Most frequently asked questions about cancer
Cancer is the uncontrolled growth of abnormal cells in the body. Cancer develops when the body’s normal control system stops functioning. Older cells do not die and instead go out of control, creating new, abnormal cells. These extra cells can form a mass of tissue, called a tumor.
Cancer cells differ from normal cells in many ways that allow them to grow out of control and become aggressive. An important difference is that cancer cells are less specific and differently developed than normal cells. That is, while normal cells mature into very different cell types with specific functions, cancer cells do not they are notorious. This is one reason why, unlike normal cells, cancer cells divide non-stop.
There are two common types of tumors: benign (non-cancerous) tumors and malignant (cancerous) tumors. A benign tumor is composed of cells that will not invade other unrelated tissues or organs in the body, although it may continue to grow abnormally in size. Not all tumors are cancerous, but it is a good idea to see a doctor if any mass of tissue is visible.
In general, No Cancer is not a contagious disease that easily spreads from person to person. The only condition in which cancer can spread from one person to another is in case of organ or tissue transplant.
No, certainly not. Cancer can start almost anywhere in the human body including blood and other parts as well, which is made up of trillions of cells. Generally, human cells proliferate and divide to form new cells as the body needs them.
When cancer spreads, it’s called metastasis. In metastasis, cancer cells break away from where they first formed, travel through the blood or lymph system, and form new tumors in other parts of the body. Cancer can spread to almost anywhere in the body. But it commonly moves into your bones, liver, or lungs
Cancer can grow rapidly or grow at a slow rate. Having a rapidly growing cancer does not mean that you have a poor prognosis. Many of these cancers can be treated effectively. And some cancers do not necessarily grow rapidly, but are less likely to be detected until they metastasize.
Cancer is not a single disease, but more than 100 different diseases. (Breast cancer, for example, is a different disease than colon cancer). Fatal: Another term for cancer. Malignant Tumor: An abnormal mass of tissue.
Being aware of the common signs and symptoms of cancer is important to know about your health and to diagnose cancer or early precancerous conditions early. This may help in earlier detection and treatment.
Here are some common signs and symptoms that you should ask your doctor for appointment of screening:
Your doctor may use one or more methods to diagnose cancer:
No. Cancer and leprosy are two separate entities with different treatments.
Cancer is not a disease of the modern world. A study of Egyptian mummies and ancient skeletons has found little evidence that they suffered from cancer.
As people get older, their risk of getting cancer increases. The reason behind this is that the cells in our body get damaged. But cancer can occur at any age its vast entity of disease.
The risk is expressed both in terms of a percentage and as odds dependent on risk factors.
