WHAT IS NORMAL FUNCTION OF CELLS?   Every human body consists of billions of small cells. These form different tissues and organs such as skin, bone, blood, liver and many more. The cells in these organs have a variety of functions, the skin cells provide protection for the body, the blood cells transport nutrients and oxygen, the muscle cells enable movements and so on. The cells of the body have varying life spans. Old cells die and are replaced with si...

HOW DOES CANCER DEVELOP? Cancer is thought to develop as a consequence of genetic damage in normal cells. The damage can be congenital (10-15 percent of cancer cases) or be caused by, for example, external factors. The cell contains genes which in turn contain germ plasma (DNA) that determines how the cell’s proteins are to be produced. Cancer develops when a string of mutations take place in genes that govern the cell’s ability to grow and divide. These mutations often lead to a...

One of the most important cancer treatments is that the cancer is surgically removed (surgical treatment). Malignant tumors, such as cancerous growth and sarcoma, are traditionally treated primarily by surgery. This is done to prevent cancer growth. Often, some healthy tissue must also be removed around the cancer. This is done to prevent the spread of the tumor. Nowadays, attempts are made to remove as little healthy tissue as possible. For example, the goal is to operate breast cance...

Irish researcher Arvind Negi (National University of Galway) asked on the science channel ResearchGate (https://www.researchgate.net/ ) why a cancer cell both develops its own acidity and thrives in an acidic environment. He sparked quite a lively discussion. Here is a summary of the discussion....
