Cancer is a complex disease that necessitates a multifaceted approach for treatment and management. While traditional therapies such as chemotherapy and radiation are crucial in fighting the disease, nutrition plays an equally important role in supporting the body during treatment and enhancing overall well-being. Diet can be a double-edged sword; what you consume can either bolster your immunity or drain it. This article will delve into the foods that should be avoided if you have cancer, revealing how certain dietary choices could affect your treatment and recovery.
Understanding the Role of Nutrition in Cancer
Nutrition is vital for everyone, but it becomes even more critical when you are facing a cancer diagnosis. A balanced diet can help maintain strength, reduce the side effects of treatment, and improve recovery times. Conversely, certain foods can exacerbate symptoms or even promote the growth of cancer cells.
