Genetics play an important role in the development of cancer. Many people inherit certain gene changes that increase their risk, while others develop mutations during their lifetime. In this blog, you will learn how genetics influence cancer, why genetic testing matters, and how doctors create personalized treatment plans based on a patient’s genetic makeup.
Genetics play a significant role in cancer development. In this blog, we’ll delve into the hereditary factors that increase the risk of cancer. We’ll discuss genetic testing, counseling, and how personalized treatment plans can be tailored based on an individual’s genetic makeup.

Cancer is not a single disease — it is a group of more than 100 different diseases caused by unregulated cell growth. One of the key factors behind these diseases is the role of genetics in cancer development. When certain genes that control cell growth, repair, or death become abnormal, cells can start to multiply uncontrollably. These changes may be inherited or acquired over a lifetime. Cancer.gov+1
Understanding how genetic mutations and alterations lead to cancer helps patients and families make better decisions about screening, prevention, and treatment. Therefore, this article explains the main genetic causes of cancer, the difference between inherited and acquired mutations, and why early detection matters.
Why Early Screening & Expert Care Matters
Genetic changes often remain silent for years. Therefore, early screening is essential, especially if you have:
-
A family history of cancer
-
Chronic digestive problems
-
Unexplained weight loss
-
Abnormal growths or long-term pain
At Gastro Clinic Ahmedabad, we offer expert GI cancer evaluation, genetic counseling guidance, and modern diagnostic services. Early diagnosis gives patients more treatment options and better outcomes.

How Genetics Influence Cancer Development
Cancer begins when cells grow in an uncontrolled way. Normally, genes inside each cell guide growth, repair, and death. When these genes stop working properly, cells may start multiplying too quickly. As a result, tumors can form and spread.
These genetic changes happen in two major ways. Understanding both helps patients make informed decisions about screening and treatment.
1. Inherited (Hereditary) Mutations
Some people are born with abnormal genes that come from their parents. These genes stay in the body from birth. They may increase the risk of cancers such as breast, colon, stomach, or liver cancer. However, having an inherited mutation does not mean cancer will definitely develop. With the right screening and lifestyle choices, many individuals remain healthy.
2. Acquired Mutations (Develop During Life)
Most genetic changes occur gradually as we age. Factors such as smoking, pollution, infections, alcohol, obesity, and long-term inflammation can damage DNA. Over time, this damage can change how cells behave. Because these mutations develop slowly, people often do not notice symptoms until much later.
Why Genetic Testing and Counseling Help
Genetic testing can identify harmful mutations early. This information helps doctors recommend the right screening schedule and preventive steps. Along with testing, genetic counseling provides emotional support and explains how gene changes affect you and your family.
Doctors can also use genetic information to create personalized treatment plans. These plans focus on targeted therapies that work better for specific mutations.
