Understand Cancer

Understand Cancer

In honor of World Cancer Day, we shared information to help you better understand cancer all week.

Cancer causes 22% of deaths in the U.S., second only to heart disease, and you have an over 30% chance of being diagnosed with cancer in your lifetime.

Your Risk of Cancer

 

Cancer can start almost anywhere in your body and is when your cells fail to grow properly. When abnormal or damaged cells survive and continue to grow, they can become tumors.

How Cancer Cells Grow

 

Malignant tumors are masses of abnormal tissue that can spread into other healthy tissues around it. As they grow, they can also break apart and travel through your body, spreading the cancer further.

How Cancer Spreads

 

Cancer is genetic, so you can inherit genetic changes that cause cancer. They also can be a result of damage to DNA from being exposed to environmental issues, like tobacco or ultraviolet rays from the sun.

Genetic Risks for Cancer

 

There are over 100 types of cancer, and they’re usually named for the tissue they’re in or by the type of cell that they’re made of. Breast, colorectal, and lung cancers are currently the most common.

Early treatment can reduce your risk of death from cancer, and screenings, like exams, lab tests, imaging procedures, and genetic tests, can help you catch it before you display symptoms.

Screenings to Catch Cancer Early

 

Common cancer treatments include surgery to remove tumors, radiation and chemotherapy to kill cancerous cells, and immunotherapy that helps your immune system fight back. Learn more about other types of treatment.
