What is Cancer?

The human body is made up of Cells. Each cell in our body must go through several controlling processes, regulations, and rules as it starts its life, grows, and dies. In most cases, some genetic damage to the genes causes failure in these controlling mechanisms, which starts cells’ movement from normal to abnormal state and starts the onset of I disease, which we call cancer. When this occurs, the abnormal cells begin to multiply aggressively, which is way faster than normal multiplying. This aggressive multiplying and the failure of controlling mechanisms disturb the normal life cycle of cells and apoptosis.
Our body is made up of trillions of cells; thus, cancer can start anywhere. In many cancer cases, a solid mass or tumor is created, which means these cells can migrate to nearby organs and infect them, yet in other cancer cases, no mass or tumor is indicated. For example, breast cancer mainly forms a tumor, while other cancers, such as blood cancer and leukemia, generally do not create a tumor. In these cancers, some cells can break off and migrate to distant organs in the body using blood or lymph nodes and form new tumors far from their origins. This is known as metastasis. These cancers are called malignant. Tumors, solid masses, and cancers which do not spread to other organs are called a benign tumors. In these cases, tumors do not regenerate after the removal of the infected organ, whereas malignant tumors sometimes do. Most benign tumors are not life-threatening, but yet again, some are life-threatening, like brain tumors.
