Cancer is a broad term encompassing a range of diseases characterized by the uncontrolled growth and spread of abnormal cells. These cells can invade nearby tissues or migrate to other parts of the body through the bloodstream or lymphatic system, a process known as metastasis. The development of cancer begins with genetic mutations in cellular DNA, prompting normal cells to become cancerous.
Understanding the distinction between benign and malignant tumors is crucial in grasping the nature of cancer. Benign tumors are non-cancerous growths that remain localized and generally do not pose a serious threat. While they can sometimes grow to a considerable size, they do not invade nearby tissues or spread throughout the body. On the other hand, malignant tumors are cancerous and can invade surrounding tissues and metastasize, leading to the progression of the disease and complicating treatment efforts.
The prevalence of cancer cannot be overstated. According to the World Health Organization (WHO), cancer is a leading cause of death worldwide, accounting for nearly 10 million deaths in 2020. The most common types include breast, lung, colon, and prostate cancer. This widespread impact underscores the importance of understanding cancer, its prevention, and the available treatment options. With continuous research and advancements in medical science, there is hope for improved strategies to manage and ultimately defeat this pervasive disease.
