The Role of Diet and
Nutrition in Cancer Treatment and Prevention
Introduction
Cancer is a complex and
multifactorial disease that affects millions of people worldwide. While
advances in medical technology have improved cancer treatment outcomes, there is
still much to be said for the role of diet and nutrition in cancer prevention
and treatment. A healthy diet rich in essential nutrients can help protect
against cancer, while a poor diet can increase the risk of developing this
deadly disease. In this article, we will explore the role of diet and nutrition
in cancer treatment and prevention and provide practical tips for incorporating
healthy eating habits into your lifestyle.
The link between diet and cancer is
not a new concept. Studies have shown that certain foods and nutrients can help
protect against cancer, while others may increase the risk of developing the
