Ok! Cancer - about one in three Europeans is confronted with this diagnosis during their lifetime. Scientists at the German Cancer Research Center DKFZ in Heidelberg are investigating the development of cancerous cells to find out how their growth is controlled and what goes wrong in a cancer c...
However, some mutations allow cancerous cells to grow unchecked 但是一些突变让癌变的细胞增长不受限制 and invade nearby tissues, 并侵入附近的组织 or even metastasize to distant organs. 甚至转移到远处的器官 Cancers become almost incurable once they metastasize. 一旦癌症转移就变得几乎无法治愈 And cancer...

Basal cell carcinoma is a common, but easily treated form of skin cancer that begins in the basal layer of the epidermis. The basal cells in this layer are the progenitor cells for the epithelial cells found in the skin.Answer and Explanation: Basal cell carcinoma does not form near the ...
normally are closed off to mature melanocytes (the cells that make melanin and give skin its color). In order to access these locked-up genes, the cells require specific proteins that act as keys. Without them, the cells do not form melanoma, even when they have cancer-associated DNA ...
According to the 2017 Michigan state university study, visceral fat releases fibroblast growth factor-2 protein( FGF2)that potentially causes non-cancerous cells to turn into cancerous ones. FGF2 stimulates certain cells that are already vulnerable to the protein and causes them to grow into tumor...
In the first case, an example would be when hands grow in the embryo they are initially webbed then cells between the fingers intentionally die off so the fingers are separate. In the later, when a cell becomes damaged and malfunctioning (and thus more likely to eventually become cancerous)...
Cells are programmed to commit suicide sometimes. For example, if a cell begins to become cancerous, there is a suicide pathway that gets activated to kill the cell before it starts dividing out of control; a few types of cancers involve the failure of the programmed cell death to occur. ...
“If you have more cells, that means that the risk that one of those cells… becomes cancerous increases,” says Daniela Tejada-Martinez at the Austral University of Chile. “So, if you are big or live longer, you have thousands and millions of cells that could become harmful.”...
Cells age mostly because they lose a bit of their DNA each time they divide. After around 40 or 50 divisions, they lose too much DNA to keep dividing. ... As they become cancerous, they learn how to not lose DNA during each division. The end result is thatthey can keep dividing for...
