What do cancer cells do?
Cancer is the uncontrolled growth of abnormal cells in the body.
Cancer develops when the body’s normal control mechanism stops working.
Old cells do not die and instead grow out of control, forming new, abnormal cells.
These extra cells may form a mass of tissue, called a tumor..
Do we all have cancer cells?
No, we don’t all have cancer cells in our bodies. Our bodies are constantly producing new cells, some of which have the potential to become cancerous. At any given moment, we may be producing cells that have damaged DNA, but that doesn’t mean they’re destined to become cancer.
Do cancer cells kill normal cells?
Normal body cells grow and divide and know to stop growing. Over time, they also die. Unlike these normal cells, cancer cells just continue to grow and divide out of control and don’t die when they’re supposed to.
What causes cancer to spread fast?
Cancer cells that have more genetic damage (poorly differentiated) usually grow faster than cancer cells with less genetic damage (well differentiated).
Can cancer cells disappear?
The process is typically called “spontaneous regression” or “spontaneous remission,” and a considerable body of literature confirms that cancer and benign tumors do indeed “disappear” and, in exceptional cases, patients are cured of the disease — in which case the phrase “miraculous healing” is sometimes invoked.
Do cancer cells still function?
Cancer cells don’t specialise Unlike healthy cells, cancer cells don’t carry on maturing or become specialised. Cells mature so that they are able to carry out their function in the body. This process of maturing is called differentiation.
