Cancer is a huge problem that the modern world is facing. In the U.S. alone, at least one million people are diagnosed with some kind of cancer every year. Luckily, most of these cases are minor and can be cured easily. You can tell when a person is cured when there has been no trace of cancer in their body for 5 or more years. Medical developments are revealing more and more cures for cancer, but approximately half a million people are dying each year because of cancer.
What is cancer, you ask? It is uncontrolled cell growth. Unregulated cell division is called a neoplasm or a tumor. There are two kinds of tumors: benign and malignant. Both of these tumors can be fatal eventually if not removed before it grows to large for the human body. Cancer can develop in any cell type. Four main types of cancer are carcinoma, sarcoma, leukemia, and lymphoma. The most common area where cancer develops is in the skin cells. This kind is called skin cancer. Tanning beds and too much sun can may give you a tan, but later, it can develop into skin cancer. High fat diets may result in different kinds of cancer like breast, colon, and uterine. Smoking causes 85 percent of lung cancer. Since cancer is deadly and ruins many people's lives, it is important to research and understand.
