Cancer is an illness that arises when cells grow out of control and spread to other areas of the body. Because the human body contains trillions of cells, this disease can develop in almost any organ.

Under normal circumstances, as noted by Cancer.org, cells grow and divide to make new cells when the body needs them. Old or damaged cells die and are replaced. At times, this orderly process goes wrong, leading to the formation of abnormal, damaged cells. These cells can gather into tumors (clusters of tissue) that may be benign (not invasive) or malignant (able to grow and spread to other parts of the body).

Modern advances now allow earlier detection before cancer becomes severe. These approaches look for specific changes in genes, proteins, or chromosomes. Genetic testing can help identify risks for several cancers, including:

• Breast cancer
• Uterine cancer
• Colon cancer
• Thyroid cancer
• Prostate cancer
• Pancreatic cancer
• Melanoma
• Sarcoma
• Kidney cancer
• Digestive tract cancer

What steps happen during genetic testing? Drawing on Healthline’s overview, here is the general process.

Step 1

Reviewing your family history and identifying who may benefit from genetic testing.

Step 2

Counseling, which explains how the test is done so you feel informed and less anxious.

Step 3

Completing a consent form that outlines potential benefits and drawbacks.

Step 4

Collecting a sample, which may be blood, saliva, or cells from the inside of the cheek.

Step 5

Receiving results in several weeks. A negative result means no known cancer-related genetic changes were detected. Even so, healthy habits still matter because lifestyle also influences cancer risk.

If the result is positive, your provider may recommend additional testing and discuss prevention or treatment options.

Sometimes results show a gene finding without clarifying which specific cancer type might develop.

Genetic testing can offer reassurance, especially if your family has multiple cancer diagnoses. It allows earlier preventive steps and may improve the chances of good outcomes.

Keep in mind, genetic testing can be costly, so plan your budget carefully, since many insurance plans do not cover it.
