Cancer – Its stages, diagnosis, and prevention
Cancer is a disease caused by the growth of malignant cells in the body. The formation of cells can happen anywhere, from the brain to the pancreas. Several cancerous cells clustered together form a tumor. The tumor then grows in size, spreading to other parts as well. Some cancers we know of are fatal, while some can be cured with the help of surgery, chemotherapy, and other such procedures. Let’s take a look at the stages, diagnosis, and prevention. Stages of cancer There are different stages of cancer that are classified to understand how far it has spread and the degree of treatment that may be required. Based on this, there are two bases for differentiation. Based on the numbered system, there are 4 stages. Stage 0 cancer In this stage, the cancer cells are restricted to the area of origin and they’ve not spread to any other part. Stage 1 cancer Here, the cancer cells spread to the nearby areas, but not to the lymph nodes or other parts of the body. Stage 2 and 3 cancer This indicates that cancer has spread to nearby areas as well as lymph nodes. Stage 4 cancer Cancer has spread to other parts of the body.
