The immune system of our bodies is constantly fighting against viruses and bacteria to keep us healthy. However, in certain cases, the immune system may also end up fighting some substances that are not always harmful. When this happens, you experience an allergic reaction. The allergens are the substances that cause the reactions. With a little carefulness, you can prevent the allergies effectively. The allergic development Even though an allergic reaction can vary from person to person, it generally progresses in the same five stages: Stage 1 The allergen enters your body through food, air, or touch, and contact the cells in your body. Stage 2 Your immune system creates immunoglobulin E, which is a type of antibody. Stage 3 This antibody enters your gastrointestinal tract or respiratory tract but does not do anything. Stage 4 The next time when you are exposed to the same allergen, the immunoglobulin E treats it as a harmful substance and reacts with it. Stage 5 24 hours after the reaction, the immune system cells move towards the areas that were affected to release certain chemicals to treat it. How to diagnose allergies Your allergies can be diagnosed by a doctor. Before visiting him or her, you must recognize the symptoms of an allergic reaction.

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.
