What Causes Cancer?

Cancer is one of the most feared diseases humans face. Ironically, many cancers can be prevented. Why? What causes Cancer? Can cancer be avoided? Related to this, what are Carcinogens?

What are the Main Causes of Cancer?

One of the key causes of cancer is damage done to genes over time. This accumulation of genetic damage triggers certain cells to multiply in an abnormal way. When this happens, the cells form what is called a tumor.

A tumor can be benign or malignant. Malignant means that the cells are growing and spreading, while benign means that no such spread has yet occurred. However, this can be misleading because if left untreated, even benign cells will eventually grow and spread.

Yet, what are the main causes of this degeneration of the genes which trigger cancerous growths?

What Triggers Cancer Cells?

Cancer triggers are well-known and each day, researchers uncover more factors which may lead to cancer. This is because the trigger is genetic. When certain substances and conditions are present, the genes become damaged. As the damage grows, the likelihood of cancer likewise grows.

These triggers are known as carcinogens. To date, researchers have identified over 100 KNOWN carcinogens. However, these are simply the chemicals and other factors which will, over time, cause cancer. Include in this list other strongly-suspected carcinogens, and the figure rises to a minimum 141 substances

Because the most important factor in protecting our health is knowledge, this list of KNOWN carcinogens is provided here. At Kymera, we are dedicated to both treating cancer AND fighting it at the source. This means we have an obligation to current and future patients to help them avoid things which can cause them to need our cancer treatment services.

Following is a list of known and strongly suspected cancer-causing agents. Learn more at Cancer.org.

Known and Suspected Human Carcinogens

The following is a comprehensive list of known and suspected human carcinogens. We encourage everyone to review this list, bookmark this page for easy reference, and do your best to avoid as many of these as possible. This is not an easy thing to do in our society, but the more of these carcinogens we can eliminate from our personal lives and our families, the lower the risk we have of developing cancer.
