Microwave Myth Debunked

The myth is, people do not need to worry about getting their food to proper temperatures throughout after a run through the microwave, because the radiation will kill bacteria.

This is an erroneous assumption and could lead to food poisoning. All microwaves do is make food hotter. The heat itself is the only thing killing germs. Microwaves are also notorious for cooking food unevenly. Experts recommend using food thermometers and checking various spots on the food when using a microwave, in order to ensure avoiding food poisoning issues.

Most microwave meals now contain similar instructions for their own legal protection and to avoid consumer complaints. The truth is that microwaves are perfectly safe in terms of radiation, but they are also not a magic box that will destroy all bacteria.

Chemotherapy and Hair Loss

Chemotherapy, sometimes referred to as chemo is the use of medicines or drugs to treat cancer. There are more than 100 chemo drugs. Chemo may be used to: Keep the cancer from spreading, slow the cancer’s growth, kill cancer cells that may have spread to other parts of the body, relieve symptoms such as pain or blockages caused by cancer and, in some cases, cure cancer. Different types of chemotherapy work in different ways and have different side effects. It can be administered as a pill, liquid, shot, IV, or rubbed on the skin.

Most cells in the human body divide using a process called mitosis. When a cell reaches the end of its lifespan, it gets destroyed in a pre-programmed process called apoptosis.

There are over 200 many types of cancer. All types are a result of unregulated cell growth. Cells that divide more rapidly than apoptosis can regulate is simply too much mitosis. The result is excessive tissue, known as tumors. Tumors can be localized or spread through the lymphatic system or blood stream.

Many chemotherapy drugs are administered in combinations and work by interrupting mitosis and most cannot differentiate between abnormal cancer cells and normal healthy cells. Because of this, any cells that multiply rapidly can also be affected by chemotherapy.

Fast growing cells are found in hair follicles, lining of the mouth, stomach, and bone marrow. Since these fast growing sites are also affected by chemo, the result can be hair loss, decrease in production of white blood cells, and inflammation of the digestive tract, etc. Luckily, healthy cells, like hair follicles and the others usually repair themselves, so hair loss temporary. Radiation can cause some of the same symptoms, but that story is for another day.
