The Basics of Cancer
The Basics of Cancer
The term cancer refers to a wide variety of diseases caused by the uncontrolled growth of cells. These malignant cells ignore signals to stop growing and die and invade surrounding areas to form tumors and spread throughout the body. In contrast, healthy, normal human cells grow and replace damaged ones, and eventually die by design. When these normal processes go awry, cancer occurs. Luckily, early detection of cancer is possible, and the disease can be successfully treated.
DNA is present in every cell. Each cell has a unique copy of DNA, which contains the instructions for cell function, growth and division. In healthy people, these cells multiply and divide normally, and accumulate mutations as we age. These mutations cause cancerous cells to grow and spread, forming new tumors. These abnormal cells can’t survive without these changes. Fortunately, researchers have developed therapies that target these mutations and prevent them from spreading throughout the body.
The most common type of cancer is called metastatic cancer. In this type of cancer, the cells begin to multiply uncontrollably, causing the tumor to grow. When this happens, they become larger and start to invade nearby tissues. Eventually, they break away and spread to other parts of the body. In this way, cancer is a deadly disease. However, cancer can be successfully treated. It is the most common malady in adults.
Most cancers are nonhereditary. Inheritance of certain genetic defects is the main cause of hereditary cancer. Rarely more than 0.3% of the population carries mutations that cause a high risk for cancer. The risk of breast and ovarian cancers is increased by 75% in people with BRCA mutations. The chances of colorectal cancer are increased by 3% in people with Lynch syndrome. But there are other factors that increase the risk of developing cancer.
A cancer-related condition characterized by pain, sensitivity to light, and difficulty in breathing. The main causes of this disease are inherited. A person’s genes can influence the development of a tumor. A person’s genes also determine their chances of developing cancer. This is the reason why cancer is a major problem. There are many factors that can contribute to cancer, and the disease can affect your life in different ways. So, it’s very important to know your family history and to seek help when needed.
A cancer diagnosis is not a death sentence, but it’s hard to know how to deal with it. It is important to seek treatment for a cancer-related condition that is harmless. A patient with a tumor may be at risk for the disease. A doctor must first diagnose a cancer-related disorder before a person can be diagnosed with it. Only when a patient has a cancer-causing gene can he or she be diagnosed with it.
