Genetic cancers & testing
Most cancers develop because of genetic damage we sustain over a lifetime. When genes acquire defects that impact the cells’ ability to grow and divide properly, tumors form. Cancers that occur due to genetic changes we acquire over time are called sporadic. Approximately 70% to 80% of all cancers are considered to be sporadic.
Cancer that occurs in families more often than would be expected by chance is considered a familial cancer cluster. Familial clusters are believed to be due to a combination of risk factors including inherited susceptibility, environmental factors and chance. Cancer that results from genetic changes passed on from one generation to the next is considered hereditary. Approximately 5% to 10% of all cancers fall into this category.
A number of genetic defects have been found to be associated with hereditary colon cancer. These inherited genetic changes can result in an increased risk of developing colon cancer and other cancers. Lynch syndrome and familial adenomatous polyposis (FAP) are two examples of inherited syndromes that are known to be associated with an increased risk of developing colon cancer.
We offer genetic counseling services to those who may be at risk for an inherited cancer syndrome. Our experts provide personalized risk assessments, education and the opportunity for genetic testing when appropriate. These services and any necessary treatment are available at the Florina Cancer Center.

Patient education
This video is part of a Northwell Health patient education series on colectomy, which is the removal of all or part of the colon. The purpose of this video is to provide patients with a comprehensive understanding of how to best prepare for their upcoming colectomy surgery. The video provides useful information on how to prepare in the weeks and days prior to surgery.
