What is cancer?
Cancer is the name given to a set of diseases. In all cancers, some of the body’s cells begin to divide non-stop and spread to surrounding tissues. Cancer can start anywhere in the human body and is made up of trillions of cells. Normally, the body’s cells grow and divide to form the new cells that the body needs. As cells age or are damaged, they die and are replaced by new cells. When cancer occurs, the process breaks down. The cells become more abnormal and the old, damaged cells survive when they have to die and new cells form. These extra cells can divide non-stop and may lead to the formation of tumors.
Many cancers are solid tumors that are a mass of tissue. Leukemias, like leukemias, do not cause solid tumors. Cancerous tumors are malignant, meaning they can spread to nearby tissues
Find or attack. In addition, some cancer cells can travel to distant places through the blood or lymphatic system.
The body travels and forms new tumors away from the original tumor.
Unlike malignant tumors, benign tumors do not spread to nearby tissues. However, benign tumors
In some cases they may be very large and if they are removed, they usually will not grow back. While tumors
Malignant may grow again.

The difference between cancer cells and healthy cells
Cancer cells are different from healthy cells in that they allow them to get out of control and invade. The most important difference between cancer cells and healthy cells is that cancer cells are less specialized than healthy cells. That is, while healthy cells grow into a specific type of cell with a specific function and capability, cancer cells are not. This is one of the reasons why cancer cells, unlike healthy cells, continue to divide non-stop.

How does cancer develop?
Cancer is a genetic disease caused by a change in the genes that make cells function, especially how they grow and divide.
They control them. Genetic changes that cause cancer may be inherited from our parents.
It may also be the result of errors in a person’s lifetime that lead to cell division or DNA damage due to exposure to certain environmental factors. Environmental factors that may lead to cancer include things like chemicals in tobacco or the sun’s ultraviolet rays.
Each person’s cancer is a specific combination of genetic changes. As the cancer grows, other changes will occur. Even in one
Similar tumors, different cells may have different genetic changes. In general, cancer cells have more genetic changes, such as mutations in DNA, than normal cells. Some of these changes may result
Be cancer, not the cause of cancer.
