Malignant growth (cancer) is a condition where a few cells in the body foster uncontrolled and spread to different locales of the body. Malignant growth might begin anywhere in the human body, which is comprised of billions of cells. Human cells typically develop and multiply (through an interaction known as cell division) to make new cells as required by the body. At the point when cells become excessively old or harmed to work appropriately, they die and are replaced by new ones. Each kind of cancer is characterized by abnormal cell creation and proliferation, which may result in metastasis, or the spread of the disease throughout the body. Each type of cancer is different. When a cell's DNA is broken, it may either repair the damage or undergo apoptosis, a kind of programmed cell death. When these systems are missing in cancerous cells it results in an abnormal rate of cell proliferation and the development of a tumor.
