in your family has a known problem you should talk to a doctor.
- If someone in your family has had a type of cancer you should talk to a doctor.
The Importance of Genetic Counselling
Genetic counselling can help you understand your risk of getting cancer based on your family history. A genetic counsellor can look at your family history, figure out if you are at risk of getting cancer, explain what genetic tests are available and help you make a plan to prevent cancer. Genetic counselling can give you information that can help you make good choices about your health care.
Genetic Testing: Is It Right for You?
Genetic testing involves looking at your DNA to see if you have any problems that could make it more likely that you will get cancer. You might want to consider testing if a lot of people in your family have had cancer or if someone in your family got cancer when they were young. You might also want to consider testing if someone in your family has a known genetic problem. Genetic testing is a personal choice that you should make after talking to a doctor.
How to Reduce Your Cancer Risk
- Even if you have a family history of cancer there are things you can do to lower your risk.
- You should get check-ups with your doctor, including screenings like mammograms, colonoscopies and Pap smears.
