Which mechanism is the most common cause of death in cancer patients quizlet?
Metastasis is the process by which cancer cells spread to distant locations in the body. The majority of death associated with cancer is due to the metastasis of the original tumor cells.

How do chemotherapy and radiation destroy cancerous cells?
At high doses, radiation therapy kills cancer cells or slows their growth by damaging their DNA. Cancer cells whose DNA is damaged beyond repair stop dividing or die. When the damaged cells die, they are broken down and removed by the body. Radiation therapy does not kill cancer cells right away.
What are 3 types of carcinogens?
They can be divided into three major categories: chemical carcinogens (including those from biological sources), physical carcinogens, and oncogenic (cancer-causing) viruses.

Others may have breast conserving surgery (BCS), which involves removing the tumor and some of the surrounding healthy tissue.
Why is survival rate important?
However, it is essential to remember that a range of factors influence s survival rates and chemotherapy success rates. Many of these factors vary from person to person.
What is the treatment for bladder cancer?
Bladder cancer. Uterine cancer. Outlook. Chemotherapy is a powerful treatment that involves taking medications to damage cancerous cells. The goal is to prevent these cells from dividing and multiplying. This article outlines the use of chemotherapy drugs in the treatment of different cancers.
