CANCER CELLS VERSE HEALTHY CELLS
The cells in our body are always replicating through the process of cell division known as mitosis. The cells growth is regulated, meaning that cell division only occurs when cells are damaged, lost, or worn out. However, some cells such as cancer cells lose control of cell division and reproduce uncontrollably. They lose their control of replication when the gene, in which controls the cell to stop growing at a certain point, is lost or not present. The figure at the right shows the difference in the process of the cell division between a normal cell to a cancer cell. The normal cell replication is even, while the cancer cell replication is nonstop. Neoplasm, an abnormal growth of a tissue, forms a mass referred to as a tumor. There are two types of tumors, malignant and benign. Malignant tumors are cancerous; they cause major health concerns as metastasis starts to take place. Malignant tumors rapidly spread throughout the body, attacking tissues and the surrounding regions. The only cure for this tumor …show more content…
Radiation is involved in radiation therapy. Radiation therapy can cure cancer and relieve symptoms by breaking the DNA inside the cancerous cells using beams of high-energy waves called radiation. Another cancer treatment is chemotherapy, chemotherapy works by using anticancer drugs to cause various damage to cancerous cells ; as this takes place, the cancerous cells loses its ability to grow and reproduce. Many side effects occur due to the process of chemotherapy. According to www.cancer.net/navigating-cancer, it lists the various side effects, “Chemotherapy sometimes causes these types of pain: mouth and throat sores, diarrhea, nausea and vomiting, constipation, blood disorder, and nervous system effects.” Chemotherapy causes many side effects because it can harm the healthy cells in the body while harming the cancerous cells; therefore it causes these side
